Galaxy J3 Gets Warm When Charging Not Turning On

Problem: Hi,   Thank you for your time and answers to all of our questions in advance.Samsung Galaxy J3  phone.This is what has happened with this wonderful phone I have had the pleasure of using for years.   About 3 weeks ago I plugged it in to recharge the battery for the sake of recharging it. I noticed the phone had become very warm, having been in a cool kitchen guarded from sunlight.  So I bought a new Samsung battery from a seller in Ontario said it is a Samsung battery installed it and tried to turn the phone on. No go… so I plugged the phone in to charge the battery and for a moment I saw the battery showing 0% charged and a green light inside the outline of the battery in the display as usual.  I thought everything was charging good and went shopping for groceries. When I got back I checked on the phone and again it was very warm and still would not turn on. My next step was to try and turn it on and no go. I thought lets see some other things… So I took the phone and charging cord to the computer rather that using the wall plug in.  I allowed the phone to cool down and again I tried to recharge the phone. After cooling I swapped out the new battery with the old and again I tried to recharge and the phone only got hot. I did not stop there I had another idea… Once the phone was cooled down I plugged the phone in without a battery in it at all. The phone once again got very warm like every other time.    Is my phone toast as I cannot get it to work? Looking forward to hearing from you.The phone is not connected to a network. I believe I updated the version once and had issues trying to update again due to a lack of space apparently??? I would like to use it as a MP3 player as I can load memory cards into it. Have a lovely day.

Solution: It looks like the problem is already caused by a faulty power IC or other internal component. If you can perform a factory reset when starting the phone in recovery mode then I suggest that you do so. Take note that this will erase your phone data. If you are unable to access the recovery mode of the phone then you will need to have this checked at a service center.

Galaxy J3 Will Not Charge

Problem: J3 phone wont charge new battery. First try was factory reset of phone. Phone still couldn’t charge battery, so tried the below process: 1.) New battery was charged to 100% using a Samsung charging station (white plastic housing with lockable cover that charges battery apart from phone) 2.) This fully charged battery was placed in phone and used for a few hours total over two to three days. 3.) At around 31% the phone was plugged into its own charger and charged all night with no increase in battery percentage. 4.) Performed soft reset. Phone charged battery to 41%. Charged all night but got no further than 41%. 5.) Charger fits securely, no corrosion or dirt in charger or phone port. The charger able to charge iPad Pro. PC detects phone via USB port. Battery is new and does not spin on table or show bulge.

Solution: The best thing that you can do right now is to clean the charging port of the phone using a can of compressed air then try using a different charging cord to charge the  phone. If this does not work then this is most likely a hardware related problem already most likely caused by a faulty charging port assembly or power IC. The best thing you can do right now it to bring the phone to a service center and have it checked.

Galaxy J3 Bootloop To Snowy White Screen

Problem: I have a Samsung J3 with a snowy white screen when it boots. It turns itself off and that keeps going in that loop. I replaced the lcd but I still have the same problem. The only cause I can think of is, I left it in my car to charge for 20 min. Can’t tell if it can be rebooted or not. Any help would be much appreciated!

Solution: It looks like the problem is already caused by a faulty hardware component. The best thing you can do right now is to try starting the phone in recovery mode and if the screen works in this mode you should do a factory reset as the problem could be caused by a software glitch. Take note that this will erase your phone data. If this does not fix the problem then you will need to bring the phone to a service center and have it checked.
