I'm trying to connect an external touchscreen display to my S8. I'm hoping I'll use a display similar to the ones in RPi kits, such as this, but I don't know how if the phone will be able to accept the input, and if it can, if it will act like a mouse pointer, or actual touch.
Does anyone have any information they could offer?

I have a Nexus 7 tablet and a few days ago I noticed the screen glass seemed to be popping up out of the plastic a little, I tried to push it back down and the glass panel on the screen cracked along the edge.
The tablet still works fine but will not accept input from the touchscreen, I plan to replace the screen since I know they're glued to the glass panel, but until I can locate a replacement screen panel I'd like to use my tablet with an apple magic mouse.
I know it's possible to pair a magic mouse with the tablet, my question is how can I do this without being able to use the touchscreen?
Also if anyone has a source that sells the replacement screen+glass it would be much appreciated, I can't seem to find any that have it in stock.
My tablet is unlocked and rooted, running a custom kernel and stock JB.
Well I managed to add my bluetooth device, posting here in case someone else needs the information.
I used a USB OTG cable to plug in a wireless receiver for a logitech mouse/KB combo and it was immediately recognized by the tablet, so I used that to configure the bluetooth.
It can also be done by modifying the bluetooth configuration directly using ADB, but only if USB debugging is enabled. (Flashing a pre-modified bluetooth config might also work, but I haven't tried)
Hello, I have a Galaxy S4 i337 running 4.4.4 Kitkat. It is stock rooted. I have broken the screen and digitizer, so I cannot see what is on the screen and there is no touch input. The phone has a pattern lock with a backup pin. I know the pattern and possibly the backup pin, but I can't input them due to no touch input and I can't see the display. I have an MHL connector that shows the display on my TV, but I can't provide any input. I also have a USB OTG cable and a mouse and keyboard, but input with these devices is essentially useless since I can't see what's on the screen at the same time.
I was going to try the "Android Control" Windows app that I found here at XDA, however, I am unable to unlock the phone and then allow the PC to connect to the phone using ADB. I am referring to the "Allow USB debugging?" prompt. I believe USB debugging is enabled. Wifi is turned off, and bluetooth is turned off. I was thinking that I may be able to connect a bluetooth mouse and use the MHL adapter at the same time, but I can't enable bluetooth. I do not have a Samsung account, so I can't use the find my phone or whatever it's called to unlock it. Does anyone have ANY ideas of what I can try to gain access to the device? :fingers-crossed:
I'm sorry to hear that. I did the same thing trying to replace the glass on my phone. I'm sorry to tell you but you're going to have to go on to Amazon and order one the cheapest I found was for $77. I don't think there is any external application to unlock the pin pattern on your phone without being able to use the touch screen

There has to be some kind of back door or something. Surely Google isn't so inept that they have locked down MY device to the point that I have lost ALL of my data due to the lcd and digitizer being broken. Samsung Kies says that it isn't compatible and says to use something called Smart Switch, which won't work with the phone locked. I can presumably install software via the Google Play website, but that's the only thing that I am aware that I can do without operating the phone directly. I read about an app that can supposedly unlock your device if you install it from Google Play. I have no idea if it works, and that would only solve half of my problem. I still need to disable or bypass secure adb. If not for secure adb, I'd likely have full access to my device. Thanks Google; secure adb is awesome!
Ideally there would be an app that could be installed via Google Play that would automatically enable an FTP server on the device without any configuration. It would be preconfigured with the options in the documentation and would enable on install or after reboot. I have Filezilla and have used FTP before with the device via ES File Explorer, but I can't enable it with a broken lcd and digitizer.
There is a product called Samsung Remote Client/Server that I believe is intended for carrier unlocking devices. It is a paid product, but a free function of the software is the ability to bypass pattern lock. I can't get it to work though. It says:
"Opening Modemport at COM3"
"Bypassing Pattern lock...Please Wait..."
"Bypass Failed"
"Make sure you have set the correct modem or uart port as modemport!"
I have no idea what it is talking about regarding the port.
I read something about possibly being able to manually add my PC's RSA fingerprint to the device to allow adb to connect, but I can't access the filesystem to do this. As much as I despise Apple, I'm wondering if my data would be forever lost if I was using an iPhone and my screen broke. I'm betting either iTunes or one of the Apple stores could recover my data. I guess with Android, you're hosed if your device malfunctions.
Try sending an email to Josh at Mobile Tech Videos or give him a call. He has a shop in texas, and is the most knowledgable person on Galaxy phones of anyone I know outside of Samsung. You might be lucky enough to talk to him in person. (He's very busy.) He can probably get your data for you, for a reasonable price, and will also probably be forthcoming with any way you can do it yourself, if you ask. He is somewhat active here on XDA-Developers as @connexion2005.
Edit: I hadn't looked at his web site for some time. That note about not taking new orders has been up there for the better part of a year now. Also, it looks like he is making good money fixing blacklisted phones with his jtag equipment. So, I'm not sure if this is good advice or not. But it can't hurt anything to ask.
Thanks for the information. I'll look into it. I may have found a broken Galaxy S4 with a working screen and digitizer. If that pans out, I think I can connect the screen and digitizer from that phone to my phone and at least unlock the pattern and authorize my PC. I also found a dock on Amazon for $16 that supposedly lets you connect an HDMI cable and mouse and keyboard simultaneously. I'll try that if the other phone doesn't come through.
OTG cable
Use a generic OTG cable, then connect a wireless Keyboard/Mouse combo. I use one of these: Logitech K400 for my customers, works for most phones.

