yup, I've got same problem as well. Are u guys using bold 9900?and all chat histories are gone after runing out of the battery and remove it. Dont know is any solution for it ?
我的9900也有一樣問題只要選擇存檔media card就會出現這行字只好選擇device...真的很奇怪捏==剛剛上crackberry看了一下很多人都有同樣問題似乎WhatsApp在OS7裡運作有bug不過有人教了個方法有用,我剛剛也試了1. WhatsApp Settings > turn chat history off2. 接下來進入 Media Card > databases > Whatsapp 裡面有個檔案叫"messageStore.db-journal",把它刪掉3. 回到WhatsApp Settings > turn chat history back on media card試試看囉
