What a day, what a day. My contacts went haywire yesterday - storage for contacts went from 1.2MB to 1.9GB and just about everything on my puny 8GB phone started failing due to lack of space. I tried re-syncing, cleared cache, nothing worked. I removed some apps, deleted pics, restarted in safe mode. My contacts refused to open or display. I purposely keep my contacts in gmail for safekeeping but couldn't access from my phone - my link to my friends was unusable.
Did a LOT of searching, tried numerous fixes, I did finally discover that Google Contact Sync failed every time. All other Google syncs worked fine. Stupid me cleared data from contacts. Tried to restore contacts from sync - total failure. Finally discovered Contact Sync Fix app - thank you app gods!! Apparently some conflict with ICE group being considered a fake group caused the problem, but it didn't rear it's head until I booted to safe mode and then back to regular operation. I think I have it fixed, but am still confirming things are back to normal.
I did loose my call log (I also didn't have any call history in my phone) - thanks Vzn Cloud - when I tried to restore it said it did, but it didn't, and then it showed I had 0 calls instead of 500.
You don't realize how much you depend on the info in your phone until you don't have it or can't get to it. Sheesh.
The only issue with CSF app is that it deletes the ICE contacts. So basically, you have to create another entry for those ICE contacts. IDK if this would befuddle anyone who sees ICE at the top of the list (EMS first responders) and maybe they would look further down the list for another ICE contact.
I did that as well Snn5. I created an actual ICE group with the same group members. So far everything continues to work correctly, and my new ICE group still appears at the top of my list.
This experience has led me to start seriously thinking about upgrading my device from my LG LUCID2 (my beginner smartphone) to something with more storage and a bit more oomph - currently leaning towards the Motorola Droid MAXX for the battery life. Taking in a lot of the feedback from the forums here.
