I took the back off (to remove and replace the battery as fp2 was not responding to my turning it on - not sure why not!) This piece of white rubber fell out. Where does it go? I know this has been asked and answered before but I can’t see the answers! I’m even reusing an image from someone’s previous post - thank you! Screenshot_20190114-062454|281x500
Ah ha. Got it. Just after posting. It does slot in to the only place in the opened fp 2 where there is a slot that size. Think I turned it clockwise through 90degrees to see clearly where it went tho.
