[Q] Cannot transfer file > 4GB via MTP

Just got my nexus 6 yesterday, I've downloaded the latest Android USB drivers as well as the SDK and the phone is successfully recognized.
I have a problem when transfer a file larger than 4GB (eg. HD videos) from my windows laptop to my Nexus 6 via MTP
It just hang and not responding. No issues if file size is less than 4GB.
(my device rooted and non-encrypted btw)
I think it's not the file system problem as it was ext4 and I can have a single file that larger than 4GB available in the device.
For now I just fix it by zip the file into several parts, transfer to n6 and decompress it, Which is really annoying.
Tried some wireless transfer like AirDroid, SuperBeam but the speed is not satisfied, it takes about half an hour for a 4GB file
I think the problem is MTP. Is anyone else facing this issue?
Any Solution? Please Help.
Thanks

why are you transferring those files to your phone? they are files that need to be installed in your computer/laptop.

I usually have boring times when travelling to my workplace (It takes so long because of traffic jam in rush hour)
I think it would be great to watch a movie in n6 as my laptop is too heavy to bring outside. But most of HD movies are >4GB.
Do you have the same issue? I wonder is it just me facing this problem.

i believe that you are limited to anything under 4GB for a file transfer. of course you can try adb sideload or adb push.
movies i understand, but why transfer the sdk and drivers to your phone is what i dont understand. and i never installed the whole adk, just adb for dummies, which was only 36mb.

Thank you for the suggestion, I'll try:fingers-crossed:
Sorry if I make a misunderstanding in my words. I didn't transfer sdk to my phone,
I just give a background that I've installed all the SDK and drivers to clarify that my device is successfully connected and recognized.
Just tested transferring the same file with my friend's Samsung Galaxy S6 and Nexus4( KitKat ParanoidAndroid ROM )
And things are working fine, I can transfer the file(~6GB single file) to both S6 and Nexus4 without any problem/hang using MTP.
So I think the problem is not MTP anymore.
Is the issue is about N6 file system or is it just my device having this issue?
Any help?
Thank you.

Can´t write to system

Hello all,
i have 2 Sony Xperia V mobile phones and i installed the same rom on it (CARBON-LP-5.1.1-UNOFFICIAL-20150812-1159-tsubasa). With one of both i haven´t any issues but with the other one i can´t write to the system folder. I tried ES File Explorer to make the system RW. No error message follows but i can´t write to it. I tried the Mount app and the same result. No error message but i´m not able to write to the system. Apps like Gallery can´t work but no external Storage available.
I installed both phones with the same kind of installation. One works fine one not.
Can anyone help me to find the solution?

Help.

So i installed Havoc OS on Mi A2 but now i cant seem to take screenshots or download from broswer it just says no memory also if i go to files everything in Root Folder is encrypted? random letter capital and lower case. any fixes?
Did you format data prior to installing ROM?

Question [HELP] Can't open pdf and other files on some apps

Hello people it's just to report and see if any of you have faced a skmilar problem and how To solve it.
The main problem is that all files pdfs, jpgs or any other that are sent to me via WhatsApp it's impossible to open with any app. All apps say the file is corrupted or something like that. The same happens with Edison Mail (app) I use it to have all my mails synced, but the same happens all mails that contain attached files are imposible to open the external apps to open pdf or image files say it's impossible or file corrupted.
Nevertheless, and the main thing is that those files are NOT CORRUPTED whatsoever, if I look for the files on the internal storage and open them with any of the apps that said that the same files were corrupted, the files open without any problem.
I was going to reinstall WhatsApp, but in the end I didn't because it's really time consuming to make a backup and because I realized it was happening with other apps (probably with others I haven't come across).
I have checked permissions, disabled /enabled them but with no luck.
Any thoughts or similar experiences? Any workaround?

This problem isnt occuring for me. It opens for me fine. Maybe it could be an issue with the pdf reader?
What do you mean when you say, it is impossible to open pdfs in external apps?
Im assuming you have tried different pdf apps as well? Try opening the file from the pdf app itself, as in navigating to the file from inside the pdf app, rather than opening it directly in whatsapp.

