OTG File Transfer Slow - Pixel C Q&A, Help & Troubleshooting

Has anyone transferred files over USB OTG? It seems painfully slow:crying:, like lower than 500Kb/s. It makes copying larger files, such as videos, almost impossible. On a regular computer, speed of copying files over USB ports is at least 5Mb/s. Is this normal?

[Q] Slow usb transfer speeds fix yet?

I just went to transfer some files to the Fire when I remembered how it barely goes usb 1.0 speeds.
2mb a sec for a 300mb video file is obscenely wrong.
Last I recall the wifi speed was actually faster.
Is there a software fix or something yet or still stick with the wifi xfers?
It seems a lot peppier now. It wasn't so sluggish to detect the device when I connected it and I just got about 20 MB/sec on a >700MB file transferred via USB.
Edit: But transferring the OTHER way (from my computer TO the KF) I just got... about 2.3 MB/sec on a file less than half that size. Weird.
I think it's somewhat better on 6.2.2. USB mounting the sdcard partition dropped from 10 to 2 seconds for me, and USB transfer of a ~260MB file is now at about 10MB/s. I don't recall the original speed but I know it was quite a bit slower.
Tom's Hardware has a very nice but highly technical. explanation about why the transfer speeds are very slow.
http://www.tomshardware.com/reviews/amazon-kindle-fire-review,3076-11.html
With 6.2.2, it's still too slow to transfer files to the device.
I understand the why, but would love to know know the "when" it will be fixed.
My ipaq transferred faster on compact flash cards.
I didnt notice this on 6.3 firmware
But since I changed to CM7KFire it's been ridiculosly slow... do any of you out there with stock software 6.3 got fast transfer speeds?
You can get 5-6MB/s if you use adb push.

How to transfer files from Epic Touch internal SD?

I am trying to save the contents of my internal sd card to my computer and/ or my external hard drive that is connected to my computer. I am using a Windows 7 PC, a sturdy BlackBerry and a Western Digital cable and I have the D-710 drivers installed. I am getting no where. Files easily copy from the external sd card to the external hard drive but I can't move folders from the internal one. I tried MTP and PTP in the USB PC connection menu. When every I attempt to transfer large files or multiple folders the computer gets stuck on "calculating transfer time" and when I move smaller folders once the move is complete there are files/ folders missing.
Is it my phone? I've been using phones as mass storage since my PPC 6800 and I've never had these issues before, but I've never had a phone with an internal sd either. And yes I searched google and this forum. Thanks in advance!
If you have drivers installed on your PC and you can see your phone in " computer" ,you should see two drives, one going to be SD on phone other external SD. Just make folder and drag and drop.
As long as you have drivers installed for Samsung, you should be OK.

Thanks for the suggestion it is greatly appreciated but that is what I did. I tried two computers and the transfers failed on both. Maybe because it's about 10 gigs I really don't know.I'll try a newer computer and see if that helps.

Are you sure the cable is good?
Try breaking up the transfer into smaller sections. Like grab 4 or 5 folders and drag and drop at a time. Also try different USB ports and different cables, sometimes the phone is picky about what you transfer over. Make sure you're using a usb2.0 or higher port, on desktops those are typically in the back of the PC, laptops usually only have 2.0 or higher ports because they don't have as many, and some newer PCs have all 2.0 or higher ports, but some cheaper desktops still have 1.0 ports in the front to cut costs

Thanks for the help.. I figured it out..
The problem was the Android folder. Some apps have ridiculously long file names several folders deep. Windows freezes up when the file's name and location become too long. Thanks for the ideas it was driving me crazy lol I think I may have to write the devs and let them know to clean it up lol.

[Q] Sd Card transfer

Hi this may have already been answered but I'm having trouble locating any information on it.
When transferring from my laptop to my tablet, some of the time my files transfer fine while others won't.
Now before someone says the formats are different. I have made sure the file formats are the same.
I have included a picture of what is happening.
I have reformatted the sd and managed to get a few files on, then the same thing happens. Even previous files which have worked before come out the same way.
Please help me its doing my head in.
Can you explain what the photo is showing, It looks like you are trying to play a movie in some strange multi-windows player that i do not recognise, maybe even a streaming movie service, not copying a file from your notebook to your tab.
The only problem i have see is transfer times can me quite long, though windows transfer optimizations may be off by a bit, my brother-in law was copying a load of movies to his new 128gb, and he was getting estimates of 14 days copy time, for big transfers i take out the microsd card and use an adaptor and plug it in my notebook.

