Screen suddenly goes darker

[Lau6]

Hi! I would like some help. I left my Xperia Z5 charging and when I tried to use it in the morning. Suddenly all the brightness disappeared, I can see that the phone is on but the brightness is in the minimum. I restarted the phone and it continued in the same way so I deleted everything and installed the software that comes in Sony companion but the problem continues. Do you know if this could be something more than the software?

Hi @Lau6, sorry to hear about your phone.

Based on the troubleshooting you have already done it does sound like it's related to hardware and not software, there is however a few more things that you can try!

First of all, try removing the SIM and/or SD card from your phone start it up as normal again and see if you still experience that the brightness of the phone is very low and you can barely see anything on the screen.

If there is no change, open the cover for the SIM and SD card and you will see a small OFF button. Use the tip of a pen or a similar object, press and hold down the OFF button for a few seconds. When you have received three vibrations, release the button and the phone will power off > start it up again.

Should you experience the same behaviour still, your phone will need to be examined at an authorized service centre. Your Local support team will arrange a repair for you so get in touch with them!

Let me know how it went!
