Root should not affect Dex. What error are you getting?

I faced complete inoperability of Wireless display. DEX & SmartView stopped working, my phone just can't connect to any Smart TV and USB-C Monitor either (latter just blinks with no signal). DEX via USB cable (with Windows PC) works well though.
I searched the internet and found that somebody faced same issue for different Samsung phone models and found suggested solution like this:
Insert into
build.prop a parameter
"wlan.wfd.hdcp = disable"
I'm a bit anxious about adjustment of this file as I may brick my device.
Please advise how can I solve the issue.
Thanks!

[SOLVED] Charging but not recognized by the PC

Hi,
I connected my note 5 to my laptop today, and surprise surprise, it is no longer recognized by the PC (though it charges). It used to be fine, I don't know what changed!
I tried different cables, different USB ports and different laptops
I tried to plug it in normal mode, safe mode, recovery mode and download mode
I tried switching USB debugging on/off
I tried the *#0808# menu, and I tried MTP+ADB and CP options
I uninstalled drivers from the PC and installed the latest from the samsung website
I tried both kies and smart switch
nothing worked! I am not doing a factory reset because I have seen many people do it for other devices and none of them solved it this way! I'm waiting for the Marshmallow update, maybe it will fix this annoying issue. Meanwhile do you have any other ideas guys?

hi,
you don't say what Laptop o/s you using on laptop.?
Windows 10, Windows 8.1 Windows 8 or Windows 7...... or Apple o/s.?
Briefly my take is on this is, most probably the laptop and not phone.?
(Yes, i might be wrong of course.)
My reason is, i have Windows 10 laptop
and sometimes / a few time, ) my
laptop does not recognize my Note5
Yes, , it charges phone (just like yours) but does not recognize phone.!
I then have to re install drivers for phone I use Smart Switch to re install drivers.
Then it works ok for a while etc..
Why don't you test phone on someone else's pc or laptop to make sure.?
Overall my Note5 is mostly recognized by laptop
Good luck

Thank you for the reply.
As I have already mentioned, I did try another laptop. Mine is windows 8.1 x64 and my brother's windows 10 x64. I tried re installing the drivers from smart switch but to no avail.
Any other ideas?

hi ,
why i still think its laptop /pc drivers related.
(But yes ,i might be completely wrong ..?)
i have laptop win 10 x64 also.
The issue is of laptop, not always recognizing a device /similar as yours ,but charging device .
Other devices, when trying to connect to laptop (,not just my Note5 ),( from time to time) eg Note 2,..3 ..4 , USB flashstick ..my Polar M400 running watch etc .Device is not recognized but charging .
So for me,
its just not Note 5 but other devices also (.from time to time) .
My "take " on this issue is that it points between drivers (pc ,laptop) //// relevant devices eg Note 5 ..etc . and not just the firmware issue of Note 5 ,??
but yes, as stated i might be wrong .
good luck
Post note ,
i have to add reinstalling drivers "sometimes " help " ,
but it happens again, later. ( not recognizing device )
So i am pointing fingers, at Windows o/s + the "company/maker " of laptop ..pc and + devices .The compatibility between all three above ,combined and yes i had similar issues ( from time to time with Win 8 ../Win 8.1 etc ).
Yet, i have also found that certain of my devices
that work nearly 100% of time on my laptop !,
which indicates to me, the compatibility of devices between device /laptop ,is very good ..??
I have a note 2 and it works every time when I plug it to either pc. My laptop is lenovo with all the latest drivers. Hopefully, marshmallow will address this issue because otherwise, this means that I can't root my device.

Wait, have you tried this yet?
Pull down notification menu while phone is plugged in and there should be a option for changing from charge mode to mtp and such. Just pull down notification and tap on the biodiversity that's lasted.

hi ,
strange ,
just for the record i also have a Lenovo Flex 2 laptop ( x64 ) Win 10 .!!!
i have rooted all my devices on Lenovo laptop ( Note 2, Note 3 , Note 4 and my Note 8.0 tablet etc )
Yet , i am at moment not interested in rooting my Note5 ( i have it already a couple of months )
I am happy keeping myself busy with Theme store ,tweaks/beta apps and lately with the interesting Lockmaster app( Play store ) for lockscreen ... etc .
If i get the root "urge " i pick up my other rooted devices and use them .or /update or/ install root only tweaks/apps etc. for my rooted devices .!!
i hope Marshmallow fixes your issues .!!
good luck

Did you try clicking where it says Cable Charhing?
Edit: Never mind that. I see what you mean. That's odd it's not there for you. It definitely sounds like a PC issue. You can try completely removing all Samsung drivers and start over. Just using the Uninstaller will not cut it though. You'll have to do a system level cleaning of all samsung drivers.

