There are many users, so you can always get someone to support you with any complaint -- that doesn't mean there is merit in it.

Obviously, there is something wrong with your setup. I would list my problems (not here, for yourself) and reflash, including eMMC. Then, before restoring the backup, I would see if the problems still exist. My bet is that they don't. Then I would slowly put my system back together, watching to see if the problems return.
