Keep flashlight on while in camera I'm looking to use an old phone (like a Nexus 5 or Honor 5X) as a nighttime security camera with the Manything app, but this doesn't seem practical as I just can't get the flashlight working. 

I plan to use Macrodroid/Tasker to turn the flashlight on automatically at night (as Manything doesn't natively support it), but the problem is that the flashlight turns off when opening the Manything camera view and can not be turned on while using the camera.

Is there a way to keep the flashlight on while using the camera in Manything? Or is there an Android skin which allows the flashlight to be turned on while the rear flashcamera is active?
This seems like a device specific issue. Some phones will allow the flashlight to be on while the camera is on, others won't.

The phone I'm using, Galaxy S5 has no issue with the flashlight that comes preinstalled, being on while the camera is running.

So if you're anyway buying a phone for this, Galaxy s5 or any other phone that allows it, should be your choice. (In my humble opinion, instead of buying this phone, you're better off buying a security camera with night vision...)

In the screenshot below, I have the manything app in recording mode, and the flashlight on, and I'm facing a mirror.

Note: other flashlight apps didn't work while camera is on.

I wouldn't post this as an answer had there not been a comment from OP saying:

  purpose :). Could you help me make sure I get one that'll let me use
  the flash like you can?