The issue is not with your device. It's because of Windows. Is there another computer that you can use to connect your device to that you have never connected to before? Also make sure that you are using either the cable that came with your device, or at least a good quality cable. I've had that issue occur in the past because I was using a cheap cable.

I did plug it in my brother's laptop but no dice. I tried the OEM cable and an Asus cable on USB 2 and 3 ports, it did not work on either pc. How can I completely uninstall samsung drivers?
For users having the same issue, I found a solution (which also fixes all charging issues by the way).
If you look at the charging port, you will see a "tongue" where the pins connect. We all know that fast charging requires 5 pins not 4. The OEM cable comes with 5 as you all know. However, I found the OEM cable to be very fragile and not reliable, one pin tends to get bent without much pressure. This leads to the "tongue" going down somehow. The fix is to get the "tongue" up a bit, use a toothpick or something that does not conduct power. As for the cable, I suggest you use an Asus cable (I have 3 of those, 2 from my nexus 7s and 1 from my Zenwatch). Asus cables come with 5 pins and they are sturdier than Samsung's and they are a bit longer as well. Now the phone charges properly, fast charging and all and the computer recognizes it once again.
Hope this helps you too

I'm having this same problem these same problems. Other then I'm not able to get it to recognize even after doing everything that was said to do in this thread.
I feel like I'm missing a file? I was messing with them and just may think that could be my problem. is there anything else that has not been said in this thread I could do to fix this problem? When connected to my computer it recognize it as a charger. I can't access my files from my computer to my phone.
any help would be very helpful! Thanks!
I'm having the exact same problem but now I tried to use Flashify to go back to original recovery instead of TWRP & now by recovery or boot IMG is screwed so it wont even boot to recovery..
It boots only to download mode & is not recognized by any PC we have, with every cable I've tried.. uhhgggggg
I was having the same issue. Here is what solved it for me:
• Disconnect the usb cable.
• Go to Control Panel\All Control Panel Items\Troubleshooting\Hardware and Sound
o Go down to device / hardware and devices – click on that
o Follow instructions to correct issues. This found I needed a bus device driver update.
o Let it update and once done go out.
• On PC - Go to Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings - go down until you get to the part that says "All Networks" ...expand the list by clicking on the arrow to the right. In this area you will see "Media Streaming" There should be an area highlighted in blue that says "Choose media streaming options" click on that. Make sure you "allow all" . Once that is done, click "ok" at the bottom. Plug your device into the usb and it should be recognized. Seems a recent Windows update has that filter off.
• Now, restart your computer.
• Use original usb cord that came with phone! Plug in phone then plug in usb to computer.
• It should recognize your device now.
I now have to restart computer every time I want to connect my device but it works.
Hi I am having that same problem with my note 4. It doesn't seem to be a pc problem as no pc at all none Nada recognizes the phone. Windows 7 to Windows 10. None. Used 2 workmates of mine who also have note 4s on my laptop and all the laptops i used i used their phine on itand they worked so blaming the pc seems to be out of the equation..your solution and all those settings have been untouched as it has all devices allowed ..... tried cleaning the connectors and also different oem cables to no avail ..The only thing I have not done is change the logic board
Hi I hope somebody can help me. I am having exactly the same issue. though I don't think its PC or Laptop problem. I have two Note 5 the other one is working just fine, while the other Note 5 that was just charging was connected I noticed that running *#0808# I can select AP and CP but MTP+ADP was not selected and if I try selecting the radio button I will be able to but after pressing Ok or Reboot it back to no selection at all. Which I observe on my other Note 5 that was working its always selected every time I run *#0808#.
One more thing noticed is that on the Note 5 that was not working I boot it download (ODIN) mode and connect back to USB of my PC and Laptop, I hear a sound (the typical sound in windows once you connect any USB device) though I cannot access it I am positive that my USB port on both device are in good condition and since it was detected in windows through ODIN boot mode I was under the impression that its a phone software/firmware related. Can somebody help me on this one? thanks

Enable AX88772 CHIP SET on Android 7.0

Hello,
I am not a developer but hope to get some support here as samsung has not been a big help so far.
Before updating Android versions my Samsung Galaxy Tab S2 SM-T713 would connect to Ethernet via the plugable USB 2.0 OTG Micro-B adapter.
It seems that the specific chipset used by the adapter is no longer enabled on this specific device, while I am told it is still included in all Android version 4 and up.
So my question is how can I enable the AX88772 CHIP SET in order to regain ethernet connectivity.
I tried going into dev mode and selecting "RNDIS Ethernet" in the USB configuration but that did not do anything.
Another issue possibly related is that when connecting the tablet to a Win 10 laptop it is not recognized. Here I tried many solutions including installing the media pack and other options available. No success. If this is an unrelated problem then I will post this secondary issue in another post.
Any ideas or suggestions would be greatly appreciated.
Thanks

Is there a reason why you need Ethernet rather than wifi?

