[Q] eMMC read speed is really slow? Wired or FTP - Galaxy Note II Q&A, Help & Troubleshooting

I've had my Note 2 for a few months now. Haven't rooted it yet, but I plan on it. Coming from Gingerbread on an EVO OG, so I'm still new to Jelly Bean. I haven't used an SD card yet, I'm just working with the builtin storage, eMMC is what they call it, right?
When using the builtin storage with Windows 7, it shows up like a media device, which changes certain things on how I'm used to accessing it. For example, you can't view thumbnails of the files on the device (which seems silly to me), and the system changes the effects of a double click (preview vs open). My beef is really the read speeds are horribly slow. Something to the order of 1-5MB/sec or so on a USB 2.0 port.
I downloaded and installed FTP server ultimate because of a review I saw here:
https://www.xda-developers.com/andr...id-with-ftp-server-ultimate-xda-developer-tv/
and it works great.
Except I can only get 1MB/sec or so while downloading from my PC :/
I thought maybe the eMMC was slow, so I started googling and eventually found this:
http://forums.androidcentral.com/samsung-galaxy-note-2/227271-note-ii-sd-card-read-speeds.html
which shows that the eMMC is supposed to be plenty fast, at least locally.
Should I be seeing faster transfers?
Are there hacks or mods to increase eMMC read speeds?
Is the OS throttling me somewhere?
Is there a better file transfer solution or mechanism?

I'm getting really slow speeds from my W7/W8 share (800kb/s max) as well compared to the speed I get from internet (7MB/s when testing).

[Q] music stutter

I am having a music stutter issue. I have read lots of related threads, but haven't been able to find too many (any except this one about sdcard problems: can't post link because I'm teh nub sauce, but the title is "Lingering EVO issues (SD Card, Camera, etc.)") that talk about the problem on the EVO. I am thinking it might not actually be a bug and could just be the fact that I have a crappy SD card (the one that came with the phone). I ran SD card speed test and got
10 MB/sec read
2 MB/sec write
which fits with the fact that it is a class 2 card. I do not get music skips that often, but get them particularly badly when I am downloading on 4g (which I do a lot using subsonic). I also think it could be because of a slow SD card because I have had problems with 720p video getting corrupted which apparently is a common symptom of slow SD cards. I do have 7 full homesceens with about 5 widgets. When music is skipping the whole phone is going laggy and slow, so maybe its processor speed? IDK. Has anyone else had this problem on an EVO?
Please halp.
Running newest FRESH rom, but it happenned on stock as well (actually one of the reasons I rooted).
Try upping the cache size to unlimited on subsonic. That did the trick for me.
If you ever want to delete music, just manually delete the subsonic folder using Astro or what have you.
But what about the fact that sometimes the normal music player will skip, again especially when I am using 4g? Is it possible that 4g is downloading so fast that my SD card is not capable of reading/playing 320 kbps mp3s and downloading on 4g at the same time? 4g speeds are about 2mbps (.25 MBps) and my write speeds are 2MBps (16mbps) so this doesn't seem like it could be the case, but maybe reading/writing at the same time significantly slows things down? I dunno.
Did you ever get stutters in the normal music player? Did it skip A LOT when you had a 4g connection?
I live in an area with no 4G coverage, so I doubt that's it. When I read your title, my first thought was "I bet he has subsonic installed".
I haven't read anything online about this, but I also came across this stuttering problem. It pissed me off to no end. What I ultimately noticed was that all the "stuttering" music was at some point downloaded via Subsonic (even if it is played with a different media player - Cubed in my case). At first I thought it was something to do with the data connection, but then I became suspicious of the cache size.
I suspect that Subsonic downloads the tracks as long as the cache is not full, but then if it becomes full halfway through downloading a track, it corrupts the mp3 with a skip (perhaps while it deletes another track in the cache).
Regardless, increasing the cache to unlimited is what fixed it for me. Give it a shot.
Btw: Using CM6, for what it's worth.
I found that this was happening on the latest ota, so i downgraded and everything is working normally. There seem to be a couple of music problems with 3.29-although people aren't complaining that much.

