ATM, I have 3 problems (only one is REALLY a problem)
1) The phone constantly asks me to set my time zone. It's annoying. I set it to automatic and it asks me at least once a day (sometimes as much as 3 times). not big, but it sbouldnt do that.
2) Multitasking. It kills this phone. It is a reason not to get it and a reason to pick the SGSIII. That and the fact HTC wont fix it because sites like Android Central are condoning this.
3) No AOSP ROMs right now. Well, none that work perfectly at least. Apparently in order for both data and text we need the kernel source, which HTC hasnt released. they are obligated to release it in 3 months after the phones release, but that is a long way (also, is may 18th the release or is it May 25th or june 2nd?)
4) The screen is messed up. It doesnt bother me anymore, but if i press the screen harder than normal, the screen moves and you can here a clicky noise. I can press the screen and move it, and i dont think that should happen.
5) This isnt the phones fault, but the autobrightness lag is also annoying. I like the autobrightness setting and it's a shame i cant use it.
Besides these, i really like the phone. I know I'd love it WAY more if some of these problems werent there (im looking at you multitasking

)
