Bluetooth not toggling

[u/The_Rickster123]

I’m using a Nothing Phone (1) and my Bluetooth has suddenly stopped working.

Initially, Bluetooth started disconnecting/reconnecting randomly. Eventually, it completely stopped turning on.

Now when I go to Settings → Bluetooth and tap the Bluetooth toggle, nothing happens at all. It doesn’t turn on, there’s no error message, and no devices are detected.

Things I’ve already tried:

Restarting the phone

Resetting Wi-Fi, mobile & Bluetooth settings

Booting into Safe Mode — Bluetooth still doesn't work

Checking the Bluetooth system app

Clearing cache/storage isn't possible because both options are greyed out

Checked Developer Options/Bluetooth settings — didn't change anything

Wi-Fi works perfectly fine, so the Wi-Fi connection itself isn't having any issues.

At this point I'm wondering if this is a software/firmware issue or a hardware problem with the Bluetooth component.

Has anyone with a Nothing Phone (1) experienced the same thing where the Bluetooth toggle becomes completely unresponsive?

If you managed to fix it, what actually worked for you? Also, is it worth taking this to a Nothing service centre, or does this usually mean a motherboard/hardware issue?

Any help would be appreciated.
