Top 3 facts for the 2018 Samsung Galaxy J7 SM-J720F smartphone

Samsung Galaxy J7 (2018) SM-J720F smartphone is amazing and here are my  top 3 facts why

The Samsung Galaxy J7 (2018) will be released very soon and many Samsung fans are eager to buy the latest version of the J7. I personally like the J7 (2017) a lot and the J-series smartphones in general. In the recent couple of years they proved to be reliable devices offered at a reasonable price.

Problems with Samsung J5 fingerprint scanner - resolved

The problems and issues I've been having with the Samsung's J5 fingerprint scanner are finally resolved - see how

Samsung J5 fingerprint scanner
J5 fingerprint scanner - resolved

Many people have been reporting serious issues with the Samsung's J5 fingerprint scanner and mainly not being able to unlock the device with a single push/slide. And it was exactly the same story with my personal J5 (2017) which made me turn off the fingerprint unlock for good.

The resolution

It turned out that there is a simple solution for this problem and I will try to explain it in few words. Please note that the same may be applied for the J7 (2017) which uses the same biometric verification hardware.

When I first got my new Samsung J5 I applied the required number of fingerprints in order to use the unlock option but never thought that I was actually doing it in perfect conditions when my fingers were dry and device was as clean as new. It took me quite some time (unfortunately) to realize that I needed to repeat the same process but leaving the device a bit greasy and before washing my hands. Meanwhile I also kept the first "clean" pattern I had already in the device and saved this new one as well. This simple exercise made all the difference. Now almost 90% of the unlock attempts work fine from the first click/slide.

Well, that is the simple solution that worked for my smartphone. I would strongly advice other J5 and J7 owners to check if it works for them as well as this a good feature to have.

On the other hand I hope that the new J5 (2018) and J7 (2018) will have improved fingerprint scanners that won't need more than one pattern to be saved.

The 13MP rear camera - the biggest disappointment of J7 (2017)

Samsung Galaxy J7 (2017) has one bug disadvantage over the competition and that is the main 13MP camera

J7 2017 camera review

There are many discussions about the performance of the J7 and there are good and bad things. The comments left for its main camera (on the back of the phone) are pretty much always negative. And it is not because it "only" 13MP or bad color reproduction but rather something quite common for cheap and mid-range smartphones - stabilization and low light capability.

First look at the Samsung Galaxy J7 (2018) SM-J720F and SM-J720F/DS

Presenting the all new Samsung Galaxy J7 (2018) SM-J720F and SM-J720F/DS (dual SIM)

Samsung Galaxy J7 (2018) promises to be a successful continuation of the popular J-series that made huge impact on the smartphone market in the last couple of years. The next generation 2018 J7 will be offered in two dual and single sim versions - SM-J720F and SM-J720F/DS. One of the major differences consumers will find in the new model will be the larger 5.7 inch Super AMOLED display (compared to the 5.5 inch in the current J7 2017).

Samsung Galaxy J7 (2018) SM-J720F and SM-J720F/DS should be officially released in April

Design and Looks

The fact that there are so many rumors around the release of the J7 (2018) means that this model got really important in the recent years. I am not sure how much it contributes from Samsung's overall smartphone sales but I would guess the number is high.

The design and build quality of the 2017 J7 were really impressive. The unibody design using metal for the whole device but the display was appreciated by most most consumers. I personally used for almost a year the J5 (2017) which has the same design features as the J7 and it also felt high-quality and premium, people always got it mistaken for much more expensive smartphone.
For the 2018 edition Samsung will keep the same trend with the J7. We will see dedicated operating buttons at the bottom front part under the 5.6 inch Super AMOLED screen.

On the back side of the phone we will see the biggest change for the new model - dual-camera with flash. This feature is a first in a J-series smartphone which will attract more buyers, especially those who care about the quality of their photos.

That is all we can comment about the looks of the new device. Soon we will update you with more details about the exact dimensions.

