Well first off, I do love my phone, but the signal "freezes". The icon in the notification bar will say 3G but the download arrow will freeze and stay on. My signal is good and is uasually around 100 dbms where I live. I have to constantly turn it to airplane mode, wait until the phone responds, then turn airplane mode off.
The phone is stock and not rooted. I have tried *228 many times and also have done battery pulls.
Also, sometimes when I turn my phone off, it will take 10+ mins to power off, and rarely, it will get stuck vibrating until I hit a button and then it turns off.
