Manufacturer, Model, Android version?

The screen is supposed to go black when you are on the phone as so your face does not push buttons. as far as it not coming back on try hitting the power/home buttons a few times before doing a battery pull.

Just as a test, try making a call. When it goes black, put it to your ear and take it back away. Does this wake it up? Does it wake back up after someone hangs up? Or does it just turn off and there's no coming back without a reboot?

Did not think about that, if they are not triggering the proximity sensor it might be getting confused.

I have a GS3 (Verizon) and i have never experienced this issue.

As mentioned the black screen is a feature (not a bug). It is used for a couple reasons

1) So you don't hit a button on the screen by accident.

2) Making a phonecall is one of the most taxing things on battery, so the screen being off prevents un-needed drain.

When the screen goes black can you still talk on the phone? Have you tried putting the phone up to your ear and then taking it away while it's black? If you attempt to call the phone (or text it) does it respond?

Check to make sure your screen protector is not blocking the proximity sensor. Happens to a lot of people at my job.

I was just gonna post that. Screen protectors over the proximity sensor is what causes this issue 90% of the time.

My phone is in a case, no screen protector.

Stupid question, but have you tried without a case? I've seen many cases when the latch of the case would trip the proximity sensor (on an iPhone at-least). It's worth a shot.

    • Linux 7.2's first release candidate gets off to a good start

      By zikalify · Posted

      Linux 7.2's first release candidate gets off to a good start by Paul Hill Credit: Larry Ewing It has been a few weeks since the release of Linux 7.1, and in that time, the Linux 7.2 merge window has been open, where developers can submit their features and patches ready for the upcoming release. That window is now shut, and the release candidate phase has begun so that new features can be tested and further fixes applied. According to the founder of Linux, Linus Torvalds, this week’s release candidate looks “reasonably normal”. Although we are super early in the release candidates, this is a good sign as it makes it more likely that an eighth release candidate will not be needed. Torvalds even mentioned that the update’s stats are only larger than they really are because there was another AMD header drop with a third of the patch just being AMD GPU register definitions, which aren’t big changes but make the code contributed look larger overall. In addition to this, he noted that just over half the patch is drivers, even when excluding the AMD register dump. The rest of the changes are spread out over architecture updates, tooling, documentation, and core kernel updates. In the next week, Torvalds says that he will be chilling out, taking the week “mostly off”. Despite this, he will be reading emails and keeping up with things, so if he is slow responding, now you know why. He said he is hoping for a calm week, but we will just have to see if the second release candidate is actually like that. We should expect seven or eight release candidates before Linux 7.2 is released, so expect it around the end of August. If you missed it a few weeks ago, be sure to check out our coverage of Linux 7.1's release.

      Ridiculous claim that the labor cost difference of $6000 annually would increase cost per phone by $200. The employees produce 3 phones per month or what?

      Never used the G7 Pro, but I've never had a good experience with that style of d-pad and fighting games.

      And I just bought a seat cushion for my mesh chair. The chair feels nice but the first time I sat in it with boxers, I realized I don't like the feel of mesh on my legs. 😂
