Samsung Galaxy J3 most common issues and how to resolve them

Samsung Galaxy J3 is more than a viable option in the lower low-budget category. If you’re not exceptionally demanding user and a loyal fan of Samsung handsets, J3 is well-suited for the job. However, for this and the majority of handsets, there are always issues that need to be addressed.

For that purpose, we prepared a list of most frequently reported problems provided by J3 users. Of course, we provided you with the proper troubleshooting steps, so make sure to check for your individual problem. We hope that you’ll find the remedy for your ache in the list below.

Battery issues

First, the main reason why people seem to deem the overall usability of this handset lackluster is the battery. The battery on J3 isn’t bad per se, and it certainly won the battle with the competition in 2016. Nonetheless, it’s the software within the device that drains the battery. So, even though the 2600 mAh battery is well-performing, there are still ways to improve the battery life and reduce the consumption. For that purpose, we enlisted  some of those workarounds below:

  • Disable background apps. You can either do it manually within Settings > Application manager or by using the Smart Manager (Device Maintainance). Navigate to Settings > Device Maintainance > Unmonitored apps, and clear apps that are using the battery extensively while working in the background.
  • Use Battery Power Saving mode. Tap Settings > Device Maintainance > Battery and use one of two battery saving modes.
  • Disable GPS. You can either disable GPS permanently until an app acquires it or reduce the accuracy of the location service by changing location method to Phone only. Tap Settings > Connections > Enable Location > Location method, and switch to Phone only.
  • Disable Bluetooth.

In addition, make sure to uninstall the redundant and unused apps that are hogging on your device resources. We hope that with those, you’ll be able to extend your battery’s life.

Overheating issues

Overheating isn’t exactly a common problem, but it does affect certain users. And once it occurs, it’s likely to make your overall experience with the J3 quite hard to cope with. Moreover, if the phone is overheating over extended periods, you may encounter more than lags and stutters. Namely, in the worst case scenario, you can expect hardware failure. Obviously, it’s essential to address the overheating issue before it’s too late.

There are various reasons for this occurrence, and we advise you to check the following steps in order to prevent them:

  • Don’t use your phone while charging.
  • Check the resource hogging apps in the background.
  • Make sure that your battery isn’t faulty.
  • Remove the casing.
  • Don’t expose your handset to heat sources over an extended period of times.

Wi-Fi issues

Connectivity issues are generally not unusual for a multitude of Android handsets. Some of them suffer from the lackluster signal, while others are known for connection crashes. Either way, it’s hard to use your device as intended without the proper Wi-Fi connection. Almost impossible. Samsung Galaxy J3 isn’t exactly known for Wi-Fi issues, but some isolated cases are still enough for us to address the issue.

For that purpose, we advise you to follow the instructions below in order to troubleshoot Wi-Fi issues on your J3:

  • Forget Network and connect again.
    1. Press and hold on Wi-Fi icon in the Notification panel to open Wi-Fi settings.
    2. Click on the network you need to re-establish.
    3. Tap Forget.
    4. Restart your J3 and reconnect again.
  • Reset network settings.
    1. Tap Settings.
    2. Open Backup & reset.
    3. Tap Reset Network Settings.
    4. Enter password/PIN/pattern if prompted and tap RESET SETTINGS.
    5. After the restart, you should be good to go.
  • Disable IPv6 protocol on your router.
  • Use 5 GHz instead of 2.4 GHz and vice versa.
  • Wipe the cache partition.
    1. Turn off the device. Make sure that your battery is not critically low.
    2. Press and hold the Volume Up key + Home key + Power button.
    3. Once the logo appears on the screen, release the Power button while holding the Volume Up key + Home key.
    4. Wait for the Android logo to appear and release all buttons.
    5. Use the Volume Down key to find and highlight the ‘wipe cache partition’ option.
    6. Use the Power button to confirm the selection.
    7. Now, scroll down with the Volume Down key and highlight ”Yes”.
    8. Press Power button to select.
    9. After the procedure is finished, restart your device and check for changes.
  • Disable Smart Network Switch.
    1. Connect to Wi-Fi and tap Settings.
    2. Open Connections.
    3. Open Wi-Fi.
    4. Tap the 3-dot menu in the right corner.
    5. Choose Smart network switch.
    6. Toggle the feature Off.

Mobile data issues

As same as with the Wi-Fi, some users experienced issues with the Mobile Data. Some of them weren’t able to use the 3G/4G as intended due to SIM card issues, while others encountered issues with unexpected signal drops and similar irregularities. Most of the time, the issue is closely related to an inappropriate position of the SIM card. Cellular signal drops are the best way to find out is your SIM card properly inserted in the SIM tray.

