There are two main reasons why the Galaxy A70 won't turn on. The first possibility is a hardware problem that prevents the system from booting or turning back on.

What to do if the Galaxy A70 won't turn on
There can be many reasons why a Galaxy A70 won't turn on. This guide will walk you through the steps on what needs to be done to identify the cause of the problem.
1) Galaxy A70 won't turn on, check for faulty hardware
One of the most common reasons electronics or phones won't turn on is faulty hardware. Has your Galaxy A70 been dropped or hit by something hard before noticing it won't turn on? If the answer is yes, then it could be a physical malfunction. Software changes cannot be made to repair a physically damaged part.
If not, we recommend that you continue with the troubleshooting steps below to understand where the problem is coming from.
2) Try to recharge the battery
Charge your phone. This is the second thing you want to do in this case. Many Android with this problem usually forget the fact that the phone may have simply run out of power. To check if this is the case, all you need to do is allow the phone to charge for some time.
In this guide, we suggest that you let it charge for at least 30 minutes. Make sure you don't interrupt the charging session by turning your phone back on. If the device turns on properly, be sure to recalibrate the operating system and battery as well with these steps:
- Fully discharge the battery. This means using the device until it turns itself off and the battery level is 0%.
- Charge the phone until it reaches 100%. Make sure you are using the original charging equipment for your device and let it fully charge. Do not unplug the device for at least another two hours and also do not use it while charging.
- After the time has elapsed, disconnect the device.
- Restart the device.
- Use the phone until it runs out completely.
- Repeat steps 1-5.
3) Do the charging accessories work?
If your Galaxy A70 still won't turn on at this point, it's a good idea to check if there's a problem with the charging cable and adapter. You must do this even if there are no obvious signs of damage to the USB cable and adapter.
Try to borrow an original set of Samsung cable and adapter for the Galaxy A70. If that's not possible, you can visit your local Samsung store and try their Galaxy A70 cable and adapter.
4) Does the screen also work?
Another possible reason why your phone may appear to be turned off right now is a damaged screen. If the phone continues to vibrate, beeps sound notifications, or displays an LED light, there may be a problem with the screen.
This usually happens when a device is dropped and the display is shattered. Basically what is happening is that the screen is damaged but the motherboard is still working normally.
However, as the screen is the gateway to the system, you need to resolve this first in order to continue using the device. If the screen doesn't turn on at all, you'll need to send the phone back to Samsung so it can be fixed. If everything is fine, the phone should work normally afterwards.
5) Galaxy A70 won't turn on, check the charging port
Another vital thing you need to do if your Galaxy A70 won't turn on is to visually inspect the charging port. This is the part where it is most exposed to dirt, lint, debris, or foreign objects that users usually don't bother at all.
If there is something in the port that prevents the charging cable from making contact with the connectors, charging your phone may be slow or impossible. If the Samsung Galaxy A70 has run out of battery and there is a problem with the charging port, the root cause of the problem may not be charging.
If you think the charging port is dirty, try cleaning it with a can of compressed air. Do not insert anything inside to avoid damaging the system.
If the port is clear and there is no visible damage, then you want to go ahead and proceed to the next troubleshooting step.
6) Perform a soft reset of Galaxy A70
If the problem recurs, the next thing you can do is perform a soft reset. This should clear the system and possibly eliminate the bug as well. To do this, just hold down the power and volume down buttons for about 10 seconds.
Once the phone has restarted, release the buttons. This is usually effective in eliminating bugs that have developed when a system is left running for some time. We recommend that you restart your Samsung Galaxy A70 using this method at least once a week to reduce the chances of bugs.
For some Galaxy A70s, there may be a slightly different way to come up with the same method. That's how:
- Press and hold the Power + Volume Down buttons for about 10 seconds or until the device turns off. Wait a few seconds for the maintenance boot mode screen to appear.
- From the Maintenance Startup Mode screen, select Normal Startup. You can use the volume buttons to scroll through the available options and the bottom left button (below the volume buttons) to select. Wait up to 90 seconds for the reset to complete.
7) Boot the Galaxy A70 in safe mode
Poorly coded or faulty apps can sometimes interfere with Android and cause problems. If your Galaxy A70 started acting strange or stopped charging after installing a new app, try deleting it and see what happens.
If the problem persists or you can't locate the exact app, restart your device in safe mode. Here's how to do it:
- Press and hold the Power button until the Shut Down window appears, then release.
- Touch and hold Power off until the Safe Mode prompt is displayed, then release.
- To confirm, tap Safe Mode.
- The process can take up to 30 seconds to complete.
- Upon restart, “Safe Mode” appears in the lower left of the main screen.
Remember that third-party apps are disabled in this mode, so what you can use are pre-installed apps. If the touchscreen problem does not appear in safe mode, it means that the problem is due to a bad app.
Uninstall the app you recently installed and see if the problem is resolved. If the problem persists, use the elimination process to identify the rogue app. That's how:
- Boot into Safe Mode.
- Check the problem.
- Once you've confirmed that a third-party app is to blame, you can start uninstalling the apps individually. We recommend starting with the most recent ones you added.
- After uninstalling an app, restart your phone in normal mode and check for the problem.
- If your Samsung Galaxy A70 is still problematic, repeat steps 1-4