I'll give it a try. I don't think it is a problem with the file itself, however, because I can play a song after everything is done downloading and it will work fine even if it was skipping before. It could be that between reading a 320kbps mp3, writing a new mp3 at 4g speeds, and deleting an old mp3 that the SD card is not fast enough?
I'll give it a try and get back to you.
So I did a couple things (stupidly at the same time).
First, I used the SD card from an old Evo (screen cracked, thank god for phone insurance) and reloaded everything on there. I think this is what actually fixed my problem. Read and write speeds should be the same as it is the exact same model of SD card, but I think it had the effect of defragmenting the card, enabling better reading and writing.
At the same time I tried Tickitata's idea and increased the cache size to unlimited. I streamed an album over WiFi and everything was fine (which it usually isn't). But then I noticed that I only had 2.6 GB of music on there and my cache limit had been 5 GB before, so I didn't think this was the problem and I changed it back. It still worked just as well afterward.
BTW Tickitata, were you having chronic stuttering problems that made the music almost unlistenable, or was it just a time to time thing?
In reply to sw99: I am using 3.3.0.1 not 3.29
I have someone on another forum that is buying a class 6 card to see if it resolves the problem for him. I'll let you know how it turns out.
Yeah, it was awful. Definitely to the point of being unlistenable.
Well, glad to hear you got it worked out.
Music occassionally stutters for me too. I use Mixzing and the 10 band EQ it comes with so I just assumed that the processor was getting bogged down with too many apps running while music was playing. Never really figured out the true cause.

Another CM10 question...AFT? I can't connect...

Okay, one other curious question...On CM10 7/29 build...is anyone getting Android File Transfer to work? Yes, I'm on a Mac, but it was working fine before, granted I had to call it a camera instead of MTP, but it worked just fine. Now that I got a 32GB SD, I'm wanting to transfer everything over, but now when I plug it in, I get nothing. Any ideas?
So, I've flashed all the roms on my SD card...CM9, CM10, Ultimatum, AOKP, now I'm on Paranoid Android(liking this one best because it's a mix of CM10 with more stuff working so far..) but anyway. I noticed on all of the JB-based roms, Android File Transfer no longer works. This wouldn't be an issue because I could flash Ultimatum, which is ICS-based, right? Still doesn't work. I've read around and some people say Samsung updated something that broke AFT for mac...but I'm just not sure. I just got a new 32GB SD, so I want to move the stuff from my 8GB to this one...but using wireless solutions will take hours on end...and I'm not even sure which one of these works the best. Any ideas?
I believe the file transfer on android does not like to work with cm10 on this phone and its not an issue that seems too high on the devs list because of the few amount of mac users. Really sucks but meh, honestly if i want to transfer stuff i boot up windows through bootcamp and do my thing
My suggestion is, flash a stock based rom and just move the majority of the stuff using mac and then for smaller/more periodic stuff after that you could just use a wireless transfer thing. Because for me, after my initial sync of all my music i usually only sync photos or a few songs at a time so wireless syncing wouldn't be too big of an issue.
Indeed, I found a workaround to use CyberDuck to transfer stuff...of course, my first big transfer is going to take hours, which sucks---I wish they would look at this issue...even if Mac users are the minority, that's a pretty big issue-Normally I wouldn't have issue with either dual boot or Parallels, but I'm broke at the moment so I'm running a G5 iMac. While it runs, you can imagine how slow it can get, since this is pre-aluminum models... I tried flashing a stock-based rom (Ultimatum) and it still didn't work. I've heard that a Samsung minor update might have broken it, but I didn't get any OTA updates. I'm just glad CyberDuck/SSHDroid let it work just like my jailbroken iPhone works with CyberDuck the same way, so I'm familiar with it. I guess I'll need to go back around the forums I was searching for answers on and post a tutorial on using CyberDuck with the S3.

