Why don't my screen work when I tap it
my phone got wet but it did not stop that very second when i got in the house i was watching netflix and then my screen would not let me tap anything but every button still worked the same
It seems as though the digitizer (touchscreen) has failed, possibly due to the phone getting wet.
You phone may have a degree of water resistance but that doen’t mean that it is waterproof.
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.
If you wish to access the phone to get your personal data (which hasn’t been backed up to the cloud etc) before the phone may possibly fail even more, try using a USB mouse connected to the phone via an OTG cable -example only to navigate through the phone.
Be aware that the phone’s battery will be supplying the power for the mouse, so it will discharge more quickly.
If you need to enter a pin number to gain access, try connecting a USB keyboard via the OTG cable to enter the pin and then switch to the mouse. Also not all USB keyboards will work this way. I don’t know why.
If you have a pattern lock then unfortunately the OTG cable option will not work to gain access.
After you have retrieved your data (if possible), do not turn on your phone again and then 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 clean all the affected parts using Isopropyl Alcohol 90%+ (available at electronics parts stores) 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.
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.
Here is a link to the ifixit guide(s) for repairing your phone.
If you wish to replace the digitzer yourself, it may be easier to replace the entire LCD screen/digitizer assembly, as the digitizer is glued onto the screen and you may damage the screen trying to remove the old digitizer.
Replacement LCD/digitizer assemblies are available online. Just search for LG X Power LCD screen digitizer part to get results for suppliers of the part.
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 as the phone isn’t going to get any better by itself and may get worse.
