Summary: Phone is fantastic. Love it completely, had an issue a few months in (Used phone), so I opened it up with my tools and found that it had been opened previously. Could see a little water damage, but it doesn't appear to affect the phone, so its all good. Phone isn't too hard to open either to replace Battery. I actually had to replace the volume rocker, because it got bent, and was stuck in the DOWN position.
Summary: The phone arrived quickly and works great. The battery life is beyond my expectations - so much better than my previous phone. I have yet to be under 30% and most of the time 45-50% at the end of the day!
Pros: - Battery life (once you disable some built-in apps) - Screen contrast
Cons: - Glitchy - Volume is awful if not rooted - Vibrate mode is beyond weak - Built-in apps suck (both to use and power) - Camera's very fickle - doesn't focus very well or quickly - Screen calibration
Summary: I have an extremely poor impression of this phone, after owning it for over a year. It is full of applications and bloatware that are unwanted and unremovable. The bootloader is locked, so I cannot remove this software and install a custom ROM running proper Android. The audio player frequently skips and stutters (around 1 to 6 times per song). The battery life is a strong point. This phone's battery lasts an unbelievably long time, especially for a smartphone.
