I recently helped a friend recover files off of his shattered Samsung Galaxy s5. Having been run over by a car, the screen was black and the touchscreen entirely unresponsive. The volume, power, and home button still worked.
Here are some tips for getting data off Android phones like this one. The goal is to get a screen mirror or valid USB connection going.
If your phone simply needs to be unlocked to use USB, try these:
- Connect a USB OTG cable and use a mouse to enter your pattern code. Hold a pencil to the mouse while trying to find the 9 dots for the pattern. I held the phone in one hand to feel vibrations so I could map out the dots. First drag the mouse all the way to one corner, then slowly move it to where you think the dots are, holding the pencil down. Dots will produce a faint vibration when you click and drag lines between them, just like using the touchscreen. Mark each dot location you find, and enter your pattern.
- If you have a PIN or password, simply plug in a keyboard and type it in, hit enter when done.
- If you have a pattern, but your phone locks you out after to many incorrect tries, use the mouse to click the “enter backup PIN” button in the lower right area of the screen. Then plug in the keyboard and type your code in. Once in, the phone will ask for a new lock screen setup, simply hit the home button to get out of this (or Esc on keyboard). Feel for vibration while typing to get an idea if you’re close to getting in (short vib for each keypress, long vib when incorrect PIN entered).
Here are Android Mouse and Keyboard shortcuts from http://paperlined.org
|Menu||Context Menu key
|Search||hold Context Menu key
|Quick Launch||Windows key + <letter>|
- Alt+Tab — switch between recently-run apps
- Ctrl+Alt+Del — forcible ungraceful reboot
PC mouse equivalents to Android keys
|screen tap||Left click|
Left side button
Try using the volume keys (or inline volume control on a pair of Samsung earbuds), if the ringtone volume increases, you’re in! Try plugging in to a computer to get your files.
If your phone needs more permissions to see it as a drive on a computer, and you have no idea where to click onscreen to allow them, keep reading.
The holy grail of shattered screen use is to get TalkBack turned on. This built in Android feature will speak everything onscreen, and allow easy control with a keyboard using arrow keys and enter.
If the phone is new enough, hold down the home button to active Google Assistant (unless disabled, it is on by default). Say “Open Accessibility Settings”. Use keyboard and navigate to Vision->Talkback. Flip TalkBack switch. Press OK on both popup screens, phone should speak something like “TalkBack on”.
Ideally, practice going through these menus on a second working phone to get a feel for keyboard navigation. When selecting an area to click with the arrow keys, the selection does not cycle back to the top when it hits the bottom of the menu, which is great.
With TalkBack on, navigating settings to turn on developer mode and USB debugging is trivial. To turn on developer mode go to settings->about device. You can access settings by navigation, or open Assistant (hold down home) and say “Open Settings”. Hit “build number” area at least 7 times quickly (use enter key). Now developer mode should be on. Navigate to it (right above “about device”) and turn on USB debugging. When you first turn it on, there will be a popup, click OK. USB debugging is now on!
Download a screen mirror application on your computer. I use the Chrome extension called “Vysor”. With Vysor installed and USB debugging turned on, Vysor should recognize the phone being plugged in. One last step is to click the OK button on the authorization prompt on the phone. This will allow Vysor full access so it can screen mirror and control the phone.
Unfortunately, you can’t use a keyboard to click the button as the phone is connected to the computer! You will need to connect a bluetooth keyboard.
First reconnect your OTG cable and regular keyboard to the phone, navigate to settings->bluetooth, turn it on, and connect your bluetooth keyboard. This should be easy if you have TalkBack turned on! Practice on a working phone.
Now plug the phone back into the computer and wait for Vysor to detect it. Using the bluetooth keyboard hit the right arrow a couple times, then hit enter. Vysor should start mirroring the screen. You can now control the phone on your computer through Vysor!
Have fun getting your files back!
