This tool will help to fix some (not all) of the causes of "Sync is currently experiencing problems. It will be back shortly." message from Google contacts sync

DISLAIMER: this app is free. No obligation to pay. I will be gratefull for you buying the PRO version to support my work but you can use this app for free - just click "Fix" button. Please email me before posting bad ratings. Also note that I'm unable to fix all possible causes of sync failure.

This app addresses some issues with Google cloud sync. It does not fix any issues with anything else (Facebook, "stopped working" messages, etc.)

If this app does not work for you - it's because there are multiple causes for this error message. I've fixed some of those and I do not commit to fix all of them. If you really need help - try to send logs to me via alogcat or via the app itself.

***IMPORTANT: Always do a full contacts backup before running this application.***

In ad-supported version you will need to run fix every time you see a sync problem. If you buy PRO version you will be able to disable ads and get automatic fixes for all newly added contacts. There is no need to recreate account.
Please note that if your sync was broken for a long time - you may have to manually confirm big amount of deletions during first sync after running this fix. See notification area for details.
