xz3 camera and flahlight become unavailable after over heated

[MervynYelt]

Sometimes when i open camera, it says 'error,unknown error' and flashlight is unavailable.

Then i find it happens when the  phone is over heating. But I didn't use camera at those time.

To get it back to normal, I have to restart the phone after it cools down.

So is camera and flashlight affected by the temperature even if i don't use them?

I have the same problem, when I open the camera it tells me an unknown error, the Led light does not work ....

Any solution ?

The phone can't overheat, if it gets too hot, it will stop some apps/functions to help cool down the device and prevent any physical damage, if it gets too hot, it will shut down

Same story. Any ideas how to solve ?

Does this only happen when your device gets too hot? if so, then there's nothing you can do about it

It's been more than one week since last time when my camera and flashlight become unavailble, I have no idea when it will be back to normal.

It happens even when phone cold as piece of ice. After hard reset problem not solved. From now on camera is not working at all.

I suggest you run a system repair with the Xperia PC Companion to rule out any software issue.

If this doesn't help it's time to contact your local support to get a repair.

[MaksimS]

Done. But still unknown error with camera.

Just to check:

The battery was charged, you did the software repair, no errors and after that your camera still gives this 'unknown error'.

Question: did you restore the backup?

Fact of the matter is that sometimes 3rd party apps can cause trouble.

If you did restore the backup then I suggest to redo the software repair with Xperia Companion only this time don't restore the backup.

Just install the most needed apps and just mainstream apps from which you can expect that those behave nice.

If you already did so and still have these problems then your device is due for repair.

In that case open the Support app on your device and let that guide you to official Sony repair in your country.
