I've installed the new build on my 1520 and got annoyed by two main bugs: the first is the cellular data bug that make it un-controllable and the second was the start screen background image issue which makes it slides to left, so what did I do? I just reset my phone and these two bugs have gone.
I don't know whether some other bugs were fixed by this, try it and post the results

Hard reset? My 1520 same issues

[MrMHK]

Do key press hard reset with ! mark its better and wipe out SD

Power off
Hold Volume down 8sec
Wait for "!"
Volume UP
Volume Down
Power
Volume down

Do in exact order

[MrMHK]

even the method I did, it warned me that it'll wipe the SD. I took it out then return it back when finished

K thanks I'll give it a try. You also have probs with photos app? It's pretty much unusable for me

[MrMHK]

the photos app is not very good, slow and crashes a lot in addition to, can't control the live tile images
