Been having issues since I got it at WP8 launch, and have been experiencing things like a SIM reader issue and a crappy battery. Really annoyed at HTCs quality control - these things make the average consumer with no platform loyalty get some creap Droid as a replacement. However, my new 8X has been working better with my battery at 6 hours of heavy use and is at 62%. Seems HTC got overwhelmed at launch and didn't make a quality first batch?
