I have had my garminfone for about a year in jan. For some reason I keep getting the icon that says low battery even when there is at least half space free. All t mobile tells me to do is master clear which suck since I have to redonwload all my apps. Which brings me to my next issure for example g reader, and groupon apps that I used to have on the phone before the clear will now not install stating it incompatobile any ideas why?
