i found a way to increase gaming performance of our phones. you will change resolution of phone. with this way you will get smooth framerate on heavy games like asphalt 7. what you need: - a rooted phone - a custom rom that supports changing dpi ( im using KING SLIM ROM from needrom) - ultimate dynamic navigation bar ( search it on google) - resolution change / density ( free in play store) - resolution changer lite ( free in play store) first of all install and enable ultimate dynamic navigation bar because when you change resolution of phone three hardware key at the bottom not working anymore. open resolution change / density app and set density to 255 and reboot your phone. now open resolution changer lite and select phones)16:9 resolution)576x1024 reboot your phone and enjoy!!!
