[T-Mobile Samsung Galaxy Note 3] Absolon:
The copy-writer is back ;)

Hello. sorry for my absence. Since I'm the master of long posts here comes one ;)

I did the "pull the battery" and it works now. The old trick still holds! :D

The reason why I didn't continue with HTC was just their stupid move with no SD and no battery without using a screw-driver and my "old" (2 years is old, funny) HTC One X is soon in need of a new one. I'm guessing that sending it in to HTC cost about the same amount as their latest phone... But never again Samsung.

I guess you mean "sync_freq" in interactiveX? It's set on 1036800 as plain vanilla. Have not really played with it so I have no params to go after.

Maybe go for another? Or is there any resource page? I have not played with the values for ramping on the phone since its quite different from

a PC that you seldom have to mess with that. Just switch to Gentoo or Arch! And I also know that they can do havoc on your battery life.

I'm after smoothness in what I use it for and no lags and no hangs (got a few of those from time to time, but that might be Xposed mods since I installed that a few days back and there are many that have the same things (together with the things already in the rom!).

Please please, don't incorporate it as some has done. You can't upgrade it most often and its never working (I have gone through almost every rom there is here before this... All the TW is just the same same same). Else it's kind of a good framework except for the constant reboots that brings back Win95 into memory (and Win 8 & 8.1 that took it back on users request).

----

I have not tried to play any movie (nor game). I think that at the most I tested Youtube once over 5-6 years. Me? Boring? No ****, haha :p

If I'm right that you are asking if it lags while I play it? If it does when I "just" stream then it should be the governor?

If I play something of the SDs it points to the I/O-scheduler and/or something with the buffer space, right?

Cause I'm thinking like this and please correct me if I'm wrong!

I read that Snapdragon 800 should be able to natively play 1080p (well rather 1080ip24-30) but is that the GPU that decode it?

I have no info if it's Adreno GPU that decode the whole thing (good) or if the CPU's need to step in (BAD). MP4 can sometimes really eat bandwidth and H.264/AVC (that is used everywhere, think even Youtube uses that now) can be a real killer (but isn't it quite utterly useless on our tiny screens?). Normally it needs to render 3-4 frames ahead, the reference frames, the "look ahead" and the actual decompression of it all. Especially if you have a movie with a lot of block changes, like fast action scenes (thinking more Arnold in T3 then in Kindergarten Cop) it can easily go up to 10-20 Mbit/s and if you have a higher picture standard like up to 150 (don't think my disk would do that). But that will "eat" some cycles somewhere. And battery for sure!

The internal storage have 140/75 MB/s speed (looked it up, NAND rocks) and the external does still not support faster ones that Class 10 (right?) and Google seems to hate them for some reason. Sure give me a phone with 128 GB internal for the same price then!

The best max 80 but I at least can't afford those so mine are in "theory" 40MB/s but in practice max 20...

So I guess that streaming only touching the RAM can render that better quality (but who want to see Keanu's pimples on his nose in Matrix?).

But if the cpu's work red hot and are not only doing the presentation layer that is bad. How is the reality, since I don't know?

Since I don't know the I/O implementation in our phone/chip (see crazy note at the end). If you calculate that even 20 MBit is not more then around 3 MB/s the external SD should be fine as well. But it have at least pass the I/O of the kernel once since it need to access it for the GPU or if they have some own bus for that?

Buffer

Most programs have a limit of ridiculous 4kB is the I/O-buffer, but I guess that is a build.prop?

Here I take a guess and say that it need to do one I/O once for a read. So 4kB is kind of little. And since we have a buffer, won't it grab that first since it's in the memory and some other worker process fills it up again and we end up in doing that 3-600 times/s even it it's a ring-buffer it's the same principle since it need to fill it. So just that costs us ridiculous wasted time. We have 3GB of mem, 4kB???

(300 is less then 3 ms so if it does start before max 15 ms that's fine since the max frame rate of the eye/brain is 15-20 ms /Dr.Abs) :laugh:

I would need to do an strace here. Oh, I can't since 4.4. It's blocking "the almighty ruler, stronger the Putin" user named root from touching some processes!

At all

! Root can do anything! That is why you have sudo on Ubuntu so you can do a "sudo bash" ;) (sandboxed?)

