How to fix Galaxy A70 won’t turn on | troubleshoot No Power issue

If your Galaxy A70 is not working and won’t turn on, you’ll need to do a set of troubleshooting steps to determine the cause of the problem. This troubleshooting guide should help you get started.

Galaxy A70 won’t turn on solution #1: Check for bad hardware

Samsung Galaxy devices are generally reliable and would continue to run for years if taken care of. This is the same for previous, older Samsung Galaxy devices and we expect the same for newer models. That said, the very first basic question that we would ask you is this: is it possible that your phone may have suffered hardware damage? There can be a number of ways that your Galaxy A70 may be damaged. Dropping it is one and is a common reason for many hardware troubles. Exposure to water or liquid is another. In some cases, leaving a device inside a hot car or hot environment can cause hardware issues too. If any of these things occurred, you should consider sending the device to Samsung right away if none of the troubleshooting steps below won’t work at all.

Keep in mind, hardware damage can’t be fixed by doing software tweaks. If there’s an obvious sign of hardware damage, or if the phone stopped turning on after a possible hardware damage scenario, there might be little to nothing that you can do to fix it on your own. Still we recommend that you continue with the rest of the troubleshooting below to help you determine whether or not the problem is fixable on your end.

Galaxy A70 won’t turn on solution #2: Charge the device

If there was no immediate incident that may have caused physical damage to the device, then the next troubleshooting step that you must do is to ensure that you top the battery off for at least 30 minutes. Charging this long should be more than enough to add power to the battery and allow it to turn the system back on. Many Android users usually don’t do this but in many instances, charging the device up is enough to resolve the issue.

Lithium-based batteries like the one in your Samsung Galaxy A70 may sometimes drain its power to the point wherein it won’t be able to power up the system again. In some cases, such a situation may even lead to total battery loss causing complete breakdown. However, in most cases, a user simply needs to recharge the battery again to jumpstart it. If you haven’t tried it yet, we suggest that this is your first troubleshooting in this case. Make sure to charge your phone for at least 30 minutes before trying to turn it back on. Do not attempt to restart the phone while it’s still charging to allow more than enough minimum power to be added first. After 30 minutes, you can see if the phone turns back on. If nothing changes after charging for some time, proceed to the next troubleshooting step.

Galaxy A70 won’t turn on solution #3: Confirm charging cable and adapter are working

If your Galaxy A70 still won’t turn on at this point, you have to make sure that the charging accessories (charging cable and adapter) being used are all working. Be sure to use the ones that came with the box. If you’re not using them, try to borrow an original set from someone. If that’s not possible either, try to visit your local Samsung store and try to charge your device in there.

Galaxy A70 won’t turn on solution #4: Check for Black Screen issue

If your Galaxy A7 makes sound notifications, alarm, or vibrates but the screen remains black, it’s not totally dead. Many people usually mistake No Power issue, which is the one we’re trying to address in this post, with Black Screen issue. The latter means that the screen may be damaged and no longer works normally. This can be due to a variety of reasons, though the most common one is when the device is dropped or hit by a hard object. Since the screen is the gateway to the system, it needs to be fixed first so you can continue using your device. If the screen won’t come on at all, you’ll need to send the phone in to Samsung so it can be repaired first. If all is well inside, then your phone should work normally after that.

Galaxy A70 won’t turn on solution #5: Check charging port

One other basic thing that you must do if your Galaxy A70 won’t turn on is to visually inspect the charging port. This is the part where it’s most exposed to dirt, lint, debris, or foreign object that users don’t usually mind at all. If there’s something in the port that blocks the charging cable from making contact with the connectors, charging the phone may be slow or not possible at all. If your Tab S5e has depleted the battery and there’s a problem with the charging port, being unable to charge might be the root cause of the problem.  If you think that the charging port is dirty, try cleaning it with a can of compressed air. Do not stick anything inside to avoid damaging the system.

If the port is clear and there’s no visible damage to it at all, then you want to go ahead and proceed to the next troubleshooting step.

Galaxy A70 won’t turn on solution #6: Do a forced reboot

If the Galaxy A70 still won’t turn on, your next move is to do a soft reset. Doing a soft reset is another way to jumpstart a non-working system. Soft reset means simulating the effects of a battery pull procedure. This type of restart is usually helpful in situation like the one you’re having. To soft reset your Galaxy Tab S5e:

  1. Press and hold the Power and Volume down key for up to 45 seconds.
  2. Wait as the device restarts.

In some Galaxy A70  versions, there may be a slight different way to do the same procedure. Here’s how:

  1. Press and hold the Power and Volume Down buttons until the ‘Maintenance Boot Mode’ screen appears (approx. 10 seconds).
  2. From the ‘Maintenance Boot Mode’ screen, select Normal Boot. Utilize the volume buttons to cycle through the available options and the Power button to select.
  3. Wait for the process to complete. It may take up to 60 seconds.

Galaxy A70 won’t turn on solution #7: Boot to Safe Mode

Another possible reason for the problem may be a bad app. If your Galaxy A70 won’t turn on after adding an app, you should consider deleting the said app and see if that will fix it. However, you’ll have to find a way to turn the phone on first in order to do that. This is where safe mode becomes useful. Safe mode blocks third party apps. If you can successfully restart your Tab S5e to safe mode, that’s a clear indication of a bad app problem. Follow the steps below to boot to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the screen with the device name.
  3. When ‘SAMSUNG’ appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see ‘Safe Mode’.

If your Galaxy Tab S5e wifi works normally on safe mode and you think that you have an app problem, you should investigate further. To identify the culprit, you can use the method of elimination. Here’s how:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your Galaxy A70 is still problematic, repeat steps 1-4.

Galaxy A70 won’t turn on solution #8: Turn on Alternate Boot Modes

If your Galaxy A70 was never dropped before and you’re positive that there’s no hardware issue with it, it’s possible that the problem may be coming from an unknown software bug. Although it’s rare, updates or system-wide changes may sometimes cause severe coding problems that may prevent Android from booting up properly. This can manifest in failing to restart, being stuck in Samsung logo screen, or failing to power back on after turning off. If the cause of the problem is an Android OS glitch, you should still be able to restart the device to other software environments like Recovery Mode or Download Mode. These boot modes are independent of Android and are used by Samsung technicians to diagnose software problems. To check if you have an Android issue, consider booting your device to any of them. If your Tablet boots to Recovery mode, you may be able to fix the problem by wiping the cache partition or doing a factory reset. In Download MOde, the only thing that you can do there is to reflash the software. If you haven’t heard of the term flashing before or if you are not confident to do it yourself, you should seek help from Samsung.

Below are the ways to boot to either Recovery Mode or Download Mode:

How to boot a Galaxy A70 to Recovery Mode

  1. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).

How to boot a Galaxy A70 to Download Mode

  1. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Press and hold the Volume Down key and the Bixby key, then press and hold the Power key.
  3. You’ll know if you’re on Download Mode when you see a screen that says “Downloading….”
  4. Remember, if the screen works in any of these modes, that’s a clear sign that you have an Android OS issue. Be sure to factory reset the device in Recovery Mode to fix it.

Galaxy A70 won’t turn on solution #9: Get help from Samsung

As an end user, there’s only so much that you can do. If your Galaxy A70 still won’t turn on after doing all the suggestions above, you can assume that the cause is probably way deeper. It may be a coding issue or bad hardware. Right now, what you can do is to send the phone in so it can be examined by a Samsung technician.
