I used Vysor a couple of days ago to test an app I created. The next day, my keyboard suddenly changes into Vysor's hiding the keyboard on the screen. Good thing I was at home to recon the phone on my computer so I was able to unlock the phone and change back to my default keyboard. I'm kind of upset that I absentmindedly turn off the remote debugging thinking I won't be needing it on for the mean time. Yesterday a notification pops in saying "Vysor is hiding your keyboard". Until now I'm not able to unlock my phone! I already boot up the phone, tried otg cable and used bluetooth keyboard but there is no use. I can't use vysor or any other app as remote debugging is turned off. I still can't get in! I can't reset the phone to factory default as I have important files inside. Can someone please help me.
try using the "safe mode" for your smartphone then uninstall vysor, it works for me. After turn off your phone and then turn it on.

Currently working on an Android app that's gonna be used in a kiosk setup (on a tablet, always running, only this one app, etc etc).
We are using Lenovo tablets, with a connected USB hub for USB devices and also for powering the tablet. Generally, this works fine, but when the power is plugged in, the tablet will show a system dialog saying "check your charger connection" as the tablet thinks something is wrong with the charger (there isn't anything wrong, it charges fine, so I assume it's some kind of issue in the USB handshake).
Now, obviously I should get in contact with Lenovo about this - but in the meam time I was thinking if it might be possible to programatically dismiss this dialog in some way?
Is it possible to "catch" when the dialog opens up and dismiss it from the app in some way?
Thanks in advance.
The first day my V60 thinQ smart phone worked fine with android studio. The next day after working on my project for about a hour my smart phone no longer showed up in the run/debug configurations drop-down. I was not able to run the app on my device.
I went to trouble shoot device connection
When I clicked on Re-scan device my smart phone showed up. Also in windows Explore my smart phone shows up,
Right before my device stop showing up a dialog came up asking me what i wanted to do after plugging in my smart phone. I forgot exactly what it said and what I clicked on.
Does any one know what is going on?????
I believe, the popup that you saw right after plugging your device is asking if you trust your PC to connect over adb usb-debugging mode.
Sometimes, this happens to me. The way it works for me is: going to Developer Options > USB Debugging Mode. Then, i disable usb debugging then, re-enable it again and after that usually Android Studio detects it or, it shows the popup again. If you don't see the popup just unplug and re-plug your device once.
The popup should look sth like this with an RSA fingerprint of your computer:
Now, you have to click: "Allow". And, android studio should detect your device.
I really hope somebody can help me with this.
I have xperia z5 premium, power button stopped working a month ago or something, but the phone was working perfectly fine. Of course, I made a mistake and did not charge it in time and it turned off. Now I can't get it to turn back on because the button is not working.
I explored all my options and I realized I can do fastboot reboot through fastboot and adb. However, I can't seem to get my phone to go into fastboot mode.
I hold volume up button (which I know for a fact is working), I plugin usb, and instead of getting that blue led light everybody keeps talking about, I just get a red led and then a green one after the sony logo that signals the phone is charging.
I installed ADB and xperia z5 premium drivers and I still can't get it to work. When I type fastboot reboot it says when I try adb reboot or adb reboot bootloader it says "error: device not found".
I've also installed xperia companion app and when I plugin my phone it shows a screen where it says: "Your device is locked
Unlock require
Unlock the device using password or fingerpint if needed
Allow data access
On your device, select the option to allow data access"
I've tried doing the same thing with adb on two different pcs, always get the same result. Phone just gets to charging screen and keeps charging instead of going into any mode.
I also tried holding volume down button and plugging in usb which is supposed to be recovery mode or something, but that doesnt work either, I also get charging screen. And I'm 100% sure both my volume up and volume down buttons are working.
What am I doing wrong?
P.S - Debugging mode is not on, im 100% sure since i never turned it on.
Somebody please help!
Thanks!
try downloading the sony xperia flashtool and boot your device in fastboot mode by holding down the volume down button and inserting the usb cable a blue light should appear, open up the flash tool and wait for the device to be detected if not detected, goto c drive then inside the flashtool folder there should be a folder named drivers, open it up then install the drivers for your device. back to the flashtool... when your device is detected, click on the lightning bolt icon and select fast boot mode, then you should see a window pop up and click reboot device into system.
hope this solves your problem
I've got the LG P970 phone running on Gingerbread with a broken screen. By broken screen i mean that screen displays nothing - it's lighten up, all black with color lines but it's touch sensitive (i believe). I've got important data on it and I want to get it back. Unfortunately USB debugging mode is disabled on the phone so adb devices command on linux shows empty dialog.
So here comes my question: is there any possibility to remotely turn on usb debugging mode on android device?
This is how I solved this problem (on a Samsung Galaxy S4):
This assumes that the phone's screen does not display anything, but the touch input still works.
Figure out how to take a screenshot on your phone without using the UI. On the Galaxy S4, you can use hardware buttons to do this.
Unlock your phone's lock screen, and connect it to a computer.
Open the phone in a file manager.
Find the location where the phone stores screenshots.
Take a screenshot on the phone. Look at the updated screenshot.
By doing this, you can perform an action on Android, take a screenshot, and see what screen comes up. After doing this awhile, you should be able to find the USB Debugging menu.
Simple, use a new phone say an S4 to your cracked broken S4 and get to the video port (several youtube videos on this) hook the new screen to the old phone and now you have access to debug set usb or transfer all the files its just as simple as plugging in a working screen!