6.0 Makes N7 Feel Like a New Device!

Am I alone on this thought? I was really thinking about selling this tablet a month ago and decided to wait for the update, because I knew how terrible Lollipop was/is. I really am glad I waited, this tablet feels like a brand new device! No lag, approximately 650MB being used on average!, battery life is amazing, WiFi connection doesn't drop anymore, so far I can't find a flaw! If I did, there are so many pros to this update it couldn't take away the happiness I feel about what is better!
What do you think? Am I alone on this thought?

I think it's great too. Much more polished. The only problem is that I can't access my microsd using user apps that don't require root.
Really? I thought that was one of the major changes to 6.0? Very strange... I don't use an external SD though, but still, strange nonetheless. I wonder how the Moto X Pure will do hearing this, considering that's a big selling factor for it.

Micro SD is accessible via system app. Once you insert your portable storage, go to Settings/Storage & USB and there you will see your portable storage drive. Click on it and you will be able to access your files. No problem watching movies stored on my micro SD. :good:
Unfortunately wifi option doesn't work properly and you can quickly drain the battery if you don't turn off wifi when you haven't access. Keep wifi on during sleep option is broken.

The catch is you can't access your files if you're not using a system app or a user app with root access. Since most multimedia apps don't actively ask root permission, they won't have rights to access the microsd folder created under "/mnt/media_rw". You can't change the permissions to the microsd folder either. Perhaps if you set up your microsd as "internal storage" (see adoptable storage feature) instead of "portable storage" all multimedia apps can access it (since these apps have permission for it, of course), but Android M didn't implement that feature yet, at least as far as Flo is concerned.
Luckly Chainfire's Stickmount app uses its root rights to mount the microsd inside the internal storage (under sdcard), where all apps have access.
I was quite shocked to find out that a feature like adoptable storage, which has been announced by the media as Google finally playing along fairly with external storage, seems to be actually quite the opposite.
in this light YES it feels like a "new" device ... coming directly from a backyard in china with cloned firmware not belonging to this hw ,-)
would be interesting what TO understands as "battery life is amazing" when standby lasts max 2days.
Having to en-/disable WiFi everytime I want to use my tab is anything but amazing.
To add another one to the list: access from PC via USB doesn't work either.
One has to enable developer settings to switch USB to MTM allthough it is allready selected, charge only seems to be default with no possibility to change for standard users.
This seems to be the most untested and buginfested "upgrade" I encountered in my Android history.
I doubt even M$ could do worse ...

i see the same problem. My wifi does not turn itself off. Has anyone found a solution for this battery drainer????
does this update bring any changes related to gsm dialing, gsm ussd dialing and sms receiving/sending?

I have that usb problem too thats some bull****.
Battery life is pretty damn good I got over seven hours screen on time over 3 days with not light usage (no games). I don't have any wifi problems but even a bad signal shouldn't drain it since Doze should shut it down so I'm not sure what would be draining your battery. I lose 1-2% overnight.
My biggest problem with 6.0 is Doze. Turns off everything for good standby time, works great for that but now I don't get lots of notifications like email or calendar when it's dozing and excluding them from battery "optimization" does not work. They gotta fix that ****.
looks like I'm not alone with WiFi battery drain.
Maybe it is related to the LTE version?
Today I lost 20% overnight ... on a freshly flashed system w/o any installed apps, not even google account.
Just WiFi credentials and set keep WiFi on to never ...
Good time to test the CM12.1 ....
Edit: somehow 6.0 fails to recognize my 16GB Lexar 3.0 USB-drive. It says it's defective and offers to format but fails with a runtime error. The same USB-drive works w/o problem on my lenovo.
Has anyone have issues downloading files using Chrome? I use CF Lumen, and Chrome prompted me to disable that, which I did. Tapping links for downloads has no effect; I tried multiple sites to be sure. Weird!
[EDIT] Delete please - I posted my question in the Lumen thread.
hmmm, mysterious.
yesterday I left it as is at my office and it lost only 5% in 16 hours ... allthough WiFi was allways on according to batt graph
Is this WiFi behavior normal for marshmallow? I don't think so... Any solution for this?
Unlocked bootloader and rooted
Hi,
at least yours doesn't lie to you. Mine pretends to have not been using wifi ... but if I shut it off, I can see the difference.
It is interesting that the periods where wifi is shown as off were situations where no wifi was available or couldn't connect.
Due to the graph and stats, wifi was on but didn't consume (allmost) any energy. But if I totally disable Wifi I can see the difference (battery life prediction: 15 days)!
If I sum up all consumption infos I get 258mAh used in about 9.5h. 258mAh are approx 5.9% of the battery (not 19%) and recalculated the predicted life should be approx. 16 times 9.5h ... so something is very flawed in this region.
Mine is exceptional, like 1-2% overnight battery usage. My only observation is when I set the tablet down and use it the touchscreen rarely registers a touch. When it is held in my hands and I use my thumbs it works fine.... It has a rubber tpu style case stretched over it, doesn't make a difference. It also has a tempered glass screen protector. Is there a way to turn up touch sensitivity? I know some Samsung builds actually had that option.

