 ## Capture screenshot  
 - This feature is only available in **Better xCloud**.  
-- Works on both desktop & mobile, but it's designed for mobile users.  
-- 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.

 ## FAQ
 1. **Will I get banned for using this?**  
-I think it's very unlikely that you'll get banned for using this. Most of the features only affect client-side, except for switching region of streaming server (you'll connect to another server instead of the default one). If you want to be safe just avoid using that. As always, use as your own risk.

-2. **Why is it an Userscript and not extension?**  
+2. **Why is it an Userscript and not an extension?**  
 It's because not many browsers on Android support installing extensions (and not all extensions can be installed).
 
-3. **I see "???" button instead of server's name**  
+3. **I see "???" button instead of the server's name**  
 That means Tampermonkey is not working properly. Please make sure you're using the latest version or switch to a well-known browser.  
 
 4. **Can I use this with the Xbox Android app?**  
-No you can't. You'll have to modify the app.
+No, you can't. You'll have to modify the app.
 
-5. **Will you able to enable "Clarity Boost" feature on non-Edge browsers?**  
-No. "Clarity Boost" feature uses an exclusive API (`Video.msVideoProcessing`) that's only available on Edge browser for desktop at the moment.

 ## User-Agent
-You're no longer needed to change User-Agent since you can just use the **Force high quality stream** setting.  
-If your browser doesn't support **Force high quality stream** setting, try changing User-Agent to:  
-```
-Mozilla/5.0 (SMART-TV; LINUX; Tizen 7.0) AppleWebKit/537.36 (KHTML, like Gecko) 94.0.4606.31/7.0 TV Safari/537.36
-```
-This will change your device to a Samsung TV running Tizen OS. It will improve the stream quality.  
-
----
-Change User-Agent to:
-```
-Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36 Edg/114.0.1823.67
-```
-This will trick xCloud into thinking you're using Edge browser on desktop.
-
-Other options (only do one of these):
-- Add ` smarttv` to switch to Smart TV layout.
-- Add ` Xbox;` to become an Xbox console.
-- Add ` 36102dd3-6953-45f6-8b48-031fb95e0e0d` to become a Logitech G Cloud device.
-- Add ` 0ed22b6f-b61d-41eb-810a-a1ed586a550b` to become a Razer Edge device.
