I also had scads of issues (some other post) resulting in a re-flash - the last ever as the USB port seems to have borked for data
Anyway, I have an X.
After I saw this post, I added a fingerprint which functioned correctly and works. Seems better actually. Hooray.
Screen response seems OK except the browser is borked for links (see other posts)
Encryption is all OK
Mem! is borked (which I use)
