My HTC EVO 4G LTE sprint, though this thread doesn't list my device, i'm getting the same errors...stock everything, haven't even rooted yet nor have google wallet activated, and getting this error. Funny thing is im also getting errors while using my gmail docs on my PC...slow and laggy. Started thinking it may be a server issue altogether. Then tonight they released Google Drive replacing Google Docs...hmmm maybe that will stop the errors. NOPE. I've got no reason to believe that going back to stock will help as I'm still in stock Rom, not rooted, nada. This is a bug that hopefully will be in an update they are currently working on presently. Trying to remove all gmail accounts and re-adding appears to not help the errors either and if I have to clear my contact sync's well then I will have no contacts as they are all saved through gmail. Workarounds are great, but time consuming and often work on one device and not another. I feel writing google will help kick start some buggy code that needs some doctoring. Let's just keep each other posted and hope there is a solution soon enough because I don't dig errors on a brand new phone.
