[My Opinion] Balancing Features

I have seen a number of questions regarding running Froyo vs Rooted Stock in a single boot or dual boot environment and having tried everything, want to offer up my opinion on the ideal balanced setup between reader features and tablet functionality. IMHO Froyo is still not ready yet as a permanent replacement on the NC and while the performance boost is nice you lose the best parts of the reader functionality.
NOTE: I would love to hear how you made froyo or honeycomb work for you as a replacement for rooted stock.
Soft Keys: With all due respect to the developer, removing this and replacing it with Button Savior is the way to go. Softkeys is clunky, often in the way and (anecdotally) seems to cause system lags. I noticed significantly better system response once I uninstalled it. Likewise, the stock setup often has the required soft buttons available at the bottom of the screen.
Ideal setup.
1.1 Rooted, with 1100 OC kernel.
Set CPU: On Demand 600 - 1100 (a low limit of 300 causes sleep death for me.)
Linpack: 7.977
Quadrant: 1140
SPARK Launcher for that "tablet" look. (missing the necessary customization features, but I expect that will be improved over time.)
Benefits:
Full NC functionality (magazines, Newspapers, kids books)
Nealry complete android experience
Email, Gmail, Corp Calendar (motocal), corp address book (motogal), youtube, Pandora, etc
responsive and zippy
fantastic battery life (remove the telephony apks.)
Cons:
no flash support
limited video codec support (probably a way around this.)
wifi reconnection can be a little laggy (I don't use an app to keep the wifi from sleeping to conserve battery life.)
ADB requires a couple extra steps to work with everything mounted properly.

What is the advantage of HC over others

What is the advantage of using android 3.0 have over 2.2. and 2.3?
Install all three and really see no difference beside the slight UI changes.

evilPERSOn,
I had not yet loaded HC, so my advice is pure speculation. HC has an entirely different interface which acknowledges the fact that a tablet is in essence a tablet and not an oversized phone. So, as such, it works a bit more like a computer with. The speed and streamlined interface of a tablet. As I write this I really wonder why I have not cobbled it up. Well, it is only a matter of time.
Have fun

well for starters this should be in general not development
second HC isnt just a slight UI change, it was MADE for tablets so if you want your tablet to be a giant itouch running android than install 2.2/2.3 but if you want a tablet you should install 3.0

^My bad. I had two tabs open. General and Development. Must have started thread on the wrong location.

1. HC uses GPU interface rendering.
2. HC is meant for a system like a nook with few buttons (good for us)
3.But HC's source is not in the open (bad for us).

Hopefully the source will be released soon!

For me i thought i would try hc on the sd card and just go back to froyo. I was hooked. I used it for two days on a class 2 card then i flashed, and ive tried to go back to froyo and get flash but i cant. The UI is just perfect, the live app switcher key is wonderful and so great to use, probably my favorite feature. Not to mention i love that the task bar is on the bottom, reminds me of windows and keeps the clock and keys out of my face. Honestly i hate the top notification bar on other versions, ive always hidden it on my droid. Being on the bottom is so nice and out of the way.
Its got its downsides, but give it 2 months.. apps galore, source files..... it will be really good to run.
Edit: not to mention, ive never lost data like on my droid while switching apps. Ive come back to apps ive had open for over 24hrs and its still in the same state

i'm using the samuelhaff's eMMC HC and i noticed that i can't scroll the app switcher, so i don't have access to all my previously run apps. is this normal?
loving HC, so far. the fact that it's designed for no hard buttons is just awesome.

i don't think the app switcher even scrolls on the xoom yet.

I have only played with HC breifly. But from what i know about it these are the following reasons to use it.
1. Market. Honeycomb is the first android os that will support having the google market. This provides a few things. Any of us who have played with Ipods and ipads will know that there are specific apps built for ipad. Now that Android 3.0 is built for tablet form factor, and officially supports the market. We will now see Tablet applicatons that provide higher resolutions, or new features. These apps will be built around the 3.0 os, and may not work on older operating systems.
2. Built for tablets. Everything we have had up untill this has been a phone operating systme built for a 3" screen ported to something with a 7-10" screen. The os is clearly built for phones there are things in there that just dont work right, or should not be there, but are there, on a fundimental level in the operating system. By adding native support for larger screens, and removing the phone items, it provides for a cleaner higher performance interface.
3. Interface enhancements. The UI has been built to support the larger form factor. This will provide easier navigation as well as soft keys as mentioned above, since alot of tablets are just missing physical buttons.
Unfortunatly the OS has not been released to the public. My guess is there is some contract between motorola (xoom) and google for exclusivity on their tablet. but dont quote me on that.

