I have noticed some glitches with calls dropping and I don't think these instances are connected: 1) Sometimes I cannot dial numbers that are stored in the phone or using the favs widget and that includes returning a call so the number is already listed. If I hit the number it dials for about a second then says call disconnected. BUT if I manually dial the same number after it drops it will dial out fine. I haven't noticed any rhyme or reason for it doing this. It just seems to happen randomly. Maybe it is linked to low signal? It just seems odd that I can always dial the number after if I type it in. 2) When using GPS naviation (Maps) if I get an incoming call - no problem but if I dial out, after a few seconds on the phone the phone will reboot itself. Anyone else have these issues?
