Every time I switch on my phone the sim manager pops up, no apparent settings to change, I click done and back to normal. But why and how to stop it? Or maybe there's a setting I need to to change.
Everything works fine
Solved! Go to Solution.
Can add to this problem, am having the same isssue, the sim card manager keeps opening after boot/reboot.
On the Tweakers forum (Dutch) have found also 2 others who have the same.
@Samsung: How to fix, or bring an update please for this?
I have exactly the same issue on my S20+ and my wife has it in her S20, so it's a universal issue.
Not sure if it is useful info, but we're both on EE.
Ive gotten the tip to send an error report via the Samsung Members app installed on your phone (or re-install)
Do it like this: boot up the phone, and enter the home screen. Then just wait for the Sim card manager to come up, and click ok/ready. Then go directly to the Samsung Members app, and select bottom option Support, then Send Feedback, then select the option Error reports, and enter shortly the mentioned popup of the simcard manager, and send the report. (Im doing this from Dutch, don't 100% know what the english option names are, but this should be enough to find the options)
This way, Samsung is getting the reports of the same issue in an structured manner, and as long as we all send the reports, this would pick up on their radar.
I have the same issue. After restart it takes about 2-3 minutes and the window appears itself:
OK, here is a solution (more workaround, but is works and that's important):
The issue is probably caused by 1 SIM card in slot 1 and SD card in slot 2 (probably also without SD).
Try this: remove the SD card and put any SIM into slot 2 so you have two SIM cards active. Confirm the dialog and restart the phone. The dialog can but not have to appear. Remove the SIM2 and return SD card back.
Now the dialog shoudn't display after reboot (works for me)
I have the basic S20, 4 days old, and yes, exactly the same issue, but not prepared to do factory reset as it will take me a day to get back to normal. Samsung, get this sorted asap
