Hi there! I currently have the Galaxy Nexus phone and i'm looking to replace it with a new-ish phone. I heard about the quad-core Optimus 4X HD but after reading the reviews and videos online i have some questions especially: 1. Very bad autofocus on camera 2. Lags galore when playing graphics-intensive games (which you would expect a quad-core phone can handle) 3. Wifi issues - when held in a specific way 4. Very poor speaker output and/or audio output quality 5. Poor battery life even though its 2150mAh Has these issues been addressed lately with some software updates from LG/Google? Still no word on a Jelly Bean update? Please advice. Thanks.
