Hey everyone I'm usually great with alot of support with devices but I'm out if options here. My Samsung S21 Ultra continues to freeze and reset its self randomly I don't understand why and now my Samsung Watch 4 is not receiving any notifications. For the phone I tried restoration, cache system clean, virus scan with Bitdefender, and I even tried a new Sim Card swap no luck. Is anyone else going this the same thing?
Have you tried uninstalling the apps you've added since the purchase of your device? There could be a software conflict causing your device to crash.
If you can backup your device, SAVE ALL YOUR IMPORTANT DOCUMENTS, FILES, PICTURES ETC. Clear the system cache again then perform a factory reset.
Once you've successfully reset your device the first app to install would be Samsung Wear in order to verify your Galaxy Watch 4 is connecting and functioning properly.
Before you install anymore apps (other than those pre-installed) go to Device Care and activate Device Protection then scan your device. If no threats are install one app at a time. If a threat(s) is found follow the suggestions to correct it.
After the installation of an app verify it's performing properly. If the app is not performing properly it may be the cause of a conflict.
It does take some time but through the process of elimination you're thoroughly troubleshooting your device to in order to determine the root cause of the system freezing and resetting.
It may be something as simple as an app or you may have unfortunately received a faulty device. Either way your checking off potential causes while you're keeping your device healthy and free of applications that may pose a risk.
This is a basic way to determine whether you're having a hardware or software conflict. I've rooted every device I've owned up to the Galaxy Note9. When I experienced similar issues this process has successfully restored my devices. There are others may not agree with this and/or may have a different process but this has always worked for me. It may be and tedious and methodical but it has always successfully worked for me.
Hope it helps solves your problems, if not I apologize in advance.
you haven't spoken to Samsung help desk yet?? If not, then I would do so. Normally submitting error report to Samsung Members after issue is seen again would be the proper way of reaching out to Samsung for help, but if the device is unusable at the moment then either chat with them online or call them on another phone.
It's possible a hardware is failing
well at least you found some clues... you can try calling or chatting with a samsung engineer and see if they can think of something. when you call or chat you'll first talk to bunch of techs that aren't all that knowledgeable, so you'll have to be a little patient and ask to speak to someone with more depth of knowledge, an actual engineer.
It's for those log info that you saw that users need to submit error reports, even if you have a partial log file it could be helpful if it succeeded in capturing the necessary info.
I am very sorry to hear your phone freezes and resets in addition to no Watch 4 notifications, and can see how frustrating this is.
