USB debugging mode does not work fully - Galaxy S 5 Q&A, Help & Troubleshooting

Hello,
I have Galaxy S5 from Verizon and I am having a trouble making USB debugging working.
It is a little bit interesting that I enabled USB debugging mode and typed "adb devices" on my PC terminal, I see my device listed.
However, I do not see any USB debugging icon on notification bar. Whether I turned on the mode or not, my phone shows no sign at all. This also makes another problem that I am trying to use one of the recovery softwares but even though I enabled my USB debugging, the software does not recognize my phone. I went to my Device manager and I do not have any problem for drivers. I even re-install Samsung USB driver several times, but no help.
I have another Galaxy S4 from Verizon and I have exactly same problem. adb devices work but no notification bar icon. But when I tried out with my Galaxy Nexus from Samsung, I do not have any problem.
Could someone please help me how to resolve this issue?
Thank you very much.

Hmmm.... I have no icon for it on notification bar.
However, you should be able to see item Developer options like here (screenshot 1):
Also, you might try re-enabling USB debugging on the phone. If enabled, you should get message like this (screenshot 2):

Thank you so much Bodisson.
Apparently, my Galaxy Nexus is older version (ICS) and my other phones are Kitkat. I am used to seeing that debugging icon and thought it would do the same thing on upper version. It seems like at some point, this icon is no longer in notification bar. Though icon is not there, USB debugging works!
Thank you so much for your answer.

Possible JI6 OTA bug, no USB mass storage option?

Looks like a bug to me, Suddenly I do not see the "USB connected" message on the notification bar! I have to disconnect USB and change mode from mass storage to something else and then change it back then connect USB and it shows the USB connected message with mount option.
Never had this problem with any previous builds. Also, I see the accurate battery mod shows "plug" sign while USB is connected but no "USB connected" message or mount option!
Any comments people...anyone with this problem on JI5 leak?
Simple question first. Did you leave de-bugging enabled? I updated my device thru Kies (one of the lucky ones it seems) instead of flashing Eugene's or the Odin mount and I haven't had that problem. I think I saw someone in the orginal JI5 on Kies thead mentioned this too. I tried to replicate their bug but my seems to 100% good. What's your OS?
its a bug, with mine is seems to come and go

Thanks for the reply. I flashed it through ODIN on Windows 7. Also, USB debugging was never enabled in the process. It seems like a bug because it comes and goes, randomly. Maybe this was one reason Tmobile told us not to upgrade...

Good to hear I am not alone with this problem...thanks for the reply...
hopefully we'll find a workaround...
Just wanted to note here, flashed to stock, formatted internal sd card, upgraded to leaked JI6 and the bug still exists, hopefully OTA JI6 fixes this
Tried OTA, erased everything, flashed from scratch still the same issue...hopefully someone has a solution, if not then this adds another reason for Froyo update
That's wierd. I upgraded to OTA and problem went away for me.

It's not really a bug. There is an option under Settings > Applications > USB Settings. Mine wasn't showing up either so I swithed it to "Ask on connection" then plugged the USB back in and that worked. Then I switched it back to "Mass storage" and now it immediately gets ready to mount. I guess you just have to set it that first time.
Its a bug with leaked JI6. This thread started with leaked JI6... Think he recently changed headline. And you solution was temporary fix with leaked version problem would come back. Can't comment about OTA since the problem went away with mine

Ok, Well I can let you know that it doesn't come back with OTA. You should flash JI6 The other builds are buggy.
wow, for those who went all the way to reformatting internal sd because of this im sorry.
all you have to do is go to settings> app settings> usb settings> and change to ask on connection
thats it, i would not really call it a bug
oh yea, and thats with JI6

THIS solves it. Just did that and everything is back to normal. With that out of the way, this JI6 software is close to perfect (the RFS file system thing is the imperfect part). This is the software this phone should've launched with. Now if they can just go to a proper file system in their 2.2 update, Sammy will have a beast of a phone.
Thanks for the replies guys. I have set the default USB to "mass storage" instead of "ask on connection" as I don't want to make a selection each time.
Now, when I connect the phone I see USB connected and sometimes there is a USB connected message in status bar with no mount option and sometimes there is no USB connected message at all... now sure what's going on. I've been seeing this problem since JI5.
I've also read some threads about this in QnA forum..thanks...

Just for the heck of it, if you haven't tried already. Check off debug mode. Because when you plug in usb debug mode pops up and maybe usb will also every time
Thanks for the reply... Yes I now I leave the USB debugging to always enabled. This is the only way the USB mass storage option is always presented on USB connect.
Hopefully Froyo fixes this as I've seen some other people having the issue as well...
I have never seen this issue on JI6. It always pops up "USB Connected: Select to copy files to/fom your computer" in the status when I plug in the USB cable. It's never failed, even when I had USB Debugging off.