Release Date

The J7 (2018) with code name SM-J720F was already certified by FCC (Federal Communications Commission). This means the Samsung Galaxy J7 (2018) SM-J720F and SM-J720F/DS will hit the stores very soon and we expect too see it for sale in May.


The J7 (2018) would be priced around $350. Price may vary on different markets, since this phone is sold globally.

Please let us know what you think about this new smartphone and stay tuned for more information, specifications and full review of the Samsung Galaxy J7 (2018).

Opel Vectra B on service for over 20 years

Opel Vectra B - still one of the best cheap second hand cars

Vectra B hatch
Opel Vectra B hatchback
Opel Vectra B was released in late 1995 and has been on service since then for millions of drivers all over Europe and Asia. The car was offered in 3 different body styles - 4-door sedan, 5-door estate and a 5-door hatchback. The hatchback version was very popular in UK where it was sold under the name of Vauxhall.

Vectra B - impressions when first released 

Back in the days Vectra B was one of the best looking mid-sized vehicles sold in Europe. It competed mainly with Ford Modeo, Mercedes C-class and VW Passat and all of them looked old and outdated when standing next to the recently released Opel Vectra B.


Vectra B was offered with a variety of engines. First line of Ecotec engines were first introduced in this car with displacement starting from 1.6 liters to big 2.5 V6. Gasoline engines were mostly sold in 1.6i 101 hp, 1.8i 115 hp and 2.0i 136 hp. There was also 1.6 mi (mono-injection) version with 75 bhp.
Diesels were limited to a 2.0 101 hp and 2.2 125 hp, both of which were very economical even by today's standards.

Buying a second hand car: Opel / Vauxhall Vectra B

 Many companies preferred the Opel Vectra B not only for its progressive design but also because of cheap maintenance. Company car fleets were later on sold to consumers and run on public roads even after more than 20 years.

First week with Samsung Galaxy J7 2017 - consumer review

Consumer review of Samsung Galaxy J7 2017 - best smartphone I have used so far

I've been using my Samsung J7 2017 for a week and it's already left a good impressions. The first thing I liked about this phone is the sleek look and metal casing. The phone has an almost perfect form factor. It's on the bigger end - 5.5'-inch display.

With its 5,5-inch display this phone may be bigger for most users. However, I was specifically looking for a bigger phone as it's more convenient for image viewing. The Samsung J7 is perfect on this level. It fits well in my hand. The grab is stable even without the protective case I've put on it to avoid scratches.

Why Samsung Galaxy J7 (2017) is the best mid-range smartphone today?

Samsung J5 and J7 are two of the most popular smartphones in the mid-range segment today - 3 things I like about it

Samsung Galaxy J7 (2017) smartphone
Top 3 things I like about the Samsung Galaxy J7 (2017)

Today we will have a short discussion about one of my favorite smartphones on the market the Samsung Galaxy J7 (2017). This is one very capable smartphone with 5.5 inch Full HD Super AMOLED display and very good hardware specifications. Here are the top 3 features I like about the J7 (2017):

Can't wait to test the new Samsung Galaxy J7 (2018) SM-J720F and SM-J720F/DS

  1.  Very good build quality - this last generation J7 looks and feels premium. It looks durable and metal body design feels sturdy. The phone itself is quite thin and weighs only 181 g (6.38 oz).
  2. Hardware and performance - Galaxy J7 (2017) is powered by an octa-core processor and had 3 gigs of RAM which by today's standards is considered average but this phone is quite snappy and doesn't lag even when heavy loads come. 
  3. Super AMOLED FHD display - I love how bright Super AMOLED displays are. The Full HD display in the J7 is amazing and I don't really miss the higher resolution of some other smartphones. The 5.5" size is one of the most preferred these days.

