Let me write few points which never been disclosed by paid media or false review or ignored ?
1. REAL ME 1 SUPPORTS DUAL BAND WIFI- it means 2.5 ghz and 5 ghz is supported
2. REAL ME 2 : SINGLE BAND WIFI is supported - 2.5ghz
3. GOOGLE CHROMECAST : Both of them does not support ( mirror casting / mircast ) if you use google chromecast. It means that you can't get mirror image of your mobile on tv if you use google chromecast. You can chromecast youtube no issues. You can do miracast/...
