I need to take a photo of my electricity meter reading. My electric meter is situated under the staircase. i.e. in a dark place. I can switch the light on under the stairs but it doesn’t illuminate the electric meter. So, if i switch the torch on my phone on and then the camera on or switch the camera on then the torch on my phone on, my phone torch switches off and i get the message can’t turn on torch because the light is being used by another app. This is driving me mad. I’ve tried Google which either suggests powering the phone off then turn back on, which doesn’t resolve the problem, or that an app is using the camera and to delete each app using the camera until you find the app causing a problem. e.g Snapchat, which i don’t have. I would be very grateful for any help.
My phone is a Samsung S10 5G.
