Screen glitch after water damage
So my partner dropped her phone down the toilet and thous the device now has water damage.
We done the usual, left it a good few days in a warm space in some rice and hey presto it came good other than a screen glitch and draining the battery.
Now I've had a good few iPhone device apart in my time and replaced components but I was looking for suggestions before doing anything with the iPhone 6.
I'm guessing a new battery is a given for the draining problem but any suggests on the glitch?
It appears to happen when the battery is very low or when the device is cold.
