So this is the future thread of DATA2EXT.
Basically this is a hack to mount part of /data onto the SDcard, improving I/O thoroughput, as data will be written to internal NAND and SDCard. (Theoretically)
I've currently gotten really close to a functional DATA2EXT.
About to flash the next test, and I think I got it this time.
Progress will be posted here.
v1: Failed. Not that easy.
v2: OOOHHH. Still failed.
v3: Mhmm. THAT should do it.
v4: Heyyy! Found an error! *fixes. Trying now =] Failed as well.
v5: Failed failed.
lots more fails.
v17 Trying new idea now!
Bugs go herreeeeeeeeeeeeee
Maybe some random stuff here xD
Thanks man I'm excited about this thanks for looking into it.

EDIT: Haha... I realize that this quote has nothing to do with cyanogen's warning xD Oh well
Yup yup. I respect cyanogen, but from what I've read, it seems his main issues are:
1. Doesn't actually help anything.
2. Doesn't get wiped, so errors between ROMs will occur.
However, theoretically, it SHOULD help. Read / write is now spread across NAND and SD, so should increase I/O. But again, real-world difference has yet to be looked at.
Wiping it IS possible. One could delete the partition, and the recreate it. Wipe. What cyanogen seems to mean is that it's not baked into clockworkmod. It means that a separate zip will have to be included for those who want to wipe.
But again, I've yet to get it actually functional. Once it's functional, the performance vs risk can be weighed.
On another note, I've seen talk about DATA2InternalStorage. It certainly makes sense, we've a whole 6GB to play around with, and it should be really fast. However, the added r/w that occurs with DATA2X should drastically reduce life. And since we can't change it out... not a good idea.
The SD card can be changed out very very easily, so a shorter life shouldn't matter too much. And I'm not sure of the logistics, but if internal storage is on the same NAND as /data, then moving writes over to there really won't improve anything.
Anyways, I'm testing v4 now after my phone charges a little more. *crosses fingers.
.
What partition layout is needed for this? Maybe you've already seen it, but I've been following THIS, also.
hopefully this helps with real life performance too. When I compare the inc to the crazy fast new devices out there, I feel a bit jealous. If I see some increased speed/smoothness, it will certainly be worth it for me. Also, will it be possible to get this in a flashable zip format? 1 for AOSP Roms, 1 for Desire Z/HD/MT4G Roms, 1 for old sense based roms or am I smoking the wrong pipe in thinking this way?

I've been tweaking the script to work for the DInc. I had to change the place where it mounts stuff, and I've finally got bootup. However, still a billion force closes. Digging into this...
This is all very interesting and I thank you for taking the time to try and get it to work. I just hope in the end it is worth the effort
I agree! Can't wait to test for you! And again thanks for putting your personal time toward improving our devices!!!
How did it go? Any luck getting it stabilized?

=[. Noope. Failed failed failed. haha, but at least I'm making some progress. About to try again now, I'm getting closer each time xP
After so many failed attempts, I am forced to give up.
It's too much work for too little gain.
The whole point of DATA2EXT is twofold: Increase /data space for apps, and increase I/O.
The Desire (what this was originally designed for) has a 150mb /data partition. That's hilariously small.
The Inc has a ~700 mb /data partition.
Hilariously huge.
So, the /data space point is moot.
As for the I/O speeds, there are no real-world benefits. Yes, I/O will increase dramatically in Quadrant, but that's it. Quadrant writes a pretty large amount of files to read I/O, so difference in I/O speed helps.
But that's not the case with apps. Apps store their data in /data/data. The whole of which is usually about 170kb. Yes, Kb. Not even an MB. If I write at 1mb/sec, I'm done in about 0.1 seconds. The I/O will increase throughput to ~2.6mb/sec. I'm done in about 0.065 seconds. That's a 0.035 second difference.
Again, that's if EVERY SINGLE app was writing at once. 0.035 seconds. Negligible.
Haha, I do realize I am making such a strong case against it because I couldn't get it to work xD
So, in the end, Cyanogen was right xP It's just a benchmark hack. Real world performance doesn't depend on I/O.
got it. Now it makes more sense. thanks
finally come to the same conclusion?
i worked on it for a bit, did a bit of research, got it to boot.
after researching a bit more-and being stuck at the FCs where you were-i gave up. cost/benefit ratio just wasnt gootd enough

