Process of Fixing A Galaxy S9 “DQA Keeps Stopping” Bug:

It has been since the previous year when Galaxy users get the bug “DQA keeps stopping.” Although the company released a patch, GalaxyS8 and GalaxyS9 users face the problem even after a few months.

The app lets you know in which way a device uses Wi-Fi for doing tasks. Many of us believe that this bug is an operating system bug. We hope that you will find the methods practical that we have discussed below.

Solutions For The “DQA Keeps Stopping” Bug:

Refresh The Cache Partition:

A few people informed that they fix the bug problem after wiping the cache partition. Therefore, you need to do this thing first. However, indeed, we don’t know whether the solution is effective or not. Still, we are recommending you follow this method first. This one is a maintenance procedure. It may happen that you do not get any problems with your device. Still, you can refresh the cache partition at least. It ensures that the Android device doesn’t create too many bugs while using the system cache.

If you want to clean the cache from your device, then do the following.

First of all, what you have to do is to power off your device.

Then, you have to press the Volume Up key and the Bixby key at a time and hold them. After doing that, you are required to press the power key and hold it for a few moments.

As soon as you see the Android logo on the screen, you have to release all the three buttons you hold until then.

After that, you get to see an ‘Installing system update’ message on the screen for 30 – 60 seconds. The message appears on the screen before appearing in the Android system recovery menu options.

You can tap on the Volume down button a few times to highlight wipe cache partitions.

Next, your task is to press the Power button to choose.

After that, you have to press the Volume down button to highlight the option Yes. Then, use the Power Button to select it.

As soon as the wipe cache partition method gets completed, the Reboot system now option becomes highlighted automatically.

At last, you have to hit the Power button to turn on the mobile phone again.

Install Android Updates:

When you install any update, you follow the most effective way to resolve the problem. If the wipe cache Partition procedure fails, check if there is any pending update in your mobile. If there is any, then fix the issue.

The Galaxy S9 comes with a default system that allows it to be set for downloading updates automatically. Therefore, you don’t need to put them for download as well as installation. Whether you have changed the default settings earlier, you need to go to the Settings option then. After that, move to the Software update option to check the updates.

Install App Updates:

We know that it is an android bug that causes the problem generally. However, sometimes an application can also trigger it. That’s why it is vital to keep all the apps updated. Otherwise, bugs can come from the app to your mobile phone.

  • To do this, you have to go to the Play Store app first and then open it.
  • After that, you have to move to the menu option.
  • Then,‌ click on the Settings option. You need to ensure that the device is set for installation of all updates automatically.
  • If you don’t want your device to download updates without your permission, you have to check them daily.

If you want, you can use third-party sources that are outside of the Play Store. Then, you need to confirm that all the applications receive updates from their app developers. Sometimes, devices available very recently can render some apps incompatible, which causes issues after that. A few apps are insignificant, whereas a few are disturbing. That is why it is better to keep all the apps on your phone updated always.

Reset Settings:

This method is quite similar compared to the factory reset. It reduces the need to delete user data, apps, etc. You need to follow the process if you are still getting the message on your phone screen. In this case, you have to go to the Settings first and then open it.

After that, your task is to click on the General management option.

Now, click on the Reset option.

Next, your job is to click on the Reset all settings.

At last, hit the RESET SETTINGS button.

Factory Reset:

When no other methods will work for your device, then follow this method. Here, you have to clean your phone S9. However, before doing this, ensure that you back up all your device’s files not to lose them.

  • To do a factory reset of your device, you have to back up your device’s internal memory. Have you signed into a Google account on your mobile phone? If yes, then your job is to activate the Anti-theft option. Then, you have to take the help of your Google credentials as it helps you complete the Master reset method.
  • When you are on the Home screen, you have to swipe up on an empty spot. Thus, you can open the Apps tray of your device.
  • Next, click on the Settings and then to Cloud and accounts.
  • After that, you have to hit the Backup and restore option.
  • Click on the Back up my data whether you are eager to move the slider to ON or OFF.
  • You can do the same with the Restore option. Just click on it and then move the slider to ON or OFF.
  • Next, you have to click on the back button and then move to the settings option. After that, you have to click on the General Management, then Reset, and Factory data reset, respectively.
