Galaxy J7 apps keeps freezing when loading updates or when syncing, other issues

Hello #GalaxyJ7 users! Today we answer three more issues that you sent to us. Unlike the more popular Samsung flagship phones, the J7 is a perfectly balanced phone in terms of performance, design, and affordability. And as far as problems with this model are concerned, we’re receiving significantly less reports all over so we think it’s a pretty robust device. We hope though that the solutions we provide below will help our growing Android community.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy J7 apps keeps freezing when loading updates or when syncing

Hello. My Galaxy J7 keeps giving me a problem, and I can’t seem to find where it comes from. The standard Browser app and Chrome both work fine. Also, YouTube and the Play Store – among other apps – work as they should. But in some apps, it will forever stay in a loading mode, typically showing a rotating circle (that does keep moving). Facebook: Everything works fine, but when I go to a page I manage and want to read the page’s chat messages, or view the page’s new Likes, it “freezes.” E-mail: The standard client does update the inbox, but when I click on a message to read it, it ‘freezes’. Gmail: Same as E-mail. Outlook: I recently installed this, so I need to add my account. I can get to the screen to fill in my email address, but after that, again, it  “freezes.” TubeMate (non-Store app): This YouTube client lets you download videos. It normally opens a browser version of YouTube within it’s own frame. It now ‘freezes’ at startup, so I can’t even get to my already downloaded videos. Quora: The app opens, but none of the pages/tabs work, they just keep loading. These problems are the same on WiFi and on network. Please help! Cheers. — Ron

Solution: Hi Ron. The cause of your problem can vary depending on the state of the software. In a lot of similar cases, it’s a cache issue so we suggest that you regularly wipe the cache partition to ensure that the system cache has minimum bugs as possible. This is how you do it:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the device logo screen displays, release only the Power key
  4. 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).
  5. Press the Volume down key several times key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. Press the Volume down key to highlight ‘yes’ and press the Power key to select.
  8. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

If you’re running Android Marshmallow or Nougat, you can also delete cached data under Settings>Device maintenance>Storage>Storage settings.

Performance issues when loading apps can also occur if a device is running out of RAM so do your phone a favor and simply hit CLOSE ALL button after hitting the Recent Apps key. Doing so will free up RAM space so the system can allocate them to the app you’re actively using. An alternate way to clear RAM on devices running Marshmallow and Nougat is this: Settings>Device maintenance>Memory>CLEAN NOW.

Problem 2: Galaxy J7 does not automatically reconnect to network, won’t connect to network when charging

I write this to discuss about the data problem with my Samsung Galaxy J7(2016) model.  If my mobile is idle for some time the data speed is lost and to regain it i have to switch off the mobile and again switch on. Even this will not work if it is connected to the charger. So i have to disconnect the charger, switch off the mobile and again switch on. Though no data speed, network it is shown as connected to the internet. I have taken up this matter with the network provider and they blame it over the handset. I have done lot of troubleshooting like changing the sim slot, resetting the APN, airplane mode on / off etc. Another observation is that it is happening in only one network area (in my office) or that’s what i could observe. Sounds crazy!! With regards. — Hari

Solution: Hi Hari. Some devices, due to the unique state of their software and the apps installed, won’t automatically reconnect to the network if disconnected for some time. A user will have to restart the phone in order to re-establish a connection. This is not an ideal operation but since there’s no way to know for sure what might be the cause, you can either go with the workaround (of restarting the device everytime), by doing more drastic troubleshooting like factory reset. Due to the nature of this problem, a factory reset may not fix it permanently and follow-up steps may be needed such as identifying possible problematic apps, or uninstalling apps.

For reference, these are the steps on how to factory reset your J7:

  1. Back up data on the internal memory. You can use Smart Switch for this.
  2. From the Home screen, tap the Apps icon.
  3. Tap Settings.
  4. Tap Backup and reset.
  5. If desired, tap Back up my data to move the slider to ON or OFF.
  6. If desired, tap Restore to move the slider to ON or OFF.
  7. Tap Factory data reset.
  8. Tap Reset device.
  9. If you have screen lock turned on, enter your PIN or password.
  10. Tap Continue.
  11. Tap Delete all.

Once you’ve factory reset the device, try to see if the problem continues. Make sure not to install any app during this observation period. If the problem remains, your next move is seek a phone replacement (if you think this issue is too much). Otherwise, continue with installing your apps and observing the phone again. If the problem only returns after you’ve re-added your apps, one of them must be the cause. Uninstall apps until you’ve removed the culprit.

Problem 3: Galaxy J7 keeps on rebooting on its own, how to flash J7 bootloader, flashing issue

I got a Samsung Galaxy J7 Prime, Model: SM-G610F and it keeps on rebooting after 2-3mins tops. First I tried Firmware upgrade and downgrade, I download these firmware from and tried latest firmware and oldest firmware and then did a soft reset (Wipe Cache Partition) and finally Hard Reset each time I did a firmware upgrade & downgrade. The issue still exists, it kept on rebooting. I don’t want to assume that it is hardware issue. Hope you can assist me with my problem. Thank you and awaiting your kind assistance and support. — Uere Bonraawa

Solution: Hi Uere. Android troubleshooting is simple. Try not to make it otherwise. The general rule is to exhaust all software troubleshooting first. If they won’t help, you can assume it’s a hardware problem.

We understand you’ve already tried reflashing the firmware and hard resets multiple times. What we want you to try at this time though is to ensure that you also reflash the bootloader. Bringing it back to its stock state is critical to ensure that you cover all bases. If the phone continues to reboot on its own after that, send it in for repair or replacement.

For reference, here are the general steps on how to reflash a bootloader. The exact steps may be slightly different so try to do some research to avoid bricking the phone.

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.
