Midnight crashes

[Sharzi]

My Xperia M has taken to crashing at midnight! It's done it about once a week for the last month or so. I'm waking up to find my phone has frozen at 23:59. The first few times I had it charging overnight so put it down to some possible odd power surge but it's done it since even off charge. I daren't rely on the alarm anymore and it's really inconvenient first thing in the morning having to mess about removing the battery to get it to shut down so I can power it back up. Any suggestions?

The only one I can think of is to perform a system repair as this will often fix issues - This will factory reset your phone

Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the onscreen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process

If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP

I have tried resetting my phone several times but still have this issue.  The phone freezes at 23 59 - this means that my morning alarm doesn't go off!  I then have to reboot the phone to get it to work again.

Exactly the same problem and unresolved so far.
