Samsung Galaxy S7: Why does my screen go black when the phone is too cold?

Sat, 17 Dec 2022 14:53:54 -0700

This started back in November, My phone would get too cold and would have a flickering screen. I tried many factory resets but no such luck. I switched to another phone for a while but am back to the S7. If the phone temperature is too cold the phone screen goes completely black and I can’t see. I literally have to place my phone a heater in order for the screen to light back up. Everything else is still functional I just can see what I am doing when the phones internal temperature is too cold. (was in the 60’s this week and it still was too cold or the screen to work)

What can I replace for this to work?

Samsung Galaxy S7: Abnormal Factory Reset- Cannot Connect to Wifi to Login

Tue, 29 Aug 2023 08:48:55 -0700

My LCD stopped working and needed to be replaced. Before I knew what the problem was a tried a soft reset. I could hear my phone ring, it would vibrate, it would light up. Anyway, after LCD was replaced, turned the phone back on it takes me through the start up Welcome screen. I choose my language and it takes me to a screen that says set up wifi. Then I get the message

" Due to an abnormal reset, the selected Wi-Fi network cannot be used. Connect to a different wi-fi network. "

No matter what wifi network I try to connect to, I get the same message. If I click the skip button it says

"Due to an abnormal factory reset, you will not be able to use this phone until you sign into your Google Account to confirm that it belongs to you. A network connection is required."

I have the google account information, however, I can't get to the sign in screen because it's not allowing me to connect to any network.

Additional information

1. I initially had Verizon with this account. I no longer live in the US so I don't have Verizon anymore.

2. I tried to sign in without a sim card, with a sim card from my current country, with a Verizon sim card from another phone that is currently activated - I get the same message with all.

HELP?!

Samsung Galaxy S7: Why can I not place calls?

Mon, 03 Feb 2025 12:19:35 -0700

My Samsung Galaxy S7 recently stopped being able to place calls. I can still recieve calls, send and recieve messages and use data. The only this that is not working is outgoing calls. When I attempt to make a call the phone says "dialing" and the after a few seconds, it says call ended and hangs up without ever connecting the call.

If restart my phone in safe-mode and clear the cache, I can make one call successfully but then it stops working again.

I would guess that the problem would be resolved by factory resetting my device, but Iam still holding out hope that it wont come to that.

Thanks.

Samsung Galaxy S7: Flashlight flashes when plugged in, device does not power up.

Tue, 13 Aug 2024 00:49:45 -0700

I have a customers Galaxy S7 that doesn't power up or indicate charging.

The device however flashes the flashlight repeatedly when plugged into charger.

Was hoping to see if anyone else has ran into this problem, and if possibly the battery or charging port are bad? (Haven't tested new since I don't usually stock these items)

Seems like the flashlight flashing is an indication of something, just looking to see what it is indicating!

Thank you!

Samsung Galaxy S7: Need help removing the back cover

Thu, 21 Mar 2019 11:26:11 -0700

My camera lens is shattered. I ordered the replacement lens and adhesive from ifixit, and i also ordered a suction cup tool to pry it open. At first I was using a hair dryer for heat. It wasn't working. I then tried putting my phone on a pan on the oven set to the lowest setting. The back cover still won't budge at all. What am I doing wrong? Do I simply need more heat? Anything else I can be doing? How hot is it supposed to get??

Any help would be much appreciated.

Hi ! I got a Galaxy S7 (SM-G930F) and when i was using my phone, it told me that an update was available. I did agree to install it, and then my phone downloaded it and rebooted. But during the update, i got an error message at 32%, (see attached picture)

Samsung Galaxy S7: Dented battery. Safe or not safe?

Mon, 21 Nov 2022 13:33:09 -0700

Hello everyone, I ordered a replacement battery from Ifixit 3 days ago and just received it. Well unfortunately when I opened the package it's evident the battery has a dent in one of it's corners.

Now I'm not very familiar with lithium ion batteries and all the searching I've done people either say it's fine as long as it's not punctured while others say it's better to play it safe than sorry. So I'm looking for any advice, I'll attach pictures to better illustrate my problem.

Samsung Galaxy S7: After dropping Samsung Galaxy S7 screen is black

Sat, 18 Dec 2021 07:32:17 -0700

Hi,

I have Samsung Galaxy S7 SM-G930F phone which has been dropped and has a cracked outer glass (at least it seems it is just the glass but not the LCD). It is still recognized by the computer and top LED and bottom buttons are lit except that the screen is totally black. I thought it is firmware issue so I tried all those combinations to hard reset it , get into recovery mode etc. I even tried to flash stock firmware. But it still remains black. So my question is what are the chances that the actual LCD panel is damaged. But I have never seen a damaged LCD which does not show any signs and just stays black. Usually it shows something even though it is cracked. Thank you in advance.

Thu, 28 Feb 2019 20:20:09 -0700

My S7's screen glitched out and stopped working. I have a replacement phone, but would really like to transfer the data from the old one.

Ideally, I'm looking for a way to remote control the phone's screen from my PC, but I need to get to that point without accessing the phone directly.

If anyone has any tips they would be much appreciated.
