I live in the UK and today I bought the G2. It is running android version 4.2.2 and it is prompting me to download the latest software update (presumably kitkat 4.4). I am a bit fearful of doing the update as I heard that the update has caused huge performance issues including severe battery drain and data connection drop outs. My wife had these exact issues when she bought the S4 last month and downloaded the update. Anyone in the UK who has recently downloaded this new update for the LG G2 who can comment and hopefully re-assure me that it is safe to update?
