[Q] [KERNEL] Devil 1.9.5 Swap - General Questions and Answers

Hello!
I'm using an i9000 with CM10 and Devil 1.9.5.
I'd like to say I'm completely BLOWN AWAY by how good this kernel works. I've tweaked it a little according to info I researched around and so far it performs flawlessly (three days into it).
The thing is, my phone has just gotten so good that I'm not sure if there's any significant improvement to be achieved over this. I've purchased a 16gb Class10 micro SD, and am looking into activating the swap function in Devil (currently using 50mb of zRam instead).
1) Is it worth (performance wise) doing? What kind of changes should I expect and to which kind of applications/usage? Is the battery consumption going to change?
2) Is it worth sacrificing the longevity of a micro SD card for the added performance? If so, how long should I expect to be able to use it before it fries from the constant R/W?
Thanks a lot, BIG UPS to DerTeufel1980 for the insane level of quality he's been able to achieve.

Is anybody using SD card swap in any form on their phones? I've already found out that there's no change to battery life, but all the other questions are still unanswered...

Hanging in there - Great Hardware, painfully bad software

The most amazing thing about the Samsung i510 is that even with the Rezound, Bionic, Nexus, and Razr out or on the horizon it’s hardware is still pretty damn good. Dollar for dollar, it is arguably the best screen out there and the CPU is quite adequate. The RAM is a little low, but again it’s adequate. I even really like the physical buttons and the Battery is ample (from a physical perspective).
The software! It’s all the software. I don’t think I will get a Nexus when it first comes out because I’m sure 15 days after I have a Nexus in hand Samsung will finally deliver 2.3.6 OTA with source. There’s no reason that this phone can’t become a great performer, sip slowly at battery all day long, and get CM9 in 2012 - but the patience VZW and Samsung asks of us is excruciating!
I agree I usually trade phones as soon as possible and my wife said no or what are you going to get next. I said actually Im happy with this phone atleast for awhile. Not like I was before and trading or buying as soon as I can. In between now and next year I see a possible dramatic advance at even what is coming out this year.
I totally agree. But I am not looking to upgrade to GB. It sucked on my D2 and I will not download it on the Charge. I just keep upgrading the Modem software on the Charge. That makes a big difference for me with each new software update.

GB is better than Froyo in every way on this phone. I had constant lockups and random reboots under Froyo, but everything is smooth as silk under GB. You can't compare two completely different pieces of hardware and two different software builds to each other in terms of performance. I tried at one point to go back to EE4 and I was back EP1 within two days, because by that point, EE4 was just painful to use.
Currently on EP1W and I think its great. I find that EP4P radios to seriously rock. I will upgrade to EP4P base soon depending on when we get the OTA update.
My phone is super-stable overclocked to 1.252 GHz. Seldom radio issues, good voice quality. I freeze all kinds of stuff with Titanium Backup. I generally have no issue with RAM, but don't play games... All my apps (150 user installed apps) are stored on internal memory for speed. I may upgrade the rather slow class 2 micro-SD card to a class 10 card though.
If you take some care of your setup, you will be rewarded with a great phone.
Current Setup:
Humble 4.22 EP1W
Imoseyon Kernel 3.1
Modem: EP4P
V6 Supercharger
3G Turbocharger
I/O Scheduler Changer (running noop)
Tegrak Overclock
Changed Vocoder to EVRC-B
Voodoo Control Plus
Voodoo Screen Tuner
Oh, by the way, am I the only one not not highly stoked about the Galaxy Nexus? My primary complaints are no Wolfson DAC, pentile display, curved glass, and no micro-SD slot. Also, it has the same GPU as the Charge, albeit clocked higher. I personally will wait for the Galaxy S 3 for HD SAMOLED+, but who knows what the audio hub will be (hoping its the Wolfson.)
I used to think gb sucked after loading the earlier builds. Really buggy and laggy.
So I stuck with ee4 for the longest time.
After trying out the latest ep4 build, I completely changed my mind. Superior to froyo in every way.

I was right there where you're at...then I went from stock to Humble 5.0...phone is now pretty frickin nice in my opinion
Latest GB release is smooth
I agree with all the posters here. I finally flashed 2.3.6 and what a difference it made. Lag is non-existent for me, battery life is much better, data drops have practically disappeared and phone is snappy. GPS still is slow and not very accurate. Download GPS Fix from the market and run it before you use GPS....problem mostly solved.
Overall, made this phone run the way it should have from day 1.
Those of you waiting for the release, don't. Follow the instructions and flash the new release. It is very easy and you will be glad you did !

