J3 Mobile Data Not Working Unless Airplane Mode Is Toggled

Problem: Bought late march..problem since day 1. new service to boost with this cell..it won’t connect to data. When it does it will stop. i have to turn on airplane mode, then back off…i contacted boost , who sent me to samsung.the guy told me to do the airplane trick..said it’s normal operation..turning this damn thing on and off 30 times a day is anything but normal..any ideas besides turning it into a paperweight..it’s a shame boost nor samsung wouldn’t warranty a phone I had less than 8 hrs for this prob..it’s not my location..both my sister and her bf live with me..their idea I switch…their phones do not do this…

Solution: Since your mobile data temporarily works whenever you toggle the Airplane Mode setting of your phone then what you will want to do is to concentrate on troubleshooting the software of the phone.

  • Try starting the phone in Safe Mode first then check if the problem occurs in this mode. If it doesn’t then there’s a chance that an app you downloaded is causing the problem since only pre-installed apps are allowed to run when the phone is in Safe Mode. Find out what app this is and uninstall it.
  • Wipe the cache partition of your phone from the recovery mode.
  • Backup your phone data then do a factory reset. Once the reset is complete do not install any apps in your phone yet. Try to check first if the issue still occurs.

In case the above steps fails to fix the problem you should try inserting another SIM card in your phone. You can also try checking your SIM on another phone and check if the ame issue occurs. In case it is found out that the SIM is causing the problem then you should have this replaced.

Should the issue persist then you need to bring the phone to a service center and have it  checked.

J3 Charges But Does Not Turn On

Problem: My friend has a samsung galaxy j3 and the phone does. It charges. The battery icon appears as if the battery was charging but then it starts blinking. After an hour, the phone still did not turn on. When the power, home and volume up buttons are held down, the screen showing the model and brand appears briefly and then turns back off. If you could help us, that would be great.

Solution: What you will want to do in this particular case is to clean the charging port of the phone using a can of compressed air. Once the port has no more dirt or debris in it try charging the phone for at least 20 minutes using a different charging cord and wall charger. After this, disconnect the phone from the charger then depending on the year model of the phone perform the steps listed below.

If this is a 2016 model with a removable battery

  • Remove the battery and microSD card ( if one is installed)
  • Press and hold the power button for at least a minute
  • Reinsert just the battery then turn on the phone

If this is  2017 model with a non-removable battery

  • Press and hold the power and volume down button for at least 10 seconds. Your phone should restart after this.

In case the above steps fail to turn on the phone then you might need to have the battery of the phone replaced. If the battery is not causing the problem then it could be caused by a faulty component in which case you will need to have the phone checked at a service center.

Solution: To be able to send and receive an MMS you will need to make sure that you have an active mobile data subscription since this an MMS uses a data connection. Your phone should also have the correct APN settings.

  • APN Name: H2O APN

  • Username:
  • Password:
  • Server:

In case your mobile data is active and your phone has the correct APN setting then you should proceed with the troubleshooting steps listed below.

  • Clear the cache and data of the text messaging app from the application manager. Check if the issue still occurs.
  • Try to check if the problem occurs in Safe Mode. If it doesn’t then it could be caused by an app you downloaded. Find out what app this is and uninstall it.
  • Wipe the cache partition of your phone from the recovery mode.
  • Backup your phone data then do a factory reset.

Solution: When the issue occurs is your phone connected to a Wi-Fi network or is it using the mobile data network?

If the phone is connected to a Wi-Fi network

  • Forget the Wi-Fi network from your phone.
  • Restart the phone and the router.
  • Connect to the Wi-Fi network.

If the phone is using a mobile data connection

  • Make sure that the mobile data service of the account is active and that there is still enough data bandwidth left.
  • Make sure that the signal strength from the network is strong.
  • Try turning off the phone then remove the SIM card. After a minute reinsert the SIM card then turn on the phone. Check if the issue still occur.

In case the above steps fails to fix the problem then you should consider performing a factory reset. Make sure to backup the phone data before doing the reset.

J3 Screen Is Black After Drop

Problem: Samsung Galaxy J3- I dropped my phone the other day, and the screen won’t come back on. It can still be called, the alarm clock goes off as scheduled, and it makes the appropriate sounds when it is plugged in or the volume is turned on. I can hear it receiving texts and emails. I tried the soft reset, and it did nothing. What can I do? What is the most economic option?

Solution: Unfortunately in this case this it looks like the display has been damaged by the drop. The best thing that you can do right now is to bring the phone to a service center and have it checked.

J7 Photos Are Inaccessible After Interrupted Copy To Laptop

Problem: I was going to download some phone photos to my laptop. The process stopped and the laptop read it wasn’t responding. When I unplugged it all, there were 28 random photos which all had the date of July7 (none were taken on that day!) AND now when I go to download, I go to DCIM and then it shows albums in the photos area. Camera is not one of them. It doesn’t exist. I’ve tried the soft start thing several times. I am a bit confused as to what to do next! I did discover something odd. I took some photos and they are in another photo marked camera. One with the camera icon on it. The other 158 or so photos in the camera folder (it isn’t hidden) are inaccessible. I can manually move them to a new folder. the 28 are now in a folder marked NOT July 7. But, the others are still locked in an album that doesn’t exist. Crazy? yes. I am betting something was tweaked when I put the USB into the laptop and it didn’t respond….

Solution: If the transfer of data got interrupted such as what has happened in this case it will usually lead to data corruption. The best thing that you can do right now is to try to use a data recovery software to recover the photos that can’t be accessed.
