This has happened to me way more times than I care to mention. The latest Yunteng YT-1288 Bluetooth Selfie Stick (and many other bluetooth as well as wired selfie sticks) just does not take a picture on my old Android Phone. Pressing the shutter / camera button on the bluetooth remote changes the sound volume level. Other buttons such as Zoom + or – buttons also change the sound volume level instead of actually taking a picture or changing camera settings. How do we resolve the situation?
The Internet recommends that we go to Camera Settings > Volume Buttons setting and change the action to Shutter. Unfortunately, this entire setting is missing from the camera app on some of my phones and present on other. Turns out, this is most predominant on the default Android Camera App that comes bundled with Android 4.x and 5.x. On these phones, pressing the camera button on your wired or wireless selfie stick triggers the sound volume. The camera actually ignores the selfie stick button action completely and it does not have any provision to change the settings either.
The default camera app bundled with Android 6.x and 7.x seems to be have built-in support for external camera triggers and the selfie sticks work just fine.
However, on your old phone, if you were to try out some other Camera App that supports an external shutter button action, the same selfie stick will work just fine on your phone. A number of apps were suggested such as Open Camera but these apps are complex and not meant for the basic user. Google itself has issued an app called the Google Camera and it works just fine with a selfie stick.
Unfortunately, Google Camera app appears to be restricted and it is not available for download form Play Store (at-least not in India). Fortunately, you can use a service like APKPure.com to download and transfer the APK file to your phone and install the app by allowing installation of apps from “Unknown Sources“. Let me know in the comments if this article helped you start using the selfie stick with your phone.
