Auto-Reboot

[WPCentral Question]

Hi, I have a Lumia 620, bought on 12tth Jult 2013, with WP8.1 Dev Preview.
Since the 30th of June I've noticed that sometimes my phone reboots automatically
and also when i shake it or take it in strange ways (ex. when I flip it).
What is the problem ?
It could be the removable battery ?
Thanks

Yes it's battery problem.. Use a paper piece to make your battery fit tightly
