LG G5 touch screen

Hi,

Has the phone been dropped or gotten wet at all?

You may have to get the digitizer replaced or get a complete LCD/digitizer replacement as it may be safer and easier to do.

Here’s a link to the LG G5 guides which may be of some help

In the meantime, connect a USB mouse via an appropriate OTG cable (On the Go) to allow you to navigate through the phone so that you can backup your personal data etc.

Unfortunately if you have a pattern lock this will not work to unlock the phone.

If you have a pin code lock, connect a USB keyboard (again via the OTG) to key in the number and then swap to the mouse. Be sure to change the lock type settings and screen time out settings to make it easier to get into the phone until you have everything. Be aware for some reason (and I don’t know why) not all keyboards will work this way.

Also be aware that the phone will be providing power to the USB device so the battery will discharge more quickly, so fully charge the battery before you start.

Hopefully this is of some help.
