put it inside the water my phone network went off, screen stop touchin

So yes, some phones are advertise water resistant phone but too a degree they still can get water damaged, i work at a repair shop and have gotten many phones claimed to be water proof but they still ended up getting water damage. what most likely happen was that your cellular component on the phone got water damaged and if you tried to charge the phone it couldve shorted it. also the touch screen part, the lcd on the phone could have gotten water damage to it but since the pen works fine im not too sure why touch wouldnt work unless the pen doesnt go off of “touch” but instead is detected some other way.
