Flickering ( refreshing ) of all running apps.
The phenomenon of the Android all-in-one device blinking and refreshing
or restarting regardless of the type off app while booting and running and
closing multiple apps is still serious and has not been improved.
Problem accompanying bug 1 above
The DPI setting of PIP is large. However, when the above problem 1 occurs, the DPI size becomes small,
the app's execution screen becomes small, and the app restarts. This has not been improved since last August.

3.BUG when selecting day / night light switch.
When app synchronization is on, when passing through a tunnel during the day,
the car lights turn on and off, and the apps set on PIP are refreshed and
repeated several times, eventually resulting in an app error and app close screen.

※ The above issues 1₃ are widespread issues in DUDU6 7862 and DUDU7 7870 devices,
and the issues are occurring in all apps, not just the navigation and media apps.
I support the addition of new features to DUDU OS, but isn't the stabilization of the OS more important
We deeply appreciate your development and efforts.
