Thank you this coincides with my observation. I have since replaced twdvfsapp as it gives me better performance in my tasks with boost mode on. When i went with no twdvfsapp i noticed same thing throttling all the way to A7 cores which at temps i was at was unneeded and highly inefficient. Thanks for the explanation I am happy how it is now with boost on and dvfsapp still enabled now that i understand the caveats.

I believe in Andrei's process and I know there is nothing but greatness to come. I agree with you jumping from 600-1400/1600 during throttle is not closely matching its own capabilities for its TDP. I can't wait to see the direction it does take. As is I now know its running full boar with boost and dvfs in all but Antutu (and even in antutu it ia but hita throttle immediately on beggining seeming like it starts at 1.4ghz but I now know it throttled and stays there immediately) and i had more adverse effects removing twdvfsapp so it is back in system. Thank you Andrei and Stone Roses for clarifying the whole throttle mechanism.

Camera failed

I flashed Perseus kernel with WanamLite ROM (removed Wanam's included kernel with Perseus in the zip file), and the camera failed. :( I made clean install of the firmware...

"I flashed Perseus kernel with WanamLite ROM (removed Wanam's included kernel with Perseus in the zip file)"

Sorry for my ignorance:

You flashed Perseus kernel and can use the phone directly ìs it?,or do you have to flash a ROM ,in general ?

In this case ;WanamLite ROM,thats contain Perseus ,so is an error ?,you have to flash WanamLite ROM,nothing more ?

tks gio
[Galaxy S 4 i9500 Original Android Development] Simoleon23:
Thanks but I've already changed my kernel. I'll wait for Andrei to address the issue.

Perseus kernel is not included with WanamLite ROM, the (modified) stock kernel is, at least on V 1.3. What I did was remove the kernel included with WanamLite and replace it with Perseus. Anyways I'm back on stock kernel for now.

Thanks guys for help :)

I was abroad for the last two days, I'll update the calibration and look into the thermal shenanigans in a few days.
[Galaxy S 4 i9500 Original Android Development] mw86:
You are a god :D you should be telling Samsung how to do it :D

I visited the calibration thread and the two of you did some amazing work. I can't wait to see the difference. This screen has some nice potential.

Just thank you for everything. You have made GTi9500 way more than it is on stock.

Btw you mentioned in your tests 1.8-1.9ghz has been unstable. I think it may be more possible after you look into the throttle shenanigans. I went back to stock volt for now and running 1.9ghz for daily basis and task and noticed maybe for bench reasons or full loads in heavy apps the following may be better if users are trying for a stable OC setup.

If each mhz step gets a raise in volt 1800mhz seems fine on 1250mv and instead of 1250 for 1900mhz seems 1300 would be a more logical step after 1250 instead of using same volt. 1350mv for 2000mhz but other than sitting on a home screen or opening a menu 2ghz seems to be the one will never be used. I got 1800mhz in chainfire stable still testing if i can see 1900mhz as stable. After you've got throttle enhanced I think 1900mhz may be stable for many if cpu is throttling to mhz that are feasible for the temp and workload. Certainly most apps under extreme heat will be 1.7ghz stable and we may have a turbo like feel with 1.8/1.9 set as with the raised volt i had 30 stable quadrant runs in a row on 1.9ghz. Using the stock throttle 90c saw even more stability on that clock so it seems very tied to heat as we know all cpus are. Can't wait to see what you come up with.

Keep up the great work Andrei and we will see you when you get back :)

[Galaxy S 4 i9500 Original Android Development] sorg:
Reboots are caused (at least in my case) by unaligned access (in icmp_echo function - you may check your /proc/last_kmsg). Perseus kernel doesn't use workaround for this (used in stock kernel).

I've recompiled the kernel with this workaround enabled and don't have any reboot since that time.

Had a chance to see difference today. Superb job guys it is far more accurate and I am shocked Samsung had some of it quite off. I first checked by setting vibrant which i hate in Samsung display options and then went to stweak and enabled master sequence. Nothing more as soon as I applied i could see a difference. I toggled off set movie and toggled it on again and was a clear difference on there too. Nice work it has more accurate grays for one as it was washed out on movie versus this master sequence. Nice work!

I have this as my home and lockscreen. I took this picture of this beauty while a rain was coming. The colors of everything are pretty nice to check the screen color. If its too vibrant it will clearly look more fake then real. Master sequence is magnificent. Nice work!

Ill provide my image here of this amazing Moth. This was from phone camera, got to hand it to Samsung ^_^

Been told several times... Power Off device... Than power on... I had the issue right after flashing kernel and after 2 consecutive power off's everything is great...

Sometimes the bug repeats itself after reboot do the same again...

Yet again, the kernel is perfect, could not bear stock kernel with my MEA updated ROM... There is absolute difference in heat and battery consumption...

And now with [MENTION=5128949]Slimer777[/MENTION] 's contrubution we have the perfect natural colors. (to be honest, I trained my eyes with movie mod on stock kernel cause at first you feel awkward after so much vivid colors, but now get used to it and today feel the awesomeness with the kernel...)

Starting from MEA, Samsung has changed Settings' background to dark gray. So smearing doesn't exist in settings (and some other samsing's apps). But of course smearing will be present in other apps using absolutely black background.

When i changed nothing but master sequence , register hook and edge enchancement by checking them I saw great quality so I have left this all stock. I don't plan to adjust from here. If you follow Slims post link you could add a touch of a color boost if you'd prefer just a bit more color but keep the accuracy :)

Yes i left midpoints and all adjustments default 0 or what they were.

I noticed at minimum brightness when i started to use register hook it was actually slightly darker :good: and at max was as bright and beautiful as can be :high five:

[Galaxy S 4 i9500 Original Android Development] mw86:
They are not set by default and are there for users who can set them and use some of those frequencies. I don't know anyone who can utilize 2000mhz on this chip for real world application. I have raised volt and had 2ghz applied to see it spike maybe a thread of usage in 2ghz stable, but by all means no amount of adjusting voltage will get me there to be stable for lets say over 25% cpu load via anything. They are there because that's the limit of the chip and users can choose to test and try to get any of it stable. For 1.7ghz i haven't found anything i could load it with that would cause a crash . All setups are different, when the cpu is made it's luck of the manufacture process and materials used. Some silicon just doesn't handle anything but what manufacturer has set to be stock. If you are undervolting 1700+ i would first try to remove that to see if it helps. I would only try 1700mhz first and you may need to add voltage. I've had a lot of tests and games and usage on 1800/1900mhz successfully, but haven't figured if its volts stock are too high so power draw destabilizes or the heat or just handling of the mhz altogether. I think they will be more feasible if Andrei implements a more customizable throttle, so users could find a temperature sweet spot for stability under load for upper frequency. Andrei has already stated he will look into the whole throttle mechanism more. I would try for now staying at only 1.7ghz and try stock or a slight raise to volts for it to be stable. Some chips may only take stock. I have found 1.7ghz for my cpu to not have issues. What voltages are you running?

*the 1800/1900 i usually randomly get a crash on chainfire, antutu, geekbench and some runs go just fine. Using boost mode for the higher throttle temp will make higher mhz harder to get to. User's may want to leave boost mode off if above 1700mhz max.