1) The web browser is much improved - even over Dolphin
2) The email client is much improved - even over K9
3) Contacts sync seamlessly with Google contacts
4) The keyboard is much improved - has a TAB key, has a "handle" to move the cursor around in text, has cut and paste features.
All of this is enough to make me swich to HC.
Downsides:
1) Many of my favorite apps cannot be found or downloaded from the Market - even though they worked fine on 2.1.
2) From uSD card, runs a little slower than 2.1, but not enough to bother me.

is the video accelerated? I could not take cm7..so slow.

No. Same problem effects both I think.

Well, I switched and got my nook to recognize the sd (Class 2) partition. I expanded the image to use the 16 gigs too. I love it. The Live App switching is nice. It actually feels more like true Linux (I am thinking KDE) than any other droid system. I just can't handle the lag when booting apps (probably a combination preview/sd card). I am a teacher and grade on my Nook, so I need speed. But, I am excited about this. Thanks a lot Deeper Blue. This will be stellar.
The true app switching is almost priceless as is the efortless interface.

Nexus 7 Grouper Custom ROM Memory Usage Comparrison

Hi all
I very much doubt this post belongs here, but since i am a new member , have no chice but to put it here.
I have recently accidentally purchased a nexus7 (grouper) and decided to try some of the custom roms available, in the end i tried most of them.
Here are my comparison results.
As with all things putting an "order" on the roms is subjective, the "best" rom is the one that works for the individual,with that individuals particular needs and wants.
As an embedded design engineer i am obsessed with speed and efficiency, memory usage, putting as much data on the screen as possible, then finally compatibility and lack of bugs ( in that order ), my results are biased by that order.
Disclaimer........
1) Ok i know that android is not exactly ideal if looking for an efficient well written os ( who the F came up with the idea of running everything in a VM!!! a minimal linux system will run in 85 mb ram with a full xserver, android STARTS at 400mb+, sitting there doing nothing !!!, thats near my cut down windows7 running on an i7 ) but before a decent linux distro is ported to full touch am stuck with it
2) For the N7 the requirement to change the DPI is essential, it is VERY stupid that the os does not check and change this automatically, otherwise its like having your 1920x1080 monitor stuck on 1200x600 permanently, very stupid !!! So am assuming the roms without this facility will function at 160dpi correctly, i have not been able to check this for every rom
All roms were flashed by TWR ( latest ), wipe of cache, dcache, factory reset, system
Memory was checked by settings>apps>running , immediately after first boot, then after a clean reboot, then after a cache,dcache wipe and clean reboot
IMPORTANT NOTE.....
Google apps ( gapps)...... in terms of memory usage gapps is the worst peice of #%%#%%$#$% sh$%^%$%t bloatware i have ever encountered in my os experience ( and given that i spend most of my time in windows, that saying something ).
On any of the roms i have tried flashing gapps adds at LEAST 150mb of unneeded memory usage, and depending on the rom that can go up to 250mb. Even using a minimal gapps with only phonesky,framework,login and setup, still produces a significant 50+mb hit, unfortunately in many cases some of gapps is essential, and some os functions are broken without at least the framework.
This situation seems unacceptable to me, all the roms should function correctly without gapps, and without the bloat, if some dev does not address the situation i will.
1) Prime Grouper D03-06
Tablet ui...... yes
DPI changer ...yes
Size custom nav bar ....yes
Speed....... good
Response ... good
This is first on the list for 1 good reason, memory usage!!!
Before flashing any kind of gapps
First reboot 360mb
Second reboot 320mb
Cache wipe reboot 270mb
Subsequent reboots 266mb ( stable )
Obviously team Vanier know their sh**t, their os is running in nearly HALF the memory space of other roms , and on the whole with few bugs, but whats really impressive is the memory usage is incredibly stable for a android os, zero memory leaks, leave the device at 302 mb ( say you opened an app and it was cached etc ) for 24 hours check again and lo and behold its still roughly 320mb ( obviously internal processes are moving this number a little but only by <>5mb ), this is not the case with stock rom or many other custom roms.
Everything is not all roses though, using prime without flashing gapps at all, exposes quite a few bugs, notification panel does not work at all, clock settings is broken, a few apps fail ( mx player fails for a start ) and others.
Flashing a super minimal gapps, fixes most of the issues, notifications are back, a lock screen turns up, all the settings appear fixed, BUT it also knocks out vanires keybord and totally ruins the memory handling
After flashing "micro" gapps ( and going through setup, adding valid account etc )
First reboot 430mb
Second reboot 360mb
Cache wipe reboot 320mb
Subsequent reboots 360mb ( NOT STABLE, can vary up to 400mb+ with time )
Obviously would love to see PRIME fix the outstanding bugs, and produce a custom set of gapps apk's that dont screw this fine rom.
2) Smooth ROM v5
Tablet ui...... yes
DPI changer ...no
Size custom nav bar ....yes
Speed....... good
Response ... excellent ( the best )
Gapps are included
First reboot 470mb
Second reboot 4200mb
Cache wipe reboot 400mb
Subsiquent reboots 440mb ( NOT STABLE can go 500mb+ )
This rom is second due to a totall lack of bugs, after much mucking around i can not find a single setting or feature that does not work correctly, plus the UI is very very responsive, the best of all i have tried. It would be top but for the lack of a DPI change option and the fact that memory usage is nearly double that of PRIME.
will post the other 20 odd results later