Samsung Galaxy J7 (2017) - first impressions

First impressions from the mid-range smartphone Samsung Galaxy J7 (2017)

After using the J5 (2016) for more than a year and the J5 (2017) smartphones for almost an year now I would say I am really impressed with the J-series. Samsung really does a great job offering smartphones for under $300 that have very good build quality on one hand and offer more than adequate performance on the other. It is the same story with the Samsung Galaxy J7 (2017) which can be found for less than $250 and believe me, that is one of the best performing 5.5-inch smartphones on the market today.

[gallery link="file" ids="2426,2427,2428"]

First impressions - build quality

Build quality of the J7 (2017) is on a very good level. It's entirely metal unibody design and 2.5 curved screen looks and feels solid in the hand. The J7 is really well made, it doesn't feel heavy, it is just the right size and weight and I am sure most consumers will love its form factor. Samsung offers this phone in few different color choices but I think the black version suits it best. Thankfully Samsung also offers their own TPU cases that fit really nice.


The 5.5 - inch Super AMOLED FHD screen of the J7 (2017) is one of the best in the segment. It is a Full HD screen and it is bright enough even in direct sunlight. I really prefer the Samsung's Super AMOLED display over the IPS screens of the competition because of the great color reproduction and amazing brightness. With 401 ppi density that is definitely one of the better screens out there.

Samsung Galaxy J5 (2017) – the best mid-range smartphone today


I will not spend too much on how the J7 performs in real world conditions as this is a first impressions article but I can assure you that the J7 has petty good hardware specs for most smartphone users. Powered by Octa-core 1.6 GHz Cortex-A53 processor and 3GB RAM this Samsung smartphone performs more than adequately even when multitasking and using some heavy applications. Assuming the J7 should do a bit better than the smaller J5 thanks to the better hardware I really believe that most consumers will be fine with this sub-$300 smartphone.
And yes, it has a 3.5mm headphone jack, micro SD card slot and dual-SIM tray, which are all good advantages over some of J5's competitors.


Samsung Galaxy J7 (2017) has 13MP front-facing selfie camera and a rear primary 13 MP, f/1.7 camera with autofocus. There is really nothing to complain from the front camera which has its own LED flash. I really hope that the rear camera in the next generation J7 (2018) would be a bit better than the current one. In good daylight conditions it does great shots but you should always keep the phone steady in your hands otherwise lot of noise shows up. Things may get really bad in darker conditions when the f/1.7  doesn't show its strengths and images are mostly blurry with no clear focus.


There are no complaints from the 3600 mAh Li-Ion battery whatsoever. It holds charge for more than 2 days of average use.
First impressions - conclusion

Well, compared to some of the recent releases from Huawei and other brands the J7 (2017) looks the underdog of the segment - no dual camera, no 4GB of RAM etc. But that is only on paper. Having tested most of these new releases I can assure you that Samsung's mid-range smartphone has the key components and exceptional build quality that make it stand out from the crowd. So, if you don't want to spend too much on your next smartphone and you are looking for quick and reliable smartphone I would strongly recommend you the Samsung Galaxy J7 (2017).

Opel Vectra C fuel consumption - real world test

Testing the optimal fuel consumption with the facelift petrol Opel Vectra C 1.8i

Opel Vectra C is a car that is still on service, more than 15 years after it was first released. We've already tested different versions of the last generation Vectra C and almost all of them proved to be quite economical in terms of fuel consumption.

The Test 
Lat week we tested petrol 1.8i Vectra hatchback in normal weather conditions and in extra-urban traffic we managed to achieve results of under 7 liters per 100 km. This is actually quite an achievement for mid-sized vehicle with 140 hp under the hood. Yes, you have to be quite gentle with the throttle but on a longer journey it will really pay out as you might save quite a lot. Of course the 1.9 CDTI engine runs on even less fuel but that is expected due to the diesel's better efficiency.

