iPhone 12 mini touchscreen issues

I found a solution because it seems to be an conduction issues, so take piece of foil flatten it slide it in phone case under where the phone would be at the bottom or where you finger would usually touch phone. Fold foil on outside of case and touch it as you touch phone and it should work fine

I was also facing the same issue on the first day when I bought the phone. So, I also got afraid and frustrated. But someone told me to update the phone software. So, I did it, and yeah, the issue got resolved. So, basically issue is not in phone, it was in preinstalled software in iphone 12 mini.

just installed 14.2.1 and the mini works perfectly 😊

You can install new Software update 14.2.1, it will resolve the issue.

I'm having the same issue with my iPhone mini, but I was in the store when we noticed it. We went through every case and every different type of screen protector they had and same issue. Other customers that were purchasing the mini also had the same issues. It works fine without the case and just the screen protector, or visa versa. I'm not sure, but I believe because the new protectors go all the way to the edges that perhaps when the case is on, it's every so slightly lifting the edges of the screen protector causing issues with the touch? I'm going to try to find a protector that doesn't go to the edges.

Agreed. After doing a lot of testing it is a grounding issue. Why it works during certain times and not others is bizarre but most relate to the circuitry and when using certain components on the board vs not makes a difference. This does not bode well since that is a serious flaw. The only way they would know is if enough people are putting their claims in through customer service and order a replacement unit. If everyone is just sitting around waiting that’s not giving Apple incentive to do something about it. EVERYONE here should be reporting it and requesting a replacement.

After spending the last two and a half hours talking to apple the only way they can get my iPhone 12 mini to work is without the Belkin screen protection on they have offered to replace it free of charge but not willing to accept any scratches to the screen while I a wait the replacement but that won’t resolve the problem if the same thing happens with the replacement protector but amazingly they don’t accept that screen protector’s don’t work on a iPhone mini be interesting to see if the same problems still happen with the replacement

I also have a brand new iPhone 12 mini 128GB. Experiencing the EXACT same issues with with the Lock Screen flashlight, camera; randomly it won't register my touch for the passcode unlock, and hanging up phone calls, swiping phone to answer phone calls, swiping to power off..I also use the apple branded mag safe case (silicone though), also running latest update iOS 14.2 (18B92) as well. It does have a Belkin ultra glass screen protector on it and I have not tried it without as it was a $40 screen protector. But it sounds like its an iPhone issue and not Belkin. For the first time I tried operating it with the case off and it does seem to be MORE responsive with the apple mag safe case off. The flashlight and camera are a haptic press and do require a bit more pressure but it works much better with the apple branded case removed. Also to note, the silicone apple branded cases as silicone buttons, not metal like the leather. Glad to know I am not going crazy. Did not have any issues when plugged into the apple fast charger via USB-C (I do not have the mag safe charger). Spoke with apple care and they are acknowledging it as an active issue, no known solutions or work arounds.

Iphone 12 mini with MagSafe silicon case and a glass screen protector...

I have just removed the glass screen saver and replaced it by a non-glass film-screen protector (by Olixar) and, BOOM!!, problems have gone!!

I experienced the same problem with two different cases and screen protector. Last night I removed the screen protector and the Lock Screen problem went away. I tried both cases with NO screen protector and the phone works normally. I will continue with no screen protector until Apple has a fix.

This is exactly what is happening to my iPhone 12 Mini. When I have incoming calls I can't move the slide. Now, after I removed the case the slide works easily. I also have a Zagg screen protector on. I also found that if you press hard while opening the slider it will respond but you have to use a bit of pressure. I just tested the touching the 2 rings of the camera while I called myself on another phone and the slide worked just fine. So I believe this is a grounding issue like one of the posts suggested. Without the case the phone grounds thru your hands to the floor. When the case is on and there is a screen protector the phone seems to be ungrounded.

You don't have to do that. Just put your finger on the metal part of the camera when you open it from the locked screen. Or. update to 14.2 or 14.3. Updating fixed my phone and now it's the best phone I ever owned.

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.

I contacted Apple Support about the problem. What worked for me was resetting the settings back to factory settings.

Make sure you're updated to 14.4.1. Updating solved it for me.
