I have this phone for probably two months now. Overall I'm quite happy considering I have an old one for more than five years. However, I have two issues that are really bugging me. I think it might have occurred after the froyo update although I'm not sure. My first issue is the GPS. I takes much longer than before to find my location although when it does it is very accurate. Lots of time it's more than five minutes. It was much faster before. I don't know what's going on! Second I have 4G problem. If I serf the web with 4G, I'm fine. When I turn on my tethering more than 90% of the time, it will automatically revert back to 3G even if I have good connection (two or more bars). This is quite maddening to say the least. Was wondering if anyone has any ideas. Will a factory reset help??
