siren noise

[GeorgiaCyp]

I only bought my Note10 a week ago.  Last night, a loud siren noise went off.  I had to switch the phone off for it to stop

@GeorgiaCyp  it could be a lot of things, don't you recognised the sound, don't you choose this sound for notifications ? if the s-pen is too far from the phone, an alarm will sound to warn you so that you do not lose it. It may be this alarm that you heard. On your side, did you found what happened ?

All joined BT device has a sound if you lost the field or connection, good.

Bye and have you a good day.

Also customer could check reverse cronograph and check if it was inserted an alarm automatily by bixby or by voice or manually, but any device emite sound without programation or randoly.

@Cassidy007 , continue with customer if it's necessary, thank all

Nothing was programmed... it did not happen again but really worried since this is a new phone

[RpBP]

Don't worry Mrs. or Mr.  GeorgiaCyp, when we buy a new mobile usually we touch in a few places to set and somaone could insert a programed notification or let a web page with sounds open or or something described above .

If you continue with the problem, do not hesitate to contact us and we will try to help you as well as possible.

Bye and thank for feedback, you can close thread and mark as solution if some information work with you and if you have the misterious sound again and you can check our tips before restart

About motherboard, you can speak with other owners and ask about it here or in other place.

I have a Samsung S8+ and S9+, predecesor of S10+ or Note10+5G, and I have not issues.

Please if you have not enought 5G where you are living, please select 4G LTE as default mode while Providers finish a complete installation of 5G in the World.