Well. and off-topic mega-answer and if someone but you got me thinking (WOW) and I wanted to ask the ones that DO watch movies to whop up the buffer to say, 20-30MB? Just to see how it will affect the rest of the phone because right now it feels like we are just wasting instructions

on something that runs out of buffer, changes to the card while it waits for it to fill up, then do the same, and in the worst case it will just stall with a "wait". That is a HUGE penalty. For a parameter (that I have not looked up the name of yet).

If someone can whop me in the head for faulty logic or some misses I made at 5:30 am then use a pillow, ok? ;)

I kind of like this thread. No elitism. People tend to forget they where newbies once upon a time and was tish-scared making the first post.

I got a low life when I wrote my other. Good for me I've sitting so long before a computer that my hands grew anatomically to a perfect keyboard position :P

Having 4000 posts doesn't mean that person have a vast knowledge. It just mean that they are good at bull****ting on a forum ;)

Oh, I can't find the power-saver anywhere? I came home with 3% left :cool:

/Absie

Post scriptum magnus maximus

Btw, I looked at the dmesg in the official Samsung SHIPPED v4.4.2 kernel...

Has a thread that get kernel panic that they just ignore.

Loads of script errors because they have not set the PATH right

Loads of other errors of not finding stuff or get "segmentation fault" on that they just ignore.

They mounted ALL the disks (ext4) with -nojournal -errors=ignore...

Wonder how many clock cycles they saved on that with a default buffer of 512 bytes?

After a normal reboot it had to do an fsck in /system with 3 lost files...

They could have run it on FAT16 since it would give them as much security. Or btrfs v0.001.

It's a fcuking wonder it starts!

This is not the end. This is the note in the end that is larger the the beginning (Oh, no. Not that crazy Swede again! But then you can skip it :p)

I read on a board (doing hobby electronics) and saw a discussion about Qualcom and their strange ways and a bunch of people started to check other NOT Samsung phones.

In the "normal" world of buying SoC (if you don't rape a Raspberry Pi) is to go to different companies webpages and look what they are boasting about of released chip's that are awesome. Like this: http://www.altera.com/support/devices/cyclone-iv/dev-cyiv.jsp

The manuals are like phone-books and always accessible (You HAVE to have an instruction manual that tells you how to put it on a board, so you can actually build something with it without thinking "hmm, wonder what pin 182 is doing? Let's hook some juice into that one!".

I think that is clear as water, right? Like now, that it would be nice to know if it's doing one or two I/O's (or zero) when moving data from chip to GPU?

Like when DMA came to the PC and the CPU didn't have to manually move data from the disk to the memory. WOW! Speedup amazing!)

It's things like that you can find in those manuals on page 748, if you find the right one of the 1839 that are there!

But Qualcom guards those like it was military secrets or if asking for the manual for Snapdragon 3000 Turbo. There are none on their site and if you ask them they will not give it to you. Kind of strange right? Feels like they are hiding something. Maybe an e-fuse?

Knox

I'm sure that some of you where on the S4 before so you know this story. Knox has been there a long time. Just waiting to get "armed". It must have taken them quite long because I think we found some rudimentary things on the S3. I got quite involved in this since I got so much information. I got obvious users that was from Samsung messaging me and when I was asking here for a "De-la Vega" phone I think I got so many offers, from juniors, created after the post and one that went there in that post and said it was just fine and we had a private convo and I told him a blatant lie that he corrected me on. Now how could be possibly know that? So I rooted out quite some Samsung'ers and again, if you take a peek in that 600+ pages, still ongoing discussion about where it is etc, you can search for juniors that just have 1-2 posts and one of them is saying there that they got a friend's mothers brother who just went to the shop and they just did a "Triangle away". When I offered money to give me the name. I think I even offered him a car (a Polish Fiat 126p) they just vanished.

Incident

There was a leak (WOW, from Samsung??) of the 4.3 and all grabbed it of course. I think it was pretty unprecedented that Samsung "leaked".

Not like HTC, Sony that leaked on purpose to see the bugs being reported here, and wow, are we monitored. I think they have just people that sit and search for posts (Hi Steve!) because when the wizards hooked up their electronics and found that it was most probably an e-fuse there was an statement on Samsung homepage like 3 days after that (one, that got changed about 5 times. Thank you Google-cache!).

It got a new boot-loader and something new on their screen in Download mode called Knox. Nobody knew what it was. So when people begun to flash that flag turned to 0x01 and physically destroyed quite a bunch of S4. Badly. Some where just trash, and I collected "things" through mail and I think I had like 40 different things, depending what serie it was, country etc. And that was integral parts.

