In addtion, you can upgrade firmware with OTA if the system version of you is V200624 , but the recovery display is abnormal when you update system, please ignore it and keep waiting.
I noticed some bugs
1 Some flickering when using with TS050 display
2 Video playback (youtube) is rotated and distorted when forcing the apps in landscape mode or rotating the display. Occurs both on TS050 and HDMI displays.
3 Many USB touchscreens do not work
