If your Infinix Note 12 is stuck on the logo, here are some steps you can try to resolve the issue:

1. *Force Restart:*
- Press and hold the power button for about 10-15 seconds until the phone restarts. Sometimes a force restart can resolve minor software glitches.

2. *Charge the Phone:*
- Connect your phone to a charger and let it charge for at least 30 minutes before attempting to turn it on again. Sometimes, a depleted battery can cause boot issues.

3. *Boot into Recovery Mode:*
- Turn off the phone.
- Press and hold the Volume Up button and the Power button simultaneously until the Infinix logo appears, then release both buttons.
- Use the volume buttons to navigate to "Wipe cache partition" and select it with the power button. After that, select "Reboot system now."

4. *Factory Reset:*
- If the phone still doesn't boot, you might need to perform a factory reset. Note that this will erase all data on the phone.
- Boot into recovery mode as described above.
- Use the volume buttons to navigate to "Wipe data/factory reset" and select it with the power button. Confirm the action.
- Once the reset is complete, select "Reboot system now."

5. *Flash Firmware:*
- If a factory reset doesn't work, you might need to re-flash the firmware. This process is more advanced and can void your warranty. You can find firmware and flashing instructions on forums or the manufacturer's website.

6. *Seek Professional Help:*
- If none of the above steps work, it might be a hardware issue. Contact Infinix customer support or visit a professional technician for further assistance.