Yes, we live in a house without wifi on purpose. My wife get's immediate headaches and body pains when she is exposed to a direct signal. After having been removed from it for several years in our house I feel the same way when it is on. Our house is wired and we use both ethernet over power or ethernet over coax depending on what room we are in. The last one works beautifully.

Dex Not Working

When I put my phone in the station it goes black and my tv does the same for a second. Than te tv says no signal. When I unplug my phone it says "samsung dex"... Is it because my tv has only 720p?
I'm having the same issue. The Dex and monitor worked fine with my S8+ but just got the Note 8 and it's blank.
Nothing

Nothing happens for me and ive tried 2 dex stations. Could the dex software be missing from my phone?
I have used a generic USB-c-> HDMI/USB-A/USB-C adapter without issue. It was finicky at first. What are the origins of your phones?
I believe Dex actually specs 1080p as minimum requirements.

I have used an old Dell 19" 4:3 display. It's easily 10years old. It letter boxed it, but still worked.
Did anybody find out what causes this as I have the same issue with my note 8, tv says no signal but when phone removed from doc it says samsunsung dex?

I was having problems with the DeX not detecting and also charging the phone every time I put it on, had to try 6/7 times, but it seems fixed after latest update

I had a Dex Station which would charge the phone and allow USB peripherals to be used but no video out or detection of it by my phone. I returned that one and bought another from someone else and it works perfectly. It could be a defective unit.
power supply can also be an issue. only my original note 8 works. I've tried with an s8 fast charger and it dont work. i have also tried with numerous 3rd party fast chargers and also did not work.( quick charge 2 and 3 compatible)
One other tip is, if you freeze or remove the Samsung Keyboard, Dex will not work. They are tied together.
After having issues with mine I found that little tidbit on line.

Problem with OTG&USB N950F

Hi everyone
here I've got a terrible issue with my note 8 and SAMSUNG USB OTG.
When I connect my otg and a flash memory to phone, nothing happens, unless you force restart the phone while the otg is connected. After booting I can access to my flash memory but after removing the otg and reconnecting it, again nothing happens unless force restarting.
I've tried everything possible. Downgrading, upgrading, 4 files rom, pit file, rom from different zones, but still have the problem. I have no other issues regarding the USB port and charging, fast charging, connection to computer and any other stuff works fun but this OTG.
I wanted to know if anyone have any solutions for my problem or if anyone had the same issue or not.
it is also worth to mention that I have not rooted my phone due to warranty issues, and for that I haven't tested any kernels.
thanks for everyone

That isn't right... As soon as I plug in my OTG USB key it detects it, no restart required.

allow file transfer .... possible
Nope, I have developer options enabled but debugging isn't on. never had to enable file transfer.
When I plug in the OTG device I see a usb icon in the notification panel. Swipe down and pick explore. Mind you it only opens in the stock file explorer, I did have another file explorer that picked it up too but can't think what it is and it has been lost myriad of other apps I test and play with...
Just be aware that it may take a few seconds to scan the device,depending on size, and then display the icon.

i know it sounds weird but from past experience flaky USB drives are more trouble than they are worth, from first hand experience i know patriot, corsair and sandisk work well as OTG drive
also you neglected to mention the file system the USB was formatted with, i believe only FAT, FAT32 and exFAT are supported

also possible that the phone doesn't like your OTG adapter. I bought a usb 2.0 to type C adapter which doesn't even work on the phone - when I plug it in usually the moisture sensor error comes up saying water is in the device and I should let it dry. Unplug the OTG and the error goes away.
So... I bought a USB 3.0 A to type C OTG adapter and that one works fine with everything I've tested (usb flash drives, keyboard, usb ethernet adapter, etc)
I believe the USB-C to USB-A adapter that came with the phone is actually an OTG adapter (tested xbox360 controller and keyboard)
I also believe that the note8 can host usb flash drive native (no need for OTG cable) as i have a dual head USB-C and USB-A flash drive which is recognized once the USB-C end is plugged in