I've had pretty much every nexus device, but last year I decided to get myself an Iphone 6, but I really missed android, so I'm about to get the nexus 6 but some issues are keeping me from doing it, I've read quite a few reviews and I'm concerned about the following issues:
1. Why is the camera so slow to take pictures? You think it could improve in the future? That's probably the thing I like the most about the iphone 6, how good the pictures come and how the camera is blazing fast
2. Is it true that the device is slower than the nexus 5? Have updates improved this situation? My nexus 5 already stuttered with Lollipop, Ive read quite a few reports about the phone slowing down and lagging for no apparent reason (except for maybe the quadHD killing the cpu/gpu)
3. How true are the reports of screen burn in?
4. How do non google apps and icons look? I imagine pretty bad since facebook or instagram's icons haven't even been updated to take advantage of a 1080p screen
5. Is it true that the device has slow storage a step down from the nexus reading and writing speeds?
Thanks for your help

Where are you coming up with these questions? The only icon I've seen that actually looks bad, is the one for my bank... and it looks bad on ANY screen. Screen resolution is not so tightly tied to "icons" -- bigger screen = more icons. Also, Nexus 5 was already a 1080p display. I also hardly consider this question to be meaningful. Who really cares what icons look like? The objective is to maximize USEFULNESS.

No. Flash storage is blazingly fast on this device, HOWEVER, the "default configuration" enables data partition encryption by force, which reduces the EFFECTIVE flash performance to nexus 5 level (which is still very good). Simple adjustment to a text file on the boot partition allows this to be disabled. It is also probable/possible that Google will be enabling hardware crypto on the next update.

I'm in agreement with @doitright. I can say nothing but good about this device. I do not have any of those issues nor know of any that do. As with any device though there are always some bad ones that an unlucky few receive. It does not make all of them bad just those. My phone is a beast. It outperforms the N5 by miles. Screen looks amazing. Icons to me look great I haven't come across a bad looking icon except that of my bank.... I guess banks hire poor developers idk. Storage is incredibly fast. Camera is fantastic. Fastest signal acquisition I've seen on any phone including GPS.
Eh. Entirely up to you what you want to do. I don't trust any reviews. I rather go with my own opinions/feelings on anything. You should too.

I'm awaiting this Thursday to grab one on VZ, coming from a Galaxy Nexus, anything I could get now would be a major update hardware wise, however the only exception I take is the last part of this, not trying so start anything, your other parts are spot on.
The current speculation is that 5.1 may go backwards on forcing software encryption, but nothing is confirmed there, see last paragraph:
http://www.slashgear.com/android-5-1-in-march-heres-what-may-be-coming-18369666/
If the Nexus 6 had the HW encryption on it, and I cant confirm it does, we're left with these options:
1 - they do enable it, which begs why it wasn't in the first place. Current rumor is that the qualcomm drivers for that engine are not open source, therefore it is a no no on android:
http://androidheadlines.com/2014/11...ency-likely-due-missing-qualcomm-drivers.html
2 - they tweak the software encryption, which if you check the threads, opinions really vary here. if you need to irk the absolute most out if it for read write, then undo it. But plenty of others have chimed in saying it wasn't that big an increase, i believe it to be what you may be using on the device that makes the difference, more intensive apps may cause the SW process to bog down, but in all, it is still fast.
3 - they disable it by default, which I wonder how that would be accomplished in an OTA, it would need to wipe the device I'm sure, but ...
4 - Lastly, if in fact they cant use the engine, or it wasn't included (doubtful, it has qualcomm in it) then you cant enable it by an OTA, end of that story.
Personally, if I grab the N6 this week, I plan on unlocking/rooting/removing VZ oem partition, but for the moment leaving encryption on, because 5.1 may drop in March, and then see how things are at that juncture.
It would be great if they could enable HW encryption, because we get that security and maintain read write offloaded from the CPU.
Lastly, I plan on trying to enjoy the thing, playing with it for at least an hour in store before taking it (you never know) because as most of us here are OC hehe, reading all the threads of issues before buying it is kinda a downer. I know I'm going to love it, having waited three years to update myself.

You can't do anything to increase the fuzzyness of an image, unless you actually stretch it larger. I.e., if it takes the same physical space on the screen, then increasing the DPI on the screen won't cause it to become more fuzzy -- it just won't increase in SHARPNESS with the display. Google has specifications regarding the dimensions of the icons, and these specifications have always included a "much larger" image than what will actually display on the screen. The icons actually get scaled down to fit. So really, don't worry about it. If you find an application with a ugly/fuzzy icon, complain to the application vendor, because they're the ones who made an ugly icon, not the platform.
I just can't stress enough, that this is a silly point to use to avoid a device.

