8 months behind in sync

[wren]

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?

You can always use your prvt keys and import them into any desktop wallet like Bitcoin Core, Multibit, Electrum etc and use your funds.