Humble 4.22 and 5.0 are both based on GB. You can't tell me you don't experience the buzzing noise issue, can you? THAT to me is a show stopper. I don't care how fast the datarate is but this phone still needs to make calls reliably.
Tried every GB leak variants out there and none of them has that issue solved.
Have gone back to debloated EE4 with Imoseyon's latest kernel and the latest EP4P modem installed. Been very happy with it; man, it's fast, no lag, super stable, no issue with swypes 3.0's cursor jumping around like crazy when you're posting your post on forums (surely you all have gone nuts over that problem).

I am not on Humble, but I'm running a coredroid themed version of the 2.3.6 TBH leak with imoseyon 4.0 so it's basically the same thing as Humble.
To be totally fair, I do mostly texting & don't make a ton of phone calls but I have never once had a problem on a call. I talked to my boss yesterday for 45 minutes on a call & it worked just fine.
On the occasional calls I do get or make, this phone (for me anyway) is loud & clear & much better then any previous phone I have owned (& I have had a TON of phones)

Tons of posters on this forums have the same issue.
But I hope you're right. And I intend to prove your theory, hopefully soon. As soon as the GB OTA is out, I'll be demanding a replacement if the problem persists. With a Nexus perhaps, if I'm lucky.

The noise just started happening on my wifes phone and she is bugging me about it.I dont really have the problem so was thinking of just re flashing radio files and see what happens.

I think I have to agree on all counts. I was super excited about the Galaxy Nexus coming to VZ & had a standing order in with our VZ corporate rep telling her I will buy it as soon as you can get me one.
I am having serious second thoughts however. I am so incredibly happy with my latest Charge setup (2.3.6 TBH leak W/imoseyon 4.0, LPP Plus, Fuju tweaks, camera button mod, coredroid theme etc.etc.etc.) that I am beginning to realize that with the Galaxy other than the dual processor it would actually be a downgrade for me in a number of ways.

I have a good news for some http://www.droid-life.com/2011/11/2...rge-gingerbread-update-rolls-out-november-29/
Official GB release date has been announced.

[Q]External partition

I am planning on making a 1GB external partition.
Now the question is: will it affect SD life? It is used very, very much, 100% of times...
Does it also affect battery life?
Thank you.

I don't know about SD life, but it's unlikely it will affect it.
As for battery life, I haven't noticed any difference

Well, I heard journalism in ext4 could affect SD life, but without it is there any danger?
Sent from my LG-P500
Don't think so. I've been using an ext partition since two years and my SD card is still perfect. In fact, it's better than it would normally be, since I don't remove it
SD cards have a limited lifetime, like SSDs have too. So every read and write cycle shortens their lifetime a bit. That's why it is said, that ext4 effects the lifetime of a SD card. I don't think this matters a lot though.
Swap is different there, I think this'll decrease your SDs lifetime a lot, since there are uncountable r/w-cycles.

[Q] How noticeable is the speed increase with data2sd?

Let's be honest here: Even with the latest rom, CROMI, etc, the tablet still suffers from abysmal I/O performance, with translates to laggy UI, long homescreen redrawing times, etc. Now, I'm seriously considering getting a $100+ 64GB UHS-1 95mb/s capable microSD card to use with data2sd. But how much does this actually help? I know any experience is likely to be highly subjective, so, along with opinions, would anyone care to contribute some video comparisons?

Frankly, I find that browsing has mostly been solved with browser2ram, and movies off internal storage always worked for me. My main remaining annoyance is the homescreen redrawing - when rotating on homescreen, waking up from sleep or switching back to homescreen after gaming, it takes several seconds for app icons to appear and even longer for the widgets to fully load, during with the UI stutters horribly.
Sounds like a launcher problem. Which one are you using and have you tried others?
I'm using the stock launcher. I've tried nova and apex, and the problem is less pronounced but still there.

I'm runing data2sd with 16gb UHS-1 95mb/s, cleanrom 3.2.2, _that_stock Kernel with ROW scheduler, journaling and fsync disabled. My tablet is super smooth, no stutter, home icons/widget redraw etc..However, if you do a clean install of cleanrom with stock kernel, you should NOT have that kind of experience you described. I suggest you do a full wipe then perform a clean install with _that kernel, and don't install too much "junks" on there, only install the apps you really needed. When I have time, I will try to make a video of data2sd on 95mb/s card.

Power Users: Post Your Optimal Setup!

