i have wierd problem with my Grand Neo. The device is rooted. Yesterday i realized that my cpu do not work properly. What is going on ? The device blocks the cpu frecquents for normal mode is 1,2ghz to 1,2ghz (and phone goes hot after few minuts) and for power save mode 800mhz to 600mhz (this makes it very laggy). Before everything works fine. I use cpu nofrills app to change cpu value before and it works good. I do not know what to do and what to seaching to solve a problem. Can anybody help? Thanks for help anyway.
