Showing device on screen. - Nexus 4 Q&A, Help & Troubleshooting

Hello!
I have a broken Nexus 4 and I want to show its screen on my computer and interact with it.
It is possible?
If so, how?

You can use AirDroid mirroring for that, but you'd have to find a way to install and configure the app on the phone. I did it on my broken OnePlus One by using a mouse connected to the phone via bluetooth. Your phone also needs to be rooted for mirroring to work.

Because tv has hdmi input and laptop has hdmi output. You are trying to output hdmi from your phone which should go into the input. Since your laptop is not an input you cannot and will not see anything.

Is there any adapters that are made to lets say Hdmi to usb? I've seen one for hdmi to svideo. But most laptops don't have that either.

Are you just trying to use the laptop screen as a TV for the phone?
Yeah. Pointless I know I mean its a laptop. But my computer has hdmi inputs. Well the monitor does.

If your monitor has hdmi input then just plug in the hdmi cable into it.

so what you are saying is it shows nothing either on my phone or my laptop after connecting the HDMI cable ?
actually what I need to do is to run webtop on my computer.so i need to root the phone.before rooting i need to know all the things are working perfectly .
After rooting would it show those options in my phone and the laptop ?

@zeealot, you cant connect your phone to any laptop via hdmi... the hdmi port on your phone is for output so as the hdmi port on most laptops so therefore you cant connect output-to-output
if you want to display/output your phone on a bigger screen, you can only connect to a tv or an external monitor that has hdmi input port... also, rooting your phone doesnt have anything to do with it... I hope I explained that clearly to you

You could try using a HDMI capture device like this one:
http://www.blackmagic-design.com/products/intensity/
but it is probably expensive.
$200 its professional grade used for way more then what your wanting it for. You can actually hook up your xbox or ps3 to your laptop with this and record the game play as your playing it.

Why don't you just buy the laptop and be done with it? You obviously have no clue about how HDMI works, and I wouldn't trust you trying to perform mods to your phone because I know you'll end up here whinging you bricked your phone.
Sigh.

you CAN NOT connect it to a laptop BUT if you're referring to an external display with hdmi input (monitor/tv) you can still use webtop without a dock... just search the forum for hdmi mirroring
Is there any way to make the HDMI output of the laptop to HDMI input ?like by using a converter ?
No. It's not possible. Period.
Use your TV, or get the lap dock, there is physically no way to make your laptop show the webtop off of your phone without an extra tuner card (hdmi are expensive, and not worth it).
Btw, google is your friend.

I think yhe2x had made it very clear already! Buy a new LapTop with HDMI "IN" port.
Even though I think dingdong a laptop with any form of input would be nearly impossible. Laptops just aren't something people expect, or use, as a secondary display.
Plain and simple... There is no way to connect your phone to the laptop and use webtop mode. TV, yes. HDMI computer monitor, yes. Laptop, no.

[Q] How can I control my N4 with a broken digitizer?

Is there a best/easy solution to control an N4 without the use of the screen? My digitizer is cracked and I want to either control it using a mouse, pc, mac, other android phone. I know there are apps out there that will do this, but the setup is a bit difficult since right now I don't know how I can really control the phone without the screen. The end goal would be to hook up the n4 to a tv or speakers and use it as a dedicated streaming device.
Also, I'm rooted and willing to dive into adb if that's the answer. Thanks for the help.

Why don't you get RMA? I think it maybe impossible unless you sideload an app.

Sorry, but have to ask - does your TV support it? What is the model#?
If it does, you should be able to enable it then just turn on screen mirroring on your phone.
My Samsung TV doesn't have the option for screen mirroring built in, but I accomplish it with what I do have - the MHL HDMI dongle and the allshare cast. One is a direct connection, the other is wireless.
I'd imagine it works the same as the allshare cast hub. When it's on,all I need to do is turn on screen mirroring from the notification window and it automatically connects to it. If you share the model of your TV myself or someone can look it up. Or you can check out your manual first then go from there. Without knowing what you have, here's an example :
http://www.samsung.com/us/support/howtoguide/N0000058/6528/41579/UN55ES6500FXZA
AFAIK it has to be a newer model for the mirroring without the dongles. : http://developer.samsung.com/forum/thread/is-it-possible-to-test-screencast-using-eclipse-simulator/141/219986#post1
Hope that helps.
Can a rooted phone screen mirror? I just got a new 60in samsung but I cant get mirroring to work. It connects and then drops a few seconds after.

I had to update the ROM in my smartv before I could connect my phone to the TV and then toto the phone. Some samsung devices can mirror the TV as well as have the TV.

