[Q] Screen mirroring doesn't work?

Hello there,
I've tried on 2 tv's (Panasonic and Philips) and with one WiFi Display bought from ebay, and on all of them same problem. It connects then immediately disconnects with this error. Is something that should I do? I have a stock 4.4.4 rooted ROM.
Thank you.

Do you have an unlocked bootloader?
Sent from my D5503 using xda premium

No. I have the latest stock firmware with root and dual recovery.

i had problems with my lg tv too, but after like 5 times trying it simply worked...
there are several reasons why you cant conect to the tv, must check one by one

Trust me I've tried many many times , doesn't work. I mean it works, shows connected on the tv but after one flash of a second, bum, disconnected with that message. I've read on other devices that it might be because of the recovery or root, but I don't want to go that far with making the screen mirroring work.

did u unlock the bootloader? DRM keys if missing can do that

No. Locked bootloader. Latest stock firmware with root and dual recovery. That's it. Is yours working in screen mirroring?

Screen mirroring works on my Lg TV but it was lagging sometimes even for some 720p videos. So it's kind of working. Sadly don't know why this is happening.

Yea the same thing happening with my lg smart tv too
lag is ok but after sometimes it totally freeze and need to reconnect again
I'm really frustrated with this problem
Questions:
1.Is it hardware or software problem?
2.if it's a software problem then why sony isn't fixing this??
3.lastly is it happening only for z1c or other sony z series phones too???

The phone was bought in September from Vodafone then, a month ago bought by from the person who bought it brand new, so I'm 100% sure that it has a locked bootloader and it had never been unlocked. But just to be sure, how to check this? BTW my previous phone Xperia Z had sort of the same problem, screen mirroring wasn't working, no errors, just not connecting to the devices and that phone was bought by me brand new.

Sounds like DRM issue to me, I have a W9 and can't connect because I lost my keys, but given the glitchiness in operation it's not that much of a loss, I can still Throw to the TV though. Try THIS.

if u have a recovery installed then make a nandroid backup nd do a clean install of latest firmware via flashtool
see if miracast working or not

I have used mine with the Belkin Miracast dongle, so the software isn't completely broken.
(stock 157, no root, bootloader locked)

No, there is a lag. It doesn't bother me because I am just watching basketball and don't look at the phone screen.

I have not got it working with my dongle either. A cheap miracast device.
The reason is probably the missing encryption functionality on those noname devices.
My dongle works just fine with another Android tablet. But not with Sony device. Some companies are just more concerned about piracy issues. Especially if they sell some media themselves...
I would call it a partially supported protocol implementation. On both ends. And there is no information about that when you buy it. But there is a plenty of advertisement on the function as such.

My z1 c has no problem with screen mirroring with samsung smarty tv, using it for two months no problem till today, but it is impossible to play games because tv shows every thing 2-3 second late. But screen mirroring is not that good for z1c's hd resolution because in fhd tv color looks totally washed out. I love throw feature more than screen mirroring. And one more thing i prefer i media share than sony's conventional through option because i can lock while.using i media share.
One problem z1c has that when we lock screen while using media server setting connection disconnects after some time same goes with throw.

[Q] Easiest way to screen share

I am looking to set up a Tab S for my mother-in-law such that she can easily mirror the screen on a monitor/TV and use both a keyboard and a mouse via bluetooth so it becomes an easy to use desktop replacement.
If I use the Samsung HDMI cable, even with the power adapter plugged in, it does not simultaneously charge the device. Samsung have confirmed this.
I am therefore thinking of using sharecast/Samsung link or whatever it is called now. However, there is no way she's going to hunt around in settings to mirror the screen, so what would be the easiest way for her to place the tablet by the bug screen, automatically connect with the BT keyboard and mouse, AND mirror the screen to a Samsung smart TV?
I think the bluetooth should be automatic once the devices are paired? But I don't know how to do the screen mirroring in a VERY easy way!
Any suggestions much appreciated!!! I need the brownie-points with my mother-in-law!
Cheers!

You could try chromecast it is very easy to do:
Open the app
Open the menu pick cast screen
Tap a button and your done.
However it may or may not have the best functionality for what she wants or needs to do. For $35 it is a worth while investment to test if this will work out the best. It will allow charging while in use, you can use bluetooth accessories at the same time, and it is simple to setup even for the technology illiterate. However it is reliant on a good home wifi signal and even then there will be some screen lag using it as a wireless hdmi cable.
Also just remember that a tablet even a microsoft tablet is not really a desktop replacement and some concessions will need to be made if you want to use it as such.

I use a cheap mirrorcast dongle. To use... press the screen mirroring toggle in the notification panel, obviously tv has to be changed to correct hdmi input aswell.

Thanks for the fast reply! Does screen cast work with the Chromecast dongle and using the Tab S? I've read reports (maybe old) that it doesn't?

Yes - I considered this option too, but not all miracast dongles seem to be created equal! Which one did you use and was this casting from a Tab S?
Thanks for sharing your experience.

Yes, I have used it myself from the time I got my tab S (December 24) till a few days ago and it worked for me each time.

