Stratosk, I don't know if you're aware of the issue or not, and this isn't kernel related so I apologise, but changing active CPU governor in Semaphore Manager seems to freeze the app and device for 10 seconds or so

I have high battery drain when using H+. Im on stock rom.

If i flash the old radio will it fix it? Or it wont even work?

Is it the only option that freeze the app?
[Nexus 4 Original Android Development] gorilla p:
It will work and if you have tmobile it can enable Lte. Use link below to flash 27/84 hybrid radio and Lte enabler script. This confirmed works with 4.3 and 4.4

Otherwise download hybrid radio alone from thread in previous post.

Im from Portugal, Europe, we use band 19. So hybrid is useless... The N4 radio only gets band 4

Hey everyone,

I remember I had 1.4.1 running on miui,

But I reinstalled the rom and 1.4.1 gives me bootloop.

Is there anyone who knows how to get it working, or at least knows why it ran back then, but bootloops at the moment?

Thanks in advance

Fresh flash or did you use the ota update?

Edit: nevermind. Works like a dream.

What I did:

Restored the stock kernel with wugs toolkit.

Flashed the ota update with twrp.

Reboot.

Flashed supersu 1.80 and semaphore in twrp and wiped cache and dalvik afterwards.

Don't know if this is the preferred way to do it (I have always been more of a fan of the clean flash procedure). But it seems to work fine

Good evening,

I've used Semaphore with 4.4 and changed the display gamma to get better colors. Some minutes ago I've updated to 4.4.1 (OTA via custom recovery) and without reinstalling Semaphore the colors are perfect.

Is it possible that some Semaphore settings are still active (I've flashed the stock boot.img before updating)? Or did Google manage to fix the colors? :confused::confused::confused:

Use interactive governor..

Increase the up threshold of hotplug driver up to 95, use hi speed freq 1026000 & high speed load 95.... these are the settings that i use . if you're feeling that these settings are not smooth, then lower the up threshold of hotplug. Try it...

I read a couple pages back, that we can fix the battery drain on 3G by flashing an older radio? Is this true? Which radio should I flash? (My country doesn't support Nexus 4 4G, so I don't need 4g)

Also should I clear battery stats after flashing a new kernel?

Thanks!
[Nexus 4 Original Android Development] Dan1234567890:
Every radio is dirrefent, as well as every phone has different usage of the radio. There has been reports that some versions are better for the battery/reception on lower signals, some are better on higher signals for data speed, l some are better for 2g, some has 4g capabilities, and so on... And all this is connected with battery consumption, as well.

But all this questions should be answered on radio/modem thread, which you can follow here: http://xdaforums.com/showthread.php?t=2087227

There is no need to clear battery stats after flashing kernel. :thumbup:

Is there anyone who knows which files are stored/changed by Semaphore, that are not reverted by flashing the stock boot.img or a different kernel?
[Nexus 4 Original Android Development] stratosk:
None.

Semaphore doesn't change any stock file.
[Nexus 4 Original Android Development] rogers11:
Ok, thanks for your answer. In this case stock 4.4.1 does have much better colors on my device than stock 4.4. I was unsure if this may be because of some leftover gamma-settings.
[Nexus 4 Original Android Development] Skkip:
Except for init files (init.rc / init.mako.rc)?
[Nexus 4 Original Android Development] stratosk:
These files exist in initramfs (in boot partition). If you flash back stock kernel, you will also get back stock initramfs and init.rc, init.mako.rc.

I have seen flickering issue with all CM/its derivative roms. That was actually very often flickering. Then I switched back to stock rom with stock kernel. Flickering never happened.

Hi [MENTION=3750240]stratosk[/MENTION],

I would like to ask you about improvements on Semaphore kernel. We don't see much updates except upstream and google commits for last a few version. Please don't misunderstand me because I am really satisfied with current Semaphore kernel. I am using it on my N4. Also thinks that it is the best kernel in production for N4. Anyway, will we see you again with new features, optimizations, patches from other newer kernel versions? Hopefully there are still some room for improvements on it.

Thanks in advance,
[Nexus 4 Original Android Development] stratosk:
Hi,

Always, there is room for improvements. This is my goal and I always hope for something better (though I believe that Semaphore is in a good shape now).

My problem is that my free time is very limited during last months.

Semaphore project is my hobby and I try to work on it usually late at night, after a really long day (due to my real job and my family).

It's not easy and I can't be always creative.

Believe me, I try to keep Semaphore project alive (many times I think that I have to stop it and find a second job for extra income).

Anyway, I'll do my best. :)
[Nexus 4 Original Android Development] torstenconrad:
Stratosk, you have a loot of fans and followers on XDA. But the family at home is always #1, remember they depend on you to be there. If a forum comes inbetween, I am sure we all can understand. I hope you chose to do what is best for yourself and not the forum. I think we all wish you the best and truth is, you have already done more than anyone could ask of.

Take care!
[Nexus 4 Original Android Development] stratosk:
Thank you, my friend, for your words! They really mean much to me.

