In reply to blackmountainbiker:
Sample size of 1 body here, but within one year I had one of the top dials falling off twice (after fixing it by manufacturer) and the on/off dial didn't work. It just wouldn't turn off! I am not sure what was the deal with the on/off switch, but that other dial was just glued on. The view finder is also easy to lose, but same with Canon.
I wasn't the only with twin dial issues, e.g. this thread:

I did downgrade to used Panasonic GX80 off eBay and it's been a year with no issues so far. Since the body is relatively cheap, I care even less for it. No issues! I think having less moving parts works better... the only annoying part is no way of using remote release shutter without a phone over WiFi.
E-M MK2 has nicer view finder and I prefer the ergonomics of it, but being without a camera three times within the first year didn't really work for me.
