Purple bar cross the screen

Hi all, I got my MacBook back on 18th April. And I checked the note from Apple repair center which shows they didn't repair anything due to they didn't reproduce the issues what I have. After that, I went to the official Apple store again to ask to replace the machine on 19th April. They told me they couldn't do anything except send it to repair center to check it out or talk with an apple care advisor. Last hour, I just spoke with Apple care advisor, she asking me to do a sysdiagnose by an Apple software called "data capture," then upload the diagnose result with any videos & pic I have to Apple. She told me the engineer would take a look of all profile I upload to make the next decision.
I don't know how I feel like Apple won't be able to solve my problem. Last, It was getting worse for sure, after first-time screen replacement.

Yes. I think so. As someone who works for the local Apple retailer, it is a complete quality problem. Otherwise, the screen should be protected somehow under electromagnetic. What should I do right now? Keep report it?
 
I just got another phone call from Apple care team. They told me that my laptop is having this issue because of USB C. And they say every laptop with USB C will have the same effect as mine. Otherwise, mine getting wore after replacing the screen because of the different screen having a different tolerance. I'm tired of this problem. I hope anyone can show what their laptop (with USB C) has the same problem as me when the cellphone (LTE connection) close to the screen.
 
Is it reliable? Like every time you hold it close it shows purple lines? I have a 2018 and I can try it out on mine right now.

Yes. Every time but depends on the LTE strength I think. If you have poor network strength, these issues may appear. Or, like Apple said, a different screen having a different tolerance.

I just did it to my macbook and it didn't do that. My phone has dual *SIM* on it. My home has a sprint signal booster and a tmobile signal booster. I will bet you I have more radiation going on in my home than yours.

I think what they're saying is ridiculous.

Yes. I'll try to keep contact them.
 
Similar thing but mine turns out to be the projector cord connecting the display.

Said no thanks to $475 LCD replacement, had plenty of problems with this laptop, it’s time to let it go.
