One of the really cool things you can do with your Galaxy S3 is mirroring the screen to your television. While this obviously lets you watch movies or stream NetFlix, it will also allow you to play your HD games on a big screen, or view your photos. All you need is your phone, and a wireless capable Samsung Smart TV, 2012 model or later. I don't have one, don't worry, we'll show you another method in the second section of this guide.

How do I set this up with my phone and computer?
I have a Samsung Galaxy S3 and a new Dell Laptop.
Please refer to the above question and advice so that you can find the solution to your issue at hand.
To use screen mirroring on your computer, you will need to purchase the AllShare Cast Dongle. It can be found for relatively cheap on Amazon or at other various retailers. The only requirement is that your computer has an HDMI port, which most new computers do. Once the AllShare dongle is connected to the computer and powered on, it will show as an available device in the menu on your phone.
To reach this option follow these steps.
1. From home screen go to the menu
2. Next, go to settings option, may need to select "More settings" as well after the first menu.
3. Next, go to Wireless and Networks.
4. Select AllShare Cast.
5. The phone will scan for available devices.
6. Now the AllShare Cast Dongle should be available, select it and you should be able to see the screen.===My Samsung Galaxy 3 says can't connect because of a hardware issue?=== This is when I AllShare - pin accepted but the share won't start because hardware issue
If it says hardware issue, you would need to go back to your phone seller and have it checked. It may also refer to the problem with the hardware that you use for connection. Hardware pertains to the problem with the device, either with your TV or your phone. It most often happens that it's the TV that has some problem.
You should try trouble shooting the hardware, or the connection between your computer and TV. Then, try to update the current version of your application. Can you add some more details about the hardware you are encountering?
A hardware issue can range from damage being doe to the external or internal parts of your device. Try to uninstall AllShare from your device and restart the whole process.
If your TV is not a Samsung smart TV, then it is possible that the phone will not detect the TV. Even if it does detect it, it may not transfer properly. In order to ensure the screen mirroring will transfer properly you will need to purchase the AllShare Cast Wireless Hub. Just hook it up to the TV's HDMI input. This hub will act as an antenna to transfer the wireless video to the TV. Just simply plug it in and power it on. Your phone should now detect the TV as an available device and transfer properly.
What if the device is not being detected?
If the phone is not being detected when you scan for available share from phone to TV. You can simply power cycle the television or the phone itself. Once you power cycle the whole devices, power them back and do the same steps on how you tried to sync the phone with all share. Make sure also that the devices are connected to the same router or WiFi internet at home to easily connect them to all share or pushing the images to mirror on your big screen.
Normally, restarting your devices can help you refresh the system and connections as well.
How do you control it from timing out?
Work's for about three minutes then shuts down? Galaxy 3
I believe that you are referring to the screen timeout option which is on your device. You can change up the timeout by performing the following steps below:
1. Go to your settings
2. Underneath the my device tab tap on display
3. Tap on screen timeout
4. Choose the selection that best fits your time so that you will be able to adjust this timing
Here below is a video you can refer to about this matter:
Hi Ghemgc, I was just curious when my phone, S4, decided to update the allcast dongle and asked if I wish to turn on screen mirror. I don't have a dongle but I do have a Samsung Smart TV. Anyway, I turned on the TV and it scanned but never found any devices so I assume my TV is a little too old. Thanks for being so considerate in any case?
Sharecast Dongle - Galaxy S4 - Samsung Smart TV but several years old - tried turning set on and scanning but phone didn't find device so I figure the TV is a little dated. I have Chromecast and it works fine. I guess I'd have to buy a dongle if I wanted to mirror to TV?
It is possible that your TV does not have the said feature because you have said that it is a bit outdated. You could try and buy a dongle for it but ask them if it is compatible for your TV and phone before buying it.
Samsung G3 screen dead, help getting SMS off it?
Hi, I dropped my phone today and the screen is dead. Wondering if there is any way to get the SMS of it. I have it plugged into the PC, and have backed everything up using Kies, but the SMS are saved in an .sme file that I can't open. Other software won't work without debugging enabled, or installing an app on the phone, which I obviously can't do. Next resort is sharing the phone's screen with the PC via USB - possible?
