5.1 Version is not very stable...there is a lot of bugs.
Everything works for me, I have no problems with the Wi-Fi.
Lysergic Acid Thank you for a great job.
Does anyone have a similar problem in version 04/08.

You can not upgrade by OTA new nightly 20160205
I installed a new build every day, just wipe the cache.
At 1013 I had no problems with the reboot.
Currently testing build in 1014 and at the moment it is all good.
Lysergic Acid Thank you for the wonderful work of our Galaxy S2.
MX Player on 04/13 works well.
