SMS and CALL problems after LCD replacement

Hello,

After i replace the LCD of a Samsung Galaxy J3 (2017), the customer tells me that he can receive calls but not SMS anymore. Also apparently it makes a problem with the proximity sensor, he also says his screen turns off whenever he receive a call...

I only heat the corners, remove LCD and fix the new one with the only flex it has. Then i put a double tape frame special for it and i fix both parts… A normal reparation like i did before.

How to fix those problems and what can be the problem pls guys?

It’s really important… Thank you all in advance