Sorry if I wasn't clear enough.
If I open the files directly from the pdf reader (I've used several, acrobat, xodo, drive, onedrive, etc) or opening the files from a file explorer (solid explorer, xiaomi file explorer) they open, they are not corrupted.
The problem is when I tap on the attached file on the whatsapp chat or on the edison mail (app) The prompt to select an app to open the file shows up but no matter which one I select it will FC or say the file is unreadable or corruupted (depending the app). That is why I believed the problem was regarding some permissions in whatsapp or edison mail, but I've enabled and disabled them with no avail.
If you google this problem, hilariously you can find a very similar one on an Adobe forum but of course there's no solution because the adobe won't provide a solution that is not directly caused by their apps. The only good comment there is that apparently it's an andorid 11 problem on MIUI devices.
Some mention to disable MIUI optimizations, which I've already tried enabling and disabling because I usually have them disabled.

Yes, it certainly seems like an miui problem or the A11 problem. Okay, do one thing, try opening the pdf file via chrome browser, or any other app, maybe gmail app.
Also, before you do that, download matlog to log what happens, maybe we can try pin pointing the issue.
If its just an app thing, then maybe reinstalling should fix it. But i doubt it is. And the only real possibility seems like reinstalling the rom.
Heres a suggestion, since we dont have twrp yet.
Download the latest full rom, a few issues happened to me earlier, when i installed miui in one of the incremental updates.
So, what i did was, downloaded the entire recovery rom (not fastboot) and just updated the system via system update by locally installing it.
Just google how to local upgrade on miui if you're not clear about it. As i wasn't since this is my first miui phone.
This would essentially dirty flash a stock rom, and should iron out any issues without having to reset the phone.
Is your MIUI optimisation option disabled in the developers options? If so, try enabling it and try to open the files again.

Here are the logs. Actually by doing so, I discovered that also sharing a zip file from the matlog to any app to upload or share it (whatsapp, gdrive, onedrive, etc.) also resulted in an similar error (this part is not included on the logs).
The logs include trying to open one file in two different apps. Gdrive pdf reader and Xodo.

Actually I hadn't tried that, Just did and leaving MIUI Optimizations enabled makes the problem disappear, in fact, the promt to select the app to open the file is different.
But what if I want to leave MIUI Optimizations disabled?

I don't think there's a solution for this. I think the best workaround for this problem would be switching to Xiaomi.eu rom (since they have MIUI optimisiation disabled by default) but it's still not released yet.
I could be wrong though.

Im assuming the miui has its own code for the app selector and the underlying android 11 app selector code is disabled. Probably to speed up the process of switching apps. Maybe if there is a way if you can enable the original android 11 code for it then you could disable the miui optimization setting. But then, if this is just for the app selector, there could be other underlying issues, that you might have not have experienced yet where miui uses its own implementation and has disabled the original android implementation. I wouldnt recommend that unless you decide to switch roms to the EU version for this specific issue like @brzi6 mentioned but i think theres no point as it could cause other location based hassles.
Firstly, miui optimization is garbage anyway.
Secondly, the problem is with app permissions. If you can get your pdf viewer of choice to have access to your file system then all will be well.

Well I currently am facing this problem on an unrooted stock ROM. [MIUI Global 13.0.1 Stable]
So i doubt if this is a ROM problem. And if it is, it exists in the stock ROM too.

can you explain the problem you are facing in details
what are you copying ? numbers and sizes
where are you copying from and where to
being on miui stock and having this issue may tell it is a hardware problem
try copy from internal to a folder in the same storage and report back

Well there aren't much details to be provided. Was just moving some images from the WhatsApp data in Android folder onto my laptop to free up space. The sizes of all of the pictures were < 5 mb. Was moving 2-3 at once and took 30 seconds.
Also I was deleting some audio folders of WhatsApp too which took ~30s to delete a folder with just 1 audio file, and this happened multiple times.
Not sure if the problem is with my mobile or my laptop, but is definitely a lot lot slower than expected.

well that another thing and here we can't be sure who or which to blame maybe usb port maybe data cable not necessary the mobile itself
my problem was when copying or mpving from here to there in the internal storage itself
or when deleting also
while the most annoying thing i forgot.to mention earlier is opening a folder with much files inside like 100 image pr tens of apks it tooks a lot of time to open the folder and i have to wait some seconds with the rotating loading icon which is really frustrating
