The operation of my phone is highly degraded: Applications are no longer started when I press the icon, the display is unstable transition from one screen to another ... openings and closures applications. ... or more if wanted no action possible except standby with the Stop button.
I did a factory restore, without reinstallation of new applications it is always the same.
I found, however, that if the phone is charging battery even if it is full the situation improves.
