If your Android phone is not starting up or you just want to restart it without having to go through the power button sequence, there are a few methods you can try. The first option is to hold down the power button for about 10 seconds until the phone turns off. Then, press and hold the power button again until the Android logo appears and the phone starts up. Another option is to use a USB cable to connect your Android phone to another computer. On your computer, open a command prompt (type cmd in Windows search bar) and type adb reboot bootloader. This will restart your Android phone without having to go through the power button sequence. ..
