J3 Randomly Rebooting

Problem: Was recently given a J3 that is approximately a year old. At the beginning of this year I experienced a bad battery which was confirmed after a voltage check at battery world where I purchased a brand new battery and had it replaced . Recently my phone has begun to randomly reboot (switching off completely, rebooting to the black samsung screen, then my lock page) it tends to do this when hot, connected to the internet or opening apps such as discord or snapchat as well as games. I’m not sure what’s happening. I’ve tried simple troubleshooting such as performing resets myself, uninstalling apps to see if they are causing issues etc. I want to avoid a factory reset as my phone contains my learner driver logbook app and various other important data. Would just like to see if i can get some help here before spending money on a technician in a store to look at it. I have also noticed a slow or sluggish response during or around this issue.

Solution: Does your phone have a microSD card installed? If it does and it has some corrupt sectors then this could be causing the problem. Try removing the card then check if the issue still occurs.

In case the issue persists then you will need to consider doing a factory reset. Make sure to backup your phone data before doing the reset.

If the above steps fails to fix the problem then you will need to bring the phone to a service center and have it checked.

J3 Freezes Then Shuts Down

Problem: I currently own a J3 that is tmobile but is factory unlocked. I bought this off of ebay about 4 months ago. The phone was working fine until maybe a week ago. Now my phone freezes and will shut down. I have to do a soft reset to get it to turn back on. When I do it will go to a little green guy and in the upper right hand corner will say Could Not Do Normal Boot ODIN MODE . I’ve tried to do everything from wiping the cache and factory reset the phone. Also I can’t reset or reboot the phone in the bootloader screen it will just freeze and it also freezes if I pick up a call. Any way you can help me I’d be extremely grateful as I don’t have a Samsung warranty because I bought the phone from a third party seller on Ebay.

Solution: The best troubleshooting step that you can do for this particular problem is a factory reset from the recovery mode. Take note that this will erase your phone data. In case this does not fix the problem then this is most likely caused by a faulty hardware component. The best thing you can do right now is to bring the phone to a service center and have it checked.

J3 Is Not Reading SIM Card

Problem: HI, I have SAMSUNG GALAXY J3. The Problem is Sim card does not work in  my device, it works in other devices though. So there is no SMS, no Calling and internet connectivity. At right side at the place of network there comes ‘O’ as no network symbol. Easily gets connected to WI-FI and works well. Pls provide solution to the problem. Thank you.

Solution: Since you have already verified that your SIM card is working in other devices then the problem could be caused by a faulty SIM card reader. Try using a can of compressed air to clean the SIM slot of your phone. Once this is done insert the SIM card then check if the issue still occurs. If it does then the SIM card reader assembly of the phone might need to be replaced. The best thing you can do right now is to bring the phone yo a service center and have it checked.

J3 Can’t Make Calls After Software Update

Problem: Woke up, turned on my phone and it showed updating Android.  When it finished it showed Android 7.0. Realized soon after that I wasn’t receiving nor could I dial out calls.  I went through many diagnostics with T-Mobile. Even went to the T-Mobile store and got a new SIM card. No change.  Obviously the new OS was the culprit, but nobody’s owning up to it. Thanks in advance for your help

Solution: It’s very likely that the problem is caused by old software data that has not been completely removed from the phone. The best thing you can do right now is to backup your phone data then do a factory reset.
