Can this be Battery Saver related?

[YLAP]

Just had a strange story with my mothers Galaxy Tab2 10.1 3G. On Sunday morning I've installed Battery Saver to her tablet, because it proved itself on my S4. Set two profiles, including night one to turn on midnight but without any notification (Sleep 1 minute / 30 Seconds at night, Optimized ON / Internet OFF at night, WiFi preferred). And the strange thing, tablet worked fine all day but exactly at midnight it restarted itself and stuck on never ending boot loop, keeping restarting without showing any UI. So the only thing I was able to do is factory reset from recovery menu...  My mom is so conservative user, she never installs any apps without me, and the only app I've installed that weekend was a Battery Saver. Coincidence?

Hi YLAP,

we certainly don't try to break devices, so I'd say it was a coincidence We don't even have root privileges to do any harm to the system. If you could try it again and see what happens, that'd be great. On some devices (like Nexus 4) there's a known bug (in the OS) that freezes wifi and the phone has to be restarted for wifi to work again, but it certainly doesn't need to be factory reset.

Thanks

I think in the same way as you I will try to check it once more, but it will be at least after two weeks. I have some plans to update Android version on that tablet when I'll visit my hometown again, so another factory reset won't hurt anything
