Floating bubble permission for installed apps
Bubbles, widgets and floating windows need the "Display over other apps" permission. The car's screen has no switch for it, so grant it here for the apps already installed.
On the Jaecoo J5, some apps such as Waze, sign-in pages or map apps can close right after opening because WebView is not turned on in the car. This turns WebView on so those apps work normally.
The page does 4 steps for you:
Check the car and install WebView if it is missing.
Get the car ready — the car restarts (1st time).
Turn WebView on — the car restarts (2nd time).
Check that WebView works.
Before you start (takes about 5–10 minutes):
Park the car in P and keep it ON the whole time.
Do not unplug the USB cable or close this page — the car reboots twice and the page reconnects by itself.
After each restart, if the page does not reconnect by itself: open the engineering menu and set ADB Switch to "Open" again, just like during setup (the car may turn it off when it restarts).
Install JaecooApp first. If the car has no WebView yet, the page downloads and installs it right in the first step.
Stopped or closed the page halfway? Reconnect and press Start — the page carries on from where it left off.

Car screen is back but the page is still waiting? Open the engineering menu and set ADB Switch to "Open" again; the page reconnects by itself.
ADB Switch is on again but still not connected? Press "Reconnect manually" and pick the car from the list.
Taking longer than usual — if the car's screen is back, set ADB Switch to "Open" again in the engineering menu, then press "Reconnect manually" if the page still has not reconnected.