Pixel and USB OTG - FAT32 vs exFAT

Has anyone else tried using the included USB-C to A adapter to mount a flash drive? The phone recognizes it fine, but seems to only be able to read FAT32 formatting. I have other Android devices that can read exFAT just fine via an OTG cable. One of the reasons I was ok with getting the Pixel XL which doesn't have a MicroSD slot is that I assumed I would be able to hook up a flash drive if I wanted to watch some larger video files. I often have video files that exceed the file size limit of FAT32, so that format is not really an option.
I didn't realize the USB-C to USB-A connector was USB OTG. Thanks.
I tried a thumb drive first formatted to FAT32. It worked fine and I could access the files on it. Then I reformatted the thumb drive to exFAT, copied some files over to it, and then tried it. Nope. I remembered that I bought a file explorer for my N5 (it wouldn't mount the thumb drive) to allow USB OTG without root. So searched through my apps and found it....... USB Media Explorer https://play.google.com/store/apps/details?id=com.homeysoft.nexususb.importer&hl=en It is a paid app. It advertises FAT/FAT32, NTFS or Ext2/3/4, but it did work with exFAT. The interface wasn't the most intuitive. I went to folders and saw the music there. It was easy to play the music on the thumb drive. It took a little bit to figure out how to copy a song to the Pixel memory (have to select the song and then a copy looking icon pops up). I haven't figured out how to copy a complete folder yet although it must be possible. There were a few other apps on the Play Store that looked similar. I only tried this one since I had previously purchased it.

Thanks, that app did work to be able to view the files on exfat formatted USB drive. For some reason playback of a video file is really slow (buffers a LOT) if playing directly from the drive. A bit odd, since copying a file to the phones internal storage didn't take too long, about a minute for a 500 Mb file. Not anywhere near USB 3 "normal" speeds, but not terrible. I found one other app on the play store that was also able to read the USB drive, but had the same performance. I will test formatted as FAT32 later and see if there is a difference.
This non-supporting of exFAT clearly shows Google is tying to push us to store everything about us on the Google Drive so that they can monitor everything about us... Is your thumb drive usb3 compatible? If so and you're not getting the 'normal' speeds, that's another sign. We better watch out. They will eventually force us to use their proprietary app like iTunes to transfer files between Pixels and PCs.
Seriously, though, I need a way to quickly sync my photos and videos from my DLSR.

Actually a minute for a 500MB file IS a lot.
Which USB pen drive is it?

Agreed.
My tests showed a similar result with Kingston 64GB Data Traveler Micro Duo as well as Sandisk Ultra 64GB using FAT32, exFAT, and NTFS. For comparison, my Nexus 6P transferred the same file approximately twice as fast.
I was a little disappointed by the lack of native support for formats other than FAT32 and this issue makes the file-size workaround less than desirable. Otherwise, my pixel xl seems to perform as expected.

Struggling with this as well, I foolishly bought the 32GB Pixel XL and constantly run out of space so for large file storage I bought a 64GB Sandisk usb drive (3.0, one of those tiny thumbnail sized dongles) and it works but the transfer speed is maxing out at 2mb/s! It takes around 30 minutes to transfer a 2GB file; I manage but it's pretty unacceptable for a 3.0 device (using the Google provided C to A) and it drains the battery like mad!
Any more thoughts on this? I'm struggling to find an answer (read: fix).
Thanks friends,

