Wed, 18 Aug 2021 23:54:46 -0700

White/grayish line appear across my screen and one or two smaller dots around it. Its very visible when you are on a app with a dark background, such as my home screen or google. When on a white screen such as the interface of ifixit, you can't really see it.

Samsung Galaxy A7 2018: CPU damaged and unable to recover data on it

Mon, 23 Oct 2023 00:26:10 -0700

Hi my phone suffered severe water damage while camping and sitting in a pool of water for an unknown length of time. As I pulled it out of the water I instinctively pressed the home button and it worked but then when I looked at it again it wouldn't turn on. My partner opened it up, dryed it out and removed the corrosion he could see but it still wouldn’t power on or even attempt to charge. He used a current meter and it was short circuiting badly. We had no choice but to send it to a data recovery company as we didn't have the tools and know how to proceed any further. On assessment we were told that the CPU had been floated and needed reballing. They did this and cleaned it up properly under the caps but unfortunately my phone still wouldnt switch on and they said because of this they wouldn't be able to recover my photos and videos. I received this update:

‘The Phone attempts to charge but no APS_HOLD signal coming from CPU'

I know that with a damaged CPU and my phone unable to power up I won't be able to recover my media files due to encryption but I was wondering if there is the possibility of my phone's CPU being fixed and if anyone can point me to a company that might be able to help me. Thank you in advance.

Samsung Galaxy A7 2018: Screen goes black after locking the phone and won't turn back on.

Thu, 07 Jul 2022 13:00:23 -0700

So, I replaced the screen on my phone and it work when I powered it on.

But after i pressed the lock button the screen went black and it won't turn back on again. The only way for the screen to turn on is to force reboot the phone.But then the same problem , screen goes black if phone locks. Even with the screen black the phones works(I can hear notifications).

The exact same problem happened with an Iphone 5s I had..

Could it be a faulty screen?
