Samsung Galaxy j7 Prime: Why is my back button not working

Mon, 13 Jun 2022 11:19:36 -0700

What causes some keys not to work sometimes? I discovered the return/back button on my phone wont respond to touch often times. This is frustrating because it makes using an app that requires a return function difficult.

Samsung Galaxy j7 Prime: How do I fix faint lines on screen?

Thu, 19 Jul 2018 13:39:34 -0700

So I have the Samsung Galaxy J7 Prime, and until a week ago had a thick glass screen protector. About a month or two ago I must've dropped it, and the screen protector developed a screen-wide crack. I'm not sure if this added pressure or something to the screen, but within the week the screen began to develop faint white lines that kind of "blurred" the display on the lines. At this time, it wasn't too serious. I could turn the phone off and on again (just a quick tap of the power button, not a complete shut down) or apply gentle pressure over the screen for a minute and it would be fine again. This happened for about a week, and stopped altogether. It began happening about a week ago again, and for the last 5 days it hasn't gone away. There aren't any cracks on the screen itself, it looks normal until you turn it on. It's not completely stopping me from using the screen; it has no effect on me using it and registers all my touches. It's just kind of annoying to look at and would overall look better if it were fixed. I've tried entering "safe mode" to see if it is a virus or something from a third party app, but it still persisted, even after the restart. I'm planning on getting a new phone in a couple months anyway, but I would like to find out what to do to fix this (if at all possible). Thank you in advance for any and all help!

samsung galaxy j7 prime: phone is stuck on samsung logo and is continuously vibrating

Tue, 09 Jan 2018 04:15:54 -0700

Hey guys i need your help, i had left my samsung galaxy j7 prime on ultra power saving mode untill it got to 0% and then i had to pay for something using wechat and it started glitching and then it turned off. So i went back home , put it in the charger and turned it on and it went smoothly till it reached the samsung logo, it kept on doing that dim to bright thing while vibrating a few seconds apart. i tried putting it in recovery mode but it wont fully power off because it has a non removable battery.

Samsung Galaxy j7 Prime: Testing with another device's screen

Thu, 29 Sep 2022 12:18:16 -0700

I got a J7 prime with a completely dead, broken and miserable screen.

Took it apart (not wearing gloves, oops) and seems like the rest of the components is fine.

So I got a spare screen from a J5 prime (which has the same connector), then tried to turn it on from USB power... No success.

Is it correct to deduce that the phone is dead? Or is it simply not compatible with another model's screen?

Samsung Galaxy j7 Prime: How do I fix a burnt charging port?

Thu, 14 Dec 2023 16:22:13 -0700

I recently received a Samsung Galaxy S7 Prime from a friend. He told me that when he plugged it in to charge one time it caught fire on the charging port and he had to use a fire extinguisher to put it out.

I took off the back cover and it has no water damage from the fire extinguisher, but the charging port on the bottom of the phone is extremely burnt out of shape inside of the port and out. The phone is in almost perfect condition externally, so I would really like to fix it. There are no cracks or burns on the screen, and the battery is not swelling.

I have fixed tablets and phones before but I have no idea how to go about fixing this problem, and I don't even know how to open the phone to see the internal damage to the port. I have tried plugging a lightning cord into the phone to try and power it up, but the inside of the port is melted and the plug does not fit all the way in.

How do I open it up to see the damage to the port, and how do I fix the phone? How much will the fix cost? Will I have to replace the logic board, or is the charging port a separate part? Any answers or help is greatly appreciated.

Here is a picture of the port:
