I have updated my phone to lollipop version manually. After updating, it is hanging like anything. I have to press start button for 5 or 6 times, then also it won't open. Some other times it will work normally. The screen also, it will hang for 10mins, after that it will work. This is very problematic issue. and whenever i open an application it's showing red blincks in the corners of the phone. I did factory reset, then also it is coming like that. The hanging problem is not resolved.
