Describe the bug

Like in title, 2020 mac m1 air. Downloaded openMTP and was working great for weeks.. Today transfering some mp3s and it is slower than passing them via bluetooth. I tried several different cables, and cannot think of any reason why. It just became painfully slow.. Freezing after 9min transfering 350mb of mp3s

Expected behaviour

Was a lot faster befoew

Current Behavior
Its insanely slow

What is the version of the OpenMTP that you are facing this issue?

[Leonidos]

I downloaded the latest version today via brew. And I got very slow transfer speed too. 200mb audio book was copied for over 15 minutes. Like someone added delay between files or something.

mbp 16" m1 monterey 12.4
samsung note 20 utlra Android 12
OpenMTP Version 3.1.15 (3.1.15)

On old mac I had nice speeds.

[ganeshrvel]

The M1 support is still in it's alpha stage and i am working on it.

You can download the alpha version of m1 from here: #244 (comment)

I am also experiencing this, progress display shows a 13MB/s but a 14GB transfer is at around 10% after more than 1 hour

[landry314]

i just downloaded the newest version myself and copying 7000 files from my pixel 5 to my mac was fast, very fast, but now i am trying to copy them back and it is INCREDIBLY slow. this will take days? what is happening?

[landry314]

This project hasn't been updated in a year. The file transfer is not working right.

I just figured I would use the terminal with adb and it works so fast!

If anyone is reading this, to copy a folder to your android from a mac and PRESERVE DATES (which is so important when copying images or your gallery will be screwed up), turn on ADB (in developer options, "USB debugging") then open the terminal on your mac and type this:

cd to YOUR platform-tools directory

then

./adb push SOURCE FOLDER ON COMPUTER DESTINATION FOLDER ON ANDROID

to use pull dont forget the -a flag...

./adb pull -a SOURCE FOLDER ON ANDROID DESTINATION FOLDER ON COMPUTER

Folks,
I am reading your comments. My work has been keeping me busy and now I am looking for a new one. The apple silicone support is almost there, I need to figure out a few things. Let me assure you that the project isn't dead and hopefully there will be a new pre-release pretty soon.

Regards

[ganeshrvel]

Folks, I am trying to figure this issue out. I will make the beta release for Apple silicone soon and hopefully this should get sorted as well.

1. What OpenMTP, Android and macOS are you people on?
2. Please download these OpenMTP versions and let me know whether the file transfer speed is slow on all of them
   a) OpenMTP-3.1.0.dmg
   b) OpenMTP-3.0.0.dmg
   c) OpenMTP-2.4.4.dmg
   d) Apple Silicone: OpenMTP.app.zip

Also please note MTP protocol in itself is a crappy implementation. The file transfer speed tends to get slower after a period of phone usage.

@landry314 I am aware of the Dates and the other metadata preservation issue. I am looking into it as well.

[landry314]

the date problem is also in android file manager which is why i need to use push for most folders. quite surprised google coded mtp so badly.

[Polovinkin]

Arrived to this thread via Google, was really surprised just like @landry314 when I had quite fast speed of loading of my photos from my S23 Ultra to my M1 Pro Mac, but when I'm trying to load something back, it's incredibly slow, so 10 months passed passed and this still wasn't fixed as it seems? :(

It took Open MTP almost two minutes to transfer 8 Mb worth of photos to my Android... I just can't understand why would it load it with a speed like that...

And what about metadata preservation? It's the main reason I'm trying to transfer some photos from my old iPhone to correctly transfer dates from exif's.

@PhilipHoltzman did you notice any change for you after this time?

[landry314]

this app is slow and deletes metadata. there are other better ones or just use push and pull commands in terminal with adb

Which do you use?

[Polovinkin]

@landry314 which apps are you talking about in your comment?

@ganeshrvel is it really still not fixed after months and months?... :)

honestly, all the apps dont work right.

i just use adb push and pull now. it is fast and with the right flags it preserves dates...

in a terminal...

cd to YOUR platform-tools directory

./adb push 'SOURCE FOLDER ON COMPUTER' 'DESTINATION FOLDER ON ANDROID'

to use pull dont forget the -a flag to preserve dates.

./adb pull -a 'SOURCE FOLDER ON ANDROID' 'DESTINATION FOLDER ON COMPUTER'

[Polovinkin]

thanks! But as I understand, adb push (and I need to transfer photos from Mac to Android) do not preserve metadata, there is no -a flag for adb push. Did you figure out the way to preserve dates when moving data TO Android, not from it? :)

[ganeshrvel]

Hello everyone,

I'm planning a lightweight and modern rewrite of the app in the near future. This will be a complete GUI app overhaul from the ground up. In the meantime, I'll attempt to find a solution for this issue.

i just read online to use this:

adb push --sync

anyone have luck?
