I have spent a frustrating 8 hours trying to screen mirror from my Roku Streaming Stick to my Samsung 7 phone. Turned Roku Systems Screen Mirror Mode to Prompt and in Screen Mirror Devices none show now. Problem is phone. Even if Smart View App added worthless to set up now since SAMSUNG IS ELIMINATING IT AS OF OCTOBER. Samsung is trying to force phone users to receive streaming through its Smart part of TV because most people do not, chosing to use a Firestick or Roku – Samsung is trying to force people to use its Smart Things app – I do NOT want to nor do most people – Besides not wanting to be forced to give permissions to it I do not want to (I do NOT want to give it access to my files, media etc. since I do NOT want to share them by screen mirroring – just videos I watch through chrome. Even if you do agree to all the permissions it requires you to add your Samsung TV. I do NOT want all my devices connected all the time. Only other screen mirror setting on phone is for car. Regarding using Wifi Direct? I can turn it on through the Share option when I am looking at the page/video I want to mirror but cannot figure out how to turn on in Roku. I think the Roku remote I have uses it . (And I read an article about latest update to Roku stick potentially causing interference that instructed me to turn off some Roku channel connection that is an option I do not have). (And there is the potential hacking problem when using Wifi Direct due to poor security built into devices you connect – so due to that article guess possible my phone could be hacked if connected this way but no more info given – says can use hack into a single device to gain access to all devices on network – so dismayed to learn that later Roku remotes use Wifi Direct to connect to the Roku – potential for hacking by all Roku users with latest remote? But matter for another article from you – did learn from article that my HP printer has all this time by default had Wifi Direct turned on, which could have enabled hacking into my phone or PC- thanks HP). But getting back to the screen mirroring, so you would think Roku would be really concerned about this, since if you only have three HDMI ports and use one for cable and second for another purpose, you are going to have to choose between a Roku and Chromecast device since it is a Google device and you can download the Google Home app – or read second easier way can do through phone setting but cannot find article again so would be great if you included that info in an update article you hopefully decide to write since the elimination of Smart View App and Smart Things App that does not allow connection to Roku is going to distress a lot of people who use it Smart View now on their phones. Since the only Android device I have is phone I might not mind using the Google Home app but it will probably require permissions to things I do not it to have as well. Well due to the pandemic, Roku has decided NOT to offer any phone support. Or even chat. Its FAQs has NOTHING that notes the upcoming change. No Roku exec seems to recognize that Samsung is trying to keep its phone users from screen mirroring to Roku. Is it because company being acquired? Perhaps there is an app that makes the Samsung phone mirror to the TV. YOUR RECOMMENDATIONS WOULD BE MUCH VALUED BY YOUR READERS. But I want the option to NOT give if access to my files and media. I understand that if I want to show my own photos and videos or a presentation I prepared, that permission would have to be turned on. But if I just want to screen mirror a video I am watching through Chrome that is not on youtube or a channel on my Roku (which is something that has become a major source of entertainment since the pandemic began) what permissions really need to be turned on? And casting is not disclosed anywhere for Android to Roku and think read miracast not great although it cast can still use phone for other things while using remote to control what is being cast to TV screen from phone. any insight on how to vast from phone to TV would also be valuable in an update article by you. Many of us weary of being the casualties of the Microsoft Amazon Apple Google Samsung war for control over all your devices, data, and software, and their making it as difficult as possible to use tech and software from different competitors. Many people are going to be frantic when their Show software no longer works! An article by you now with the answers will be widely read. Thank you for reading this and hopefully posting the answers!!!
