S9 Stuck In Optimizing Apps After Software Update

Problem: My phone prompted me to download and install the latest android upgrade. I did, and the screen blocked with the message: Upgrading Android – optimizing app 85 of 85. I can’t remove the battery . What shall I do please?

Solution: To fix this problem you should try to do a soft reset first. This is done by pressing and holding both power and volume down buttons for at least 10 seconds. When the phone restarts check if the issue still occurs. In case it does then proceed with the additional troubleshooting steps listed below.

  • Start the phone in recovery mode then wipe the cache partition of the device. Restart the phone then check if the issue still occurs.
  • Backup your phone data then do a factory reset.

S9 No LTE Signal After Software Update

Problem: I have a Samsung Galaxy S9 unlocked  in which i have Total Wireless for service. LTE service has been replaced with 3G or no service at all in the same physical areas I’ve had LTE, after the software update. Also says no data connectivity during phone calls. I’ve checked the network settings & such. IDK what to do! Help! Please and thank you so much

Solution: If you have been getting a good LTE signal in your location prior to the software update then it’s likely that the problem is caused by a wrong APN setting.

  • Name: Total Wireless
  • APN: tracfone.vzwentp
  • Proxy: Not Set
  • Port: Not Set
  • Username: Not Set
  • Password: Not Set
  • Server: Not Set
  • MMSC:
  • MMS Proxy: Not Set
  • MMS prt: Not Set
  • MCC: 311
  • MNC: 480
  • Authentication Type: Not Set
  • APN Type: default, dnu, supl
  • APN Protocol: IPV4V6
  • APN Roaming Protocol: IPV4
  • Enable/disable APN: APN Enabled
  • Bearer: Unspecified
  • MVNO Type: None
  • MVNO Value: Not Set

If your phone is already using the correct APN settings but the problem still persists then I suggest that you backup your phone data then do a factory reset as this could be caused by a software glitch.

S9 Cannot Open Facebook Notifications

Problem: I recently upgraded to an S9, as did my husband.  He has no issues with his. However, my Facebook icon badge shows notifications (and the numbers appear to be accurate), but when I click on the notifications icon within the app; it circles and circles then finally comes up with a notification that  it cannot connect. All other features within the app work appropriately as well as notifications for other applications I use. For version below: when I open my phone, it says Android version 8.0.0, but I am unsure if it is Oreo or not.

Solution: Try checking first if the problem is caused by a slow Internet connection by connecting the phone to a different Wi-Fi network or by using your mobile data network. If the issue persists then it’s likely that the problem is caused by some glitch in the Facebook app itself. Just uninstall the Facebook app from your phone then install a fresh version from the Google Play Store.

S9 Screen Went Dark

Problem: Hi, I have a Samsung Galaxy S9.  It’s been playing up recently. This morning the screen was very dark and I went into settings to try and turn up brightness.  I completely appear to have lowered it instead. My screen is completely dark so I can’t get in to set brightness again as there is nothing to see.  Please help – I am in a foreign country at the moment and urgently need to contact family

Solution: To fix this problem try doing a soft reset first. This is done by pressing and holding both power and volume down buttons for at least 10 seconds. Once the phone restarts and the screen is still black then you should start the phone in recovery mode. If the screen works in this mode then I suggest that you do a factory reset here. Take note that the reset will erase your phone data.

If the above steps fails to fix the problem then this is most likely caused by a faulty hardware component already. The best thing to do right now is to bring the phone to a service center and have it checked.

S9 Unfortunately Android System Has Stopped Working Error

Problem: I have an S9 that worked fine a few days ago.  Now I cannot share pics from the gallery. I get a message that says “unfortunately android system has stopped”.  If I open the app again I get a message that says “android system keeps stopping”. I can still share from google photos, but not the gallery app.  I’ve reset all app preferences, deleted cache and data and have restarted the phone a few times. I’m hoping to not do a factory reset. Any solutions?

Solution: You can try wiping the cache partition of the phone from the recovery mode then check if the problem still occurs. If it does then you should backup your phone data then do a factory reset.
