I'm using Galaxy S10, my phone recently has a problem which when I use some Apps like Camera or snapchat.. the App will shut and open again.. for example when I use the Camera, suddenly it will shut and Home screen will show for a second and Camera will resume working again !!!
Try restarting your phone. may be you have installed an app with unknown source. which includes viruses. If restarting phone doesn't solve your problem. try clear data and cache for camera app
my phone is auto restarting on Daily basis. and I dont install apps from anywhere else but Play store. I will try clearing camera cache and date and force stop it.
Please make sure to clear the camera cashe and data. But if you still face the same issue, then we suggest you visit the nearest Samsung service center with the device to have it checked. 😊
