This is the best budget phone for 12k. I found no lagging or hanging issues with it. It works perfectly for multitaskers and gamers. The snapdragon 625alomg with the 4GB ram does its job perfectly. The only drawback is the camera. It does not come upto the mark. The customisation in MIUI is very helpful like the three finger screenshot and one handed mode. The durabilty and build quality is also too good. I would personally reommend it to every one who is looking for a perfect budget phone
