Found an Issue on my LIT box today - Onscreen keyboard was not displaying. I could only use the "talk" function. Well that did not help...
In Settings/Keyboard, There was no Current Keyboard active, and I had 3 items listed under Manage Keyboards. GBoard was switched off and grayed out, and I could not activate it. Google voice typing was active but grayed out and Virtual Remote keyboard inactive. Switching on Virtual Remote Keyboard activated Google voice typing, which I could turn on and off, but GBoard remained grayed out. Trying the various combinations of the two available did not change anything regarding the no display on screen.
Frustration, Google searches, and looking throughout settings did not find a solution the issue, until I read something on the KODI forums (was getting desperate for a solution before resetting to factory settings as a prelude to turfing the box). Gave it a try and problem was miraculously solved.
Solution -
Go to language settings, and change the language to English (US) (I was on English (UK)). Suddenly GBoard was the Current Keyboard and active, and my on-screen keyboard appeared.
Now I have no idea what caused this issue - It was working fine a few weeks ago, and I don't mess around with settings when things are working. So maybe some of the MyBB boff's can add comment or explanation here.
I trust that this post will help others who find themselves in the same predicament, and won't have to spend 4 hours trying to find a solution.
