I've had the Fold 4 for about 2 weeks now and no issues so far.
Battery charges nicely up yo 100% and pixels seems fine on my Under Display Camera.
Like you can see the individual pixels in the area of the Camera, but it's not like a fault or anything on my end.
Hi @Deak79, from what you have described, I would recommend sending an error report through the Samsung Members app so that our team can take a look into the issue remotely.
To send an error report: go into Samsung Members > tap on Get help > scroll down to Error Reports > tap OK on the agreement popup for sending system log data > select the issue category > describe the issue and frequency > tick ‘send system log data’ > tap send in the top right.
Please make sure that you keep Samsung Members open after you send the error report, as it takes some time for log data to send through.
It is recommend that you send these error reports within 3 minutes of the issue occurring to assist in identifying any potential deviations in your device performance.
Once it has been assessed by our team, you will receive a response via the Samsung Members app which can be viewed by clicking the notification bell.
