I recently got a wireless GMYLE Universal Aluminum Ultra Slim Bluetooth Keyboard with Trackpad for All Windows Android PC Tablet Smartphone ....my phone and tablet don't seem to care about leaving and returning as all I have to do is switch the keyboard off and both Androids just turn off the keyboard off in settings......
where as Windows 10 when I want to come back to the LT, it shows the paired kb in the Bluetooth settings but will NOT recognize it....I have to remove it and repair the keyboard. I will get a 4.0 USB dongal in the mail today, I'm hoping that will be a fix.....I've tried to refresh system devices....doesn't work....anyone know a work around? I love this keyboard for my phone and tab....even puts a mouse pointer on the screen....really a great keyboard.
