iPhone 8 Keeps Freezing and it's Unresponsive

Question

Had my unresponsive iPhone 8 screen replaced last week... Now I wake up today to the "no service" bug after literally using it not 5 hours prior... I reset network settings, turned airplane mode off and on again, hard reset the phone, took the sim card out... wtf. Should I do a full reset? I feel like that would be redundant seeing that I already did a network reset.
Any help is appreciated.

Update: I just tried my sim card in another iPhone and that iPhone get signal within a few seconds. I tried that iPhone's sim card in my iPhone and still no service.

You may need to try a restore in iTunes. Who did the screen replacement?

Comments

I took my screen to the Apple store. He said when they opened it up that there were one or two screws missing and the water seal for the case was not replaced when the previous owner had the screen repaired.

I erased my iPhone through the Find My iPhone app and it still says "no service." I'm on a shared plan with T-Mobile and everyone else still has service, so it's just my iPhone.

You have a used iPhone 8 already? I find it a little strange for it to already have a previous owner as the phone only came out in October. Do you know if it’s possible it was a stolen device? When Apple opened it, did they refuse to repair the screen? In my experience. If another place replaced the screen, it voids Apples Warranty and they won’t touch it.

Yeah I bought it used. Apple had no issues replacing the screen they even said it was under warranty because it was less than 1 year old. Before I bought I checked the IMEI and when I looked at it I checked to make sure it wasn’t iCloud locked or anything. I’ve had it for about 3 months and so far never had any issues that would lead me to believe it was stolen.

I’m surprised that they still replaced it under warranty if the screen had already been replaced. Unless they verified that the replacement screen in was an Apple part, you normally don’t find missing screws with an Apple repair. If they are still honoring the warranty, I would bring it in. You can try to do a restore in iTunes first though.
