Here's what works after about 15 mins of leaving it on:
Hardware:
Phone calls - No signal for 10 mins, then Working, clear sound.
Voicemail (started working around 15 mins later)
SMS - Working in/out
Data - Not working - I haven't changed any settings. (do I need to?)
Wifi - Working, it might just be me, but seems more responsive overall.
Wifi Hotspot - Can't test until data works.
Camera - Working, takes pictures a bit faster. Much nicer app.
Video Recording - Working, kinda slowish switching to video mode
Video Playback - Working, smooth
Flash - Working
Sound - Working
Touch - Working
Software:
Phone App- Much nicer than gingerbread, finally people's faces for dailing starred people in one of the tabs.
Home Launcher - Trebuchet. *I Would like to see the stock launcher in there too. This one's functional, but a little laggy. I'd like to use the stock one to compare performance.
Web Browser - A little stuttery while loading, but buttery smooth once page is loaded.
Antutu Benchmark -7641, On VV3 I think it was 8000 something or other.
CPU Settings under performance - Not fully working. It sets only settings for cpu0 not cpu1 like it's supposed to. Also when the cpu min/max are different for each core, this phone's performance becomes more erratic.
Missing Software:
Visual Voicemail - Should be included. It's the only convenient app metro has lol
SmartShare - Many people don't need this, but if you have an LG Smart TV like me you do.
MetroWifi App - Would help temporarily so we can get data lol. Besides system apps can be disabled in jelly bean.