We very much appreciate the amount of time you spend on the project. I wish I could make some monetary contributions as well, unfortunately I'm still studying, once I'm done and get a job I'll make sure to do so.

[Nexus 4 Original Android Development] skunks11111:
Okay so there's some misunderstanding here. The TouchWake function in semaphore only works when your phone turns the screen off after some inactivity. That's cool but the Sweep2wake function that I want is enabled all the time. You turn your screen off and can also use sweep2wake. Just like in the earlier Franco Kernels and now in Matrix 11.5 which is what I am using. It lets you turn the screen on faster and with the phone lying on the table. By saying Touch Control I ment this app here:

https://play.google.com/store/apps/details?id=me.paranoid.touchcontrolfree

Even though Matrix isn't compatible with the app, I can still enable DoubleTap2wake in Trickster MOD.

As I've said, I'm using Matrix 11.5 now because of this feature so there's no need to implement it(except you want me back;P)

Thanks!

Hi

Just to know if this only stock issue or it also happens in semaphore. No matter how many apps I open, my fully stock 4.4.1 nexus 4, has always 52-50-48% free RAM (seen with ram usage app and memory booster app).

This per se is no problem. The problem comes when it has to kill heavy apps to keep this almost 1Gb free and have a constant reload of apps that could be permanently un RAM.

If someone can tell me if I would avoid this annoying problem with this kernel, I'd really apreciate it. Or at least a reason why this RAM is unused, if there is one.

I googled a lot finding several similar questions but no answer at all.

Thanks a lot!

PS: A friend of mine has a fully stock nexus 5 and has seen with memory booster a 28% free ram! So this is not a generic android OS or kitkat problem but a nexus 4 specific...

Did u already thought that maybe the nexus 4 uses that 1gb for cache?

sent from my NEXUS 4 tasting KitKat for the first time
[Nexus 4 Original Android Development] CalabiYau:
I don't think so. Adding services AND cache gives below 1 Gb. I've seen this in the native app/memory tab, adding 'manually' both services and cache (always <1Gb).

Also several tools like memory booster consider the total usage, including cache file and consistenly give values over 48% free RAM.

And if apps stayed at cache they wouldn't completely reload as they actually do.

Finally, nexus 5 with the same OS 4.4.1 and same amount of RAM (2GB) do use more RAM. No cache reserved then?
[Nexus 4 Original Android Development] C4SCA:
The nexus 4 has 533mhz ram aka ddr2 and the nexus 5 has ddr3 (1026mhz), if I'm not mistaken. Maybe the difference is there, anyway both have to have a cache part on the ram.

Personally i doubt have those reloads unless on chrome. I can even play RR3 and go back to Facebook and it doesn't reload. I'm stock 4.4

sent from my NEXUS 4 tasting KitKat for the first time

---------- Post added at 10:28 AM ---------- Previous post was at 10:27 AM ----------

Those reloads u talk about, are they faster than opening the app? (If it's closed)

sent from my NEXUS 4 tasting KitKat for the first time
[Nexus 4 Original Android Development] CalabiYau:
No. It takes the same as in a fresh start.

For example gmail takes one second the first time you open it. After some time without using it or openning other heavy apps, if it happens to be killed by the memory management, it takes again 1 second.

If it is in cache is almost instantaneous.

In my case, if I open maps, dialer, hangouts, chrome, firefox, i.e heavy apps, then I see that it starts to reload some of them with this 50% free RAM.

If they were in cache, hardwired or sw cache, then I wouldn't have noticed a reload.

I just want to use this post to say thanks to stratosk :). My phone stayed at 82% for 3,5 hrs with some SOT (~10 min I guess). I thought it was Android's lame battery reporting and my phone was gonna drop straight to 78 or something. To my surprise, it dropped to 81, which means the battery life's actually so good thanks to semaphore kernel. The signal reception here isn't good, my phone occasionally drops 3G to use 2G. Also I haven't experienced battery life this good since updating to 4.3, even with some other popular kernels.

Semaphore + purity is awesome :).

QUOTE=gorilla p;48184928]Semaphore manager or Trickster Mod apps.

I understand that. And for those that are used to using it, in sure they can just waltz through it. Those that are new to messing with kernels and such would have a clue where to find some of the settings some of you mention. Both Semaphore and Trickster have more than one screen. Also, entering some of the settings isn't intuitive (gamma settings for instance). That's the point of my post.
[Nexus 4 Original Android Development] nithin1992:
Alright just bookmark this post or something if you need it again, its all your gonna need.

The color temperature is almost always 255,255,255 so don't mess with that. You have to save 9 values for each red green and blue in the gamma control with a space between each value[not necessary at the start and the end].

Example:
Red:0 39 119 1 6 0 2 0 1
Blue:0 39 119 1 6 0 2 0 1
Green:0 39 119 1 6 0 2 0 1

The terminology for above array's positions are:

greys mids black 1 contrast brightness saturation white 1

The positions 4 and 9 are hardcoded values, leave them untouched with 1. Download the file, find whichever color profile you'd want and replace the greys,mids,black etc with the corresponding values of the color profile. Turn screen/off and you'll find the new colors.