Just a cheap ezcast from ebay... all the guts of these are basically the same... and yes this was with tab s 8.4... miracast functionality is built into tab s so you don't have to use 3rd party apps. It works well enough for me to use net flix however not good enough for gaming...for general tablet use it works well.

Disable Sleep Mode On Fire TV Stick?

Hi,
I wondered if anyone could help me, Im trying to disable the 30 min sleep on my Fire TV stick as I need it to remain on a webpage 24hrs as a communication tool. I tried used the dolphin browser with the auto refresh but it crashes and I cant root the stick. I tried a stay awake app too which didn't work either, any help would be greatly appreciated.
Thanks
KoKee

Have you tried Tasker? That maybe able to do this for you? If it's not possible it maybe because you need root to stop the timeout? & root isn't possible via the fire stick

There is a trial version in the play store but if you have a rooted phone,tablet or what ever just buy it, it was one of the first apps I bought & have used it for years & is so useful, a little hard to use at first but well worth learning how to use it.

You are right i posted a bit quick. But i have found that it will not sleep with certain apps for instance i played a hour long you tube mix of music and it never went to sleep but when i play a normal music app its sleeps.

Have any of you guys been able to find a fix? i couldn't even use tasker as it wanted me to hit the + button but due to the limited functionality of the remote control which accompanies the fire stick, i cant even get down to it. is there anyway to prevent the fire tv stick from sleeping ? as i need it to display a website, constantly

Not sure if this works on FTV stick and/or non-rooted, need to be tested. It works on FTV2 rooted (don't have a stick to test).

No, one version back, I think. Mine is at 5.0.5 (537174420), pre-rooted RBox.

Any updates on this (2018) ?

I'd like to share my work-around as of 2018. I install "Stay Alive" app on my fire stick and open it. After you open it, it will keep the screen awake. Keep in mind that it's a third party app, so you have to sideload it, it should be quite easy to google for a tutorial on how to sideload apps onto fire tv stick.
There are many other apps in the play store that claim to keep the screen alive, but in most of them it takes quite some navigation to set them up and navigation within third-party apps can be tricky using fire tv remote or app. Fortunately, Stay Alive has the right settings (keeping the screen alive forever) enabled by default, so just opening it does the job!

Simple TV Display (No Sleep Webpage TV) - an app that helps solves the the original post. Lets you put in a webpage, set how often you want to refresh, and then shows the webpage while keeping it the screen awake

Use a program called Stay Alive! It will appear not to work and complain about google play services not being installed, but my launcher is always open after I turn my tv on in the morning now, with CEC enabled too.

Screen mirroring issues

Hi, guys! !! I'm experiencing some issues concerning the screen mirroring function in my s4 mini. I manage to connect it to my LG smartv and my chromecast 2, Which is attached to my regular TV. But after a few minutes, the image in my TV gets blurry and the connection fails. I contacted Samsung and they made me perform a series of tests,all of Which amounted to nothing in the end. Then , they said I Would have to do a factory reset. First of all, I'm a little weary about this, couse if it does not work, I'll have done a lot of work for nothing. What should I do?? Is it a hardware problem? I'm counting on you guys!!

Using "caffine" to keep your device awake, might be a work around. (turn it on in the quick settings pull down menu, tap to set time, or for more control get the app of the same name on Play store)
Or try testing it with another casting app from play store that might keep the device from sleeping.

Thanks for Your reply! !! Unfortunately, I dont think thats the problem. While the Screen mirroring function is on, my s4 mini Screen is fully awake. The transmission then starts to falter. The images on my TV Screen (and my s4 screen)gets blurry and freezes. Then the connection breaks. ..but i'll install caffeine anyway. ..any Other suggestion?

oh I see. Maybe it's more like the modem/router being overloaded? Or wifi channel interference?

I dont think so. I turned off the wifi of all my other devices and the problem persisted, so its not overload. And I dont think its wifi interference either, because all my other devices can mirror the screen Just fine. All these tests Ive already performed, following sumsungs support instructions. They suggested a factory reset. Do You think That could work?

strange problem. What version of Android? Stock? Are you using inbuilt casting like in CM13? Or Have you tried another casting app? I could only get mine going with allcast app from Cyanogen (or was it Google?)
Factory reset might fix it, I have no idea, but it's a last resort for me!

No it's not available in safe mode, I have lg g5 with Android version 7.0 cast screen works perfectly fine on that. But I can't connect my op3 to the same smart tv, It though detects the tv while wifi is on. When I tap to connect... it's just keeps on showing connecting.

I repeat, it is not "lacking" this feature. It is available in every OP3 on OOS definitely. It may not be working for some but that doesn't mean that OP3 is "lacking" this feature.

I ahem similar problem. My OP3 is running stock nougat
I cannot use any screen mirroring app other than stock cast app.
Also cannot use screen recording apps. When I start recording, the device locks.

Sony Bravia and OOS 4.0.2 Stock Nougat
Was able to screen before the OOS update.
Any solution found?

Was facing the same issue.
The temp solution i've found is that just Clear all the wifi direct devices in your smart tv WiFi direct settings.
The try connecting it, it will connect for sure.
Hope this resolves the issue.

No problems here
