Hello, I have manually updated to android pie, selected English, all good, after some apps got updated, I tried prime (it works), and then language changed to Korean, I managed to get to the language setting, and changed it to English, nothing happens, English is selected but all remains in Korean, if I return to the language menu, Korean is selected again automatically, any ideas? thanks!
(I already did a factory reset twice and it happens again)
Try disabling or enabling auto change language in HDMI CEC setting and reboot
