I have only problems with 2x Z10 Pro and 1x Z10 Pro Max: 1 was fickering during the setup, the other one does not recognise my usb2 drive that I used on more than 50 older formulers, even after restart,but it recognise another flashdrive, even after "repairing my usb stick on the pc, not working, but the other Z10 recognises this USB drive...strange ! Some of them I had to press 3 to 5 times on the RCU to move the cursor, after using another RCU it has solved the problem with all the RCU, all of them work very bad in vocal with the Gboard , and none of them work in vocal with 4 versions of Leankey Keyboard Pro (6.1.19 (the last version), +6.1.17,+6.1.13, +6.0.5 all were working like a charm on the BT Hisilicon Formulers (i.e. Z8, Z8 Pro) where they were recognising all the words in the language chosen in the system (French , Dutch, English) even with the Gboard, Z10 serie is barely working recognising 1 time out of 5 one or maximum 2 words...I tried everything, even disabling Gboard, or the microphone access in Gboard but of course I granted always the microphone access,(and even photos access) to Leankey Keyboard that is 3 times bigger than the Gboard when you enlarge it...but although it seem to hear your voice, it's not writing anything in the search bar, the same with the green key on a channel search.
Is there a trick to make it work ?
I'm with cloudflare's DNS, and in IPV4 and of course I tried 2 different GTV-BT1 paired in BT !
