Hi, I'm new to the world of Android but I'm considering upgrading my iPhone to the Galaxy S2. After some Googling I discovered this site and it seems like there's a great community here. I was wondering if the following questions could be answered: 1. I see there's a lot of battery posts. Is there a genuine issue with the battery? (I'm used to charging my iPhone every night so 18 hours of moderate use would be fine). 2. Is there any advice from previous iPhone users about adapting to Android after using iOS? Anything regrets or things you miss? 3. I know some touch screen devices are regarded as laggy and not as smooth as the iPhone. Is the S2 on par with the iPhone's responsiveness and multi-touch? Thanks, I realise these may have been covered in other posts on the forum.
