I just got my Evo yesterday and at work & at home I am having very fluctuating signal levels. Coming from AT&Ts network I had pretty much full signal at work & at home. Other users on the Sprint network in my office have full signal but the most I get is 2-3 bars. I have turned off GPS,WiFi,4g and still very low signal. Even if I exit the building and stand clear of any buildings it will constantly change from 1-2 bars to full signal. Is this something common on the EVO and I just shouldn't worry about it?? I don't know another EVO user to compare signal strength with in the Orlando area.