I *absolutely promise you* that they WILL NOT eliminate the encryption requirement. Those "android one" devices are... really really cheap. It is likely that they don't force encryption simply because they are not up to the task.

I CAN confirm that it does. There is no question at all. It is part of all snapdragon SoC's since about S4.
1 - they do enable it, which begs why it wasn't in the first place. Current rumor is that the qualcomm drivers for that engine are not open source, therefore it is a no no on android:

There are two sides to the use of encryption hardware with qualcomm SoC's; the first is the "blobs", and the second is the integration with Android and the Linux kernel. Specifically, qualcomm's hardware crypto requires changes both to the kernel (which is under GPL), as well as VOLD (which is under APL).
Obviously, to include the kernel part, that kernel part MUST be provided as source. There is absolutely no option here.
VOLD is the part of Android responsible for mounting and managing disks. It is under the Apache license, which means that technically speaking, it can be distributed without including source, HOWEVER, this is a Nexus from Google, which means that they really can't ship a blob in place of VOLD. It has to be possible to build VOLD from AOSP.
So here is what was going on; at the time that Nexus 6 first shipped, Qualcomm HAD NOT made the source for Kernel or Vold available on CAF. That made it *impossible* for Google to include, since they would have to provide kernel code on request, and require that AOSP VOLD actually build and work.
QUALCOMM HAS SINCE MADE THE SOURCE AVAILABLE!!!!
And, in fact, there are a number of devices for which CM actually builds and includes hwcrypto *right now*.
2 - they tweak the software encryption, which if you check the threads, opinions really vary here. if you need to irk the absolute most out if it for read write, then undo it.

This isn't even a half solution, because even though it may seem to improve storage performance to an acceptable level, it has to nail the CPU while doing so.

You could disable crypto now, and let it encrypt when the update rolls around. Disabling forced-crypto does not prevent you from using crypto now or later.

Yep, I'm totally with you on that. My last phone was a samsuck.... NEVER again. I spent WAY too many hundreds of hours on kernel and device tree maintenance to get and keep that thing working adequately on CM... then Omnirom (omni is waaaaaay nicer than CM). After a year of ownership of that thing, got the wife a Hammerhead (nexus 5), and its been just so easy to maintain. Literally all I ever did with her phone was add root, busybox, and xposed (to kill a couple of the google services wakelocks). This time around, I wanted the thing to just freaking work already!!!! Only downside is that its a bit *larger* than I would have liked.

I don't think that you should buy from verizon, even if/when they sell it directly. It will likely be crippled and branded, at least to some extent. Buy it from tmobile or google play store, and all you need to do is throw your verizon sim card into it. I think I heard that sprint also does not molest it. Oh, it could also be purchased directly from motorola.
Just whatever you do, do NOT buy it from ATT. They DO molest and cripple it.

To gain RW performance NOW... DUH.
I'll be getting it from VZ, because I just don't have the spare $$$ to buy direct and place it on VZ.
ATT taught us that VZ will have to toss its bloat on the oem partition just like anyone else, so ... as far as branding, I think that may rub off like ATT's, but if not I plan on putting in a case anyway.
Now we have to wait another two weeks if the newest rumor is true ...
To those that updated to 5.1 via OTA, what's the disk speed with encryption turned on? Is it much improved over 5.0? Does it take advantage of Qualcomm's hardware?
I came here to learn the same. I have the modified boot to disable encryption, but if the new HW-based encryption is much faster, I'll happily switch back
Yes very interested in this. I am holding off on the ota since I want to keep it unencrypted and I can find out how to move to 5.1 with staying decrypted

It looks like there was a performance improvement.
Won't HW encryption still be slower than NO encryption?
Do we know for sure that HW encryption is enabled in 5.1?
Looking at some of the commit messages, I first thought that it *might* be but the more I looked at the code, the more it looked like they did a lot of prep work but actually kept it disabled (i.e. we're still software-only).
I could be wrong, though...

Really hard to judge. But either way, it's clearly improved. Less fast than NO encryption, much faster than before. Sounds like that's PROBABLY due to hardware.
Either way, I do have to say that so far my phone's performing better. Not merely subjectively. A game I play (Spider-Man Unlimited) was impossibly laggy before. It was known for having lag issues, but on my Nexus 5 and 6, post-Lollipop, it was nearly unplayable. In the short time I've been running 5.1, it's been a dramatic improvement. So even if encryption does cause a small hit, other improvements have more than made up for it.

