My HTC Sensation KitKat ROM has been very quirky, with some weird behaviour with some apps, most notably with Nike+ Running. I’ve decided to try flashing a different ROM. I tried UnoRom again, but that seemed sooo sluggish - it took a few seconds to even come out of sleep each time I wanted to unlock my phone. So this time, I’ve tried Carbon Rom. So far, so good, I’m restoring my Titanium Backups.
