iOS devices heating up
See original GitHub issueDescription We are using the plugin for scanning barcodes. Usually it is used in warehouses. We noticed that after a couple of minutes the camera and eventually the device itself get heated up and it is very obvious. You can feel it is overheated after five minutes. Although I never experienced it is reported that sometimes it ends up with application crashing.
It is very obvious on iPhone X and iPhone Xr. It is also observable in iPhone SE (2020) devices.
I forked the repo and changed discoverCaptureDevices function only to have builtInWideAngleCamera by changing the line to this:
return AVCaptureDevice.DiscoverySession(deviceTypes: [ .builtInWideAngleCamera ], mediaType: .video, position: .unspecified).devices
from this:
return AVCaptureDevice.DiscoverySession(deviceTypes: [.builtInTripleCamera, .builtInDualCamera, .builtInTelephotoCamera, .builtInTrueDepthCamera, .builtInUltraWideCamera, .builtInDualWideCamera, .builtInWideAngleCamera], mediaType: .video, position: .unspecified).devices
I thought opening triple camera for simple barcode reading may be unnecessary and that is the reason why device was heating up. But it didn’t help.
Our app is a replacement of an old NativeScript app and that app doesn’t have this problem on barcode scanning. I tried some other Cordova/Phonegap plugins. Most of them has this issue except one. We are in no position of switching plugins right now. I wonder if there are any solutions to fix this issue or if I misconfigured something.
Steps to reproduce
- Open the camera
- Leave the device for 5 minutes
- Check the camera with your hand. Observe it is heated up
- Leave for another 10 minutes
- Check the whole device is heated up.

It should yes, you can just add the branch to your
package.jsonand change the calls according to the interfaces (there is no more single-scan function) just astart,pause,resumeandstop.https://github.com/capacitor-community/barcode-scanner/blob/ml-kit/src/definitions.ts
It is not finished, for example checking the permissions aso. is missing, but it should work in general for this testing purpose.
I was now able to merge the android version into the branch, this is a big step for the ml-kit version.
I still needs cleanup and my time is kinda limited at the moment unfortunately, but I will do my best to make progress as fast as possible.
