My phone has recentrly updated but i have experienced some problems with the camera app. The first time I use it, it works fine but after that, it gives me an error message that says "unable to start camera. Reboot the cellphone". I have done software reparation with sony tools but it keeps failing. I hope sony fix this problem soon.
After rebooting the smartphone for a long time does not see the flash drive and memory, you must wait 15 minutes. Then open the gallery with photos, wait until all photos are loaded for viewing. After waiting another 10 minutes. And the camera will be able to earn normally. This all happens after a reboot. Immediately you can not start the camera, it gives an error.
Sony is watching you. If you do not want Sony employees to remotely change the settings of your XZ1 smartphone - you need in the settings, application section, find support - disable changing the system settings. Next - disable mobile data transfer in the background.
