Samsung Galaxy J2: Samsung Galaxy J2 won't turn on after checking battery and charger

Thu, 14 May 2026 22:39:20 -0700

My Samsung Galaxy J2 turned off unexpectedly and will not turn on again. I have already tried the following troubleshooting steps:

1. Checked with a different charger and cable.

2. Tried a different battery, but the phone still shows no signs of life (no lights, no vibration, and no display).

3. Cleaned the battery terminals and the charging port.

4. Attempted a soft reset (Power + Volume Down) and tried to enter Recovery Mode (Power + Home + Volume Up), but there is no response.

5. Called the phone while it was plugged in, but there was no ring or vibration, suggesting it is not just a display issue.

What could be the next steps to diagnose if this is a motherboard issue or a faulty power IC? Any help would be appreciated.

Samsung Galaxy J7: Ive dropped my phone in water, everything works but the on/off button

Sun, 19 Apr 2026 12:53:58 -0700

I dropped my phone in water and immediately took steps to dry it, after a small amount of time, I powered it back on and everything seemed to work except the power button. I can still turn it on because of the home button but it only turns off on time-out. Looking for a solution to this problem. Any help is appreciated.

Thank You

Samsung Galaxy J5 (2016): Why my wifi network speed is slow on Samsung Galaxy J5?

Thu, 12 Mar 2026 05:47:44 -0700

My samsung galaxy J5 has a problem with wifi. My connection is 30 Mbps. But i am getting only 4 Mbps on the device(speedtested). All other wireless devices are working fine on 2.4ghz but only the J5 has this problem. I wiped cache partition and also reset the device couple of times. I have tried changing router channels and resetting the router also. My router is tplink archer c60 ac 1350Mbps dual band. The J5 only supports 2.4 ghz band.

Samsung galaxy J5 Prime: J5 Prime Phone will not turn on

Tue, 25 Nov 2025 00:59:09 -0700

So I've had a Samsung J5 Prime for just over 5 months now, and this is the first time it's ever acted up. I didn't charge it over the night, (I forgot) but charged it when i woke up and it was around 60% before I went to school. After about 4 hours of working fine, I went to check the time and my phone wouldn't turn on at all. Held down the power button etc and naturally assumed it had run out of battery. I remember it had about 40% charge left which I thought was a little strange, but I came home and plugged it in.

I've left it charging for about an hour and a half now, but nothing has happened, no red light, no response.

Yes, I checked if the charger was turned on.

I've tried holding down the power button while it's charging

I've tried switching power plugs and chargers

No idea what to do......

Also, the back cover doesn't come off so i cant take out the battery etc.