What's more interesting is that identical apps on the galaxy S3 take up 2-3 times more memory. 1GB is fine on the N7 but you have to do a lot of fiddling to get the S3 running with 1GB. Must be down to the Tegra architecture. Smooth 5 runs great on the N7 (especially with greenify app)

3) Cookies_Cream-1.3.1
Tablet ui...... yes ( built in as standard )
DPI changer ...yes ( 160 dpi native )
Size custom nav bar ....yes
Speed....... ok
Response ... ok
Before Gapps
First reboot 560mb
Second reboot 560mb
Cache wipe reboot 560mb
Subsequent reboots 560mb ( stable )
Although a memory hungry beast this rom is optimised for the n7 resolution AS STANDARD, you get full true tablet ui, AND with the PARANOID ANDROID framework, it is ultimately compatible with any app at any resolution, and best of all it all works!! no bugs that i can see, although memory use is very high at least it is quite stable before gapps.
If you want the full tablet experience out of the box then consider this.
I have not tried a memory test after gapps, 560 was too high for me without gapps let alone with
4) BeatMod_CrystalClear_v2.3.zip
Tablet ui...... yes
DPI changer ...no
Size custom nav bar ....yes
Speed....... good
Response ... good
Gapps are included
First reboot 480mb
Second reboot 4100mb
Cache wipe reboot 400mb
Subsequent reboots 440mb ( NOT STABLE can go 500mb+ )
being pure CM10 this one is very different in style to the AOKP based roms, but is almost identical to smooth rom in terms of memory usage, although less responsive, on the up side is packed full os sound enhancing mods and an upgraded bravia engine for video
the rest are in no particular order

You got it! There's a huge difference between the gingerbread days and now, i remember when my droid eris would use 200 megs of ram for the OS, now.....its a lot more. Why do you think new devices are getting 2gigs of ram, I'm guessing key lime pie will only use more and more memory to give us a better experience

Hmm have to take your word on better experience having just come to android.
PRIME runs at 266mb without gapps, thats a bloody good number for android, just needs the bugs fixed and a minimal/mico ( just playstore functionality, without the paid service ) gapps integrated so all the settings etc function, then we are talking as good as it gets with android.
Generally if you want something doing do it yourself but in this case am in the middle of becoming proficient in c/c++ ( again , its amazing when buried in hardware, pcb design, spice sims, matlab etc etc that one can just forget how to code, i always thought it would be like riding a bike WRONG! ) so learning java from scratch is out for at least 6 months, am very much in hope that PRIME does it for me ,

