How To Fix Samsung Galaxy A9 Not Turning On After Drop
Problem: Last night I dropped my Samsung A9 on cement. I picked the phone up and the screen was cracked. I tried to turn it on and it would not power up. I’ve dropped this phone probably ~15 times and had it for about 4 months. Once I got home I plugged it into the charger to see if maybe it would be okay in the morning. About an hour after I woke up I noticed that the phone was displaying the charging icon and watched it quickly climb from 0% to 98%(in about 5 seconds). I figured the problem was solved and went to work. When I arrived at work the phone was off and unable to turn on again. I kept it on the charger for about 10 hours and it never turned on. When I got home I plugged it in again and about 30 minutes later I noticed it turn on again. Unlocked it once it was done booting and while waiting for it to load it cut off again. After that it tried to turn on maybe 7 times, but each time it would shutdown somewhere during the startup process. Now it will not turn on at all. I have tried a hard reset in multiple boot modes, but none will work. I am willing to and have experience working on electronic hardware if it is necessary.
Solution: It appears that this issue is already caused by a faulty hardware component that has been damaged by the drop. The phone has to be taken apart then checked to see which component is failing to work then if necessary have this component replaced. The best way to do this is to have the phone fixed at a service center as they will have all of the necessary tools available to perform this task. You can however perform some troubleshooting steps on your end to check if the problem can be fixed without the need of a service center.
Make sure the battery has sufficient charge
The first thing you need to do in this case is to fully charge the phone. Clean the charging port of the phone using a can of compressed air making sure that any dirt or debris stuck in it is removed. Once this is done connect the phone to its wall charger then let it charge.
Perform a soft reset
Although this is usually done to fix an unresponsive device it will also work in this case as the phone software will be refreshed. To do this just hold the power button and the volume-down button for around 10 seconds. Let go of the buttons once you feel the device vibrate and see the Samsung Galaxy A9 logo on the screen. Your phone will then reboot. Try checking if your phone will successfully turn on.
Start the phone in Safe Mode
Sometimes an app you downloaded from the Google Play Store can cause this particular problem. The best way to check if an app is causing the problem is to start the phone in Safe Mode since only the pre-installed apps are allowed to run in this mode.
- Turn the phone Off
- Press and hold “Power”
- At the “Samsung” logo, release “Power” and immediately press and hold “Volume down”
- After the phone finishes rebooting, release the keys. A “Safe Mode” watermark should be visible in the lower area of the home screen
If the issue does not occur in this mode then you should find out what app is causing the problem and uninstall it.
Wipe the cache partition of the phone
The phone will usually store cached data of apps in a special partition of its internal storage. This cached data allows the phone to open apps quickly making for a better mobile experience however there are instances when the saved data can become corrupted which can cause issues on the device. To eliminate this factor you will need to wipe the cache partition of the phone.
- Turn the phone Off if necessary
- Press and hold “Power” “Volume down” and “Home”/”Bixby” at the same time
- At the Android screen, release the buttons and wait for access to Android Recovery
- Press “Volume down” to navigate the menu to highlight “Wipe cache partition”
- Press “Power” to select the highlight
- Finally, highlight “Reboot system now” and press “Power”
Check if the issue still occurs
Perform a factory reset
One last troubleshooting step that you should consider doing is a factory reset. This reverts your phone to its original factory condition. Take note that this will erase your phone data.
- Turn off the phone.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- 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).
- Press the Volume down key several times to highlight ‘wipe data / factory reset’.
- Press Power button to select.
- Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
- Press Power button to select and start the master reset.
- When the master reset is complete, ‘Reboot system now’ is highlighted.
- Press the Power key to restart the device.
After the reset do not install any apps in your phone just yet. Try to check first if the issue still occurs. In case it does then you will need to bring the phone to a service center and have it checked.
