Selected SD card by your key input — why this error occurs

If you see a message on your smartphone with the problem "Selected SD card by your key input", it means that your device has an error. This error could happen by accident, by dropping the phone, or by pressing combinations of keys, which led to the problem.

Sometimes your SD card isn’t working correctly on Samsung even if you don't have an SD card in your smartphone. It could be due to outdated software or internal technical glitches in your smartphone. Sometimes a software update helps with this problem, and sometimes it doesn't. This is individual for each user. It can also be caused by breakdowns inside your device. It will be difficult to cope with them on your own, and you will need to contact technical experts who will find the breakage and fix it.
