Hi,
You may be lucky, but you won’t know until the phone has been opened up and inspected for any water damage. Hopefully you got it out before too much water entered the phone.
As you know water and electronics and electricity are not a good mix.
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.
First do not turn on your phone and then you need to with the phone turned off, remove the battery as soon as possible from the phone to minimize further damage.''
Then you need to dis-assemble the rest of the phone and to inspect the phone and clean any of the affected parts using Isopropyl Alcohol 90%+ (available from most pharmacies) to remove all traces of corrosion and water. Do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain scents and is not as effective. If you do, check the label to verify the amount of IPA.
Here is a link that describes the process.
Electronics Water Damage
As always with electronics, especially surface mounted PCBs be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board.
Hopefully after you have done all this the phone might continue to work correctly.
Here is a link to a video which shows how to replace the touchscreen on your phone. It is handy as it shows to dis-assemble the phone, although unfortunately it doesn’t show how to remove the back cover, so that it can be inspected for any damage.
If this process seems too daunting, take your phone to a reputable, professional phone repair service experienced in water damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later.
You could try an “authorized” Huawei phone repair centre. At least if they mess up your phone you could take it up with Huawei if the repair centre refuses to rectify their mistakes. Just a thought.
