I use a Lava Iris 504 Q over 2 years there is many problem on the phone the camera quality is not upto the mark and very bad thing about the product is it is battery I have changed the battery two time s it will not stand even 2 hours the battery is showing me over our temperature and the very less memory for the applications.
The processing speed is very bad only one thing in the phone is it is IPS display is good when you’re using this phone in sunlight the phone gets too hard to hold in hand
