Bought this late last year, so I think that I have familiarized myself enough with your phone to give it a fair review. So, it is written all over the forums that users have had enormous problems since they installed the latest update. I did (thankfully) read me all the red flags and of course refused to allow it to update. So, Android v4.1.2 Honeycomb, and I am on the whole generally satisfied with stability.
The screen is sharp but only 720p, even though the camera is filming in 1080p. I've always been a big fan of refined LED technology; This SAMOLED. The camera since then. Yes, it is insanely good, and - in the rough by far - the best mobile camera I ever had in my possession. Even in low lighting and higher ISO images become really schyssta.
Fast, yes, this is a must for me when I move quickly in cyberspace. Finally, the negative battery. Admittedly, it may have to do with me (as I said) to the mold moves me quickly in cyberspace, but I'm actually quite disappointed with the battery life. I have no apps in the background and draining the battery, but nevertheless, I'm usually down to 10% after a day of work, which in my book feels a bit warped. Good thing you did not update when the public says that the battery gets even worse.