[caption id="attachment_2406" align="aligncenter" width="683"]Vectra C consumption Opel Vectra C fuel consumption[/caption]

Vectra C petrol – fuel consumption under 7 liters per 100 km

The very same Opel Vectra C 1.8i achieved 7.5-7.8 liters per 100 km in mixed cycle. Urban goes as much as 12.0-12.5 liters, which is a satisfactory result but far from perfect.
"Diesel engines have some good characteristics but I believe they will become obsolete in the next 10-15 years due to environmental reasons. Hopefully hybrids and hydrogen vehicles will get more advanced and will reach wider range of consumers." Fuel consumption under 7 liters per 100 km with 2008 Opel Vectra C – achieved

Test Conclusion 

In this test we proved that petrol vehicles without LPG systems can be also economical. You just need to be gentle on the gas pedal and avoid driving aggressively.

Where can I check the aircraft Wi-Fi’s username and password?
There are three places where you can check this information: a. The battery compartment on the aircraft (only the default Wi-Fi username and password can be found here);
b. The Settings option in DJI Assistant 2 or DJI GO 4;
c. The foam outer box (only the default Wi-Fi username and password can be found here).

How do I reset or modify Spark’s Wi-Fi username and password?
To reset, hold the power button down for 9 seconds until you hear the aircraft beep three times.
To modify, connect your mobile device to Spark, enter the DJI GO 4 app, and modify the Wi-Fi username and password in the Connection Help Menu.
(Note: If Spark is connected with DJI Assistant 2 on a computer, restart the aircraft before resetting the Wi-Fi username and password.)

My mobile device does not detect Spark’s Wi-Fi when I turn it on. What should I do?
This may be because Spark was previously connected to the remote controller. To prompt detection, power on the aircraft, then press down on the power button for six seconds until you hear the aircraft beep twice. This indicates that Spark’s Wi-Fi is now detectable on your mobile device.

How do I charge Spark?
Use the included USB cable to charge Spark. During charging, do not remove the battery from the aircraft.
Use the Charging Hub to charge three batteries simultaneously. If using the Charging Hub, you will need to remove the batteries from the aircraft and place them in the Charging Hub.

My newly purchased battery is not responding when I press the power button. What should I do?
New batteries are shipped in Hibernation Mode. In order to activate your newly purchased battery, charge it fully.

How long does it take to fully charge a battery?
When using a standard USB charger, it takes 80 minutes to fully charge a battery. When using a Charging Hub, it takes 52 minutes to fully charge one battery, 55 minutes when charging two batteries and 85.2 minutes when charging three batteries at the same time.

How often should I fully charge my Spark batteries?
It is recommended to fully charge Spark batteries at least once every three months.

When does a battery enter Hibernation Mode?
When a battery is less than 10% charged, it will enter Hibernation Mode after approximately six hours of nonuse.
When a battery is completely drained, it will enter Hibernation Mode within 10 minutes of turning off.

What functions can the power button perform?
a. Turning the battery on and off: Press the power button once, and then press again and hold it down for at least two seconds to turn the battery on or off.
b. Checking the current battery level: Press the power button once to check the current battery level.
c. Linking Spark and the remote controller: Hold down on Spark’s power button for three seconds, and release on hearing a beep. Spark’s front indicators will start to flash in red, signifying Spark and the remote controller have been linked.
d. Delinking Spark and the remote controller: In order to use your mobile device to control Spark, you will need to delink the aircraft and remote controller. Power on Spark, and hold down on Spark’s power button for six seconds until you hear it beep twice. Now Spark and the remote controller have successfully been delinked and you can search for Spark’s Wi-Fi on your mobile device.
e. Resetting Spark’s Wi-Fi username and password: Hold down on the power button for nine seconds, and release after hearing it beep three times. Your Wi-Fi settings will be reset to the factory default.
f. PalmLaunch: Power on Spark and place it on your palm with the camera facing you. Make sure your fingers are lower than Spark’s arms. Press the power button twice when the flight indicators start to flash green. The indicators will change to a slowly flashing yellow, and FaceAware will begin to recognize your face. The front indicators will turn to green if detection is successful, and PalmLaunch will be activated. If not, the indicators will flash red.

