If your Redmi 12 is stuck on the logo screen, you can try a few troubleshooting steps:
1. **Restart the Phone**: Press and hold the power button until the phone restarts. Sometimes, a simple reboot can fix the issue.
2. **Boot into Recovery Mode**: Depending on the model, you can usually do this by pressing and holding a combination of buttons (often power button + volume down button) when turning on the phone. From there, you may be able to clear the cache or perform a factory reset.
3. **Remove the Battery (if possible)**: If your phone has a removable battery, you can try removing it for a few minutes and then reinserting it. This can sometimes help reset the device.
4. **Connect to a Computer**: If you have access to a computer, try connecting your phone via USB and see if it's recognized. You may be able to access the device's storage and backup important data before attempting any further troubleshooting steps.
5. **Contact Support**: If none of the above steps work, it's possible there may be a hardware issue or a more complex software problem. In this case, reaching out to Redmi customer support or visiting a service center may be necessary.
