A Pixel 5, 4a or 4a (5G) is several years old, so when the screen stops responding properly the likeliest culprits are physical: a tired screen protector, moisture, or a cracked or aged panel, rather than Android itself. Work from cheapest to dearest. Peel off the protector and any case, take off gloves, wipe the glass, and see whether the fault follows one app (then it is the developer's) or shows up everywhere. Dry the phone completely if it has been wet; the Pixel 5 is rated IP68, yet water on the glass still triggers phantom taps. Restart, install what is waiting, and only then think about a screen replacement.

Before you touch a setting
Record this first — changing settings destroys the evidence
- The exact phone and Android version, and whether the fault is in one app or everywhere
- Where on the glass the touch fails
- Whether a protector, case or sticker is fitted
- Any crack, moisture or earlier drop

Exact questions
Common questions
Should I update apps before blaming the screen?+
Yes. An app update can fix touch that fails in one app, and Google's article lists updates among its first checks.
Could a bent frame cause touch faults?+
Yes, a bent or cracked frame can press on the panel. If the screen is lifting, stop using the phone and have it looked at.
Why does touch fail only in the rain?+
Water on the glass makes false touches even on an IP68 phone, so dry the phone before judging it.
Is a line across the display a touch fault?+
Not necessarily; lines and flicker are display faults that a repairer checks when the screen is replaced.
Is the Pixel 5 panel the same as the 4a's?+
No. The Pixel 5 has a 6-inch 1080p OLED at up to 90 Hz, per Wikipedia, and a different panel from the 4a.
Will an update still fix a Pixel 5?+
Wikipedia says the Pixel 5 topped out at Android 14, so check Settings for any last patch but do not expect a new system update.
Can I keep using a cracked Pixel 5?+
Tape the crack, avoid pressure and back up first in case touch fails completely.
