Hotspot wont turn on after updating A51 to One UI 5(android 13)

[devAldo]

I just updated my Galaxy A51 to android 13 after the update was pushed to my device a few days ago. After the update, I realized I couldn't turn on my hotspot, so I did a network reset, and configured the band to 5gz as it was previously, but the problem persisted still. So I set it to the default 2.4ghz and it will work well. I don't know how to fix this, I was using the hotspot on the 5ghz band on the previous OS with no issues whatsoever. Any suggestions on how I can get this fixed, please?

Try get into recovery mode and do Wipe Cache Partition.

- Power off your phone
- Press and hold vol up and power key until you are in recovery mode
- use vol up and down to navigate
- select Wipe Cache Partition
- press power key to confirm
- click yes
- click reboot system

I just did this. But the problem is still there.

Is your mobile hotspot button grey out? What do you mean by couldn't turn on your hotspot? Can you cannect using 2.4GHz ?

[devAldo]

No, my mobile hotspot button is not greyed out, I can turn it on when I change the configuration to 2.4GHz and it works, I can connect devices to it. But once I change it to 5GHz, the button won't toggle on at all, this was working before I updated to One UI 5(Android 13)

You may need to do a full backup using SmartSwitch and do a factory reset on your phone. Because network reset and wipe cache partition won't help.

So I finally did a factory reset, and guess what? It is still not fixed. i am starting to think it is a bug with the new update. I wiped the cache partition, reset the network, and now factory reset, but the problem is still not solved, I will like to know if anyone else with the same device has this problem after the update.

Thank you Tallman.

I tried all the solutions above, wiped the cache partition, reset the network, and did a factory restore of the phone, and I still can't turn my hotspot on when the band is changed to 5Ghz.
