iPhone 12 mini touchscreen issues

Is anyone else having intermittent touchscreen issues with their iPhone 12 mini where it randomly won’t register touch input?


TLDR: my phone screen stops registering touch input randomly only when inside of a case and also with a screen protector on. With just the case on, the screen is fine, and with just the screen protector on the screen works fine. It’s only when they’re combined that my screen goes all janky.


I got my 12 mini today, went to Bestbuy to pick up a screen protector, installed the screen protector, put the phone in the Silicone MagSafe case and set everything up. Everything seemed fine until I noticed that the touchscreen was not responding like it should to touch input. I noticed that the screen would only act up if I had the case on. When I took the case off the screen was responding exactly as it should so I figured it was an issue with the case. However, my sister had also gotten her iPhone 12 mini today and we tested the MagSafe case on her phone but hers didn’t exhibit the same problem.


At this point I decided to pull the screen protector off and test again with and without the case on, and the touch input issues were gone altogether. So I figured, “okay, maybe I got a bad screen protector,” so I went back to bestbuy, returned what I thought to be a faulty screen protector, purchased a Zagg Invisible Shield screen protector, and had them install it for me. But when I powered my phone back on in the car, the screen still wouldn’t register touch input correctly with the new screen protector while in the MagSafe case. I can still take the case off and the screen works fine, but inside the case with a screen protector on, the screen starts acting up.


Finally, I decided to try a different case altogether. We went to Target and I put on a generic non-MagSafe case and the screen issues returned. I’m not sure why but it seems like the issue only pops up when a case is on the phone while also having a screen protector on. If I take one or the other off everything works perfectly. Does it seem like my device might be faulty?

Check the link that was posted above. I think they’ve narrowed the problem down to a grounding issue. If you touch any part or the metal chassis of the phone, the lock screen touch input starts working normally again.


For now, I’ve found that touching the camera rings while unlocking fixes the problem. It’s not a great solution but at least it’ll get me by before I can get my phone looked at. There’s no way I’m going without a case or screen protector so this will have to do for the time being. I have an appointment to get it looked at tomorrow so I guess we’ll see.


Hopefully this helps someone

I ended up doing a forced shut down of the phone; click volume up, click volume down, then click and hold the right side button. I also read in some forum about simply touching any metal part of the phone case as the problem was thought to be due to static (?).


I had to do the shut down once and it hasn't recurred. I had the latest iOS version when this happened.

Not true! I have the latest update, and it fixed NOTHING! Touch screen totally unreliable.

flipping back to top happens more than it doesn’t.

I keep getting “liquid detected” and can’t use my phone for hours because it won’t charge.

huge waste of money and time. By time, I mean taking it back to get it fixed. It never does get fixed.

We bought two iPhone 12 minis just a little over a month ago. Mine works fine, but my wife’s screen will not respond on a daily bases. iOS is up to date (14.4) She has no case or screen protector. I have done a forced restart. Problem still persists. It will take multiple touches to work, which I have documented on video. Seems to respond better to my touch than hers. We have had multiple iPhones over many years. This is first time she is seeing a problem of screen not reacting to her touch. Makes me wonder if the new ceramic shield decreases touch sensitivity?

Update your phone to IOS 14.4. Updating solved my problem. If you can't update right away hold your finger over the camera while you open the phone from the locked screen. That should work for you until you update the system. Also if you have a case and a screen protector on the phone, remove one or both and it should also solve the problem.

Nobody found that solution helpful. You are advising someone to remove their expensive screen protectors to solve a touchscreen issue and you legit think you're okay to do that! It is reckless advice and doesn't fix the issue which is post 14.4 people are still having sporadic touch issues. Don't comment on matters you can't help or regurgitate advice given back in November when the phones were released. Thanks, chocolate teapot.
