it is not wierd... there are several variants i guess.. mine is all diferrent... with less default values... and afaik mw86's is whole different with much more higher default volt values...
[Galaxy S 4 i9500 Original Android Development] HassanM:
I'm using Omega v9 / Perseus 5 / Crossbreeder....

I've noticed my Smart Scroll feature isn't working... Assumably Smart Pause isn't working either...

Although all the features under Smart Screen are activated... Moreover that Eye icon is always present on top of my screen (greyed out) and changing to white at times.... Somehow when I'm browsing on my Stock Browser, I don't see that little Green Eye popping up on my screen...

Can any plz advise...

Thanks

Im not using stock, if Im not mistaken I think I did a 50 uv in each step, I havent tried more. Can you post yours just to compare?
[Galaxy S 4 i9500 Original Android Development] zetlaw:
that's why i wrote Default values.

in Stweaks you can see your current value and default. default values supposed to be the same for everyone. but mine differ from yours.
[Galaxy S 4 i9500 Original Android Development] Nghtmare:
My bad I hadnt seen that it actually shows you the stock values, I just seen them. Well maybe its because thats how the chip was made I dint know, but it does make sense that they all should use same voltages even though from what I can see it doesnt work that way.

Have I found a bug? Maybe by design but if I change max frequency to use = 700mhz (all other settings untouched) it applies ok but when I press the back key to exit stweaks the phone freezes and I have to hard reboot.. anything above 700mhz is ok though. I haven't tried to apply in setcpu or similar I will try that next.
[Galaxy S 4 i9500 Original Android Development] acidmoder:
I got that bug too! I found a fix by manually changing the "up step level l" to 700000 in the governor settings - used SetCPU. I worked out for me:good:

[Galaxy S 4 i9500 Original Android Development] AndreiLux:
This version isn't the "**** I had to do" I had in mind 2 days ago, there I had to deal with unsynchronized controller engines and did some ugly hacks until I came upon the miracle of synchronisation triggers. The chip basically has some SRAM memory and you have to load a microcode program into a controller engine for each LED.

Least to say, that was an interesting/frustrating experience.

Thanks for the gift.
[Galaxy S 4 i9500 Original Android Development] cmd512:
I had an inkling this implementation was nothing like the S3's as there was a funny bug in Lightflow that didn't exist with the S3: If you set "Fully charged" to "LED always on," the LED would refuse to light up at all. So, I had to set a workaround by using the custom timer, setting it to "60000,1"... which effectively had it stay lit for 60 seconds, and blink off for 1 ms, and repeat. If you set that second value to 0 (which is "always on"), the LED would again refuse to come on at all.

Then, a bug / limitation was discovered with the custom setting also: Any value above 60000 (60 seconds) seemed to be a complete waste of time as it would still blink off / on at 60 seconds. Anyway, hokey stuff going on with this controller, that's about all I figured. Good news is, with alpha6, I can set it to "always on," and the green LED just stays lit as expected.

One tiny bug I've noticed: For my LINE messages, I have a light red notification selected under light flow. I just noticed that when it fades in, it's the right color. But, when it fades out, it turns to a solid red color. Any ideas why that might be happening?
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
That's simply because the driver ignored requests for 0 off-time. I fixed that. It should also be more battery-friendly than your "workaround".

The 60 second limit is also some arbitrary limitation, but I didn't bother to change it since it seemed senseless.

Eh? Shouldn't it fade off? Don't quite get what you're saying. Works fine here as far as I can tell.
[Galaxy S 4 i9500 Original Android Development] cmd512:
Hah, I figured as much. Good to know on the battery bit, although it only did the quasi-solid light when plugged in.

Heh, let me clarify: I have this particular notification set to a light red color. When it fades in, it's the proper light red color. However, after the retention period at max PWM, it turns to a solid red color when fading out.

UPDATE: OK, tested a bit more with the forced LED test under Lightflow. Seems to be anything with red in the mix: Blues seem to fade in / out perfectly.

Light red / fuscia = fades out as solid red

Purple = fades out as solid red. And, during the "lights out" period, the solid red remains

Gold = fades out as solid red

Weird!
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
I don't get it. What does light red and solid red mean for you. In hexcode please. Of course it gets darker when fading out, that's in the nature of fading out.
[Galaxy S 4 i9500 Original Android Development] HassanM:
Good work Andrei...

