Reboot Your Device

If checking for updates doesn’t fix the issue, the next step is to try reboot your device. To do this, hold down the power button for several seconds and then select “Reboot” when prompted. If your device has a removable battery, you can also try taking the battery out before putting it back in again and then trying to turn the device on once more.

Charge Your Device

Another potential issue could be that your device’s battery has completely drained, so it won’t turn on. If this is the case, try plugging your device into a charger and leave it to charge for at least 15 minutes. After the charge has been completed, try powering the device on once more.

Factory Reset

If you’ve tried charging your device and it still won’t turn on, the next step is a factory reset. This is a last resort solution and will erase all the data stored on your device, so it’s important to back up any important files before attempting a factory reset. To perform a factory reset, open the Settings app and select “Backup and Reset”, then select “Factory Data Reset” and follow the instructions on screen.

Get Professional Assistance

If none of the above steps have worked, then it’s likely there is a hardware issue with your device that needs to be addressed by a professional technician. You can visit a local service centre or contact Samsung support for assistance with this issue.

Use Safe Mode

If you’re having trouble with specific apps on your device, then you can try running your device in Safe Mode to identify any problems. In Safe Mode, only essential apps are loaded, so any third party applications that may be causing problems can be removed. To enter Safe Mode on the Samsung A12, power off the device then press and hold the Volume Down and Power buttons until the Samsung logo appears.

If your device won’t turn on, then it’s possible there may be an issue with your device’s connectors. Inspect the charging port and headphone jack to make sure they are clean and free of dust or debris. If they are blocked, you can use a paper clip or a similar object to remove the blockage.

Check the Power Button

If the above steps don’t fix the issue, then the power button may be the problem. Check for any physical damage to the button that may be causing it to malfunction. If the button is faulty then you may need to have it repaired or replaced by a professional technician.


These are some of the steps you can take to fix a Samsung A12 that won’t turn on. If none of the above steps have worked, then a hardware issue is likely the cause of the problem and you may need to seek assistance from a professional technician. It’s also important to regularly back up your device data in case of any unforeseen issues.