For those that do know how (I don't), can we find out if hardware is being utilized? Perhaps through source code or logs?
Also, is encryption still forced? That is, is there any option in settings to disable encryption if encrypted, without using a modified kernel?

What what spider man unlimited is now playable? Biggest news ever!! I'm not joking either. I've had to constantly play on my moto x instead. [emoji106] [emoji106] [emoji106]
If they moved it to hardware encryption, I may re-enable it, but would rather wait to find out...figure it is saving me some battery by having encryption disabled still.
They do mention it being enabled or added here:
http://www.androidauthority.com/android-5-1-changelog-593573/
Is there anyway to confirm that it was indeed flipped on in the code?
Hi, I'm new here, but I've been around for awhile, trying to find someone who has been going through the same stuff as me, and I finally have. My dilemma is this. I just got my nexus 2 days ago, upgrading from the n5. After installing 5.1, rebooting and restoring my apps I began to notice some lag. Like touchwiz type lag I had on my old note 2. And for the life of me I can't find any info on wtf is going wrong. It's the little things that I definitely expect a brand new phone to not do. For instance, when I swipe away running apps, they hang and freeze on the side of the screen. Play music routinely freezes when I try to play an album. Whenever I go from chrome to messenger, or close the app drawer, it lags. To the point that I don't even want to let people check my phone out. It is noticeable. I went back to T-Mobile and they said their diagnostic couldn't find anything, and maybe I was just too critical, but I'm not happy with this performance. I'm not rooted, just running apex launcher, animations turned down, no 3rd party apps, and it's not right. My question is, what do I do? I've got a week left on my grace period, does this sound like a faulty phone? Please help. I honestly don't want a different phone, just a "blazing fast, lag free nexus" as so many of you declare you have. I'm probably gonna have to shell out 50 more dollars for a restocking fee, and if I do and find that this is just the performance I can expect from the nexus I'm gonna be screwed. I hope you guys can point me in e right direction, because it seems like for most everyone 5.1 addressed all the encryption lag and stuff. Yet my fresh out the box device is as bad as my n5 was. Thanks in advance.
I also notice the lag when closing running apps and also in Play Music but not when closing the app drawer. My nexus 6 also gets pretty warm.
I think its an issue with android 5.1 and will be fixed in the next update hopefully.

I can't say I've noticed any lag or freezing, but there again I've been running a custom rom/kernel since day one. I suppose you could scale down animations to help any lag.
My phone only gets hot when turbo charging, as does every turbo charge phone.
Yeah the heat issue is not a big worry for me, but I'm just trying to figure out if my expectations were inflated or if there is something wrong with my device. As it stands now, I could not in good conscience pay 700 bucks for this device. I am a mailman, so I use my phone all day for music, directions, calls etc. And I'm out there moving quickly, I can't spend the time standing around waiting for maps to load, or play music to load up the beast mode playlist And what not. With my n5, OK Google and wired skullcandys I had full command until lollipop screwed it up. When you guys say you see No lag, do you seriously mean when you swipe away apps they just fly off the screen full speed and liquid smooth? I wish
Flash OptiPop, the fastest rom for both N5 and N6

try factory resetting from the stock recovery.
I have had my Nexus 6 from Verizon for a month. I am stock with Nova launcher. No lag anywhere at all... I use play music all day at work and I swipe the apps to close the programs a few times a day. Never have I seen them stick to the side for a moment. I have have my phone seem to lockup a few times but a reset always makes everything okay again.

Kill the 3rd party launcher, that can definitely be a source of problems like you are describing.
Second, root, kill the encryption, format data partition (to actually remove the crypto), restart. The encryption in 5.1 is *STILL* swcrypto, and will definitely cause slowdowns, increases memory consumption, and is just downright miserable.
you got to try things out. different software is not all the same.
Do any of your apps have accessbility access? I have been experiencing similar symptoms to yours, there's a video showing what it does to animations in the thread I made asking if anyone else experiences this: http://forum.xda-developers.com/nexus-6/help/ui-stuttering-caused-accessibility-t3088343
Try turning off all accessibility access permissions and see if it goes away.