What can I do with the two USB ports on the Charging Hub?
You can charge two mobile devices or your Spark.

Updating Firmware
Can I use other apps while DJI GO 4 is updating?
No. If you do, the update will fail. You will then need to download the firmware and update again.

Why does DJI GO 4 remind me to reconnect to Spark’s Wi-Fi right before it restarts to complete the update?
Before the update is complete, Spark will need to restart. Once it does, reconnect your mobile device to Spark’s Wi-Fi. DJI GO 4 is just reminding you that you will need to do this for a successful update.

Can I disconnect from the internet once the firmware is downloaded successfully?

If the aircraft or the remote controller battery levels drop below 50% during an update, will the update fail?
No, but it is recommended that both have a high level of battery charge during the update.

What should I do if the aircraft and battery firmware versions are inconsistent?
Connect Spark to DJI GO 4, and the app will inform you of appropriate updates to ensure consistency.

What should I do if the update is really slow?
Please wait patiently and do not operate Spark or the remote controller during the update. Usually, it takes two minutes to update the remote controller and five minutes to update Spark. If the update process is taking much longer, please check your internet connection or move to a different environment. You could also restart Spark and the remote controller to begin the update again.

What factors could lead to an update failure?
a. Low battery level. Make sure the battery level is higher than 50%.
b. Powering off Spark or the remote controller during the update. If this happens, please restart Spark/remote controller and begin the update again.
c. Internet disconnection when downloading firmware.
d.Aircraft and remote controller firmware version inconsistency. Use DJI GO 4 to update the aircraft and remote controller to the latest version.
It is recommended that you use DJI Assistant 2 on your computer to update your aircraft.
Please note that Spark will restart once the update finishes.

AUX-in to CD30 in Astra and Vectra?

How to install AUX port to CD30 / CD30 MP3 in Opel Vauxhall Astra and Vectra

Probably many of you who read this post are proud owners of Opel or Vauxhall Astra, Vectra, Corsa or Signum. As good as these cars can be (not all of them of course) most of them come preset with the CD30 / CD30 MP3 audio system. Unfortunately this car audio system is quite outdated and even though it provides high-quality sound it doesn't have any useful ports for external sources. And believe me that could be a huge deal for many owners.

Today I am sharing with you an interesting tutorial for how to modify and upgrade the CD30 car audio to such that will be able to play external sources via AUX in port.

I hope you find these video tutorials useful. Please share your opinion in case you've fixed this issue in another different way and your CD30 works fine with other sources.

Honor 7 Lite - 3 big reasons not to buy this smartphone

Using the Honor 7 Lite happened to be a real struggle most of the time

I know the Honor 7 Lite is not an expensive phone but I really didn't expect it to disappoint in so many terms. Having used the phone for almost a year I can confirm that there are plenty of much better performing smartphones out there for the price of $200-250.

Weak points

  1. Display - not very bright and sometimes really unusable in direct sunlight. I know this is a weak point for many mid-range smartphones but still I expected the display to be just a bit better.

  2. Interface and usability - the Honor 7 Lite is really far from the best performers in this price segment. It is not very responsive at all and I constantly had connectivity issues. This is totally the opposite from what I can share of my Samsung J5 (2017) which has similar price but feels like much better phone in all aspects. The only thing that worked more then fine is the fingerprint scanner on the back of the phone.

  3. Camera - mediocre performing rear camera, really crappy low light shots.

Samsung Galaxy J5 (2017) – the best mid-range smartphone today

It is really a shame that Huawei didn't do a better job with the Honor 7 Lite. I believe it had the potential to be a good mid-ranger but that never happened. Alternatives from Samsung and Lenovo did much better in most categories and that is why I wouldn't recommend the Honor 7 Lite as a second hand purchase.
