The good people over at XDA Developers didn’t wait for Asus to officially open up the feature, however, and has listed down the steps to enable EIS for videos on the Asus Zenfone Max Pro M1. XDA member ronello outlined the steps to enable EIS in the Zenfone Max Pro M1. It’s quite easy and if you follow the steps, you’ll have the feature in no time. 1.
Open the camera application. 2. Go to Settings 3. Search for “Redeye Reductions” and tap on it until there’s a popup saying you’re in “camera developer mode”. 4. Go to Video mode 5. Set the resolution of videos to anything less than 4K. 1080p will also do. 6. Toggle the “Image Stabilisation” option in the settings.
The instructions are easy enough, and we managed to enable the feature in the review unit that we received. The videos do look a little less shaky after enabling EIS. Users on XDA’s forum are also reporting the same. However, it’s still unclear as to why Asus has not enabled the feature officially in the camera app. The company could push out an update in the future to enable it. You can also install the Google Camera app without requiring root access.
The instructions are there on XDA and it's pretty easy to follow. The phone apparently has a hidden fastboot command to enable Camera2 API without modifying the system files. The Asus Zenfone Max Pro M1 variant with 3/4GB RAM variant sports a 13+5MP camera on the back with f/2.2 aperture primary lens and f/2.4 aperture secondary lens. The secondary lens is used for depth sensing. The 6GB RAM variant sports an upgraded 16+5MP camera with f/2.0 aperture primary lens.
