What kind of issues on tethering? I am using a Samsung Galaxy S III, factory openline and didn't root it yet but I've encountered problems with Tethering wherein my iPhone that I use to connect via my SGS 3 via WIFI Tethering wherein the iPhone suddenly cannot connect to my SGS 3 WIFI. WIth the stop and start Tethering on my SGS 3 did not resolve the issue. I only isolated that during this Tethering issue, I just reset my SGS 3 and my iphone4 can connect via Tethering again.
Did you encounter this?
