How To Fix Samsung Galaxy S9+ Stuck On Software Update Screen

Problem: I began a system update on my Samsung Galaxy S9 plus at 10 pm last night. And now 9 hours later the phone is stuck at 35% of the update. The phone shows the blue update screen with the Android robot and the arrows on the robot are turning. But the update percentage is not increasing. I’ve tried to turn the phone off by holding down the power button and volume down button for 10 seconds and nothing happens. At this point I will not do a factory reset because I have some pictures that are not backed up. My biggest fear is that I will loose the pictures! Thanks for your help!

Solution: It’s very likely that this issue is caused by a software glitch which is why we will be concentrating our troubleshooting efforts on the software side of the device. Before performing the troubleshooting steps listed below I suggest that you remove the microSD card of the phone if you have one installed.

Do a Soft Reset

The first thing that you will need to do in this particular case is a soft reset. This will usually fix issues caused by minor software glitches as it will refresh the phone software. This is also called as a simulated battery pull as it disconnects the phone from the battery.

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

Check if the phone will update successfully.

Update the phone using the OTA method

  • From the Home screen, swipe up on an empty spot to open the Apps tray.
  • Tap Settings > Software update > Download updates manually.
  • Wait for the device to check for updates.
  • Tap OK > Start.
  • When the restart message appears, tap OK.

Update from a computer using Smart Switch

Make sure to backup your phone data before performing this procedure.

  • Download and install Samsung Smart Switch that is compatible with your computer from http://www.samsung.com/us/support/smart-switch-support/#!/.
  • Connect the cable to a compatible USB port on your computer.
  • Connect the other end of the cable to your mobile device.
  • Allow your computer to install any required drivers for your device. This process may take a few minutes.
  • Open Smart Switch on your computer, and allow it to make the connection.
  • If a software update is available for your device, Smart Switch will automatically prompt you to update. At any time, you can click Update.
  • Click Update to begin downloading the necessary files.
  • Click OK to proceed.
  • Your device may turn off and on a few times during the update process.
  • Once complete the device will return to the Home screen.

In case the phone software does not get updated then proceed with the additional troubleshooting steps listed below.

Wipe the cache partition of the phone

The phone system cached data is used to speed up the access to your phone apps. Sometimes this data can get corrupted which results in issues occuring on the device. To check if a corrupted cached data is causing the problem you will need to wipe the cache partition of the phone from the recovery mode.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • When the 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 to highlight “wipe cache partition.”
  • Press the Power key to select.
  • Press the Volume down key to highlight “yes” and press the Power key to select.
  • When the wipe cache partition is complete, “Reboot system now” is highlighted.
  • Press the Power key to restart the device.

Check if the software update  will be completed.

In case the issue still persists then you should consider performing a factory reset. 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.

Do not install any apps after the reset has completed. Try to update your phone software first. In case the issue persists then you will need to bring the phone to a service center and have it checked.
