编辑：我正在使用最新操作系统的三星Galaxy 7。而且我指的是内置的相机应用程序。 （如果有更好的替代方案，我很乐意听到它。我已经看到了几个但没有什么似乎足够令人兴奋的东西的审查。）
I am trying to use my camera to record some videos. I have it set up on the tripod and then go and set up whatever I'm shooting and after 2 minutes, the camera always exits and goes back to the launcher screen. So I have to restart the camera again, and then re-do whatever settings I had (like zoom in again). Is there a way to have the camera app just stay open without automatically closing? Thanks.
Edit: I'm using a Samsung Galaxy 7 with the latest OS. And I'm referring to the built-in camera app. (If there's a better alternative, I'd be glad to hear it. I've seen reviews of several but nothing that seemed compelling enough to try.)
As an alternative to this answer from beeshyams, if you cannot afford to replace your preferred camera app than try screen pinning that app.
You can pin an app's screen to keep it in view until you unpin it.
For example, you can pin an app and hand your phone to a friend. With the screen pinned, your friend can use only that app. To use your other apps again, you can unpin the screen.
Alternatively, you can use a kiosk-mode app from Play Store to temporarily restrict usage of the device to your camera app.
Thanks to Izzy's list of camera apps
Open Camera is an excellent ad - free (FOSS), open source camera app which has a timer that can be set from upto 5 minute delay for both camera and video. And it has voice command activation too !
Other features quoting Izzy
Developer is Almalence, known from a set of high quality camera apps (a specialist in this area) which are also available in "free trials" and paid versions on the Playstore.
The "full program" would be A Better Camera, which combines his Night Camera, HDR Camera and more ( you can read in reviews and tutorials on Izzy's description )
This app is available at huge discount now !
Tested it and this should solve your problem. Of course, you can try other apps on that list as well
