Witson Android 10! 2021.07.29 firmware update.

official witson!

Thank you for the firmware update. It works great.

Unfortunately I have another problem, which has not been resolved with the new firmware. I cannot tune in or search for radio stations. The radio doesn't work either.

Do you have any idea what I can do there? What codes are there for the settings? With 8888 can I only adjust the logo?