This thread is intended to have power users post their best configurations so as to guide the rookies in optimizing their MXPs once they get unlocked and rooted. It's also intended to compare the best setups for battery, performance, gaming, multitasking, etc.
My main interest is in battery life, although lately I've been on the XDA Labs app like crazy and it's hurting my drain.
Constructive criticism welcome on how to improve the below records!
ROM: Stock MM Canadian
Kernel: Ultra Kernel R3
Governor: Smartmax
Frequencies: 200 big, 800 little
Xposed Framework modules: Force Fast Scroll, Lucky Patcher, GravityBox (duh!), Use USB For Marshmallow, Xposed GEL Settings
Best SOT: 8 hours
Best Drain (100% to 0%): 120 hours
Other miscellaneous tweaks: Shake Flashlight as a system app instead of double-chop (works great, just don't let go)
Launcher: Still figuring that out...but Nova and DarkLauncher are worthy contenders right at the moment
Voice Assist/Google Now on long-press Home: Disabled thanks to @pijes. Settings > Apps > Gear icon > Default Apps > Voice and Assist > None
Post below, power users! What's your best setup so far?
Bro, I would like you use Greenify and DS Battery saver
As you have xposed framework installed you can use boost mode in greenify and also
DS Battery saver also has a module so activate them and then choose slumberer and phew see your battery stats
Coming to launcher, right now Arrow launcher is good and smooth and I prefer that
Thank you!

Cool man thanks. I'll try the Greenify and DS you recommend. I've seen Greenify a lot around XDA. I'm excited to try it.
Tesla rom(seems faster/smoother then stock/anyother rom) plus Squid kernel. Governor is set to Lionfish and I/O scheduler is set to Row with 512kb readahead. Minimum frequency for the Big cluster is 800mhz and 499mhz for the little cluster. NFC and location disabled. Best battery life I ever got was with stock with the same kernel/settings configuration, had 9 hrs SOT and nearly 24 hrs overall.

I need to learn more about I/O scheduling. I've changed to Row and 512 as you recommend but where will I see the difference? When I connect to my PC? When apps access internal storage?
I've changed my governor back to lionfish. Smartmax wasn't doing it for me. 200 big 800 little. I'll look into that Tesla ROM too.
I was hoping this thread was gonna be more popular. I hope some people have gotten use out of it so far! Grow little thread, grow!
It would be awesome to see more growth in this thread! It would enable prospective buyers to talk to current owners, and figure out what they might want before they sink money into the device!
*cough*cough*
Which is exactly what I was hoping to do! Does anyone know if sweep to wake/sleep is possible with the Moto X Play? It's honestly one of the most useful features I've ever seen from rooting et al.
I'll post my setup. Been using it this way for like 2 weeks so I feel it's stable.
I'm currently running this:
Unlocked BL obviously
Stock Canada firmware (MPD24.65-18)
Rooted
Xposed Framework installed
Squid Kernel r14b
I have gravity box installed and that's really it as far as tweaks and stuff.
Averaging 5 or 6 hours SOT down to about 25% or 30%. Really depends on what I do and what network I use. Performance is great too.
I'm gonna mess around with some of this stuff tonight and see what I can do with it.

Hey hey. Thanks for posting!
I'm sure sweep to wake is possible on the phone in some way, likely through a combination of rooting and Xposed modules. I know that GravityBox has a double tap on status bar to sleep feature.
One of the nicest features of the X Play is the Moto Display. It's nice to have the phone screen come.on showing notifications without fully waking the phone. Check out the Moto Display app on the Play Store. It's a totally sexy feature.
I'd say this phone is absolutely worth it for the battery alone. I personally feel the camera to be laggy especially with focus, so consider that if you're a shutterbug. I am very hopeful that software updates will being out the power of the camera but it doesn't have optical image stabilization so blir happens more frequently, at least for me. That could be my shake fingers though.
Feel free to ask any further questions!

Good stuff. Interactive does appear to handle web pages better. I did a Wikipedia search for The Simpsons and got a huge page. I flicked down to scroll it all at once and then Chrome froze. Hahahaba. Same with Lionfish though. Maybe I'm getting greedy thinking this phone is as powerful as my PC.
Lionfish was giving me great SOT results. Like I mentored in the OP: 8 HOURS! Was so happy to see that. Blew the socks off my Nrxus 4. I average between 6.5 and 8 usually, but WhatsApp and XDA Labs are hurting those scores now.
I haven't had to Greenify any apps yet - I only hsvr geeky ones installed anyway so they never keep the phone awake.

