Your Android phone was working as it should. But after shutting it down, you cannot boot it again, no matter how hard you try. And on the rare occasion when you do succeed, it never bypasses the welcome logo.
Why will it not power up? An app, a piece of hardware, or a recent update may be the culprit. But whatever the cause, here’s how to troubleshoot boot problems on Android phones.
Check the Charger
More often than not, your phone fails to boot for lack of power. And as the charger delivers the power, inspect it first. Does it have a loose pin or wire? More importantly, does it emit a burning smell or soot? If so, get another. But if not, test it on another phone as a precaution.
Replace the USB Charging Cable
Don’t throw away the charger after it fails to work with more than one phone. The problem could be its USB charging cable. Although it’s made to be twisted and bent many times, the cable eventually fails after repeated use.
So inspect its bends, the most vulnerable spots, for worn-out insulation and severed wires. Also check the connectors for faults. And if you still can’t spot the problem, replace the cable.
Unclog the USB Port
You realize the charger and USB cable work just fine. So what’s preventing the power from reaching the phone? It’s most likely the USB port. Located at the bottom of the phone, it quickly fills up with dirt and lint. So peek into it and inspect the connectors. Are they clogged up with dirt? If they are, clean them using compressed air because sharp objects damage them.
Inspect the Battery
After giving the charger as well as the USB port and cable a clean bill of health, now turn to the battery. Is it bloated or leaking? Then it’s likely dead and needs to be replaced. But if it bears no visible signs of damage or deterioration, have it checked just in case.
Do a Power Cycle
Does your phone come with a removable battery? Then perform what’s known as a power cycle. Remove the battery for about 15 seconds to disconnect the phone’s power supply. Put the battery back into place and press the power button. The surge of fresh power performs a soft reset, which usually forces the phone to boot.
Check for a Stuck Power Button
Age, frequent use, or an ill-fitting casing, often render the power button ineffective. As a result, it either stops functioning, making it impossible to turn on the phone, or it gets stuck and, therefore, powers down the phone each time you power it up. For this reason, ensure it functions correctly. And while you’re at it, remove the phone casing and reinstall it, in case it’s pressing down on the buttons.
Remove the MicroSD Card
Does your phone have expandable memory? Then the MicroSD card you’ve installed may be behind your booting problems. Like any other plugged-in hardware, the card affects normal phone and app function. So when it malfunctions, so does the phone and any app dependent on it. Fortunately, removing it usually remedies the problem.
Boot in Safe Mode
You’ve tried all the tips listed above, yet your phone remains dead. What do you do next? Press down the volume down and power button or the home and power button simultaneously. After a brief vibration, your phone should boot in safe mode.
In this mode, it loads only core files and not user-installed apps or system updates, which might conflict with your phone’s hardware, causing it not to boot. From the safe mode menu, uninstall the updates, reset the phone, or power up the device.
Check the Screen
After booting the phone normally or in safe mode, you feel the phone vibrating, meaning it’s booting up. But the screen remains blank. What could be the problem? You likely have a damaged or dead screen.
And unfortunately, you cannot repair or replace it yourself. Only an expert android, cellphone and iPhone repair service can do it for you. So contact one and schedule to have your phone repaired.
Have the Phone Repaired
So long as your phone remains responsive, you can boot it up. But if it stays dead after all your efforts, it’s likely hard-bricked. A hardware fault or a catastrophic system fault may be behind the malfunction.
Unfortunately, you cannot revive a hard-bricked phone by yourself. You lack the necessary parts, tools, and expertise. What’s more, you cannot reinstall the phone’s firmware to undo a system failure. Only a repair service can.
Don’t let an unresponsive phone scare you. It may only need a new charger, charging cable, or battery to power up again. Or, you might have to do more and unplug the memory card or reboot in safe mode. But if the screen remains blank, despite your efforts, then have it looked over and repaired by a specialist.
