My contacts list works fine after a reboot for a day or two but then starts to get very sluggish to the point of being unusable. Pictures in dialer and contacts will disappear upon opening the list. Sometimes they come back and sometimes they don't. It gets slower and slower until it crashes and tells me "contacts has unexpectedly stopped working." If I reopen contacts after crashing everything works fine again. Clearing the cache does not help. Other apps perform at normal speed. I am on a RAZR maxx HD with JB and I did a factory reset after the update. All syncs are turned off except syncing to google. This is getting very annoying and any help would be appreciated!
