Phone Won't Turn On or Has a Black Screen — What to Do

A phone that won't power on or shows nothing but a black screen is alarming — but in most cases it's not dead. These steps cover both iPhone and Android and will get most phones back on.

  5. Step 5— Recovery Mode (Last Resort Before Repair)

A completely black screen doesn't always mean hardware failure. More often, the phone has a flat battery, has frozen mid-session, or is stuck in a boot loop. Work through these checks before assuming the worst.

Step 1 — Charge It First

Plug the phone into a charger you know works (try a different cable and wall adapter if you have one). Leave it for at least 15–20 minutes before pressing any buttons. A deeply discharged battery won't show any response for several minutes. Look for a low-battery icon on screen — that confirms power is flowing.

Step 2 — Force Restart

A force restart reboots the phone without erasing anything. The method depends on your device:

iPhone 8 and later (including all iPhone 15 and 16 models)

  1. Quickly press and release the Volume Up button.
  2. Quickly press and release the Volume Down button.
  3. Press and hold the Side button until the Apple logo appears, then release.

iPhone 7 / 7 Plus

  1. Press and hold Volume Down and the Sleep/Wake button together for at least 10 seconds until the Apple logo appears.

Samsung Galaxy (most models)

  1. Press and hold the Power button and Volume Down together for 7–10 seconds until the screen flashes or a menu appears.

Google Pixel

  1. Press and hold the Power button for at least 30 seconds. On Pixel 6 and later, press Power and Volume Down together for 10 seconds.

Step 3 — Check the Screen, Not Just the Phone

Sometimes the phone is actually on but the screen backlight has failed. In a dark room, shine a torch at the screen at an angle and look for a faint image. If you can see content, the problem is the display — not the phone's software.

Step 4 — Try a Different Charger and Cable

USB-C and Lightning cables develop internal faults that aren't visible. Try a different cable, a different wall adapter, and a different power socket. Avoid USB ports on computers for this test — they deliver less power and charge more slowly.

Step 5— Recovery Mode (Last Resort Before Repair)

If the phone still won't start after charging and a force restart, connecting it to a computer and entering recovery mode lets you reinstall the operating system. On iPhone, follow Apple's recovery mode guide. On Android, the button combination varies by manufacturer — search for your exact model name plus "recovery mode."

If none of these steps help, the phone likely needs a hardware repair. Ask us and we can suggest your best options.

Frequently asked questions

My phone shows a black screen but I can hear notifications. Is the screen broken?

Most likely yes — the phone itself is running fine but the display has failed (either the backlight or the screen panel). Try the torch test described above to confirm. A screen replacement is usually available from the manufacturer's repair service or a reputable third-party repair shop, and it's often less expensive than a replacement phone.

My iPhone shows the Apple logo and then goes black over and over. What does that mean?

This is a boot loop, and it usually means a software fault rather than hardware damage. Connect your iPhone to a computer with iTunes (Windows) or Finder (Mac), put it into recovery mode using the button sequence above, and choose 'Update' rather than 'Restore' first — Update attempts to reinstall iOS without erasing your data.
