If it's on a boot loop, I had the same issue. I've put in a complaint to Samsung. It's a problem since the last update but Samsung don't seem to be taking any notice.

I have this same exact issue. Samsung S22 SM-901B (EUX) and yesterday after updating to the October 1 2024 patch level I went into a constant bootloop.

Problem is, you cannot revert the firmware or downgrade, as the latest binary on this patch is C, it is a brand new binary on this October 1 patch.

I have done a full reset with stock firmware and found the following:

1) It still bootloops after the reset, however after 20~ish times (its random) it will eventually land at the greeting screen asking you for your language, google account and samsung account.

If you get here DO NOT turn on wifi.

I have tested this on 2 different occasions, with wifi turned off for different intervals, first time it was off for 20mins, I then connected to my AP and in less than a minute, once it connected and started data transfer, the phone was back into a boot loop.

The second time after resetting and waiting out further bootloops to get back to the greeting page, i did the setup again and then i waited 2.5 hours with it being completely stable before turning on wifi, and again, within a few seconds it was in a permanent bootloop.

Using a phone without wifi in 2024 is completely useless, this needs to be hotfixed ASAP!!!!!!!!!!!!

@Darrenh1984 , presumably you do not have a schedule for Restart set in Device care and do you have sufficient storage?
Restarts can sometimes be caused by conflicts with 3rd party apps or themes. if there is not an issue in Safe Mode would pinpoint recent third party apps which have been installed. https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/
However clearing the cache partition can help with lags/restarts and is recomended after updates. Follow these steps:
1. Turn off the device.
2. Connect To Computer , other Device or TV USB, Press and hold the Volume Up key and then press and hold the Power key
3. When the Android logo displays, release both keys.
4. Wait until the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight wipe cache partition.
6. Press Power key to select.
7. Press the Volume down key to highlight yes, them and press the Power key to select.
8. When the wipe cache partition is complete, Reboot system now is highlighted.
9. Press the Power key to restart the device.

A Factory Reset would be the next step (hopefully can back up).

However if no resolution see if you send an Error Report,Go to Samsung Members-Support-Send Feedback-lock up/Restarting, include details and be sure to include the system logs.  otherwise would need to get in touch with Samsung by other means or visit a Samsung Service centre/Experence store.

Same issue with mine. I've cleared cache partition, turned off WiFi, Bluetooth and nothing seems to work. I've also sent feedback to Samsung and no update from them after a week

Same here, with WiFi on it goes in boot loops constantly. Send error report but I'm not getting my hopes up at the moment
