In those moments the display doesn’t work anymore. If I manage to close the graphic, the flickering stops and the phone works normal again.
The Problem first appeared last summer. After an update it was fine for a few month. But now it is getting worse.
I’m using Android 10
It happens on every app that shows (complex) graphics. Like google Photos, Chrome, Whatsapp (If someone sends a video or photo), google maps (only in the “satellite” mode). It also happens on the camera sometimes.
I do use a SD Card and I had some issues with it before. My camera is saying, there wouldn’t be enough space on the card to take new photos. But on the settings it says the card is only about 50% full. I’m not sure, what the card is formatted, I guess it is internal
If the SD card is formatted as internal that could well be the problem. Try and copy all personal data, photos etc. to another cource, a cloud or better a PC.
When you check the Settings > Storage if the SD card is Portable you will see an eject icon to the right.
Formatting as internal means data on there is encrypted so you cannot retrieve it in another device. Whereras formatted as Portable/External removes lots of potential problems and means you can access the contents elsewhere.
