Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteUSB debugging must be enabled on the Android phone itself in Settings > Developer options; a computer cannot normally switch it on for you. If the screen is visible but touch is broken, a mouse may help you reach the setting. If the display is unreadable, recovery depends on the phone model and whether it supports an external display. Android also requires you to unlock the phone and approve the computer’s RSA key prompt before ADB can run.
Can you turn on USB debugging from a computer?
Usually, no. USB debugging is an on-device setting. Android’s documented route is to enable it in Developer options, then authorize the connected computer on the phone. On Android 4.2.2 (API 17) and later, ADB requires the phone to be unlocked and the user to accept an RSA key dialog for that computer. Android explains that this prevents ADB commands from running unless someone can unlock the device and acknowledge the prompt (Android Debug Bridge (adb)).
If USB debugging was off and you cannot operate the phone, plugging it into a PC does not provide a supported computer-only way to enable it. ADB commands cannot enable the setting or bypass the authorization prompt.
Choose a recovery route based on what is broken
| Phone condition | What to try | Important limitation |
|---|---|---|
| Display and touch both work | Enable USB debugging through Settings, then connect and authorize the computer. | You still need to unlock the phone and accept the RSA prompt. |
| Display works, touch does not | Try a USB OTG adapter and a wired mouse, if the phone supports USB host/input. | The screen must remain visible so you can see and respond to the UI and prompts. Compatibility varies by model. |
| Display is unreadable or broken | Check whether your exact phone supports video output to an external display. Samsung documents a hub-and-display workflow for eligible Galaxy devices. | This is not a universal Android feature; the phone must support external display, and you must still be able to unlock and operate it. |
| No usable display or input, or phone cannot be unlocked | Seek model-specific repair or qualified recovery assistance. | Android’s authorization flow does not provide a supported way to approve ADB from the computer alone. |
If the display works but touch is broken
A USB OTG adapter can let some Android phones accept a mouse. Samsung, for example, says some Galaxy phones can connect a mouse through an OTG USB connector (Samsung support: using a mouse with a Galaxy phone). If compatible, connect the mouse, use the pointer to unlock the phone, and follow the on-screen steps below.

- 【Strong Adsorption】The inspiration of the silicone phone suction case comes from the adhesive force of the octopus. Each suction cup phone mount is 3.15 inches long and 2.17 inches wide, with 24 independent suction cups providing a stronger and more stable suction force, so you don't have to worry about your phone falling during use.
- 【Back of Phone Suction Grip】Remove the adhesive film on the phone suction cup and stick it on the phone case. You can then fix the phone on any smooth surface, which is very convenient. (The phone suction cup cannot be removed and reused after being attached to the phone case. It is recommended to attach it to a regular phone case, not a valuable one.)
- 【Widely Used】Our non-slip silicone phone sticky grip mount attaches to almost any flat phone case and make it compatible with common mobile phones such as iPhone and Android.You can shoot, watch videos or video calls in the kitchen, gym, dance studio, bathroom and other places.
- 【Capture the Wonderful Picture】Whether you are a TikTok creator or just like to share videos and photos, this phone suction cup can help you hands-free capture wonderful videos and photos for sharing with friends.
- 【Note】You can fix the phone suction cup on a smooth surface such as a mirror or glass. If necessary, wipe the suction cup with a damp cloth to obtain stronger suction. Before releasing your hand, make sure the phone is firmly fixed. (Not applicable to rough walls, wooden surfaces, and other uneven surfaces)
An OTG adapter and mouse provide input; they do not turn on USB debugging or approve ADB access automatically. You must be able to see the display to navigate menus and accept any security prompt. Check your phone’s model specifications or manufacturer support before buying an adapter.
If the display is unreadable
Some phones can send video to an external monitor, but USB-C alone does not guarantee that feature. Samsung documents a recovery workflow using a USB-C/HDMI hub, external display, mouse, and keyboard for supported Galaxy devices running Android 12 or later that support DeX/external display (Samsung support: connecting a Galaxy phone to an external display). Confirm that your exact model meets those requirements before purchasing a hub.

- SUPERIOR COMFORT — Unlike traditional circular ear buds, the design of EarPods is defined by the geometry of the ear. Which makes them more comfortable for more people than any other ear bud–style headphones.
- HIGH-QUALITY AUDIO — The speakers inside EarPods have been engineered to maximize sound output and minimize sound loss, which means you get high-quality audio.
- BUILT-IN REMOTE — EarPods with USB-C plug also include a built-in remote that lets you adjust the volume, control the playback of music and video, and answer or end calls with a pinch of the cord.
- COMPATIBILITY — Works with all devices that have a USB-C port.
- INTEGRATED MICROPHONE — A built-in microphone precisely captures your voice while you’re on the phone, taking a FaceTime call, or summoning Siri — so you’re always heard loud and clear.
If the phone cannot display its interface elsewhere, or you cannot unlock it, an accessory will not make the ADB authorization prompt available. Consider repair or qualified data-recovery assistance rather than relying on a supposed security bypass.
Enable USB debugging when you can operate the phone
- Find Build number. On a Pixel, Android documents the path Settings > About phone > Build number. Other manufacturers may place it elsewhere. See Android’s Developer options setup guide.
- Unlock developer options. Tap Build number seven times. Enter your PIN or password if prompted.
- Open Developer options. Return to Settings and find Developer options. On Android 9 and later, it is commonly under Settings > System > Advanced > Developer options, though menu labels and locations vary by manufacturer and Android version.
- Turn on USB debugging. Enable the USB debugging switch in Developer options.
- Connect and authorize the computer. Use a data-capable USB cable, unlock the phone, and accept the RSA key prompt for that computer. Then check that the device appears in the computer’s ADB device list. Android’s guide notes that version and manufacturer differences can change the menu path.
Can wireless debugging get around a broken screen?
Not for initial setup. On Android 11 and later, wireless debugging requires you to enable the feature on the phone and approve pairing with the workstation over the same Wi-Fi network. On Android 10 and lower, Android documents making an initial USB connection before switching ADB to Wi-Fi (Android’s ADB wireless debugging instructions). Wireless debugging can help if it was already configured and paired while the phone was accessible; it is not a general way to set up ADB on a phone you cannot operate.

Check compatibility before buying an adapter or hub
- For touch failure with a visible screen, verify that the phone supports USB OTG/host input and that the adapter works with its port.
- For an unreadable display, verify video output and external-display support for the exact model. Samsung’s documented workflow applies only to eligible Galaxy devices running Android 12 or later with DeX/external display support.
- Confirm you can unlock the phone and interact with its display or external interface. A mouse, keyboard, or hub does not enable debugging or accept the RSA prompt on your behalf.
- If USB debugging was not already enabled and the phone cannot be operated, plan for repair or qualified recovery help rather than a computer-only ADB workaround.
