How to Fix an Android Phone That Won't Turn On

Most “dead” Android phones are not actually dead. Before you panic, force restart it, plug it into a known-good cable and charger for 15 to 30 minutes, and look for a charging icon or any sign the screen is on but black. If none of that helps, boot into safe mode to rule out a rogue app before you assume the hardware has failed.

Force restart it first#

A force restart clears a frozen system without touching your files, and it fixes the majority of “won’t turn on” cases caused by a software crash.

• Any Android phone: press and hold the Power button by itself for up to 30 to 60 seconds. Most phones vibrate or show a logo well before that, but a deeply frozen one can take the full duration.
• Google Pixel: on Pixel 6 and later, hold Power and Volume Up together for a few seconds to bring up the power menu, then tap Restart. If the phone is completely unresponsive, hold the Power button alone for up to 60 seconds until the “G” logo appears, then let go.
• Samsung Galaxy: press and hold the Side key and Volume Down together for more than 7 seconds, up to about 60 seconds. Release when you feel a vibration and the screen turns off or the Samsung logo appears.

A correctly performed force restart does not erase anything.

Charge it and watch for a signal that it’s on#

A drained battery is the single most common reason a phone appears dead. Connect it to the charging cable and adapter it originally shipped with, or another cable and charger you know works on a different device, and leave it alone for 15 to 30 minutes before trying again.

While it charges, check for a charging icon, battery percentage, or LED indicator on the screen or lock screen. If nothing shows up after about 10 minutes:

• Try a different cable and adapter (test that pair on another phone or a lamp/outlet first).
• Check the charging port for lint, dust, or damage.
• Remove the case in case it’s blocking the connection.

If the phone still shows no charging signal at all after swapping cable, adapter, and outlet, treat it as a charging-port or battery hardware issue rather than something you can fix with steps alone.

Check for a screen that’s on but black#

Sometimes the phone is actually running, just with a dead display or backlight. Call the phone from another number after it has had a few minutes to charge. If you hear it ring or feel it vibrate, the phone is on and the problem is the screen, not the power system, in which case it needs a repair rather than a software fix. You can also shine a flashlight at a low angle across the screen in a dark room; faint icons or a lock screen visible under the light point to a backlight failure rather than a fully dead unit.

Boot into safe mode to rule out a bad app#

Safe mode starts the phone with only built-in apps running, which is the fastest way to tell whether a downloaded app is the reason it won’t boot normally.

• If the phone is off — Pixel: press the Power button, and as soon as the boot animation starts, press and hold Volume Down until the animation ends. “Safe mode” appears at the bottom of the screen.
• If the phone is off — Samsung: press and hold the Side key to turn it on, and as soon as the Samsung logo appears, press and hold Volume Down until the phone finishes restarting.
• If the phone turns on normally: open the power menu (Power button, or Power + Volume Up on newer Pixels), then touch and hold the Power off or Restart option until a prompt to reboot into safe mode appears, and confirm it.

If the phone behaves normally in safe mode, uninstall whatever app you installed most recently, then exit safe mode with a normal restart to test again.

Symptom, likely cause, and what to try#

Symptom	Likely cause	What to do
No lights, no vibration, completely unresponsive	Fully drained battery or bad cable/charger	Charge 15-30 min with a different cable and adapter, then try Power alone
Charging icon never appears after 10+ minutes	Faulty cable, adapter, outlet, or a dirty port	Swap cable and adapter, check the port for debris, test a different outlet
Screen stays black but phone rings or vibrates when called	Display or backlight failure	Treat it as a hardware repair, not a software fix
Stuck on the logo or restarts in a loop	Software crash or failed update	Force restart; if it keeps looping, boot into safe mode
Works fine in safe mode, crashes normally	Third-party app conflict	Uninstall recently installed apps, then exit safe mode
Turns on, then shuts off again within seconds	Battery health issue or overheating	Let it cool, charge unplugged from any case, back up data soon

When to stop troubleshooting#

If the phone shows no response at all after a full charge cycle, a screen check, and safe mode, or if it was dropped, cracked, or got wet, further button combinations are unlikely to help. Back up what you can if the phone does boot at all — see our guide on how to back up your Android phone — before you try anything more drastic like a factory reset. For Samsung devices specifically, our Galaxy factory reset guide covers the recovery-mode option when the phone won’t respond to normal settings, and our general Android factory reset guide covers the cross-brand version. Past that point, a repair center or your carrier’s support line can diagnose battery, charging-port, and display faults that no amount of button-holding will fix.

Work through the steps in order — force restart, charge, check the screen, then safe mode — and note what changes at each stage. That sequence is what a repair technician checks first, and it catches the software and charging causes that account for most phones that seem dead but aren’t.