Before you go any further you should define exactly what you mean by "memory usage".
I challenge you to correlate your "memory usage" statistic to anything you can find in /proc/meminfo.
Go ahead, give it a try.
In any modern OS - including Android - 100% of DRAM is in use. The only thing which remains is some quibbling about whether you should give up file cache space for process memory space or kernel private memory, and the answer to those questions always depend on the nature of the workload.
The whole of dalvik is built on top of native shared libraries that are substantially smaller than the totality of shared libraries present in (let's say) a recent Linux distro. They can be memory mapped in copy-on-write or read-only fashion to a large number of process spaces, and so in fact it is a strategy of the "system_server" process to preload most of them. That way new activities spring to life quickly, rather than being required to demand-load and link everything from scratch.
Bottom line: it is an intentional strategy of android to "use up memory" right from the get-go. Most of that "used memory" is shared libraries that are mapped into activities as they come and go.
So, would I want to run engineering applications that require 800 MB of heap space on an android OS tablet with 1 GB of RAM? The answer is clearly "no" in that case, but mostly because Android devices are not targeted for that kind of work.
For comparison, BTW, my Win 7 x64 box that is nearly bare of applications (I only use it as a VM host) needs 1 GB of committed page space to sit there and do nothing. Android isn't doing so badly in comparison.
cheers

Hmmm
Well lets start with the last first, i run a heavily customized ( rt7 lite, wintoolkit, buclean ) windows 7 ( EE edition which i mastered ) on a asus g15w i7 8 gb geforce 470 , with all drivers in, on full aero , <>560mb mem usage for the system, can go down to 500 if you disable the nvidia startups and services but you lose the nvidia controll panel.
I totally take the point that memory usage in modern multi-core systems is friggin complex, obviously these memory stats are not supposed to be definitive in any way, but given all the tests are run on the same hardware with the same inbuilt prog they can be used as COMPARATIVE results, ie you can say rom x is more efficient than rom y given they do the same thing but with different memory results.
By definition any code abstraction away from 1's and zeros makes that code less efficient, an entire graphical os can fit into 1.8mb if written in x86 ASM, same code becomes <>20mb in C, 25mb in C++, 80mb+ in vm bytecode, the same pattern can be found in mem usage.
Any virtual machine no matter how clever ( and dalvik is bloody clever ) is a glorified interpreter, hence slower ( by a few factors ) than c/c++, which is itself slower by a few factors than ASM.
My opinion on caching is DONT, unless someone comes up with a really psychic piece of code that can for real predict the chaotic needs of the average human, all caching algorithms are just guessing, and do i trust the system to free up all that memory in time when something ( as you say ) calls up a massive heap or worst maloc's it direct, errrr no.
But thats just an opinion, am totally willing to recant if i see evidence and accurate benchmarks to the contrary ( and you seem to know your stuff, so if im way of the mark please enlighten me ! )

[Q] _ Will CM fit my needs or is it over kill ?

I would like to know if CM is needed to do the following or if there is another way.
(Ive only had the Nook for a couple weeks, not sure whats out there)
1) Use a USB thumb drive for MP3 storage/playback. (found this)
2) Hooking the Nook HD to my TVs HDMI port.
3) Possibly use a blue-tooth keyboard
Currently i use:
- Google play for programs.
- Download ebooks and pdfs from alternative sources but do use the Kindle app from time to time (but have that installed on a PC along with Calibre),
- Dont think i have used the B&N app for anything yet, so if that is lost, it will not be that big of a deal (would be nice to have it though).
Alittle background:
I am not new to "flashing" a device, but is there is no need to then i dont.
Ive had an ipod for years running RockBox (and love it)
Been running a ubuntu based server and desktop for a few years.
Any suggestions or guidence would be great.
- thanks...

In case it helps others...
I installed CM 10.1.3
1) the USB storage worked great as per-link above.
2) have not tried
3) tried a Logitech MX5000 ("desktop") keyboard just to see what happens, they made the hand-shake but nothing after that... i did not try too hard.
Found a B&N Nook (the green N) app (.apk from an alternative site) and it seams work fine.
Dont know if you can get the USB working with-out CM, but it works great with it.

A key issue with stock Nook rom is performance. The library sync is a resource hog and randomly results in stutter for apps. Movies, games etc. it also results in battery drain.
For this reason alone, stock is best served a quick death. CM 10.1 and Nova is a good combo and then in performance settings: Turn on 16bit transparencies and set ram to "purge assets".
Added: Any other performance settings appear to actually downgrade performance.

