How To Fix Samsung Galaxy A9 Keeps On Crashing

Problem: I have just bought a UK-purchased Samsung A9 from a colleague as an urgent stopgap after killing my last phone. It was unused. There are no legit Samsung dealers in the country that I’m working in. Internet connection is patchy and WiFi is obtained with a 3g router (Zain). The phone started out fine but it is now crashing constantly. These crashes seem to correspond with failures by the phone to properly update Samsung apps (such as Mail). It overheats at the same time. I have VyprVPN but the crashes happen regardless of the VPN being on or off. The crashes present as either being unable to get off the sleep screen, or as seeing just the background and screen flickering on and off. Then only thing which fixes it is a restart. A podcast being played over a Bluetooth speaker is unaffected. I couldn’t find an equivalent problem on here, so any tips are happily received!

Solution: Before troubleshooting this issue it’s best to make sure that the phone is running on the latest software version. If an update is available then I suggest that you download and install this first in your device.

When a phone keeps on crashing on of the main culprit behind this is a software glitch which is what we will be troubleshooting first. Follow the steps listed below to fix the problem.

Remove the micro SD card of the phone

If your phone has a micro SD card then I suggest that you remove it. If this card has some corrupt sectors and the phone access data in this card then it can cause the device to crash. In case your phone does not crash with the SD card removed then I suggest that you get a new micro SD card.

Start the Galaxy A9 in Safe Mode

A good way to check if an app you downloaded is causing this problem is by starting the phone in Safe Mode. When your phone is started in this mode only the pre-installed apps are allowed to run making it easier to determine if an app you downloaded is the culprit.

  • With the phone turned on press the turned on start pressing the Power button.
  • If the menu pops up tap Power off and tap the option to open Safe mode.
  • Wait for a few moments.
  • The device is now booted in Safe Mode

In case the issue does not occur in this mode then you should find out what app is causing the problem then uninstall it.

Wipe the cache partition of the Galaxy A9

Your phone will usually store temporary system data which can help speed up certain apps. This temporary data however can become corrupted which can cause certain issues to occur on the device. To check if this is what’s causing the problem you will have to wipe the cache partition of your phone.

  • Turn off your device.
  • Now Press and hold the Bixby, Volume Up and Power buttons for few secs.
  • After you see the Android Logo is displayed, release the Power and Bixby button, but keep holding the Volume Up button until the Recovery Mode screen shows up
  • Now you can see the Android System Recovery Menu option.
  • Use volume keys to highlight wipe cache partition and use the power button to select it
  • Confirm by selecting yes option

Backup your Galaxy A9 data then do a factory reset

One last troubleshooting step to consider is a factory reset. This will revert your phone back to its original factory condition. Make sure to backup your phone data as it will be erased in the process.

  • Go to  settings of your phone.
  • Now Scroll down and select General management option
  • Tap on Reset option
  • Choose  Factory data reset
  • Select the option ‘Erase everything’ and then wait till your device gets rebooted with the factory settings.

In case the issue still persists even after performing the steps listed above then you should have this checked at a service center.
