Hi everyone, my FP1 has the same issues for a few months now:
random reboots, unresponsiveness for seconds or minutes and fast battery draining.
I already replaced the battery last year and the one I have is not bloated.
I also did a hard reset a few weeks ago because of the reboots and the unresponsiveness. I thought that could help. Unfortunately it even seems to be worse especially with the battery problems.
I will check the wakelock thing now and I hope this helps.
