[Q] Help: Adding bluetooth mouse to Nexus 7 with broken touchscreen - Nexus 7 Q&A, Help & Troubleshooting

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)

Broken Screen & Digitizer, Can't Unlock Pattern or Allow ADB

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.

LG G3 - Cracked Digitizer / Touch screen - Tips & Tricks

I had a crack on my digitizer / touch screen on my LG G3 but it was not large enough to damage it entirely. I ordered a new assembly but it took forever to arrive as the model (D858HK) was not available locally in my area and had to shipped from China. Here are some useful tips if you face a similar situation and you need some time before you can get the mobile repaired:
1. With a USB OTG cable, the mouse works! Even a wireless adapter that connects to mouse and keyboard works (....I was using these with my desktop)!
2. With bluetooth pairing, you can have a keyboard and mouse from an app installed on another mobile (I used Blackberry).
3. LG Keyboard app has a one handed operation that shifts the keyboard to either right or left of the screen. If you activate that, then the keyboard can shift to one side of the screen where touch still works.
4. Latest versions of TWRP can also handle USB mouse and are a big relief for taking backups before sending over the mobile to a repair shop.
5. Rotation Control app can enable rotation to all angles and even for apps that do not otherwise permit rotation.
6. If you do not have a mouse handy and want to take a TWRP backup, then Flashify can come in handy. Read up on openrecovery scripting that can be handled by TWRP.
7. If you are rooted with xposed and tweaksbox installed, then you can crowd the navigation bar with additional buttons such that the 3 must have buttons are at a place where touch screen works. Even otherwise, navigation bar can take up to 5 buttons.
8. If you want to use the 4G capabilities of the mobile with other phones, you can try bluetooth or wi-fi tethering. While bluetooth tethering does not consume too much power, wifi tethering can be power hungry. A way to get around that is to use Automate app and set rules there, which help you automate the wifi hotspot and switch it off later according to requirement (fixed intervals, when another device connects on bluetooth, when a notification arrives etc etc).
9. Keep MTP enabled and learn to use ADB.
10. Use a bluetooth headset to receive calls.
11. Use T-Action to receive calls and gesture settings to turn down volume / ignore calls.
12. Activating auto correct for keyboards can also help.
...maybe some more and I will add these later as they come to mind.
But hope you never face this problem. Cheers,

Bluetooth mouse delivers much better battery life. But then, I had to use mouse for some very specific purposes as 80% of touch screen was working for me.
Yeah i left the few Bluetooth mice I had at my dad's house only to realize he lost all the usb receiver pieces... Time to get a new one as only half the left side about a half inch in and sometimes the bottom works if I'm patient...

But with a Bluetooth mouse and an android phone that has Bluetooth, why would you need a receiver? They should be able to connect directly on Bluetooth.

How to enable OTG on Nexus without any touch abilities.

Greetings All !
I have 2 old Nexus 4. The are functional except touch. I bought OTG adapters just to find out N4 didn't had that.
I have found a fiew tutorials on how to get OTG, but they all use the screen at some point to get the new software in.
I've figured out that maybe via ADB (and volume up/down/power buttons) I could be able to do this ...
Anyone did that in the past ? I also have a Bluetooth mouse but I can't pair it because I can't touch the screen.
Thanks all !

Looking for ideas to make Z3 Compact with a broken touch screen usefull again

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.

Pairing NON-media/input Bluetooth devices (OBD2 dongle)

Hey everyone! I bought an Onn. Streaming Box at Walmart a couple of days ago, intending to run Torque Pro on my car's preexisting Backup Screen w/ a Bluetooth OBD2 dongle (a tiny $25 self-contained Android box seemed to make a lot of sense for that application). I sideloaded the Torque apk onto the box and used a remote app w/ mouse cursor to set up the layout, but when I went to finally pair the OBD2 dongle, it wouldn't pick it up. Since the screen just says "Accessories", I'm guessing you can only pair things like headphones, controllers, keyboards, etc.
I also tried sideloading "Bluetooth Direct", and forcibly connecting to my phone's Bluetooth address (just to test), and it couldn't connect (it seems like that app doesn't work for a lot of people though).
Is there any way around this?
I'm waiting for a powered OTG cable to be delivered today, so I can root and hopefully figure something out that way. It seems weird if it's really a limitation built into the OS, since regular android is buried underneath there somewhere, and it isn't like the box has some special Bluetooth hardware that limits it to certain devices.
If all else fails, maybe I could just get an OBD2 to USB cord and plug into an OTG, but idk if that would work either (it should on other Android devices).
And for anyone wondering, yes, the Android TV UI optimized for giant 4k TV's does not work well on a 5" 480p HDMI -> RCA screen, LOL.
Figured this out if anybody wants to do something similar, I just sideloaded the app "Bluetooth Scanner - Bluetooth finder - pairing" (com.pzolee.bluetoothscanner), and was able to pair it right away. I am running LineageOS and rooted with Magisk, but I'd think this should work on stock too.
