If you let the battery completely die, your phone won’t respond at all when you press the Power button. If the problem was caused by a dead battery, it should boot up normally after plugging it in and let it charge for fifteen minutes or so. .

If it doesn’t work at all, try plugging the device in with a different cable and charger. The charger or cable could be broken and preventing an otherwise-good device from charging.

Android can sometimes hard-freeze and refuse to respond. If Android is completely frozen, your device may be powered on and running — but the screen won’t turn on because the operating system is frozen and not responding to button presses.

You’ll need to perform a “hard reset,” also known as a “power cycle,” to fix these types of freezes. This cuts the power to your phone or tablet entirely, forcing it to shut down and boot back up.

You can remove the battery, wait about ten seconds, and then plug the battery back in and boot it up.

If none of them helped. Your last hope is to take it to a local mobile repair shop or find a Vivo mobile service center to let the expert fix it for you.
