I keep my bitcoins on a cell phone that is almost always turned off. I very infrequently turn the phone on, only to transfer coins to the wallet. the last time I received coins apparently was 8+ months ago. I saw a message from the wallet that said I was 8 months behind. This makes the app extremely slow and laggy, to the point that I cannot send/receive at this point. I've tried waiting for the sync, but the phone (galaxy s3) automatically turns off after 10 minutes, the longest setting that I can choose. The wallet also gives me messages that it is not responding, I usually tell it to wait, but I have no idea how long the sync will take. Until then, I am basically stuck with an unusable wallet. Advice?
