Device: Xiaomi MI2 Version: 3.12.6 Hello everyone, My phone has been running great on the old version 3.3.29 for a long time. A friend of mine who also owns the MI2 kept pushing me to update as it had 'spectacular' improvements. Well, great.... now I have a huge bug which makes my phone unusable. After I flashed version 3.12.6 my phone started automatically pushing the back button over and over and over. To fix it I have installed CWM and did a full wipe and re-installed the rom. Didn't work. (The bug happened in CWM as well). I also tried to use the Xiaomi MiFlash to restore everything back to the Chinese version. At the moment, the problem is still there. It's strange as I would expect it to be fixed when I do a full flash of the Chinese Fastboot version, as the whole problem started when I first updated it to a newer version earlier today. Might it be a hardware problem and a coincidence that it happened at the same time? What do you guys think? Thanks.