I did some more testing now that Google has had a year of software updates. Unfortunately, even on 8.1 December update, it seems FAT32 is still the only supported format, and the speeds are just as slow. I could only get about 15 Mb/sec. Thats using a high end aftermarket USB-C -> A adapter, and a 128 GB Sandisk USB 3 memory stick. This same adapter and memory stick can transfer well above 150 Mb/sec on a PC.
exFAT is a proprietary file system created and owned by Microsoft. Google did not pay Microsoft for the use of it on Pixel phones.
So exFAT can technically work if you Install Solid Explorer (free trial then $2 lifetime fee InApp Purchase, in my opinion well worth it as it's Solid) and their Solid Explorer USB OTG Plugin. Full Read/Write access for Fat32 and exFAT, NTFS Read only support. I actually loaded up my 64 GB Sandisk Extreme Flash Drive (exFAT formatted from Windows 10 pc), and took it on a trip with me to Disney World, so I could load movies and unload pictures of the family. I do have a 128GB Pixel XL, however I have a huge music collection I prefer offline, and ironically a lot of DayDream VR Experiences (it is space-consuming for offline copies such as Discovery VR etc, so those add up a Lot, but it does make for best experience as it is very heavy bandwidth dependent over wifi).
The USB 3.0 in my opinion doesn't exist for OTG, or at least with this adapter, I do have another adapter I think I'll try in a moment. However what I want to say is this flash Reads up to 245 MB/s and Writes at up to 190 MB/s, I usually average 100 - 200 on my pc. On this flash drive, just copying a file to phone from flash drive over exFAT apparently is limited to 0.5 MB/s. In other words it's going to take nearly 2 hours to copy over a 2.5 Gb file. It can still copy over with screen off, but I was thought it was ridiculous how much battery would be consumed and kept thinking if issue was UFS storage or drivers. I am on Android 8.0 November, will update to 8.1 clean install this week when February 2018 comes out. This actually did cause an issue for me using the original usb c to a cable on my pc, where it doesn't work and I have to use a specific usb c to a (2.0 version), which is still much faster than this. That issue though is because I 'dirty flashed' 8.0 over 7.1.2 without wiping. Only bug so far from that.
Not sure if the app was updated to support it or if Android 8.1 now supports it natively, but I'm able to access a flash drive via my phone using the adapter and File Manager by "Flashlight + Clock".

Are you sure? I just tried it and it told me it doesn't support exFAT
Hi could anyone give a clear answer about use of OTG with Google Pixel XL: I read all about Google not supporting the exFAT format (someone said because they wouldn't pay Microsoft to license the tech), and that Pixel users are stuck with super slow transfer speeds, and file limitation sizes of FAT32. Someone else mentioned somewhere about Host Mode, and I'm finding it way harder than seems logical to get some definitive answer: If I can't get fast OTG transfer speeds with the Pixel, then I have to pass on its high quality camera and go with an inferior phone that has microUSB.
Can someone help me out with this please? Thank you much.

Try JS USB OTG app. I use this to play big video files with MxPlayer in SW mode, without rooting and the app doesn't seem to stream video like other apps, you can go back or forward without any problems.
it always seems when there is any issue and someone ""tried"" an app and blah blah .. its always an app that needs to be PAID TO USE !!!! crack me up just makes me want to find the paid ""free"" version through a google search

Question Problems with USB storage?

I have connected a usb-c enclosure with NVMe to my new P6Pro. Everything looks okay until I try to transfer certain files (and/or transfer a bunch of data). One that I keep having issues with is a TitaniumBackup file, about 200-300mb.
All my other Pixels (3XL, 4XL) transfer the file just fine. Transferring between a PC & the P6P works fine (both ADB & file share push from the PC).
At first I suspected that phone doesn't provide enough power to the OTG, but it's happening very consistently with certain files, which should take ~1sec to transfer at USB3 speeds...
Wondering if it's my device or a more common issue.
Interesting. I don't have any external NVMe adapters. I do use an "old" USB-C hub that includes a Micro SD slot, and I regularly copy my music from that to my P6P's internal storage, but none of these files are likely that big (it's funny calling anything less than many GB big, but I guess all music, even my preferred format FLAC files, are still reasonably sized). I transfer a total of ~400 GB of music. I don't have the same issue but very different enough circumstances, so I'm not revealing any very helpful information.
Seems like this has to do with .nomedia file handling
0-byte .nomedia is apparently invalid now -- and if encountered, something bad (like this) happens

Hmmm, I use .nomedia files extensively in all of my music's deep folder's structure, but I create them with an app that does it all at once and haven't copied those files to the source locations on my computer hard drive or the duplicate copy on Micro SD card. I'll set a reminder to run some experiments when I'm in front of the computer tomorrow and report back.
Of course, it could be specific to NVMe drives, or particular types/technology of NVMe drives, and I won't be able to confirm either of those through an adapter, anyway.
Okay, did some digging. First, back when I used to manually create .nomedia files (or use an old app to do so), they were of course zero-byte (empty) files. This app Nomedia, although slow, does work for me, and apparently creates the files with various small byte-lengths - the contents of which are merely the text of the path it put them in.
I also learned that they only seem to be necessary at a root level to completely exclude everything underneath it. I didn't remember that was the case. So I only have six .nomedia files in my 400GB+ of music files folder structure, and I'll just keep in mind never to create my own, or if I do, to always have something in the file so it's zero-byte length. I can only assume the developer for that app knew that zero-byte .nomedia files could cause some problems.
