I have a Chuwi Hi9 Plus with the original keyboard that i purchased in May 2019 and this problem with the keyboard just started yesterday.
If i try to start up the Hi9+ with the keyboard already attached, the tablet cannot start up, it keeps looping between the Chuwi logo and the Chuwi and Android logo.
If i remove the keyboard and then try to start up the Hi9+ then the tablet starts up completely alright, and works perfectly fine.
After the Hi9+ has started up alright, then i attach the keyboard, when i go to any app to try to TYPE using the keyboard, no text appears when i type on the keyboard (virtual keyboard works fine). And then within 1-3 minutes of the keyboard being connected to the already started up Hi9+, the Hi9+ will reset itself (without me doing anything to ask it to restart) and the tablet will start the looping with the Chuwi Logo and Chuwi and Android logo and will again not be able to start up. During those 1-3 mins i get with the keyboard attached and Hi9+ started up, i have managed to go into the Settings/About/Input/Keyboard and it indicates the Keyboard is not connected.
It appears that the keyboard is faulty. i am unsure if it is hardware or software problem.
I have written an email to firstname.lastname@example.org but I’m not sure if the keyboard is covered under the 1 year warranty and actually whether Chuwi will reply my email, so would just like to check with other users if anyone experienced the same problem and of course, if anyone has managed to solve the problem on their own?
If there is a software reset or reconnection method i could try, i would appreciate any advice on that.
And as a side question, had anyone used the Logitech K480 Bluetooth keyboard with the Hi9 Plus tablet ? Does the Hi9 Plus fit in the K480 slot, i see the dimensions of Hi9 Plus is around 270mm but the slot for K480 is like very slightly under 270mm and it may or may not fit. Also, any comments on how well or not well the K480 works with Hi9 Plus? I am kinda prepared to have to buy another keyboard for my tablet. Appreciate any comments / suggestions on other Bluetooth keyboards that work well with the tablet also.
I will update again if Chuwi replies my email.
