 Don't see your browser in the table? If it supports Tampermonkey/Userscript then the answer is likely **"YES"**.

-<sup>3</sup> NOT RECOMMENDED at the moment since its Userscript implementation is not working properly (see https://github.com/redphx/better-xcloud/issues/5 for full details). It's still my favorite app to play xCloud on because it's lightweight, supports Userscript (premium features, only $1.99) without having to install anything else. I built **Better xCloud** just so I could use it with Hermit.

+- **Kiwi Browser** is the best choice on Android. All features work, it means you can get 1080p stream + high quality codec profile (the best possible quality).  
+- **Better xCloud** also works on Android TV, but you'll have to sideload the browser APK and need a bluetooth mouse if you want to interact with the Settings.

+## Capture screenshot  
+- This feature is only available in **Better xCloud**.  
+- Works on both desktop & mobile, but it's designed for mobile users.
+- It's client-side only.
+- It captures the current frame of the stream and save to a file. That means you won't get the raw quality like when you play on console, but it's still better than using the built-in screenshot feature on your phone.  
+- Screenshot's resolution & quality depend on the quality of the stream at the moment.  
+- Screenshot doesn't include touch UI, notification bar... only the gameplay.  
+- There might be a slight delay.  
+- ⚠️ It's not possible to map the Share/Screenshot button on your controller to this feature.  
+
+### How to capture screenshot  
+1. Enable this feature in setting.
+2. Play a game.
+3. Tap once at the bottom left/right (depend on your setting) to show the Screenshot button.
+4. Tap on that button to capture screenshot.
+5. Screenshot will be saved by browser.
+6. You can double tap that corner to capture screenshot.