Just FYI, I was having this problem when I flashed the JI6 update via ODIN. Mounting would only work when I had usb debug mode on. However, I disabled USB debug mode and then went to
Settings -> Application Settings -> USB Settings
I then changed it from mass storage to ask on connection and then back to mass storage and it gives me the option to mount in status bar just fine when I connect it to the computer via usb.
HTH.
I noticed that after the update i don't get updates ffrom the market place anymore?
Anyone experience the same thing?
Are you using the auto update? I'm not sure it tells you if this is on.
When I connected to my mac (debbuging has to be left on) I get a menu to either connect to kies,mass storage and one other.

MPT connection once again

I already asked this but couldn't get a proper answer. I don't get this screen anymore when I attach GT 10.1 to any USB. I am going to root my tab, and I want to know if this is normal. To better explain myself this time I am attaching a picture of my SGS2 on USB connection. This is what I am not seeing anymore on my tab.

Is USB Debugging on? This may be the cause.
Thanx but no. It is off and I can sync with KIES or see my tablet in windows explorer. I can say that I prefer this. I don't need USB debugging anymore. I can do anything with my tab, still connected to USB and dont need to press home button to return to tab. As though KIES mode is disabled and still active. I wonder if this is an abnormality. I am scared to root my tab.

C'mon guys. No one here in the same boat? Just care to answer. I just rooted my tab fine, but this issue is really occupying my mind. It seems that my tab is stuck at debugging mode. When I check debug, my tab disapears from windows explorer. Nothing, nada! When I uncheck debug, it is there again as a phone icon. Titanium backup tells me to put debug on, and after I check it, it still tells me to check it.... but does the backup fine. I am really confused here. Please... someone...explain. Otherwise my wife will put me in a white jacket with arms tied. You know what I mean.

Thats for sure, I have no PC connection when in debugging mode. Is that normal? There is no option to mount the TAB. Only an icon, bottom right, shows debugging mode and when touched it gives you the option to quit debugging mode.... and I am really surprised no one has any idea. Where are the gurus?
I'm confused, what was the question again? You answered yourself so many times, that I'll address only the last question.
Even when debugging is on you have an USB connection. You can access your Tab through ADB but MTP won't work. And since there is no USB mass storage mode you can't access /sdcard via Win Explorer while debugging is active.
Have I answered myself? How my ignorance can answer itself? If someone told me, "There is nothing wrong with your tab" I would have been relieved. Just tell me this: With which update have I lost the MPT screen? (See the attached pic.) And secondly, when in debugging mode, shouldn't I see my device in windows explorer? I used to see it, and I still see my SGS2 when debug on. Thanx for answering BTW.

[Q] MTP PTP option not displayed - Resolved

Fixed.. Leaving this for others since I couldn't find it via a search. - It's under Mass Storage > Settings (3 dots upper right) > USB Storage Connection. Some how it stopped displaying.. I think because I unchecked both by accident?
Out of the blue, I cannot access my phone via usb. I noticed an exclamation next to "Nexus 4" under other devices. No clue what happened as it's always worked. So I've removed the device to reinstall. The device is not being recognized at all with USB debugging off..
When I turn on usb debugging, it'll show up in device manager under Android Device > Android ADB interface.
I have uninstalled/reinstalled multiple times to no avail. One thing I noticed is that I do not get the option to select MTP or PTP.. I believe I have it narrowed down to this being related. Any idea how to get that option back? I found a tip via the dialer on the S3, didn't work tho..##diag# or something like that.
Any ideas? ThADVANCEks

Lost the icon for media device connection

Somehow the USB symbol no longer appears when I connect my S4 to my computer. How do I get it to reappear? Thanks
Not even in the notification area?
Try this: Go to developer options and enable usb debugging. Or, if it is already enabled, turn it off and on again. Do this while connected to the PC.

USB Debugging Turns Off

When I connect to my work laptop (Macbook Pro), my phone connects as an installer. After a few seconds, it switches to a media device connection. I have the Developer Options enabled and the USB Debugging option selected, but it keeps getting turned off as soon as the phone is connected via USB cable.
It was working properly last week, but I updated to MacOS 10.10.5 over the weekend, and now it won't see my phone in USB Debugging mode.
Due to the timing of the MaxOS update, I do not believe this is an error with my phone or Android, but I'm hoping some other Macbook users may have encountered and resolved this issue. I've been unsuccessful in tracking down anything helpful, partly because of the voluminous search results for "USB debugging." I'd appreciate any help available.
I'm running 4.4.2, rooted but otherwise stock.
Thanks!
Even though no one else replied here, I thought I'd post my resolution in the event that someone else with the same problem stumbles across this thread in the future. The short version: enter *#0808# into your dial pad and you should get the USBSettings screen where you can choose from several options how your phone handles a USB connection. I ended up landing on the "DM + Modem + ADB" mode, which allowed my laptop to talk to my phone again. No clue what caused the problem in the first place, nor why USB Debugging mode itself didn't stick, but this resolved it for me. Hope it works for others, as well...
