Heyo! Recently I upgraded from 6S Plus to XS. After a weekend out hiking, I used my 6S+ that weekend, I returned to my XS. It stood on in flight mode that weekend. Took it in my hand, face recognition didn't work and the vibrate was as crappy as in the title. stories I unlocked it with my passcode and tried vibrations in the sound settings. Same issue. After a restart, which took longer than usual, everything was working fine again. Has anyone had that issue or heard of it before? Thank you and sorry for my English!
