most likely your phone is dead
this are great suggestions

you may think me completely mad but the suggestions I made to you earlier are your best bet, whater will not be attracted by anything unless it is physically touching the water - in order for the water to be physically touching the rice you need to create an air flow to move it, if you don't create an airflow the water or moisture will remain inside the enclosure of the phone case and circuitry
If you agree with the above continue reading - if you don't then just stop here and forget about it
To create an airflow through the inside of the phone from one side or end to the other without opening it is quite difficult
1. You need moving air (either blown or sucked)
2. you need an entry and exit point that will allow the air to flow and collect the water/moisture and carry it out of the device, heat helps this process as it helps the water to turn to vapour
So I suggested 2x methods of getting an airflow through your phone
1 Hair dryer which has the advantage of providing some heat to aid the water evaporate but is difficult to connect to the phone and actually get a flow going
2. Vacuum cleaner - the opposite of the above - no heat but has a better chance of getting a good airflow going - you are in a hot climate so this would be my preferred method, up close and even taped to the side of the phone to get a good effect and I mean sealed up taped with maybe a little gap
I have worked with hitech electronics all my life, there is very little I don't know - water itself will not damage your phone but powering it on while there is water inside may
A girlfriend of mine spilt a can of coke on my laptop - before I could turn it off it shut down, and would not restart - I dismantled it and removed the motherboard which had obvious stains of sticky brown goo from the coke, I washed it under the tap with luke warm water and fairy liquid then rinced it of with cold water, I then took it to a local tyre place and blew the water off with compressed air
the laptop is still working today 100% and is about 7 years old
If I'd suggested such a thing to anyone they'd have laughted at me - water is used in pcb manufacture
anyway airflow is your friend in this case the more the merryer - and for as long as you can
then do an update repair and see how that goes
it can't mak it any worse
