Several. The biggest one is that my Samsung Galaxy SII no longer recognizes the presence of any blue tooth device whatsoever. I have put three different blue tooth devices next to it, all turned on, and the phonse says there are no blue tooth devices in the vicinity.
Lots of my user preferences disappeared. And some of my contacts or some of their data have disappeared.
I hate ICS. We tried a Samsung Nexus and turned it in for a second Galaxy SII. Now they shoved it down my throat on my SII as well. It is possible to roll back to prior operating system without losing all contact info and apps?
"As for going back to Gingerbread, it is totally possible although as with the above if not researched/done properly it could damage your device.
Any questions, please ask?"
So that's my question. How to go back to Gingerbread? Without losing contacts. I can reload apps with much less effort so that's not as big a deal. I do have a backup but a lot of my contacts don't get backed up I guess, because not Google folks.
