Heat and high cpu frequency problem
The problem first happened when I upgraded my custom rom slimbean from 4.2.2 to 4.3
Since this upgrade my phone is 90% on 1400Mhz frequency and the phone temperature is always high when screen is off
I downgraded to 4.2.2 then to stock 4.1.1
And the big problem still excist
I checked the cpu usage and it is system_ui
And in the batteey stats it is android system
Is there any solution guys ?
Or it is a hardware problem and need to be replaced with a new board ?
