Please Help! After my screen was replaced there is a red colour on it.

This is my cousins phone and after she dropped it and broke the screen she got it replaced at a dodgy shop and they have messed up the repair.

Vibration no longer works

There is a red colour coming through also but not as dead or stuck pixels, as a complete tint replacing another colour nearly?

I'm really confused with this one.

I have done a full reset on this phone and updated software and the problem still persists this is likely a hardware problem but any ideas what I would need to replace for her?

Many thanks!
