Could I have some help?

[RaptorJesus]

Basically; accident happened where some guy on a bike drove by and tried yanking my phone out however it fell down the bottom of it got a tiny crack (it doesn't even go over LCD nor damaged any appearance of anything, just literally the glass part cover has a crack) and it stopped responding to touch, the lower half; are there any quick ways to work around until I get it fixed?

Side question: If anyone else had to get it fixed, how much does it cost?

Hi RaptorJesus,

Welcome to the community,

In this case we can only really advise that we contact a service agent for info regarding repair. They would be able to give you a rough idea regarding the price. Use my signature to find the contact details.

I am sorry for the inconvenience.

Use the otg cable plug in a mouse to access your phone.
In the UK your looming at around £130 for a front glass replacement. But as it's been dropped internal damage may increase that price if there is any.
