iPhone SE (3rd Generation) Screen unresponsive first thing in the morning

Hi,

For the last few days my iPhone SE (3rd Generation) has been

having problems with the touch screen. Strangely the problem only seems to

occur first thing in the morning – for maybe 5-10 minutes or so the rightmost

edge of the screen is completely unresponsive, however the rest functions as

usual. The problem will randomly get worse and spread to other parts of the

screen, but this isn’t always the case. Strangely the problem tends to resolve

itself after these 5-10 minutes.

Restarting the phone (both by using the volume buttons and holding the power

button and just the power down method) does not resolve the issue.

I am running iOS 18.2.1 and I can confirm that all my apps are up to date. I

have almost 80GB of free space on my phone so I do not believe this would be an

issue.

I can confirm that I have tried cleaning the screen at this makes no difference. The

screen protector and case I am using are the same ones I have been using since

I first got the phone so I don’t see how these could be a problem. The problem

occurs regardless of whether I have had the phone on charge overnight or not,

and whether I charge it wirelessly or via cable does not seem to change

anything. I have also tried signing out of my apple ID and signing back in, but

this has not solved the problem either.

Please find an image attached showing a note where I have scribbled to show the affected

part of the screen.

Any advice or suggestions you could provide would be greatly

appreciated as I have no idea what else I can do to fix this problem and it is very inconvenient.

I look forward to hearing from you soon.
