Problem using Samsung T7 SSD with N20 Ultra 5G - Samsung Galaxy Note 20 Ultra Questions & Answers

Newbie here, sorry if this is in the wrong place.
I recently purchased a Samsung T7 SSD specifically to use as extra storage for my Note 20 Ultra. Upon unboxing, I noticed that when connecting drive to phone with supplied USB-C to USB-C cable, the drive will not power on (no lights on drive). My phone will not recognize anything is connected at all. I then connected the drive to to my computer and it instantly powers on, I quickly unplugged it and connected it to my phone and the drive lit up and connected as it should. After unplugging and waiting 10 seconds or so, and reconnecting, nothing happens, no lights, nothing. I can even connect it to the usb-c input on the media center of my vehicle to power it on and then quickly plug it up to my phone and it will work fine.
I did do a restart of my phone with the drive plugged in and upon phone reboot the device was powered up, but it still will not get any power from port upon cold connection.
Any help or tips are greatly appreciated.

Did you try to check the cable, because something similar happened to me with a pny external ssd disk and the cable was the problem

Yes, I tried several other cables with no luck. They all do the same. The cable that came with the drive works fine in with every other device I plug it into. Is there a setting that toggles power output from the phones USB-c port? It seems like the phone is not supplying enough power to the drive to start it up.

Nexus 5 Touch issue when connected to PC

Hi
I have been having this issue for sometime now. I connect my Nexus to my laptop using the USB cable, and most of the time the screen starts acting up. Touch calibration is all wrong. When i click something, the actual button that is clicked is totally a different one. And sometimes it activates stuff on its own.
I have tried several stuff I found on google. Some said it had something to do with my home electricity not being grounded. I checked. It is grounded. Tried everything from flashing new roms to freshly starting from stock! Nothing seems to work!
Its like this thing have a mind of its own
Hi, if you use stock wall adapter, it's working correctly? Usually that is some kind bad electricity problem or that device where you plugged it causes problems.
Check usb cable. If it's not happening on LG cable and LG wall charger than it's your usb to pc cable problem
PS check other usb port and cable

1TB portable drive keeps disconnecting

Good morning all,
I have a 1TB USB 3.0 WD my Passport portable drive that I have always used on my LG G3 connected with a OTG cable. Works flawless. When I plug it into my S6 in never settles in and connects. Just keep connecting and disconnecting. It's almost as though the drive is not getting the power necessary to start up. I can see the indicator light up and here it spin but then it shuts off. Over and over. Any one else with similar issues?

Samsung Galaxy S8 OTG (USB On The Go) USB Host

How do I fix my otg issue? It connects but says charging connected device. Even with a ps4 controller at 100%. When I go to tick the option to switch it acts like it does then it goes back to saying charging device. I'm on stock rooted and tried this on all the current roms.
Hello,
I have had a good time using a usb c stick with exFAT to transfer files to and forth from my s8+. In the holidays I had water over the device and after the usb liquid issue. After some days it went away but now no stick , be it my usb c one or others with the OTG connector , is connecting.
Problem is that through cable phone connects to the PC ( although slower than usual ). Also charging first detects a fast charge through original charger and in 2 seconds drops to normal charging. For a while I have reset the device with the stick connected and it got read but after unplugging direct or unmount would
not reappear at a second plug.
Any ideas , this is driving me crazy ( even did a full reset to no avail ).

A8 (2018) USB connection to HDD or memory stick

I've been having trouble connecting my A8 via OTG for some time. I have a Syntec USB-C to USB adaptor, which allows me to plug usb to the phone via OTG. However, this doesn't work any more (it did originally).
Sometimes when I plug in a device, the phone flashes device connected / device disconnected, sometimes it says usb charging, sometimes it doesn't do anything. I've tested the adaptors connecting them to the thunderbolt port on my desktop, and they work perfectly.
I've also tested the adaptor by using it with a USB-C to usb-a cable to connect the phone to my computer. When the adaptor is on the phone end, it doesn't do anything, when it is on the computer end it works perfectly.
Is there something I can reset or change on my phone to get this working?? It's driving me crazy.
Thanks,
Nick

plug your phone into your computer and change the connection type to MTP

Oops... I think I just bricked my new Xperia 5 ii...

I bought this new phone on Nov 6. This is how I bricked it....
Xperia 5 ii won't work with Type-A to Type-C cable at all and my computer just don't have a type-c port, so I tried OTG with USB disk. Although the disk was mounted, I couldn't find it in a third party explorer (ZArchiver/SolidExplorer), however the built-in explorer couldn't copy the file into the phone somehow, so I tried to reboot the phone, aaaaand it is bricked...... Push the power button for a looooong time, no response. Plug in the power cable, no response, LED not even lighten up.
well I guess OTG is a pretty dangerous feature since it mess up with voltage in the power module, and two of my previous phones died of power problems, namely Samsung S2 and Xiaomi Note.
Is there any way to confirm whether it is a dead brick before i go and return the phone?
Not the solution, but mine works fine with usb a to usb c cable connection to my computer. Had been using that for transferring old data into it.

oh I should change my description into "my Xperia 5 ii won't work with any of my A to C cables" lol, maybe they are too old to be compatible? no idea though
Have you tried pressing power button + volume buttons for 30 seconds?
Also OTG should only be able to charge another device, so you might be lucky and didn't fry your Sony phone.

!!!! long press power + volume really did work XD my phone vibrated 1x following 3x then I could power it up again ~~~
after looking up on Google i found that power + volume up would force shutdown the phone, which quite surprised me because i've been using android since 2012 and somehow never heard of this before. I know that long pressing power button would force reboot though, but it never came to my mind that there could be a way to force shutdown.
Thank you very much! That saved me a lot of time and saved me from a bad day lol

This is odd since my works with Type-A to Type-C cable. It's a short Sony cable which i received to charge my WF-1000XM3 earbuds.

I was online with Sony Support this morning because my Xperia 5 II had shut down, wouldn't power on, wouldn't charge. In my chat we the support guy he said you should not charge your phone from a laptop. After 12 hours of panic my phone showed a graphic for zero battery. I plugged my cable in and got the red LED light. Phone went on and fully charged. I have to idea what happened but don't try to charge with a Thunderbolt4 cable.

I had my Xperia 5 II for a year now. 70% of total charging was done using USB C to USB C cable from a laptop Thunderbolt port.
I have no idea why Sony has autistic support that scares users. I almost charged my Xperia from any USB socket I could find (be it either A or C) and it still runs like a charm.
