Can't Find PTP in usb settings - Samsung Galaxy A8 (2018) Questions & Answers

So on my Galaxy A8 I have developer options unlocked with USB debugging on and when I plug in USB to my computer it asks me if i want to allow access to phone data. Deny obviously makes it so its only charging but accept and I can access files (all well and good so far). However when I go to Tap for other USB options it has options for Use USB for: Transferring files, USB tethering, MIDI, Transferring images, and charging phone only... however I can't actually change any of these options.... So why can't I change the options, and is Transferring images ptp?

Hi I just did tried it in USB Default Settings and it works for me
I am able to chnage any kind of USB mode
try it with the phone unpluged from the computer maybe !

Yeah I'm in usb settings but the actual settings are locked out from changing... does anyone know why this is?

A8 USB
I have this problem too. I can 't choose for other usb options. I haven't enable USB debugging.

Hi, if you enable developer options then you can choose under developer options - default USB configuration - which option you want.

i tried all of those options and none of them work, is there any other ideas?

Mass Storage On Mac

So my mac wont recognize my devices internal or external memory card. Anyone else have any problems?
edit: started working for some reason.
Edit 2: I figured it out I had to install double twist and by default it enables auto mass storage mode with USB debugging enabled. You can not achieve this otherwise.
I have the same problem, and even have double twist installed. Still no luck, but I'm still looking. There have been several occurrences where Samsung devices of multiple types not communicating with OSX.
As the OP stated, I think you have to enable USB debugging as well. Did you do that?

goto settings, application, development, then usb debugging!
On the Captivate, prepare your phone by Settings > Applications > USB Settings > Ask On Connection. Also, Settings > Applications >> Development > USB Debugging needs to be turned on.
Then connect the USB cable to the Mac, and drag the notification bar on the phone. It'll say USB connected - choose that and then it'll ask to Mount. Once you mount the SD card(s), they'll be visible on Mac OS X (Snow Leopard).
At least, that's what I did. No need for doubletwist.

Charge isn't going into USB Mass Storage

It was working before I rooted.
I am using PBJ Voodoo Overclock Kernel with 1.8.5 Gummycharged and the SD card fix, before I flashed the kernel/rom/fix the mass storage was working fine, I could drag and drop but now (even though it's set to USB Mass Storage) whenever I plug it in the only thing detected is 'CD Drive (E: )'. Can anyone help? I'd really like to start putting my Music/Videos on my Charge. Thanks in advance :]
Try either:
Enabling USB debugging mode (Settings --> Applications --> Development)
OR
Setting the USB mode to ask on connection

Debugging mode works as a temporary solution I guess, it causes alot of problems with my computer, it freezes it up and most of the time it can't finish the copy process, right now I'm just using my MicroSD USB reader, if that ever fails I could just put the SD card in my old phone which worked fine, thanks though
I am having the same issue. I got the phone yesterday and rooted last night and it won't connect either. It'll charge fine, but that's it. I am on my work PC so I cannot do much testing, but putting it in USB debugging mode at least made the PC recognize it.
I had to set it to ask on connection for it to work for me

I did a quick reboot and enabled the debug and it seems to work now thanks. Seems like the sd fixed works afterall. Thanks everyone.
I cannot get phone to connect in mass storage either every time it loads it brings up a scan drive screen with quick fix or continue without scanning. Then opens as CD Drive, I am completely lost and getting no feedback, have yet to try SD Fix or where to get it or how to get it.
Have you done everything I told you? After you do all that, go to setting, USB Settings then check "ask on connection."

USB Connection Options dissapeared

No idea what's changed or happened. Same phone, Same computer, Same cable. When I first rooted I was able to connect the phone and change the usb connection type no problem. Now when I plug in it just starts charging and there's no notification for me to select to adjust the type of setting. USB Debugging is still selected in developer options.
Any ideas on how to fix?
EDIT: Nevermind. I fixed... somehow. not sure what I did. But GTG now.

Can't get usb debugging working

Phone is rooted and on android 10 and xxxnolimits installed
I connected phone to pc and only charging. Tried 3 different cables, including official one and 3 different USB ports and not showing on pc. I can hear noise it's connected to pc but then another noise to disconnect
Usb debugging is enabled and default usb configuration I can change to file transfer, usb tethering , midi, ptp & no data transfer. I changed it to each of them still not showing
There is no option to choose mtb from drop down notification no notification is there
I rebooted phone and pc and cleared cache. Also i app settings allowed notifications.
I'm at the end of my tether trying to figure out what issue is as was working previously.
Now all its doing is charging
Any suggestions

Try uninstalling and reinstalling usb google drivers on your pc ( or your appropriate driver's for your phone).
Install OEM USB drivers | Android Studio | Android Developers
Discover links to the web sites for several original equipment manufacturers (OEMs), where you can download the appropriate USB driver for your device.
developer.android.com
Are you talking about usb drivers?
I installed this one

Usb OTG debugging issues Xiaomi

It goes like this. I have tried 3 type-c cables and they are all fine when I connect it to my wife's phone to my pc. And when I try these cables, connecting my phone to my pc, the menu or the default usb menu on my phone does not show up. The options where we need to select one, like, the file transfer, usb tethering, transfer photo, midi. It even won't detect any kind of external usb or OTG drive. My usb debugging mode in the developers option is also ON. I am wondering, if my phone needs to replace the charging board or an update or re-firmware can do the fix. Thus, I have done a hard reset and factory reset, but, still nothing happens.
Can anyone know what the issue could be? For the one's who had experienced this? Tia

Thanks for the reply. But, sorry my Xiaomi Mi 10T does not have that OTG on & off switch.. It would just automatically connect if a usb is inserted. My usb debugging is also on, but, it cannot detect the inserted usb drive.
