Strange noises, songs. Sony Xperia T3

[Excellent1]

Hello. Just the other day, the phone suddenly began to utter different sounds, sometimes occasionally, and sometimes to the end, the device was repeatedly rebooted. These sounds can calmly interrupt the song or video. This is not a notification. Appears suddenly and even with the sound turned off. Very strange. Antivirus check results did not. Please understand my problem. Thank you!

@Excellent

That's rather odd, could you test your device in>>>  safe mode

Even in a safe mode, there are these sounds, and sometimes not complete and with different time intervals ... Maybe this is a glitch in the firmware?

Hi @Excellent, welcome to our forum and I'm sorry to hear about this.

It does sound very strange since there is different sounds being played and not the same one. Do you by any chance have your phone in a case where you also keep your credit card / bus card or similar? If you do, try turning off the NFC function in the phone and see if you still receive these sounds.

To turn NFC off, go to Settings > More > NFC.

Should there be no change after turning off NFC, I would recommend that you perform a software repair using Xperia Companion. This will delete all data stored on the internal storage of your phone and reinstall the latest available software, so creating a backup using Xperia Companion before you start with the repair is advised.

Let us know how it went!

After much research, it was possible to determine what kind of sound. It was one of the songs that I never listened to, a feeling that the phone was jammed. Of the installed applications, the latter was installed about 3 months ago. I did not update anything. Unknown sources are disabled, nfc has never been used.

Hi again and thanks for the update.

I'm sorry for my late reply, I have been out of office due to vacation.

Where you able to resolve this if you for example, removed the song from your phone and then you transferred it again to the internal storage / SD card of your phone? If you haven't tried that, I recommending doing that.

Keep me posted on how it goes!
