iPhone Proximity Sensor Not Working

Step 1: Try a Different Cable AND Adapter

Cables fail more often than ports. Borrow a known-good cable from a friend, or grab a spare. Use a different wall adapter too — counterfeit chargers are a common silent killer.

Step 2: Inspect the Charging Port with a Flashlight

Hold the device under a bright light and look directly into the port. You're looking for:

• Gray pocket lint compressed against the back wall (most common)
• Bent or recessed pins (drop damage)
• Green corrosion on the contacts (liquid damage)
• Stuck-on residue from sticky drinks

Step 3: Clean the Port with a Plastic Pick

Power the device OFF first — this prevents short-circuits while you work. Then:

• Insert a plastic precision pick at a slight downward angle
• Work toward the back wall, then drag forward to pull lint OUT (never push deeper)
• Repeat from different angles — port lint is layered
• NEVER use metal — paperclips, needles, or pins will short the contacts

Step 4: Brush + Compressed Air

After picking visible debris, sweep the port with a soft anti-static brush, then short bursts (1 sec) of compressed air from 6 inches away. Keep the can upright to avoid propellant spray.

Step 5: Try Wireless Charging

If the device supports MagSafe/Qi: try wireless charging. If wireless works but wired doesn't, the port is dead — you need replacement (see escalation below). If wireless ALSO doesn't work, the issue is likely the battery or charging IC.

Step 6: Force Restart

Sometimes iOS/iPadOS gets stuck in a charging-block state. Force restart resets the power management chip:

• iPhone 8 and later: press Vol Up, then Vol Down, then hold Side until Apple logo
• iPad with no Home button: same as iPhone 8+
• iPad with Home button: hold Top + Home until Apple logo