I think @squid2 deserves a lot of credit for extending the X Play even further. His kernel and work on TWRP make the X Play even more attractive than it is out of the box.
I prefer Ultra kernel personally because I believe the dev for that (@technoander) takes the latest releases of squid's and adds features to them. I may be mistaken but that's my impression. I'll try to clarify and report back. I should do a direct comparison of Ultra and squid's latest to be as objective as is possible with a subjective test. Hahaha.
I guess I should specify a bit further - sweep/tap2wake is really only effectively useful when the phone supports some kind of low-power state for the touchscreen, otherwise the screen has to remain on in order to use it.
I'm sure sweep2sleep would be possible, but if there's no low-power state for the screen, it wouldn't really matter for me in the end. Moto display sounds like exactly what I'm talking about, though I don't know if it includes any low power mode for the touch features, as well as the display.
I'm gonna look into this a bit more, and see if I can dig up any info. It would be a hardware feature, designed-in, so it definitely should be discoverable. I figure if I can find out all the information for one of the people who have written kernels for the phone, they shouldn't have a problem emulating the feature. It's popular enough, and with the low-power state, shouldn't be too complex to implement.

Cool - definitely report back - it would be nice to know if this is embedded in the hardware somewhere. I hope it is, unlike optical.image stabilization. Damn!

Yes nearly 24 hrs before I had to recharge. As for Row you should notice it with both situations. I use it because of other phones I had before people were saying it was one of the better I/O schedulers.
Actually I have a picture of when I got it. Was nearly 23 hrs not 24 but still.
Hey developer,the banking apps I have does run after flashing a custom rom.Is there any workaround for this?.have to reflash stock after trying any custom rom.Its a pain in the as*.

Actually I have a picture of when I got it. Was nearly 23 hrs not 24 but still.

Row is essentially the best scheduler. Benchmarking is weird, because by design it's an optimized test case and not a use case. Use cases will always be variable, but generally with a smartphone writes aren't too latency-sensitive. That's why Read Over Write generally works the best once your phone is settled, because reading is most of what it does. Doesn't write too often.
There are lots of custom governors, not so many custom schedulers, and lots of suggestions, but generally stock *IS* best, and if you don't understand it, you should not change it. Governors are fun to play with but even they can cause issues if poorly coded. Changing governors will give you a huge impact on battery, but also a relative impact on performance. It all depends on the use context. You'll rarely get much battery life without a performance hit unless you custom-tune settings for your own use context.
As for read-ahead, that value is iconic of exactly what I'm talking about. It is the "chunks" of data that your OS reads in one go. So if it needs 2k, or 2m, it reads a different number of chunks, but each chunk will be the size set by I/O read-ahead. Google likes 512 best. I've been told by the dev for the EX Kernel that internal Motorola devs like 128 best. Benchmarks like the biggest value possible, because they present the OS a massive pile of data and ask it to read it all as fast as possible. In that context, a large chunk size saves time. In most contexts, you read more than you need half the time. So a low value like 128 saves battery and memory.

Hey developer,the banking apps I have does run after flashing a custom rom.Is there any workaround for this?.have to reflash stock after trying any custom rom.Its a pain in the as*.

Android pay does this too, it's a "security" feature built-in by the devs to stop hacking. Not really necessary, but then neither are smartphones, so you take what you can get I guess. No ROM developer can work around this for you. The app is detecting any modification whatsoever. Even root may cause it.

Badass dude. 9 hours SOT is wicked.
I'm finding the phone app drains the battery like crazy. Is this to be expected?
Hey @JohnHorus - thanks for your informative post. I'm currently trying Row 128 and will report back but I doubt I'll see any real-world difference in use. Memory and battery are two soft spots for me so I'm hopeful 128 will maintain solid performance.
Looking forward to reading about others' setups!

Yeah in my experience it drains the battery more then doing other things for some reason. As you can see in my 9 hrs picture I only used the phone for like 2 minutes lol.

About kernels

What kernels are you guys using and why? I'm on stock but willing to try out some
https://forum.xda-developers.com/oneplus-6/help/kernel-t3847767
This thread might help you.....
Currently using blu spark kernel, shifted from EX.
Im on EX. Using the stune boost recommended on the second post of his thread along with top app boost set to 1 so it gets pushed to the big cluster. Ultimate smoothness and no stutters whatsoever. I think the battery drain might be higher with the topapp setting but it lasts me the day anyways so I don't care.
I used bluspark before as well. Provided me with the best battery results but I did get some hiccups with it.
Radioactive was also speedy like EX. Didn't test it long enough to compare to the finer detail but I figured if it behaves similarly I may as well stick with EX since I'm already familiar with the work since the M7 days.

One of the perks of owning this phone it's the insane speed. I've tried Ex in the past, on the OPO mainly, to try to get some extra hours out of a worn out battery. I used to use blu on my N5 for the same reason, I remember enjoying it.
I'm wondering why would someone tradeoff stock

I am using EX kernel specifically because it supports WireGuard VPN kernel module, meaning the VPN connection to my home I have running 24/7 uses less battery and has higher throughput!
That, and the fact I have used EX kernel for many past devices, and the dev flar2 is really active with updates etc