Sorry to dredge up a semi old thread, but has anyone found a fix for this?
I'm having almost the same issue, I finally decided to try out the OTG adapter from the box and nothing works, it isn't even recognized. Tried ps4 controller, mouse, keyboard 2 different thumb drives. Can't figure out what the deals is.
Other than that pc connection seems to work and charging works fine. TIA
I'm having a similar problem. A month ago, used both OTG adapters (original from Samsung and a generic one) it detects my memory sticks as a hard-disk and was able to manage my files. But since a couple of weeks ago it does not detect them anymore. Is like it did not supply charger to them anymore. I have tried the USB debugging menu and no difference at all. Even I got back to factory reset expecting to solve the issues but nothing happened. The port as such is working perfectly because I'm able to charge through it. On the other hand, Samsung DEX is not working as well. It just charges the phone but never boot-up.
I'm just waiting for Oreo and hopes this will sort the problems out.

Seems to be a little bit dusty. Anyway, the other thing is that, when the Usb is detected it ask to choose between transfer files, images, midi device and so on, even if I choose "transfer files" mode it always get stuck as "charge connected device".
Hi i have the same problem... my note 8 can connected mith my notebook, but my otg with an usb stick cant recognize my note8. I test the same otg with usb stick on my friends phone example S8 and it detects promptly all.
I hope the fixing take not long time. I waiting for help. Greets
Well, adding one more case here, my native file manager doesn't recognize any memory connected via the original otg conector, but, using x-plore file manager, problem solved, as I use x-plore since my symbian days, I never gave this issue much importance, this problem was present also with my note 7

Sorry to dredge up a semi old thread, but has anyone found a fix for this?
I'm having almost the same issue, I finally decided to try out the OTG adapter from the box and nothing works, it isn't even recognized. Tried ps4 controller, mouse, keyboard 2 different thumb drives. Can't figure out what the deals is.
Other than that pc connection seems to work and charging works fine. TIA

This. I have exactly the same experience. I bought a couple of months ago a new Note 8, and finally decided to try the OTG adapter that came in the box. Nothing worked. I tried the adapter with a friends phone and it worked like magic (USB drives, mice, keyboards, controllers, etc.).
Would really apreaciate if anyone can provide help on this issue... Cheers!

Question [HELP] File Transfer to PC is impossible S21 Ultra

Hey guys, as the title says - I am having difficulty with transferring files across from my Samsung S21 Ultra to my PC.
I have tried:
- Developer mode, enable USB Debug
- ^ + set default debug to be FTP
- keypad *#0808# and select MTP+ADB
- In the notification bar, clicked the 'charging' notification (that sends me to battery, not to pick another option)
I do not have the original samsung cable as it was of poor quality and failed after 2 months however I am using Anker cables, I use them for file transfers on other devices such as cameras, VR headsets and other phones - they work perfectly fine on everything except my S21 Ultra. I have also tried different PCs/Laptops in case its a driver issue.
Phone specs:
Model number - SM-G998B/DS
Running the latest version of Android.
If anyone can help me, that would be great. I really don't want to factory reset as that means losing the things I want to keep anyway which is just a lose lose.
If you can't find a solution quickly right now, then just use this: https://play.google.com/store/apps/details?id=org.primftpd&hl=en_US&gl=US
FE Explorer can also do something similar.
Or, Samsung Flow or something else.
Also, are you mostly trying this on Windows or something else?
Ensure usb-drivers for Samsung phones are installed on your pc. E.g. by installing smartswitch on you pc.

No need to install anything.
If it's Windows, just go to Windows Update at some point after you connect the phone.
Click "Check for Updates" and/or go into "Optional Updates" and you'll find that the driver is waiting to be installed ON YOUR COMMAND.

Surely I wouldn't need an additional app to transfer files? I'm doing this on the latest build of Windows 10 21H2 and also on a Windows 11 laptop, my P20 Pro transfers just fine but the S21 Ultra doesn't read anything as something other than a charger.

Do you have super display installed? I had an issue where I had super display installed and could not connect my phone for file transfer until I turned the super display service off in my services on Windows.
I am having the same issue and as I can recall it was after the recent update strange may be.
Open driver manager from within control panel, right click on portable devices and update MTP driver for Samsung phone. Press allow on your phone and you should be good to go.
I'm using Solid Explorer over WiFI, no issues
If you're using a corporate windows you need to install the media feature pack. Otherwise just try a different cable, some don't work. I had the same issue when using my old huawei cable, used the one that came with s21u and was fine.
Try disabling DeX in the phone settings. It worked for me..
Just a quick question guys, does the S21 Ultra come with a USB 3 data speed cable or is that something I'd have to buy on amazon etc. Thanks.
