Hello friends im using Samsung galaxy j5 prime about 6 months, but sometimes the back button was freez and not working, sometimes its hanging also.
sound quality: sound quality was fine also have equalizer on it but this supported when earphones plugged in, and speaker have low bass.
user friendly: best part of that mobile was it was easy to operated with one hand and best design.
design and style: build quality looks premium and and verry handy.
some other features: RAM 2gb, internal memory 16gb, camera sensor 13 mp rear, 5mp front camera, there is fingerprint sensor was slow as compared to other devices, having lacks of sensor on it it having only proximity and accelerometer sensor
but at the price of 14k it was not worth for it, some othe mobile such as mi4 and motoe3 provide best features
