Hi,
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 remove the battery as soon as possible from the phone to minimise further damage.''
Here is a link that shows how to dis-assemble your phone. At about 5:10 minutes into the video the battery has been removed.

Then you need to dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 90%+ to remove all traces of corrosion and water.
Here is a link that in general, describes the process.
You will probably have to replace the battery as it is very hard to recover a battery from 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 possibly work correctly again.
If this process seems too daunting, take your phone to a reputable, professional phone repair service and ask for a quote for a repair. If you decide to do this, do it sooner than later.

@pradeep1_ what have you done about the water damage? First thing you want to do is to stop using your phone ifg you have not resolved the water damage. the longer you continue to use your phone the greater the chance of damaging it further.
