Hello,
My FP2 has been going really well. But unfortunately it stopped charging. Very frustrating, however, I had some success.
I cleaned out the charge point (a lot of fluff came out of there which happens when it lives in your pocket). That helped but then it stopped again.
Next, I took the phone apart, unscrewed the bottom module and give it a clean. Made sure all the screws to all the modules were tight. WIN! Seems to be working.
Follow to the very easy steps to take apart the phone. Take time to appreciate how great it is to be able to take apart and fix something yourself.
Hope this helps others.
