I have the 7+ running iOS 11.1.1. I have keyboard missing bug whenever I connect to my bluetooth (V4.1) Remax RB-S5 earphones. I am unable to access my keyboard in any apps. Have to reset iPhone to get it back. I don't have this problem when I connect to my Jabra Move Wireless bluetooth (V4.0) headphones. Any one else facing this problem currently?
