J3 Will Only Turn On When Connected To Charger

Problem: Hello I have a Samsung Galaxy J3 AT&T  Running Android Version 8.0 and when powering it on it will start up go to the first part “Samsung” and then shut back off and other times if I Hold The power Button it will go to “Samsung”  then the Samsung Galaxy J3 then power back off , Now if I have it with the charging cable plugged in and power it on it will power all the way on no problem it will do all the above even with a fully charged battery   when charging it charges fine doesnt get hot or even warm while doing so when fully charge it will last 24 hrs or so and it doesnt discharge fast or anything I have tried factory resetting it even and that was no help

Solution: If you have already performed a factory reset then it’s safe to eliminate the possibility that a software glitch is causing the problem. What you can do right now is to try to clean the charging port of the phone using a can of compressed air then use a different charging cord and wall charger to fully charge the phone. Once the phone is fully charged try to check if the problem still occurs. If it does then this is most likely caused by a faulty hardware component, possibly the power IC. The best thing to do in this case is to bring the phone to a service center and have it checked.

J3 Freezes And Lags

Problem: Hi guys I found you via Youtube and I hope you can help me get my phone working again. I have followed all the reset suggestions but no good. I have factory reset the phone but it still displays freezes and extreme lagginess on the touch screen making setting up the phone now in its virgin state virtually undoable. In order to register one screen click/input command I have to keep tapping sometime over 100 taps to get through to the application command required. I have one month left on the warranty so in theory I could get Samsung to repair it, the only problem being I live in Gibraltar in the south of Spain and the nearest Samsung Service centre is Marbella, approx 80 km away and I don’t speak Spanish (I’m from UK out here for family reasons).

I have a Mac running El Cap 10.11 and can run Windows 10 if need be.

On the phone I was running Android Oreo which I upgraded recently, but I think there was another update about 6-8 weeks ago which is when all the problems started. SO I wondered would rolling back to old software clear the glitch? I have download but not opened

1) Nougat firmware,

2) Latest Odin,

3) Samsung Smart Switch (in order to ensure I have the necessary drivers).

Altering the firmware will void my warranty so I need to be sure rolling back to previous software will completely cure this problem. The Samsung online chat advisor says it could be a hardware problem in which case I need the warranty repair checked first. So as it stands my phone has been reset but I cannot really get into it because of the screen input issue. What do you think guys?

Solution: If your phone is still under warranty then I don’t recommend that you flash it with an older firmware file as this won’t probably solve the problem. I suspect that this is already caused by a faulty hardware component and since the device is still under warranty the best thing to do is to have the phone repaired at a service center.

J3 Not Turning On After Drop

Problem: The phone was dropped and now the screen is dead. The only signs of life are a constant blue LED or a constant amber LED. It comes and goes as I try different key combinations based on online articles and recovery tools! No luck yet. I want to attempt to recover some files from the phone. Any ideas? Thanks!

Solution: The best thing you can do in this particular case is to do a soft reset. This is done by pressing and holding both power and volume down buttons for at least 10 seconds. Your phone should restart after this.

If your phone is the variant with a removable battery then take out the battery and press the power button for a minute. Reinsert the battery then turn on the phone.

In case the battery does not have sufficient charge then you should charge the phone first using its wall charger then repeat the steps listed above.

In case the issue still persists then this it’s likely that the problem is caused by a hardware component that got damaged by the drop. The best thing to do right now is to bring the phone to a service center and have it checked.

J3 Randomly Restarts

Problem: I am having a problem with my Samsung Galaxy J3 restarting on its own. The random restarting of my phone happens when I play music on an app called Spinrilla. If I play nonstop music for about 30 minutes or more, my phone will automatically restart and I feel really frustrated. Sometimes, my phone would restart when I am on social media or texting a friend and family member.

Solution: The first thing you need to do is to check if the problem is caused by an app you downloaded. Start the phone in Safe Mode then check if the issue occurs in this mode. If it doesn’t then it could be caused by an app you downloaded. Find out what app this is and uninstall it. In case the issue still occurs even in Safe Mode then proceed with a factory reset. Make sure to backup your phone data before doing the reset. Once the reset is complete do not install any apps in your phone yet. Try to check first if the issue still occurs. If it does then you will need to bring the phone to a service center and have it checked.
