iPhone 15 Pro Max Screen Not Responding: Practical Guide & Next Steps

② FixUpPhone Expert Analysis

Based on Apple’s published specifications, service fees and force-restart guidance, plus FixUpPhone’s published service information.

Step zero — the alive-versus-dead fork

Do this before any setting. Call the iPhone from another phone; listen for a ring or vibration, and try Siri. If it responds while its screen shows a picture but ignores taps, it is alive — the fault is touch. Work the ladder below. If the display is black and the phone is silent to calls, charging and buttons, it may be off or flat: that is the black-screen path, where power and charging come first. Naming your fork helps any repairer: “rings but won’t respond” and “completely dead” lead to different diagnoses.

Partial or total? Read the pattern

Next, map what still works. Touch dead in one strip, corner or patch — especially near a cracked corner, and since a drop — is the classic pattern of touch-layer damage there; the picture can look perfect while that zone stays dead. A whole screen freezing at once is more often the system hanging: every area stops together. Intermittent touch sits between the two — note when it works; those windows are your backup chance.

Safety first: the lifting, hot screen

One finding cancels the whole ladder. If the screen is lifting from the frame, the phone feels hot, or the body looks pushed up, a swollen battery may be pressing the display from inside. Do not press the screen down, do not keep charging it, and do not mail it — skip every step below and get it assessed in person. Handle cracked glass by the frame; do not keep tapping it to “test” it. Operating temperatures are 0° to 35° C (storage −20° to 45° C); a hot-car phone can misbehave until it cools.

Free step one: case, protector, clean glass, no accessories

Remove the case and peel off the screen protector, then test the bare screen. A lifting, wrongly fitted or wrong-model protector can kill touch, and a tight case can press on the display. Clean and fully dry the glass — a wet screen or wet hands can confuse touch. Disconnect wired accessories, including the charging cable. If touch returns on bare, dry glass, the cause is found: refit a correct protector, or replace the case.

Free step two: force restart — the exact sequence

If the phone is alive but frozen, force restart it. Apple’s published sequence is: quickly press and release Volume Up, quickly press and release Volume Down, then press and hold the Side button until the Apple logo appears — about 10 seconds — releasing only when the logo shows. Use the Side button, not the Action button. A force restart does not erase data. Afterwards, test touch across the whole screen, corners included.

Free step three: charge for 30 minutes

If a flat battery is possible — the phone died suddenly, sat unused, or froze as the battery ran down — connect a known-good cable and adapter and leave it charging for a full 30 minutes. This model fast-charges to 50% in around 30 minutes with a 20W adapter or higher, so half an hour is a real test. Then try the force restart again while connected. If it wakes, let it charge properly before heavy use. Repeated sudden shutdowns are a battery conversation, not a screen one.

Free step four: computer Update — never Restore first

If touch is too unreliable to work on the phone itself, connect it to a computer and choose Update. An update reinstalls the system software, preserves your data, and fixes system faults that freeze touch. Do not choose Restore first: Restore erases the phone. It is considered only after an update has failed, and only once a backup exists. One honest limit: approving a computer connection can need a tap, so if touch never returns, a computer may not help until the screen works.

The honest stop signs for hardware

Stop the ladder and book an assessment when you see any of these: dead zones surviving a force restart; ghost touch — taps or typing by themselves; lines or discoloration with the touch fault; a crack at the site where touch fails; or symptoms starting right after a drop or liquid exposure. Each describes hardware damage, not a setting. The IP68 rating was a laboratory rating when new — resistance is not permanent, and liquid damage is not covered by Apple’s warranty.

The money picture, and the digitizer-only warning

Apple sells this repair as one screen unit: $379 out of warranty, or $29 with AppleCare+ — about 32% of the $1,199 US starting price. If the same drop cracked the textured matte glass back, the combined screen-and-back fee is $499, or $58 with AppleCare+. An independent repair is quoted after assessment: ask any shop quoting a cheap “digitizer-only” fix what part is being fitted, because Apple does not sell the job that way. Apple inspects before confirming its final fee; tax and shipping may apply; authorised providers set their own fees. Launch buyers’ one-year warranty expired in September 2024, so cover today means AppleCare+ or a later purchase date.