I appreciate the input and suggestions, but as stated in the OP:

I have a semi-complex lock pattern. Using a mouse to input the pattern without being able to see the screen is virtually impossible. I have tried. Just getting it to accept the WRONG pattern 5x while hitting at least 4 points each time is very frustrating and nearly impossible. Unless the trackpad on the keyboard you linked works differently (touching the center of the pad centers the on-screen cursor), that method won't work. I doubt it works that way in my experience with laptop trackpads. The only solution that I know of regarding OTG would be to buy a dock that enables both HDMI and mouse input simultaneously.
Regardless, someone came through with a broken Galaxy S4 that I can possibly take the screen off of to at least unlock my phone, remove the pattern lock, and authorize my PC's connection via ADB. I'm about to tear into that now.
Hello,
I have a PCB that is communicating with an android handheld via a USB UART connection.
The PCB handles a d-pad over a serial connection, also has a few other un-mapped keys.
What is the best way of having the android OS recognize the d-pad controls natively, as in I would like to map a home button, back, menu etc as well as the d-pad
It seems as though there are already provisions made within the android OS to handle full external keyboards and joysticks etc
If someone has achieved something similar, such as connecting a serial joystick/dpad/keyboard over USB bridge, please chime in.
Thank you for everyones help in advance.
BUMP!!
willing to pay for someone to help figure this out!

I've a galaxy tab 2 7.0 which is beyond repair and hard bricked, I was wondering if I could use it's display and touch as a secondary monitor for windows, with a reasonable response time, for productivity. It would be a tremendous help.

Please read the post before reply. Device is hard bricked. Software solution not applicable. Hardware solution required.
You probably already gave up on this, but I am answering this so other people get at least sortof an answer.
For the display alone you could try to use a display driver board (Just google for "make your own monitor, DIY LCD controller board" Sadly can't post links yet..)
Will be hard as soldering to the connectors of the display is annoying/nearly impossible.
Next would be touch, and there you would also need to find a driver board (designing this yourself is way out of the scope usually) and then calibrate the coordinates. (Probably okay under linux/unix, next to impossible under windows)
Overall cost would probably surpass what you would pay for a cheap, new device which could run a software solution. (which would be more portable and cleaner looking.)
If you are a linux user, you can tether the tablet to your pc, get a vnc server running on it and then stream the feed via ADB over the usb-cable to your tablet. (ADB can connect ports from your tablet to your labtop and vice versa). This means that you dont have to pay anything for an app, and also do custom stuff like just sharing certain parts of the screen to the tablet etc...
Hi,
I have a Z3 Compact with a broken screen. It displays everything all right, but the touch is pretty much dead. Shame, I loved that phone.
Thus I am looking for interesting ways to make it useful again. It runs Android 6.0.1 right now.
I have an OTG connector, so I am still able to use the device with an USB mouse - BT controller is an option as well. My most basic options are:
- emulation-handheld for old consoles like PSX and SNES
- PC Camera (with apps like DroidCam, IP Webcam)
But before that my most basic question would be:
Will I be able to use the mouse after reseting the device to factory settings? Seems like the easiest way to clear all the data.
Also, I know there are unofficial Android ROMs available - is it possible to install and use them without the touchscreen, only with USB mouse?
And now to some wishful thinking...
Are there any Linux roms for Z3C akin to Raspbian for Raspberry Pie? Z3C most likely has enough power to act as a simple desktop PC for internet and youtube, it also has peripherals (was it called MHL?) to connect it to a monitor via HDMI that should be dirt cheap by now (the question is, is it still possible to connect K&M at the same time? Is USB-hub enough?), so... maybe?
Any other ideas are welcome!

Make sure you have one of the magnetic charging cables so you can at least keep the mouse plugged in at all times AND keep the battery charged Keyboard & mouse possible IF you use something like the OLDER Logitech models with the proprietary dongle. The newer "unified" stuff won't work. BT keyboard / mouse too sluggish in my experience. If you are feeling courageous, and especially if you don't need it as a daily driver, a replacement screen is something like 25 dollars USD on eBay - get the one with a frame unless you are experienced in replacing screens - the replacement screen only units are somewhat FRAGILE.

Thanks, Nezlek! [I pozdrawiam współ-Warszawiaka! ]
Fortunately I have the magnetic cable, so no worries there. I wasn't planning on replacing the screen, definitely not that courageous. I loved that phone, but I am just not good with tinkering inside of small electronic devices. That is why I was thinking about ways of using it with other input tools like OTG mouse or BT controler. Right now I am thinking about getting a MHL cable for HDMI output and giving it with a BT gamepad to my friends kids with some games loaded. I have no other ideas, sadly.
Do you happen to know if OTG works right away after full-reseting the devicse? This is my main concern now.
Good Question ......

I assume that OTG would work right after a re-set. Why not? The support is built into the ROM. As for the MHL cable, another good idea, but you could just as easily screen cast, no? But, for 5 U$D, or 18 zł PLN (take your pick) an MHL cable is a "worth it" experiment. And, if you're feeling adventurous

From personal experience, the only real issues with the Z3C are that the LCD panel is held in place by adhesive, so you have to position those templates rather precisely, OR use glue :crying: OR double-sided tape AND, you have to be CAREFUL re-positioning the speaker. Caution and patience is all you need.