Most common was that the Wifi stopped working or got in a worse state then on Note 3. Memory "disappeared". Installing old modems didn't help. Very very internal things. With attached code. That stopped Google Play to work. You could install Samsung things fine but other things got very strange errors. You had to wipe the phone but the boot loader was stuck. Then it turned out that each phone (as yours) have an unique certificate that could identify your phone. You got "upgrades" pushed while having it turned off. And people dug some more. Dumping a phone, just reading and coming to a certain address destroyed the phone for good. Hard bricked. Nothing.

Target

I am 100% sure this was targeted at the Top 50-site with enthusiasts that sit and want to have fun with their phones, XDA. It was a perfect

move.

No warnings, no documentation nothing, until a few weeks later a rudimentary page in Drupal came up about this business thing called "Knox". Not like todays with blond cute little girls and some green grass, all happy, talking about family security (how can you install a firewall without root? Or backup? Or anymalware/spam/block permissions of "too hungry" apps? You can't do that without root and that is why you all here chose to root your phone. When we questioned why it was on our private phones we where ignored or got a letter from "Steve".

We compared it. From my cold Sweden to Singapore. The same. That they could not give any info at the time being.

That is why I got so involved with Knox (if you would happen too see my former posts or my sig (will change that). We have since then been a few that has taken Touchwiz apart and for that we got hold of phones set to Enforcing more but with root. And we concentrated on the Note 3 since it had the 4.3. We will probably post all we found, but too much work and too little time has not got us ready.

But our phone had some really good stuff. I will just tell you, you can find the snip of that code in the I9506-forum. But it was so much references to 3 letters you wouldn't believe. They where cleaning and preparing the merge with the "NSA-version" and had comments like "Remove this device, already defined by NSA". And here we are. Version 4.4.2. Not a word about NSA, so I guess the merge went fine?

And here comes the comment from above. If you know Unix/Linux you know that root can just do anything.

You can skip this history lesson if you want

Unix was written like 1973 when the C-language was finished (and is still used. Look at the Linux-kernel. All C!) and the main parts where coded around 73-80. So some commands that we use in a terminal are 40 years old! Of course, ls has 152 parameters, but the sudden rise of tar, that surprised me. Tar is for Tape Archives. The only function was to read, write and seek on a tape! It have evolved and always being used on Unix but I never though it would get such a renascence. I once read out a tape on an ancient machine that had those rolls. That info was 20 years old but needed and it was so easy! Tape is still the biggest media for backups and I've been on a place where there was personnel working with one thing, rolling tapes so they wouldn't stick! All day! So don't think your job is boring when you have a room like a basketball hall with those dusty rolls of tape that are older then you but still contain critical information that certain places need to store for at least 50 years!

Back ;)

But they have done something. We know that there are ways in to the phone since they can push "updates". Our phones are not safe and has a lot of bad spy movie with Kevin Costner in it. That is why I was looking for a real nice "Non Touchwiz"-rom. I hope it helps. In the biggest heat between me and Samsung, if I didn't reinstalled my phone with the sim out and the first thing a firewall, my phone started to act up after a little while. Programs got uninstalled, icons still left, again Play errors etc. And I am not alone. I've shown the code to some really deep nerds. The ones that didn't has AOSP installed that and taped the front camera over, because how often do you use compared to someone else, really?

Now the S5 is here. So smart! Collecting fingerprints for free!

If it was so easy to remove their biggest security "invention" that as a thank you for populating the world with our rom and capabilities installed get the contract to sell phones to the US Government it would NOT be in a side chip. It's integrated. And I wonder that when they get that clearance, will they equip it with a Snappy or with their OWN CPU, Exynos? I wonder why they can't make it LTE? Isn't it on pair with Snappy?

And Qualcomm are still refusing to give out plain instruction manuals...

And yes, a nobody.

And yes, I'm crazy.

And yes, I wear a foliohat.

(Tired of making watches in my Igloo, having my polar bear night-watch, harpoon a whale with my mates take their kids out on the regular Sunday trip clubbing some baby seals).

And then I don't remember what I am cause I am so much in those posts...

But I know that I cause havoc!

I think you have seen my tag that Samsung and me have broken up quite hard (those guys had REAL penal complex).

We are strongly thinking of releasing the findings. Too bad that Qualcomm turned out to be together in it NSQ ;)

- The end Part 1 of 823 ;)
