How to troubleshoot Galaxy S8 Plus with Settings that keep crashing

The following procedure may help you fix the problem and you may not have to do all of them. In fact, if it’s a minor glitch, then the first will take care of it. But, if it’s a serious issue brought by an update, you have have to do all of them and ends up resetting your phone. Try to see what works for you…


Force Restart  your phone – it might be just a minor glitch in the system that resulted to this problem. If you haven’t done so, try doing the forced restart by pressing and holding the volume down and power keys together for 10 seconds or more. The phone will reboot normally but its memory would refreshed. After that, open the Settings menu to know if the error would still show up. If it still does, then move on to the next procedure.

Run your phone in safe mode – there are times after a firmware update that some third-party apps will become obsolete and may result to this problem. To rule this possibility out, try running your phone in safe mode to temporarily disable all third-party applications. Then, open Settings to know if the error would still pop up. If the problem is fixed in this mode, it means that there’s an app or two that’s causing this issue. You need to find that app and uninstall it to bring your phone to its normal operation. However, if the problem continues, then it could be an issue with the firmware.

Wipe cache partition – another possibility is that some cache may have been corrupted or became obsolete after the Android 8.0 Oreo was installed. Corrupt cache can also result to firmware and performance issue like this. To address this and to rule this possibility out, you have to run your phone in recovery mode and then wipe the cache partition to delete and replace all system caches. If the issue still continues after this, then reset your phone.

Backup your files and reset your Galaxy S8 Plus – based on experience, a reset will fix this problem but we’re always hesitant to suggest it without exhausting first all possible solutions because you may lose some of your important files and data. Since you’ve already done all possible solutions to no avail, then it’s time to reset your device. Make sure you backup your files and data first as you may not be able to recover them after the reset.
