Liquid Damage Marker

[Marcus_Hybrid]

Hello dear group members, I would like to ask for your help. Anyone have technical expertise or experience in Galaxy Note 20 Ultra, please help me to rectify this.

What is this red dot marker ?

Is this a liquid damage marker ?

If not, what is this red marker ?

I had done some research and most of the loudspeaker boards picture also shown with a red dot on the board.

Your kind advise and feedback are very important to me as my local vendor says it is a liquid damage marker. Says I need to pay for my own repair expenses for the entire LCD which I had never go anywhere near water or liquid with my phone.

I greatfully express my sincere thank you for your valuable response.

I can't help much but what I know is that what they say about the red dot being a water damage marker could very well be true. Its a kinda paper/sticker that reacts by changing colour when it comes into contact with water.
Imo you can argue with the vendors as the sticker would also react to liquid produced from condensation i.e. when your phone is running hot but you're in a cool surrounding and not necessarily only from direct contact with water.

The red colour is sealing sticker for the foam balls in bottom speaker. There is a blue sticker for the top earpiece speaker too, also to seal the foam balls within the chamber.

The water damage sticker is below the sim tray as pointed by the yellow tool in pic that I screenshot.

You've caught another shameless lying vendor who as per usual wants us users to bear the cost for whatever damages or even manufacturing defects that our phones came with!
It'd be great if @Marcus_Hybrid could post the vendor's Co name or address as a warning to other users.
