I was just trying an app to read the cpu model, it says it`s an Samsung s5pv310 , now if you search for info on this cpu, it says the recommended maximum frequency is 1000mhz , and ours is set to 1200mhz max , I suppose Samsung knows what they are doing.
Ohh Yeah, I have the free Kaspersky mobile anti-virus 2011 , but i cannot use it as when i do a scan my cpu temperature starts to rocket it got to 46c + before i cancelled the scan, as i did not want to damage my phone or my hand