LN32D403E4DXZA specifications don't indicate built-in support for miracast. So you would need to get either the Allshare cast, or another miracast adapter like the netgear push2tv (PTV3000 or PTV2000) to be able to mirror your phone to the TV.

Certainly.
Personally, I find that short cable inconvenient, but that's just me. If the goal is to play movies on the phone and mirror to TV, sure. But I end up wanting to share pictures or short videos taken on my phone, on the big screen. For that, I would prefer the ability to have the phone with me (on the couch) and not have to stand next to the TV with that short cable connecting it to my phone.
For now, I'm using the Roku (juice channel) to share local video/pictures, but is not the best option because it doesn't let me share my pictures/videos from dropbox or other online storage sites. I have to download it to my phone first.
Waiting for the wireless mirroring options to drop further in cost

For sure! I prefer not to have it directly connected -but was more for the sake of informing the OP.
I use the mhl dongle it like you mentioned, if we're watching something that doesn't require me to babysit the phone lol.
I got lucky when Samsung was having a 50% off promo and I picked up the allshare hub then. None of my TV's are "smart" TV's, so it works well for my "dumb" TV's.
Also, a while back, I picked up a pogoplug for under $20 and I use that for storage- kinda like a "mini NAS". You can hook up usb drives (flash or harddrives) to it and right now I basically have a couple of flash drives to serve the media to phone, so it's cool for mirroring or just while out and about. Pretty cheap,quick and doesn't require much effort so it was well worth it for me...it comes in handy because it's set up so I don't have to do any transcoding for videos - I just use the mxplayer app and the phone does the rest.
There is one thing I have yet to try, just for curiosity's sake - to run xbmc on my S4 while it's connected to the TV with the wired MHL dongle, then use my wife's phone or my tablet with an xbmc remote app to connect to and control the videos to play from the s4 while mirrored...
That's cool with the roku. Have you tried just using something like couchyplay http://www.roku.com/channels/#!details/19661/couchy-play
or rodropbox http://www.roku.com/channels/#!details/18042/rodropbox so you don't have to d/l to your phone from dropbox?
You could even use something like the cloudpipes app https://play.google.com/store/apps/details?id=com.maximussoft.cloudpipes&hl=en to automate moving/copying files back and forth on dropbox while you're not using your phone (at work or sleeping ..or whatever)

[Q] Broken screen (another one, yeah)

I have also broken the screen on my Nexus 4. As so many others have done before me. But since the phone is a very good phone, I want to use it as far as possible without changing screens. LCD screen works and shows everything that going on the phone. But you can't touch it.
In a weak moment so I reset the phone to factory settings. It was stupid, because I had turned on USB debugging. When I start the phone normally, it going to the default settings for language, etc. Since I can not use the touch screen anymore it ends here.
So I hope some of you geniuses (most of you XDA-guys are geniuses) can help or at least give me some answers:
1. What would you do?
2. Can I somehow enable USB-debugging mode from e.g. fastboot?
3. Is it possible to "fake" the settings so it's conected to my Google account? (then I can install apps from Play).
I'm not sure on the n4, but on the n5 you can hook up a keyboard and mouse thru the usb otg using wireless. You might explore that possibility.

According to Google the Nexus 4 does not support USB mouse I could link to the document at Google, but the XDA forum prevents me to link in posts since I haven't got more than 10 posts.

Anyone?
you can install a custom kernel (if you have a custom recovery, or dont have a lockscreen security) that supports otg, then use it (however the n4 needs external power, so you will need a otg -y cable or use some usb hub which gives the power to the peripherals)

Screen cracked, need to retrieve data/use phone. How?

Is there any software that would allow me to access the phone in a teamviewer-like interface? Allowing me to use all the features of the phone on my computer?
If you had adb installed and running before there are a couple of things that will allow that. If not use a USB mouse and an otg dongle. I sued the mouse method on my wife's phone when she cracked the screen and killed the digitizer. It allowed me to link it to another device via Bluetooth and shove all my info to it. You could also move info to google drive or Dropbox using the mouse. It's pretty cool, you plug in the mouse and then you have a pointer on your phone screen.

I'll go pick up an OTG dongle tomorrow and try that out. Can I install ADB on the phone through my computer?
The problem with that is you need to have the computer hooked up to the phone in order for you to verify security stuff with the adb interface. You can't have both the mouse and the computer hooked up at the same time. You might be able to use the otg dongle and use it to setup a Bluetooth pointing device (mouse, etc.) then USB the computer. Not sure, I just needed pics and other stuff off my wife's phone and otg and a Bluetooth link was easiest.
