This problem has not coincided with any new apps or updates.
I tend to shut down my phone every night, so I can't be disturbed at weird times (family emergencies can call the landline!), and to save battery power.
However, in the last few days, I can not switch on, without removing the battery for 5-10 minutes, then I have to hold Volume Up + Power to switch on. Everything works normally after that.
I have tried to close most apps and free RAM using CleanSweeper and unmount the SD card before shutdown. This didn't help.
Any general Android pointers on how to start troubleshooting this? I don't know whether this is a device specific problem, or software.