Just flashed Alpha 6.... LED integration is really nice....

Keep it up and good luck!!!
[Galaxy S 4 i9500 Original Android Development] jlevy73:
This is a great implementation

I am also getting some weirdness with non-stock apps. For example, I use aqua mail and have the LED notification set as blue. When I get a notification it blinks blue then when it fades out it turns solid green. In STtweaks I have the settings for Green set to 0 so wonder why the LED is turning green when it should be fading off?

Edit: Not using lightflow, just the in-app notification setting to set the color of the LED
[Galaxy S 4 i9500 Original Android Development] cmd512:
About to catch a plane for a business trip, will post once I land. I understand the confusion, but no, it's actually change colors (hexcode if you will) when fading out.

(I'm not misinterpreting the fade-out if that helps.)

Will advise shortly.
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
Does the app have flash timing settings? Reproduce this: in STweaks: Fading on 300ms in, 1300ms out, 350ms retention, 4000ms delay, pure blue. It causes a small incremental bleed into green with each cycle. Not reproducible under 3750 over over 4750ms.

I'll still have to figure out what causes it.
[Galaxy S 4 i9500 Original Android Development] jlevy73:
The app does not have timing settings, just color settings by hex. I have tried a range of delays but still get the odd blue then fade out to green.

Yes, I can reproduce based on setting STweaks per above.
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
I found out the issue.

Small mistake with relatively big consequence. This should fix all issues I'm aware of. Version 6.1.

catching up with the latest developments here , jus flashed aplpha5 and noted the stock voltage for 200mhz (A7 cores) went up from 900mv to 950 mv, is this based on the efficiency of the chip or is it deliberate?
[Galaxy S 4 i9500 Original Android Development] croach246:
Thought I'd give an update. Flashed omega v10, earlier tonight, and just flashed 6.1 over alpha5. No obvious issues with any combination. Currently on omega v10,alpha6.1 with nova launcher and the thing is super smooth. Haven't messed with voltages yet.

Am looking into Crossbreed.. But know little about it. If anyone could give it a thumbs up or a "not worth it" that'd b great.

Enroute to the airport, just flashed CWM 6.1, still says alpha6 under kernel version btw. Still getting the "fade out as solid red" when using purple / violet type colors. For reference, solid red is FFFF0000.

(I'm gonna be that weird dude playing with his device's LED at the airport lounge.)
[Galaxy S 4 i9500 Original Android Development] alandd86:
We should do this in order to fix this issue??!!
[Galaxy S 4 i9500 Original Android Development] jlevy73:
Which apps in particular are causing you problems? I found that any app that allowed me to alter the LED color via in-app control was an issue on Alpha 6. With Alpha 6.1 that got resolved. You're also using Light Flow, correct? I'm sure you thought of this but why not uninstall that app and see if the issue get's resolved. If you're at the Taipei airport I watch out for that weird due playing around with his LED's lol.

Hi all,

Just trying this kernel, right now my configuration are :

min clock : 200 MHz

max clock : 700 MHz.

A7 Max : 700 MHz.

CPU and GPU underclock at -50mV all.

Trying to figure how much benefit on battery if only using little cores.

I got some questions :

1. With my curent conf, a7 max 700 and max clock 700, means it still using a7 cores with some overclocking rigth ?

2. I see on low clock using same voltage, is it will eat same battery or not ?

3. Anyone using 100MHz as min clock ? Do it get benefit for battery aswell ? Can it make death sleep ?

Im planning to trying it later after my got some result on my current conf.

Many Thanks :)

Don't underclock to 100mhz it will either crash or won't wake up from deep sleep

I was once stable with messing in undervolting etc in stweaks. Why do i have all voltages underclocked at 75 below the default value even when pressing the reset everything to default in stweaks? Also when changing voltage setting my phone is instantly freezing and rebooting.

EDIT : i just fixed the freezing of the device. It was due to A7 cpu frequency at 750000. I just changed that to 700000 (1.4ghz) and its all fine. Still dunno why all voltages are -75uV below the default voltage mentioned. Only the 1.8 mhz step is at default voltage. Do i keep them this way ? Everything is stable and no freezing.
[Galaxy S 4 i9500 Original Android Development] cmd512:
Only using Lightflow, weird part is only certain colors doing this. The blues are working fine.

Now in Shenzhen, all sorts of weirdass LEDs here anyway.

