Samsung S21 Usb Debugging

[Berenguer Miramontes]

Sincethis is a new device I would suggest you contact Samsung support about this or you do a factory reset (be sure to back everything up to google account first) and see if that restores the USB debugging.

Once they are on go back to settings and you will see a new setting Developer Options and in that you turn on and off ADB debugging. As well as several other options that you probably just want to keep as default settings unless you are using Android Studio.

Hello, I am doing the same thing. I followed along and got the developer settings and everything set. Now I am wondering if I need to use Galaxy Watch Studio or Watch Face Studio and how to connect my watch in order to test the face designs.

our watch and computer need to be connected to the same WiFi network. Unplug or turn off the Ethernet adaptor if you have your computer connected by Ethernet

You cannot have Firewalls or VPN enabled.

Go to Settings

scroll down to About Watch tap on it

Scroll down to Software Info tap on it

Scroll down to Software Version tap on it 7 times and a dialog will open saying developer options enabled

Go to Settings

Allow the permissions as the watch requests them.

scroll down to Developer Options tap on it

Select ADB debugging tap on it

in those options, enable ADB debugging, and select debug over WiFi

it may take time to connect it took me about a minute before it shows the connection.

The first line will have your IP address followed by :5555 the :5555 is the port for debugging

Situation:

Trying to test android apps on a Galaxy S (Details below) but Mac is not detecting the device. Tried all the things below and have wondered whether this might be a driver issue (which I've heard things about for Samsung USB debugging).

Questions:

1) Are samsung drivers required for android USB debugging?

2) And are they available for Mac OSX?3) Any other reasons OSX might not detect device for usb debugging?

Of course, make sure USB debugging is turned on, and yada yada yada, but I did all that and still NOTHING. The moment I plugged in the USB cable that came with my S7 I got the RSA fingerprint message, and confirmed USB debugging, and the device showed up in Android Studio when I clicked Run.

I spent a night fighting this problem with my Doogee DG350, which runs the Chinese MTK chipset which has issues with USB on OS X. I found the solution was to run ADB in TCP/IP mode and then connect wirelessly:

None of these things worked for me. I'm running 4.4.2 on an LG VS450PP, trying to connect to a Mac laptop running OS X 10.10.5. Neither MTP nor PTP worked at all, even after following all the suggestions listed here and elsewhere on SO. I only got the RSA message when I chose the Internet option from the USB settings (and then I chose Ethernet).

The connection via tcpip has a potential to work. However, the port 5555 is probably not available. I know this can work because I have an app on my Android called "Synctunes Wireless" which syncs' my itunes on my desktop wirelessly via tcpip and using port 4444. So I used the ip address and this port showing on this app and I can see this device in my Eclipse. Only thing is that the device type is unknown so the "OK" button is still disabled. So this has potential to work. Just have to find the right port number or maybe something else that is missing.

So i did some research because the same thing happened to me.If the simple solution doesn't work you should check if you installed knox when you first launch your phone.If you did install knox the only way for you to activate usb debugging would be to reset your phone back to factory config in order to deactivate knox (aka not installing it again), apparently you don't have the option to unistall knox on recent phones.

I am not sure if you ever solved this problem, but I ran into this problem, and tried out many many different procedures, each of which might have helped others, but this is 2016 and a summary might help.

When I have Android Studio open, the AVD manager didn't show the new phone, but showed the old one. The old phone, when connected on the USB plug, threw a dialog asking me to confirm the fingerprint of the RSA key, but the new phone didn't show the same dialog when connected.

I still don't see the phone (but that does not bother me as I am able to see the phone from the AVD menu). adb command line utility only showed an emulator that was running, but not the phone connected in debugging mode, one that was seen on the AVD menu, up until the command was run.

A cable might work wonderfully for charging your phone from your laptop, but not work for data transfer (because different pins are used for these purposes). An easy way to check that you have the right cable, set your phone's "Default USB Configuration" in Developer Settings to "Transferring files".

