Hello All, just a newbie to the forum, but I've been playing with my unit for some time and no success in resolving a problem and hopefully you can help! The touch screen stops responding, a mouse plugged into USB works fine, and often after killing all apps and restarting it will work for a while. I find Bluetooth and WiFi cause it to occur more often and also the Google Play Protect stops it working also. I'm getting very frustrated, my seller on Ali has been helpful as possible, I've replaced the physical touch panel, but no change. I've just update the MCU to the latest version I found here: https://4pda.ru/forum/index.php?showtopic=973677 and also tried the Update from Malaysk, but still getting the issue. I have the S32F0_XinRC Unit with 6686 Radio. Thanks!
