The sound quality of this phone is not upto the mark. its a bit low. it a user friendly phone, but you can use it only if it holds charge for an ample period of time. the battery drains very quickly. one of the worst smartphone. Its too hang while surfing and a bit light task. The device is slow and laggy and performs rather poorly. the rear camera captures noisy pics in low night and too slow to focus.
Internal memory available is only around 4 gb. which is not at all sufficient.can not stores our favourites apps. this phone has a lots of heating issues. so I would like you to prefer redmi or even u can switch to asus or moto, because it gives defibately better product than this j2 model.