Over the last few months' annoyance, I never tried this. Why the hell would that be right?! Today by chance I tried it. I got the "Allow USB debugging?" prompt rather than the "Allow access to phone data?" that we get when connecting with the other USB configurations.

This is reproducible, i.e. when you keep computer and phone connected, and flick between the settings of "Default USB configuration", the phone appears and disappears from Chrome Dev Tools Remote Devices, within a second or two. Only appears when phone is set to "MIDI".

I have found a few times that it stops working inexplicably, but it can be fixed by going to Developer Options, setting to something other than MIDI, waiting for the "pling plong" sound from your Windows computer, and then set it back to MIDI.

I've had the same issue and it turned out that having the USB mode set to file transfer instead of charging caused my issue. As soon as I set it to charging mode, it fixed my problem and I was prompted for debugging.

After doing all this, my root finally worked! I'm not sure if the adb steps are necessary, but I went ahead and performed them. Then when I reconnected my phone, the dialog for giving my computer permissions actually popped up and I was able to root.

It seems like the profile of the computer(perhaps the RSA key fingerprint) was automatically recognized by the android device and so it didn't ask for any permissions. From there, I'm still kind of trying to understand it. But basically, as soon as I reset(factory reset) my computer, it started prompting me for authorization again. I'm sure the factory reset was on the extreme end of options, but it worked in the end.

Our backward compatibility policy only supports a gap of 2 versions. This means that Firefox for Android (aka Fennec) can only be debugged from: Firefox 68, Firefox 69 and Firefox 70. Since Firefox release channel is now Firefox 72, the only compatible release officially available is ESR68.

In order to enable the new about:debugging on Firefox 68ESR, you need to go to about:config and set devtools.aboutdebugging.new-enabled to true.

Or you could use WebIDE, which should still be bundled in Firefox 68.

Hi. As the title says, I cannot debug any Delphi FMX application on my Android phone. I'm using the latest Delphi version (Alexandria, Update 1), and my phone is Samsung A52s. When I try to run in debug mode, the app installs, a black screen shows up on the phone, and RAD studio layout transforms to Debug layout. Two outcomes may happen after that:

My A51 (and all the the other Android phones I tried) still work OK.

I've tried on both RAD Studio 11 and 11.1.

11.1 did some odd things, I disabled USB debugging, reconnected and it asked about trusting the computer. Then it decided it wasn't in developer mode any more so I had to re-enable it.

Wondering if the Samsung updates broke something?

For those who had the same issue, it seems that the 11.3 update fixed it. Sometimes though, I have to first install the app on the phone, then go to Developer options and select that app in the Wait for debugger to connect option.

While the Android emulator is a great way to rapidly develop and test your app, you'll want to test your apps on a real Android device. To run on a device, you'll need to enable developer mode on the device and connect it to your computer. For more information, see Run apps on a hardware device on developer.android.com.

Depending on the UI your device is running, the USB debugging option may be in a different location. Consult your device documentation if you can't find USB debugging.

You'll receive a prompt to trust the computer on your device if you haven't used it for debugging before. You can also check Always allow from this computer to prevent requiring this prompt each time you connect the device.

If your computer isn't recognizing the device when it's plugged in, try installing a driver for the device. Consult your device manufacturer's support documentation. You can also try installing the Google USB Driver through the Android SDK Manager:

It's possible to debug an android device over WiFi, without keeping the device physically connected to the computer. This technique requires more effort, but could be useful when the device is too far from the computer to remain constantly plugged-in via a cable.

By default, the Android Debug Bridge (adb) is configured to communicate with an Android device via USB. It's possible to reconfigure it to use TCP/IP instead of USB. To do this, both the device and the computer must be on the same WiFi network.

The Google USB driver is required to perform adb debugging on Windows with Google devices. For more information, see Get the Google USB Driver on developer.android.com. Windows drivers for all other devices are provided by the respective hardware manufacturer. For more information, see Install OEM USB drivers on developer.android.com.