SMB/CIFS slow transfer rate

Hi,
Anyone noticed that the unrooted Note 7 transfer rate is very slow on SMB/CIFS (network sharing). Copying from a SMB server is around 200 kb/s. I usually get 3-5 mb/s on my Note 3 and Note 2 but both Note 3 and Note 2 are rooted.
A solution without rooting the phone is appreciated.

Usually the smb protocol is embedded in the application not on the OS (so , the app could use an old library)....just try another file manager like Total Commander or FX File Explorer. The protocol itself it is very susceptible to latency ... big latency = very slow speed. Because of this reason you could try another protocol to transfer files like ftp or ssh (scp).
I have the same exact problem. Doing benchmarks between my old Note 4 and my new Note 7 and I have extremely slow SMB/CIFS transfer speeds. I seem to be bottlenecked strictly to 10mbps or below, which is unusable for streaming any content from my home file server. It is not networking as far as I can tell since I can transfer at ten times the speed on my old Note 4 (100mbps+).
What's weird is that over FTP I can transfer much faster (not as fast as SMB/CIFS on my old Note 4, but about 40-50mbps). Another weird thing is when I first got the phone the slow CIFS/SMB transfer speeds wasn't an issue for the first week or so I had the phone but suddenly started to become a problem. I've done everything, trying to tweak Wi-Fi settings, restarting the phone, changing configuration on my home router. Nothing helps.
This is a weir, strange bug. I signed up on this forum just so I can reply to this thread, so in a way I'm glad I'm not alone in this, which means this is probably some software-related bug either in the OS or the phone that is artificially throttling SMB/CIFS transfer rates since I can never break 10mbps.
I also signed up to post my similar issues. I've been going crazy over the past few days trying to figure out why my transfer speeds from my NAS were horrible while my old Note 3 was fine. Both my original Note 7, which was recalled, and this one have this issue. I get roughly 200-500 kbps down while my Note 3 is getting MBs higher. However, if I connect to it as an FTP through ES File Explorer (app I've used on both phones, even tried other ones to no success), I'm getting the speeds I should be getting. This is truly odd... I thought it was my router but it turns out to be Note 7 related. I've also noticed that if I use the app for my NAS (Synology) to connect to it, it uses an HTTP protocol, so I'm also getting the speed I need there too.
Hopefully there's an update in the future that address this. I don't mind using FTP but it's unfortunate that I spent so much diagnosing hardware and software to find out it's Note 7 related. :/
Unless of course I'm just missing something...

(Problem) Very slow speed transfers, software fault or hardware fault?

