Is there a way to change the Android display programmatically from a PC via a USB cable? I have an old phone, Samsung Moment, that I would like to convert into a simple display device. Ideally I would be able to send it properly sized and formatted image files and have the phone simply display the image fullscreen. I am able to use ADB to send and receive files to the phone, but the phone is not yet rooted. If rooting is required, then I guess I'll do that first. Is there an app for this already or is it something that can be done simply by issuing ADB shell commands, sending files into the right places? Also, I would of course need to turn off the automatic screen lock. The phone should not need to respond to any input; it would just be a display device. Is all of that doable via some app or is this something requiring specialized ROM's? If so, what are my options?
Thanks!

As many of you may know, there's currently no native way to screenshot an Android Wear device, and at this point it's pretty cumbersome to need to get to a computer to run ADB just to get a screenshot.
I've managed to at least remove the need for a computer, as long as your phone (or whatever your watch is paired with) is rooted (your watch does NOT need to be rooted), through a simple script I threw together, wearcap. It properly loop-back connects to your device and then connects to the watch over ADB. I'm sure this can be made into an actual app, but I don't care enough or have the time to do it. All you need to do is run it as root with whatever terminal app you desire. Wearcap assumes you've done all the necessary USB debugging settings, which can be found below. Screenshots are saved in /sdcard/Pictures/Screenshots/ on your device and then removed from the watch.
Everything else is pretty self-explanatory, just push the script onto your device, give it executable permissions and be on your way. As noted in the script itself, make sure your screen is on during the connection process, my Moto 360 would typically fail to connect if it was off.

Sorry about that, it's been attached as a text file now.
an apk will be wonderful
I can wrap it into app tomorrow if CEnnis91 is OK with it, I'm thinking to add change of the density as well through adb.
Hi all.
So, I have this Nexus 5 with what I thought was a broken screen. It isn't; it's actually damage to the motherboard video output. This was given to me by a friend to salvage somehow and I don't want to disappoint him. I want to either clone the phone (backup and restore) or download the saved stuff in some form.
Only the screen is affected. The phone takes calls with no problem and it works all right otherwise. It even hooks up to the computer and I can see all sorts of files... including *cough* femdom porn *cough*. The problem is that the phone is not rooted and USB debugging isn't enabled, so there's no way to get into the ADB shell so that I can do my thing.
Is there a way to backup and restore from, let's say, fastboot? Contacts, user names, etc? If not, is there a way to enable USB debugging without access to screen?
I have a Samsung A51 with a screen that is damaged to the point I am unable to see anything. I can hear incoming calls, so I am assuming the phone is in working order besides this. I would like to gain access to the phone, either with a mirrored display via HDMI, or Slide Sync. I am unable to unlock my phone. I have a pattern unlock. I do have a USB C to HDMI adapter, but I am unable to accept the notification. Using ADB or another tool, am I able to gain access to the phone? I would like to pull some information off of it prior to getting it repaired / replaced. Thank you.

Thank you for the reply. The problem with using an HDMI out, is there is a notification I have to accept for it to work. I am unable to accept the notification.
If ADB got successfully enabled then you can pull userdata by means of ADB.
Hello, I just broke the screen of my OnePlus8t Verizon network unlocked phone. The computer I previously linked 8t with also has a broken screen. ... Rains it ..... My Phoe has some important information in docs and screenshots I need to get. I just turned off ADB debugging thinking "Oh I don't need that just yet" the very morning I broke the LCD. Good news, I can still answer it. I already have adb.exe except in ADB shell it shows as unauthorized. I need those files like yesterday. I have an otg/ADB flash drive, but I still can not connect to retrieve files. I can see my phone when I directly connect to comp without the flash drive, however, I can not access it. I have tried to put the phone into recovery, but I have no way to enter the pin as I have tried to guess where it is. How can I receive the data I need from my phone?
Thank You.
P.S. I have little knowledge and only learn what I need to know for whatever project, in other words, I can not code and I barely speak dos.
Is the touch screen still working then?
If it's showing "unauthorized" you can try to plug it into your desktop and then hit the "authorize" button on the popup that you can't see.
Here is where ok is on a different phone. It's somewhere near there on yours.

I have tried that. The finger print unlock screen only works ⅔ of the time. I have no way of knowing if it's unlocked. I keep my touch sounds silent. I keep trying to find where it might be. I have tried to slide as if answering a call. Is there a way to force the USB settings for media transfer? Maybe through Google? If any platform knows it's my phone is Google. I can go to the play store and push apps onto it. Unfortunately the two adb drivers I have installed on my Android didnt work.
Oh, actually, you've got it easier! The OnePlus 8t supports HDMI over USB Type C.
https://forum.xda-developers.com/t/does-one-plus-8t-have-video-out-through-usb-c.4465629/
Buy an adapter and hook up an HDMI monitor/TV.
Or just use a new monitor on the computer that is already authorized.
Is there any other way. Right now it is not with in the budget to afford any extras even with the price tag of $20. I am hoping there is a way within an adb shell to force turn on the adb debugging. I have developer options enabled. I would just rewrite the documents, except some of those items I need include the text messaging history. If I can't force the adb, can I remotely back up the phone? Is there a trustworthy app for that? I do have quick settings installed and if my memory is correct, I believe I have sideline installed even.
Hi guys,
I cracked my 3a's screen so I've just upgraded, but unfortunately a couple of key apps I use (namely language apps which I have tons of progress on and can't migrate over with their systems) aren't transferring the data over. I've tried adb transfer, I've tried looking in the data folders, no dice. I can see my phone's screen when it's plugged into my PC, but the prospect of trying to root it is scary as if I can't see the screen at any point, I'd basically be stuck, and unlocking the bootloader could potentially delete the data on there anyway depending on the method used (haven't looked into this too much just yet).
Any ideas how to get this data off of the 3a? Thanks in advance!
If in this model whether a USB or BT-connected mouse works, you can perform a standard data transfer via a google account.

You can move your data to a new Android device from another kind of device, or start fresh with your new Android device. Important: Some of these steps work only on Android 10 and up.

I've already done that and ADB transfer, only the app itself "transfers" (redownloads off of play store) the app's data itself doesn't transfer.
Just to be clear; this is a non-debuggable app. ADB Backup just results in a 0 byte file. I'm 99% sure I need to root the phone to back this up, but I need to be able to do so while 1. accounting for the blank screen that'll mean I can only see what I'm doing when USB debugging works and 2. without factory resetting the phone in the first place as that'd defeat the whole point.
Any ideas?
