Unlock Phone with Broken Screen: 6 Ways
If your phone’s screen is broken but still responds to touch, you can unlock it by swiping or entering your PIN blind. If the touchscreen is dead, you’ll need a USB mouse, a keyboard, or a computer with the manufacturer’s unlock software. This article covers six practical ways to get back into a phone with a cracked or non-responsive display, plus what to do if the screen is completely black.
Why a Broken Screen Still Unlocks (Sometimes)
Modern phones have two separate layers: the glass on top and the digitizer underneath that detects touch. A crack in the glass does not always break the digitizer, so the screen may still register taps and swipes even with spiderweb cracks. The display itself (the LCD or OLED panel) can also survive a shattered glass layer, which is why you can often see the lock screen through the damage. The unlock method that works depends entirely on which layers still function.
- Glass cracked, touch works: The phone behaves normally; you just need to see the screen well enough to swipe or enter your PIN.
- Glass cracked, touch dead: The digitizer is broken. You need an external input device.
- Screen black but phone on: The display panel is dead, but the phone may still boot, ring, and respond to USB commands.
Method 1: Swipe and PIN (If Touch Still Works)
If the screen responds to touch, unlocking is straightforward. Wipe the glass clean so your finger glides smoothly, then swipe up from the bottom of the lock screen. If you use a PIN, pattern, or password, you’ll need to enter it blind if the display is too damaged to see. To do this, clean the screen, watch for the haptic vibration when you press a key, and count the positions of the numbers (1–9 on a standard keypad). This is easier with a pattern lock because you can feel the grid points. If you have a fingerprint sensor on the back, side, or under the screen, use that instead—it bypasses the lock screen entirely.
Method 2: USB Mouse or Keyboard (OTG Adapter)
When the touchscreen is dead, a USB On-The-Go (OTG) adapter turns your phone into a mini computer. Plug a USB mouse into the OTG adapter, connect it to your phone’s charging port, and a cursor appears on the screen. You can then click the unlock button, enter your PIN, and navigate the phone. A USB keyboard works similarly—use the Tab key to move between fields and Enter to confirm. This works on virtually all Android phones and on iPhones with a Lightning-to-USB adapter (though iOS support for mouse input requires iOS 13 or later). If the screen is completely black but the phone is on, you can still use a mouse to unlock it and then back up your data before the display dies.
Method 3: Manufacturer Unlock Software
Both major phone makers offer official tools that let you unlock a phone from a computer, provided you have previously enabled USB debugging (Android) or have the right credentials (Apple).
- Samsung Smart Switch: If you have a Samsung, Smart Switch can back up your data and, in some cases, unlock the phone if you have the device password. It requires the phone to be in download mode and may wipe data.
- Apple iTunes/Finder: If you have an iPhone, connecting it to a computer and putting it into recovery mode allows you to restore it. This erases the phone and removes the passcode, but you can restore from a recent backup afterward.
- Google Find My Device: For Android, you can log into google.com/android/find on any computer, select your phone, and choose “Erase Device.� This removes the lock screen, but it also wipes all data.
These tools are the only official ways to unlock a phone without the screen; third-party unlocking services often require the screen to be replaced first.
Method 4: Smart Lock and Biometrics
If you set up Smart Lock (Android) or Face ID (iPhone) before the screen broke, you may not need the screen at all. Smart Lock can keep the phone unlocked when it’s on your body, at a trusted location (like home), or connected to a trusted Bluetooth device. If your phone is already unlocked because of Smart Lock, you can plug it into a computer and access files without entering a PIN. Face ID on iPhones works even with a cracked screen as long as the TrueDepth camera is intact—just look at the phone and swipe up (if touch works) or use a mouse to swipe. Fingerprint sensors are the most reliable because they don’t require the display at all.
Common Problems and What to Do When Nothing Works
Sometimes the phone is completely unresponsive—no vibration, no sound, no LED. That usually means the battery is dead or the phone is off. Charge it for at least 30 minutes, then try again. If the screen is black but the phone vibrates when you plug it in, the display is likely broken but the phone is on. In that case, use a computer to access your files via USB. For Android, you may need to enter your PIN on the computer to allow file access—if you can’t, try the mouse method first. If you have an iPhone, you can use iTunes to back up the phone even with a dead screen, as long as you trust the computer (which you may have done previously). If all else fails, you can take the phone to a repair shop; they can replace the screen, which will restore full functionality. But that costs money, and if you just need your data, the methods above are free.
Costs and Safety Considerations
Replacing a phone screen is the most reliable fix, and prices vary widely depending on the model. A DIY replacement kit for a common Android phone can cost $20–$60, while a professional repair for a flagship phone can be $100–$300. Before you spend anything, try the free methods first. Safety-wise, be careful with broken glass: the edges can be sharp, and small shards can get under your skin. Use a screen protector or clear packing tape to cover the cracks and prevent injury. Also, avoid pressing hard on the screen, as that can worsen the damage. If the screen is black but the phone is warm, it may be overheating—turn it off if possible.
Frequently Asked Questions
Can I unlock my phone if the screen is completely black?
Yes, if the phone is on and you have a USB mouse or keyboard, you can unlock it blind. Alternatively, use manufacturer software from a computer, but that may erase data.
Will a broken screen affect my fingerprint sensor?
Usually not, because the fingerprint sensor is a separate component. If it’s on the back or side, it will work fine. If it’s under the screen, it may fail if the glass is shattered in that area.
How do I back up my data with a broken screen?
If the phone is unlocked, connect it to a computer and copy files. If it’s locked, use the mouse method to unlock it, then back up. For Android, you can also use Google’s cloud backup if you had it enabled. For iPhone, iCloud backup may work if the phone is on Wi-Fi.
Is it safe to use a phone with a cracked screen?
It’s safe as long as you avoid touching the exposed glass and cover it with tape. But if the screen is black, the phone may overheat because the display isn’t dissipating heat properly—turn it off if it gets hot.
Can I unlock a phone with a broken screen using my voice?
If you have Google Assistant or Siri set up to respond to “OK Google� or “Hey Siri,� you can ask it to open settings or make calls, but you cannot unlock the phone with voice alone unless you have a trusted voice match enabled, which is rare and not recommended for security.
