This often starts suddenly after a small change, like an iOS update, a new screen protector, or using a different charger. Moisture, oil, or dirt on the glass can also block touch without you noticing. Heat can make the phone lag and feel unresponsive. The safest first step is to clean/dry the screen and test without the case or accessories.

It can happen, especially if the phone is finishing background tasks after the update. A restart often helps with temporary glitches. If the issue only happens in one app, it’s more likely an app problem than the screen itself. If it happens on the Home screen too and keeps repeating, it’s worth checking Apple’s guidance and considering service.

If touch improves when you remove the case, unplug accessories, or remove a lifting protector, it points to an external cause. If it only fails in one app, it’s usually software. Hardware becomes more likely if touch fails everywhere, gets worse over time, or follows a drop or liquid exposure. Start with the low-risk comparisons before assuming the screen is broken.

Often, yes — many cases improve with cleaning/drying, removing a problematic case/protector, unplugging accessories, and restarting. Avoid aggressive “fixes” that involve random settings changes or risky cleaning tools. If touch stops working frequently on the Lock screen and Home screen even after safe checks, service may be the safest next step. Having clear notes about when it happens helps a lot.