Where are these performance settings located?

You go into About device and tape the rom version several times. I think that is it to unlock it, but a quick search will get the right steps if wrong. Need a non stock rom to get the options.

Elite Performance

I have spent crazy amount of time tuning my Galaxy S5 G900F running the latest CM13 release with the stable Boeffla kernel and I finally think I totally mastered the performance level at perfect stability without any overheating issues or crashes.
I just got a splendid 64676 score from the latest antutu benchmark! That is way higher than any old 32bit Snapdragon 801 device has ever gotten and the RAM and I/O performance is just ridiculous that beats much newer and more expensive phones.
This is enabling me to play VP9 videos at 1080p completely smooth without any drop in quality or FPS. The best part is that the phone newer overheats or lags. I can run some serious multitasking and download at least 8 files simultaneously from 8 multi-threads at blistering speed including complex merging, decoding and encoding procedures just fine and using the phone for common tasks in the meantime.
For those who want to be able to shoot 60 FPS 720p videos get the Snap Camera HDR app and with correct settings that will be quite possible. Just let me know if you need instructions how to set it up properly.
I included a screen shot of the benchmark score.

i confirm - cm 13 last nightly releases really fast and stable, i try boeffla now
i think it the best performance rom on s5 now

Thanks, I got a s5 a few weeks and didnt know which rom choice. I'll try cm13
Enviado de meu SM-G900M usando Tapatalk

Reliability test complete without any notable problems. Ran another antutu test and got 64k again. So now I'll post my setup.

I have a very clean setup of CM13 and chose the Pico Gapps version and also have xposed. So I only have the most necessary apps that I want to use to reduce all weight on the system. I also use the recent apps task killer when ever I'm done with current tasks to free the ram for next use. I hate the low memory killer because it stop certain background processes like arkTube so I put everything down to 5 and use the task killer myself.

I'd rather go with the latest release because there are still few glitches left like soft reboot does not work properly. Use stable kernel for release and beta for nightly.

New high score record for the S5 with the 3.3 kernel running CM13. Going to try CM14.1 next.

Please help I'm a noon
OK so I just read your thread and I wanted to ask a few questions but before that let me explain to you that I'm very new to costum kernel and costum rom stuff. First question what's your best recommendation for the fastest stable rom (currently updated). Second question you said you will go too cm14.1? Will that be a faster and better than the one you metioned in this thread? Third question if this is the best tweak for the s5 may you provide links to the programs you used to do this and possibly a tutorial if not it's cool I'm usually fine doing this kind of things on my own, a little guidance will be helpful though ? Sorry for being a noob but could you please help me out I just rooted my s5 (SM-G900T) and download set cpu but I've read that it won't work unless you have costum rom/kernel and thats why I'm asking for help. Please and thank you.

Great job! Do you use new Adreno drivers or rather stick to the old ones? And, do you have your camera working? I'm trying to replicate your setup and the only thing that bothers me is the camera error....

Im on cm14.1 and got 48470

And how about battery life? That OC to 2.8Ghz looks like a battery killler (to me at least)

I made sure the setup is totally interactive. It only uses a lot of power when under heavy load. The hardware goes in deep sleep when the phone is not in use.

As you can see in attached screenshots, one third of of the device's on time is in deep sleep. Input boost is on at highest settings and CPU/GPU locked at max frequency when under load so responsibility is quite good. The main power drainer is the screen at high brightness or heavy multi downloads or gaming mostly.

The screenshots. When it goes under heavy load it throttles down and up various frequencies to protect it from overheating. So let's say I download 500 files, 8 files simultaneously by an 8 multi thread method at above 120 Mbits the CPU goes under heavy load, a lot more frequencies would be used because of the throttling.

Here is a link to my Setup Demonstration YouTube video where I show the tweaks I've done to improve the performance of my phone:

I uninstalled the AdClear app because it just was too recourse demanding and network speed trap. Instead I installed the latest version of AdAway and configured it so ads in all the apps including MX Player successfully and free of VPN and system load. I attached screenshot of the configuration.

Where do you get cm13?