Man I wish it was as simple as you make it seem. To me that sounded like if I said I want an 11 second car, and you're like, well just swap in an rb, port and polish, bigger turbo's, etc. Haha its not that easy I think. I've always wanted to try root, but I was afraid to brick it up. If I've decided to pay the restocking fee anyway to get a new nexus, would it be unwise to try rooting now?
So I'm still having this problem, and unfortunately I have been unable to find any explanation for why this micro stutter exists. I think I have to return this phone but tomorrow might or forever hold my peace. I'D really appreciate any insight available as to why a brand new flagship caliber nexus would have micro stutter that I can't fix.
Thanks guys
.just bummed cause there is no other worthy phone at the right size besides the nexus. But I can't pay for a glitchy device.
Sad but hopefully an update will fix it soon

If you havent traded it in yet... did you try the factory reset? Definitely remove apex, try the phone with stock launcher, then with nova. If that doesnt work for you, I would root (make sure you study and learn) and install a custom ROM. I'm currently running AISP, its the best ROM Ive ran so far on my nexus 6 Good Luck bud.
As soon as I got mine, I turned off encryption and minimized animations and had no problems. Now I'm running a custom rom, and still no problems. Fast as #&%@.
encryption is not the issue

I wanted to thank all you guys that posted, I appreciate it. So I went ahead and restarted in safe mode and realized the problem lay with one of my apps, or running alot of zooper widgets and not factoring that into account when judging the speed of animations. Anyhow, I havent identified a particular app that was causing the problem, but it has gotten better now that Ive cooled it with zooper. Still love this phone, glad I didnt trade it in for a smaller s6 or old g3, next step, learning what im supposed to do once Ive rooted this phone.

Flash a custom rom
Could you tell me how you found it there was something wrong with an app?
And also if you have figured out could you tell me which app it was ?

My AT&T Galaxy S5 (Lollipop) says there is an "update available, connect to wifi". Its 895MB so I'm assuming its MM.
Any problems going to MM from Lollipop ? How can I find if all my apps are compatible with MM ?
I just turned on wifi and it started to download. I turned off wifi for now so it stopped.
Have they addressed most of the bugs with MM ?
These may be dumb questions, but I hate to change things when they are going good as they are...

here is ifo on update log : https://www.att.com/devicehowto/tut...tep_KB424848?make=Samsung&model=GalaxyS5G900A
After seeing the update availability on Sunday night (8/28), my wife and I downloaded and updated both of our S5s with the 895mb file from AT&T. Downloads took a little over an hour and updates about 20 minutes. No obvious problems and both phones seem as or more stable than with 5.1.1. Battery usage seems dramatically improved as well. We've each run through most of our favorite apps and nothing seems amiss.
Getting reading to change our SD cards to adoptable (internal storage) tonight. Hopefully that goes well.

Hi, its been a few days since you upgraded to MM. Any problems come up ?

No problems and although some people are saying battery life is unchanged from 5.1.1, that is definitely not the experience I'm having. My use is fairly consistent from day-to-day and I find i have about 20% more battery life left at the end of the day. However, I do no gaming of any kind and video is generally limited to youtube technical stuff and an occasional movie trailer.
Again, the experience is certainly not less than before the upgrade.
One disappointment however. Samsung does not support using the SD as an internal device, even though the OS does.
I'm now looking into rooting the device, but it seems a little early since MM was just released.

Thanks for the update.
So the phone does not see the SD card anymore with MM ?
I thought the AT&T version couldn't be rooted because the bootloader is locked..

I can see the SD card just like before, but one of the features of MM is to allow the SD card to be treated as internal storage so that apps can be loaded there. Unfortunately, Samsung has somehow caused this to be disabled on their devices (even on the S7 with MM). Rooting would be the only way past that as far as I know.
I believe there are instructions here on xda to root an AT&T S5, but only with KitKat at this point.

I was reading in another thread that Mobile Hot Spot is now disabled. Since your on AT&T, can you check on your phone to see if Mobile Hot Spot still works. Thx

Since I use a MiFi for connectivity, I've never used the Mobile Hot Spot and don't have it on my plan.
I did check my phone for availability, however, and it's right there in Network settings. If I attempt to turn it on it just tells me I need to go to AT&T to get a plan. If you have a plan it should work.

I'm on a mobile share plan which says it includes Mobile Hotspot (which I have been using without a problem). Just wanted to make sure MM didn't screw it up. Thanks for checking. I guess I'll update it this weekend and see how everything goes