UPDATE: Ok, I can duplicate this bug now as I thought it was custom colors. Choose a notification in Lightflow, apply the preset color "deep orange," and run the LED check. It'll fade in Orange, and turn red (FFFF0000) fading out.

Btw, what version is your kernel showing under about device? Mine still says version 6 even after flashing 6.1 CWM.

Has anyone found a stable voltage for 1.8Ghz? Because my phones default for that step its 1225 but at least geekbench wont run, it shuts my phone off. The one sold in China I think, its clocked at 1.8 stock so we shouldnt have any issues with ours.

[Galaxy S 4 i9500 Original Android Development] mw86:
I have had 100mhz min stable on stock volt for the entire duration of underclock getting implemented to kernel. Only reason it should be crashing is undervolt on it or surrounding idle mhz or forcing a mhz to be used on screen off. Many guides recommend to avoid such profiles.
[Galaxy S 4 i9500 Original Android Development] acidmoder:
I do use screen off CPU profiling and have no issues at all (min 100 / max 250)
[Galaxy S 4 i9500 Original Android Development] mw86:
Then based on that, Croach's issue must be not related to screen off max and should be stable. I'm on the stock for my cpu volt on that mhz which is 950mv for reference. Im glad yours is stable too, hopefully Croach can sort out what is crashing it. Perhaps you use a differed app than that user. I try to use stweaks and scripts wherever possible. Goodluck Croach I hope you get solved.

[Galaxy S 4 i9500 Original Android Development] croach246:
Thanks guys. Based on what you've said I'll have another go at the screen off max cpu. I tried slowly increasing the max mhz when screen off and it would intern shut down less and less frequently.

I'm currently running min cpu = 200MHz @ 900mV. A7 max = 700mhz and max freq. At 700mhz. So far so good.

Can someone explain why in STweaks the "max a7 freq" can be set to 750mhz yet there's voltage settings up to 1500mhz.. :s

---------- Post added at 11:41 PM ---------- Previous post was at 11:29 PM ----------

Depends on what you're trying to achieve really. Over clocking as the term suggests will make you're phone run "faster" and more stable but only up to a certain level before you become unstable or cook your chips - this obviously uses more battery. The opposite is true for undervolting - uses less power, may become unstable (random reboots, freezes etc.) but better on battery.

The i9500 has 8 cores but only uses 4 at a time (4 big cores and 4 small cores). So STweaks let's you mess with the voltages of both small and big cores. When under or over volting, you can safely go +/-50mv (= 50000uV). Guys may report on the upper or lower freq. Steps (200MHz & 1800mhz) +/-50nV may be too much and may cause instability... I haven't had this issue when undervolting. (on my s3 I was undervolting up to - 100mV on some steps)...

So now you have a little knowledge about what the voltages do, start experimenting.. I'd recommend NOT checking "apply voltages on boot" - this means if u screw up a voltage and your phone crashes, it will apply the stock voltages when you reboot and u can go again.
[Galaxy S 4 i9500 Original Android Development] gdonanthony:
i always undervolt to -100mV its stable for me ... no crash or random reboot ...camera also is blazing fast to open and capture
[Galaxy S 4 i9500 Original Android Development] beatsmaster0510:
Seems that my issue with 750mhz freezing the phone upon screen on is somehow fixed using SetCPU. My big core max-min is 1700-200mhz, with -50uv on all cores. The little core is set to 750mhz with default mV then -50uv on the rest. I created 3 profiles on SetCPU, Screen off (250-200mhz), Screen on (450-250mhz) and Screen unlocked (1700-200mhz). I just noticed that the core settings freeze after screen wake in which the CPU freezes when throttling from 200mhz. Creating SetCPU profiles limited the throttle to 450mhz then up 1700mhz for full usability of the two cores.

^

Overclocking the A7s to 750mhz was talked about earlier in this thread (when alpha5 came out I believe) some guys were successful others weren't, think there was a specific voltage it was stable at, just do some digging.

---------- Post added at 04:50 AM ---------- Previous post was at 04:45 AM ----------

Had screen off max cpu set to 200mhz (slightly UV). Stable all afternoon but crashed just now.. I'm wondering if it's not the extended battery - a 5200mAh hyperoin or something.. That's the only thing I've changed since coming to work (I use the big battery when I'm on the midnight shift, get over 8hrs screen time). Does anyone think the battery could be the cause? I will need to do a few days of testing.
