At first I would like to comment, ’why to buy?’
Amazing(front & back) camera 1.9 F for sharper picture even in low light conditions; far better than(Sony Exmor) remember Exmor lens are found in high end phones.
Removal battery 3300 mAh powering the phone for two full days(normal usage).
Less preinstalled apps that dose not eat up the battery life.
Apps not used for more than three days are automatically notified to save battery.
Lightning speed - buffer free, fluidic surfing with Marshmallows 6.0. & Exnos processor for multitasking.
No heating issues* even after hours gaming and browsing.
OTG support.
Crystal clear sound and voice calls.
Vibrant display.
Micro SD dedicated slot.
’Why not to buy?’
No back light(bit disappointing), auto brightness and full HD screen.
No gyroscope( No problem as I am not a gamer).
Metal basel bit slippery and no Gorilla glass protection so you got to be careful.
Moderate ringtone sound and cant be heard if you are in noise polluted vicinity, so have your vibration on.
No finger print sensor.
No quick charging.
Second speaker near the rear camera lens is bit annoying.
Final verdict, you might get many more options and features in cheaper phones offered under 10 k in market but no proper service as Samsung.
J7- 6 a descent good looking phone under 16 k is worth it and stands tall rest of the odds.
