A bit about the Samsung Galaxy J4 (2018)
As you can guess and wonder, is the new Samsung Galaxy J4 worth buying and unlocking? Is it better than his predecessor the J3 version?
The answer these questions will have to look into the phone specs, and the answer is: it depends, if you are on a tight budget I would really recommend it, I know it had some bad reviews but we don’t have to forget that it has a display of 1280 x 720 px resolution, which is decent. It has an Exynos 7 Quad 7560 chipset, 2GB of RAM, 16GB storage and a camera of 13 Megapixels to F/1.9 autofocus being able to film at 1080p with 30 fps and a frontal camera of 5 megapixels with f/2.2. Let’s not forget the most important part, because of the extra 0.5 Memory and a better processor it runs Android 8.0(Oreo) unlike his predecessor the J3 (2017) which can only run Android 5.1.1 Lolipop or other low-consum firmware.
In conclusion, it is around 30-40% better than his predecessor the J3 and is cheap so it is a YES for buying on a tight budget and also a YES for unlocking because of the reasonable price
