Hi @stefanandrei

The phone is dustproof and water-resistant, not waterproof.

This was when it left the factory of course but maybe normal user handling since then, has made it even less water resistant e.g. accidental drops causing small cracks in the case, phone case slightly bent due to being shoved into a pocket or purse etc.

Water-resistant devices can resist the penetration of water, when being accidentally splashed or caught out in the rain etc but not when being submerged into water.

The phone has two internal LDI (liquid damage indicators) that change colour from white to red when they have come into contact with any liquid. Their location is shown at 2:30 minutes and 4:54 minutes into the teardown video of the phone linked below.

If water has entered the phone (as shown by the LDIs) then, most probably water has caused the problem.

The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the phone's operating design and could damage the components. The corrosion starts immediately and is ongoing until it is completely cleaned away

First do not try to charge or to turn on your phone and then remove the battery as soon as possible from the phone to minimize any further damage.

Then you need to dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 99%+ (available at electronics parts stores) to remove all traces of corrosion and water. If possible do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain additives and is not as effective. If you do have to use it check the label to verify the amount of IPA. The higher the percentage of IPA the better

Here is a link that describes the process. Electronics Water Damage

As always with electronics, especially surface mounted pcb be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board. Remove the shields that may be covering some components as the water may have got in under there. The ends of any flex cables and their connectors need to be cleaned as well

Hopefully after you have done all this the phone might possibly work correctly again.

Here is a teardown video that may help

If this process seems too daunting, take your phone to a reputable, professional phone repair service, experienced in liquid damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later.
