My wi-fi is useless, since I uptated to 6.0.2... And the battery as well, 4 hours in standby without apps running... how is that possible?? I thought the 6.1 could solve this, but I still having the same issues. Today I'm going to Movistar to claim my warranty, hopefully I can get a new one.
Myself and 2 friends have 6.0.2 and we're all experiencing problems with wi-fi. Problem with mine is constantly having to type my wifi password in whenever I leave the phone in standby. It did start off with very slow Internet, that's now sorted itself out
