After some use I found a few stuff...
Blackscreen bug, but this is almost nothing since if it happens, as drnotor said somewhere here, you touch the screen and it wakes up. No big deal, also only happens when u try to wake up the phone just after puttin in to sleep.
(Also disabled CRT, didn't like it... )
Sluggish camera, well.. the camera is very very unstable and I use the phone mostly for social networking.. but there's no big deal, I use "mytubo" (aka instagr.am like for Android) and for normal photos I'm using "lgcamera"... works better than the camera app built in.
(There's no macro in built camera, also, in any camera app the zoom DOESN'T works... but is useless so, its ok)
Sluggish Gallery, up to now... this is also very annoying, since its so simple but also slow, I have tons of photos so the gallery takes forever to load.
I haven't searched for alternative apps...
Searched a bit about installing the stock LG camera app... but it doesn't work at all... up to what I read.
Now I'm wondering if there's a chance to get stock gallery app...
Everything else works perfect... =)
