Samsung galaxy core prime: How do I fix Horizontal lines on my screen?

Sat, 02 Dec 2023 14:17:58 -0700

My phone is showing thin black horizontal lines on the screen, so it looks a bit like the screen of 1980s television. It covers the entire phone, and it happened a few days after the screen protector on the top right corner of the phone cracked. Otherwise, the phone still looks fine. It wasn't that bad at first, the screen just looked like the display was only showing every other line, but when i accidentally put pressure on the top right corner of the phone (where the screen protector cracked), it got worse and started looking like how I explained it above.

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.

Blu Studio HD 6.0: Why is my Blu Studio not charging?

Wed, 19 Jul 2023 11:21:49 -0700

Earlier today I tried charging my Blu Studio 6.0 on my computer using the charger cord. The phone was off as I did this.

After a few minutes, I tried turning on the phone. It turned on and I left it alone overnight. When I unplugged the cord from the computer the next morning and tried turning on the phone again. It didn't turn on.

I tried charging the phone using a wall outlet for an hour, and I got the same reaction. It would turn on when it was plugged in but would die when removed from a power source.

Alcatel One Touch Fierce: Why is my power button intermittent?

Mon, 08 Apr 2024 23:28:22 -0700

The power button on my son's phone only works with many attempts to turn it on from the "sleep" mode. If someone calls in the phone will wake. Sometimes he is not able to wake it up at all. I saw one answer on your site for pressing the power button with the -volume button to re-boot another android type phone. Should I try this or is this problem more of a mechanical button problem? Thanks for any help...don't think he can afford to buy a new phone.

Sony Xperia Z Ultra: Sleep of Death -Power button Display Issues

Tue, 13 Nov 2018 16:18:05 -0700

Support,

I bought a Sony Xperia Z Ultra phone on 9th August through Flipkart (online stores) In India, and upgraded to build number- 14.1.B.1.510 on 30th August. After this upgrade the phone display started going on and off every 10 seconds. Then I power it off, since then I could not restart the phone. The phone is dead!

I have pressed the power botton many times, but it was not fruitful.

The battery was 100%, still I put it on charging, but it is not showing any charge light. I tried to connect to my computer, that too doesnt work.

Is there any way I can power this phone ON again?

I m in Lagos, Nigeria. I have contacted Sony centre, but they confirmed there is no Xperia service centre here.

please help!