On the other hand, there are also some software issues that need to be examined, since the problem isn’t exclusively connected to the SIM card. Follow the instructions below to troubleshoot the mobile data issues on your Samsung Galaxy J3:

  • Reset your device.
  • Switch Network type. Settings>More>Cellular Networks>Preffered Network type. Select LTE and save settings.
  • TurnAirplane mode ON and then OFF.
  • Reset APN settings. Go to Settings > Connections> Mobile Networks > Tap Access Point Names > More > Reset to default.
  • Reset Network Settings. Navigate to Settings > Backup & reset > Network settings reset>Reset Settings.
  • Remove SIM card and put it back again.
  • Disable Bluetooth.

With that, you should be able to use the mobile data just like before.

SD card issues

SD card is of utmost importance if you want to store more multimedia since the device is limited to 16 GB of internal storage. However, users reported issues with SD cards, too. Namely, some of them weren’t able to transfer the data from internal storage to SD. Other – well – their J3 wouldn’t even recognize the SD card or suddenly unmounts it. For that purpose, we advise you to follow the steps below, since there are multiple ways to address this issue.

  •  Power Off your device and remove SD card from the slot. Clean the slot with the compressed air and re-insert the SD card.
  • Backup your SD card on your PC and format it. Make sure to format or reformat the SD card and copy the backed-up content again.
  • Wipe the cache partition.

Unexpected shutdown issues

If we take into consideration all enlisted issues of J3, this is probably the most intimidating one. Some users pointed out the major issue with regard to sudden restarts or even shutdowns. There are few reasons for this occurrence and we’re presenting them below:

  • The phone is overheating.
  • Custom ROM causes issues with the hardware.
  • Hardware failure.

For that purpose, we advise you to look at presented solutions for overheating issue and flash your device again. In addition, you can try to boot into the safe mode and examine the behavior. If the phone is working as intended, make sure to delete all lately installed apps. In contrary, if the device is still failing, it’s likely that we’re looking at hardware malfunction. So make sure to take your Samsung Galaxy J3 for repairs.

SIM card issues

You would imagine that this is a problem similar to the one with the SD card. Symptoms are obviously different, but the reason is, most of the time, inappropriate placement. On the other hand, with the latest updates, users with SIM card issues (sudden loss of network signal, mobile data loss, and ”Please insert SIM card” error) are rightfully suspecting the software involvement, as well. For that purpose, we prepared a list of possible solutions you should take into consideration:

  • Restart your device.
  • Reinsert SIM card and/or switch SIM 1 and SIM 2 positions if you’re using dual-SIM option.
  • Try your SIM card in another handset to make sure it’s working.
  • Select ”3G only”. Navigate to Settings > Connections > Mobile Networks > Network Mode, and choose ”3G only” from the dropdown list.
  • Select proper access point.
  • Disable Bluetooth temporarily.
  • Boot in the safe mode and look for changes in the signal behavior.
  • Wipe cache partition.

Bluetooth issues

In the plethora of reported issues, it wouldn’t be fair to skip on Bluetooth issues. Bluetooth-related issues that are reported, mostly refer to failed pairing or unstable connection with the paired device. This mostly occurs in a pairing J3 with the car board. Or lack of it, to be exact. Luckily, if we exclude the hardware failure of the Bluetooth radio, there are some steps you can take to troubleshoot this problem.

  • Disable other network services while using Bluetooth (Wi-Fi, LTE, 3G).
  • ”Forget” device and try to pair again.
  • Wipe partition cache (process explained above).

That should do it. If you have alternative issues or solutions for the problems we presented above, make sure to tell us in the comments section below. We’ll be glad to help you. Thanks for reading and have a good day.

I’ve had my Samsung Galaxy J3 phone for a year or so with no problems until now. The problem started yesterday but is much worse today. Yesterday, the screen would go dark shortly after I would start to read or write an email or message. But I was able to complete the task each time. However, today, the screen goes dark almost immediately after I swipe to open the screen and I cannot get the screen to light up except for a brief second. So essentially I cannot do anything with the phone today. Anyone have any experience with an… Read more »

I have the J3 Luna Pro – I have been using the Golf Pad (premium) for about a month. I used it 3 times a week on the golf course. About a week ago I was unable to pull up the course I was playing. At home I can pull up the course and all details. Also i am now unable pull up other programs when I am away from home. What happened to cause this?