Hi, my Mi A2 Lite is facing issues regarding file transfer over USB... it's transfer is far too slow, Windows says it will take about a day only to copy all the files from my phone! I'm using a SD Card as internal storage (is adoptable storage) but the card itself is pretty fast since is A1 class (I have lots of apps in it and all of them works like if they were in internal memory).
Even when I first copied data to it's internal memory it took a lot of time to finish.
I have latest update (Android Pie 10.0.4.0), but with other versions the problem was there as well, my SD Card is in a good state since all apps on in opens without problems and pretty fast, but transfer is really slow, here is a pic copying music:
It says "23 horas" which is 23 hours, it's impossible to use my device like that, I still have 2 month warranty though, so I would like to know if someone has the same issues like me or not, since I can ask the seller for a new unit.
Thank you!

I also experience that issue as well, not only with this phone, but also other Android phones with micro USB port too (and with USB 2.0 interface).
I think it's the MTP thing (which it sucks b***s by nature for transferring files in my opinion).
Trying another PC's USB ports and never put phone to sleep while transferring files via MTP will reduce this problem for me, sometimes.
Since I'm not using my Micro SD as internal storage, what I did is just eject my Micro SD and use a faster card reader for transferring files.
I see, it's really strange indeed, because I had a phone (LG F60) which run KitKat and the file transfer had normal speeds, it was MTP also with microUSB 2.0, I guess it's a software bug on Android then, hope Google fixes it.
I face also this problem but only when I'm transfering lots of small files, not with few but big ones like movies. I started using the ftp server option included in Mi Drop app and it's better but not nearly as fast as USB2.0 native speeds.
@AndresX it's a well-known eMMC storage bug. A2 has one, A2 Lite has one. Daisy has eMMC 5.1 which, comparing to UFS 2.1 or UFS 2.0, is the slowest one. More to that, it's getting worse over time. I attached benchmark from Androbench, didn't change the settings, see how yours compare.

A bug in eMMC? that means it's hardware fault??, eMMC 5.1 speed is not a problem for me (Surely my old LG F60 had a NAND that was like that or even worse, but it's transfer file time was fine).
I will try that benchmark, but it would be good to know if it's a hardware problem since my phone it's still under warranty. Thank you!
No, it means it's a software fault, hence the "bug", you can find it on official Android Issue Tracker, it's still unresolved and it's on the dev side to fix this.
On the other hand you might want to check if your USB port isn't faulty which is under warranty but the port might get mutilated from careless plugging in to charge which would be visible. It's a common thing for e.g. USB3 speed to become USB2 speed when ports aren't handled properly.
Bit as you stated it happens between internal memory and SD card so I'd say it's software.

Oh all right then, my USB is fine I think, phone charges without problems and the connector doesn't feel loose or anything, I will attach my screenshot of the bench, if it's so bad then I will use the screenshot to send it to Xiaomi via te feedback app.
Edit: I already enabled all data collection related to Mi Services and Google to see if that helps a bit to report (I don't care about my data, I don't have any thing that is sensitive)
LOL. Your sequential / random values are a lot faster than mine and I don't complain and didn't even noticed that transfers may be slow XD. I guess it's a point of view and expectations then.
Sent from my Mi A2 Lite using Tapatalk
It's strange because the phone feels pretty fast... Real responsive... But I don't understand why the MTP transfer is so freaky slow and corrupt (because I did notice that it sends the data it wants, sometimes it just cancels by no reason...)
I don't understand this, guess I will take a screenshot of Windows again and show that on my feedback report...
Just noticed you downgraded and rooted. After many hesitations I decided to update to Pie just because of Oreo's being laggy after some time of usage. I know it's subjective but Pie feels faster and it has better RAM management which results in for e.g. faster unlocking and switching between the apps. On Oreo I had to reboot and clean recent apps every now and then which I normally don't do and it bugged me so much I move to Pie.

Yep, I downgraded to Oreo due to battery life, but external storage was imposible to use and I think (but not quite sure since I don't remember well) that the MTP bug was there too, so I ended up using Pie.
Pie isn't horrible but needs to fix a lot of things like the SD Card Missing issue, Battery Issue, MTP Issue, etc...
If I want to update the security patch the only thing I need to do is flash original boot.img and unroot right?
That's what I understand from the Magisk root thread.
