Anyone else having bugs/glitches on 8.1.2?

[Skulls138]

I know it's just a preview and so forth, but I'd like to know what are the most common bugs for this build. For me, I've been having some notifications with no sounds, very slow photo app, and my phone will black screen sometimes. Any ETA for the official update?

GDR2 isn't officially supported on anything but a couple of handsets (640/XL). It was only released as a stepping stone to Windows 10.

I don't really recommend installing it if you want to stay on WP8.
