Hey. I have updated my Huawei P8 Lite and now its my front cam gone wild. the rear cam is working properly but whenever i shift to the front cam a message pops up "unable to start the camera, check if there are third party applications running in the background such as a flashlight. close them and try again". I reboted my phone, reset the cache and even factry restored it but this is not working. kidnly help me with this.
