[Nexus 4 Original Android Development] wietse1988:
Where you comming from franco allready? Did you reflash the rom or a reset kernel before flashing matrix kernel? If not, trie to reflash the rom or a reset kernel, and then Matrix, then there should be no problems.

Dunno if its just me but, whenever I try the matr1x kernel my camera gives a strange matrix like pattern. As if its reflecting the back pattern off the phone. Only does it when the flash is off as well. Its fine on Franco or stock. Anyone else had this issue? Apologies if its already been stated
[Nexus 4 Original Android Development] Aztriltus:
I get that if I under volt my phone too much. Maybe you could try bumping up your voltage across all the CPU frequencies.
[Nexus 4 Original Android Development] omer7:
On how much UV u get such pattern in camera?

Just flashed the kernel, looks interesting. Since this kernel doesn't have Prima drivers (yet, or may be no plan), how are you guys dealing with delayed notification over wifi?
[Nexus 4 Original Android Development] mixtapes08:
:) awesome kernel. It's so smooth. :P

-3StarsAndaSun
[Nexus 4 Original Android Development] omer7:
The delayed notification exists on stock kernel as well? Right?

And what r prima drivers btw? :(
[Nexus 4 Original Android Development] nileshgr:
Delayed notification is a bug in the WiFi driver supplied with the stock kernel. Many kernels including this using that driver. I know only Air Kernel which uses the updated Prima drivers which doesn't have the delayed notification issue.
[Nexus 4 Original Android Development] Rampage Trav:
Thanks mate, I only use the default settings so unless its under volted by default but I assumed that's where the reported battery improvements were from, the UV.
[Nexus 4 Original Android Development] sigma392:
+1 for a Prima Edition of this kernel. I'll gladly accept it even without support (Since Prima is experimental after all).
[Nexus 4 Original Android Development] reicute789:
yes i came from franco m3 before flaahing matrix. where can i find reset kernel? thanks
[Nexus 4 Original Android Development] nileshgr:
Flashing ROM + gapps + any extra things like Emoji keyboard (if you use) and finally kernel should help. That's what I did when WiFi refused to work after flashing. Was using Air Kernel earlier. But better wait for a response from someone who has done it.
[Nexus 4 Original Android Development] AsesinoQc:
UVed by 100 (default)
[Nexus 4 Original Android Development] wietse1988:
Just reflash Rom + Gapps, without a full wipe, and then flash Matrix you should be fine, before you do that make a backup so you could always restore if something goes wrong ;)

Hit thanks if I helped you :)
[Nexus 4 Original Android Development] reicute789:
thanks mates. so far so good. :D
[Nexus 4 Original Android Development] nileshgr:
This kernel has magical WiFi drivers. It doesn't seem to have the delayed notification bug (or more precisely, losing connection on deep sleep) even with the default stock WiFi driver.

Brilliant!

how to flash this kernel? just put it on sd card, go to recovery and flash it from there?

do i need to do some wipe?

tnx
[Nexus 4 Original Android Development] PetritH:
Depends on rom u are using, if u are using cm based roms download the cm one.. if u are using other roms download the non cm one... oc-ed one has simple gpu governor, you can try that works nice

Wipe is not needed when flashing kernels bro, download go to recovery mode and install then reboot,thats it

Non oc version has simple governor too! Also i would advise to unexperienced users to flash non oc version.

Or use the kernel cleaning script from http://xdaforums.com/showthread.php?t=2121701.

Be sure to choose the right version of the script else you will format your memory as well.
[Nexus 4 Original Android Development] omer7:
Why the gpu usage in my phone most of the tines remain at 400MHz, though i m not even playing a game. Is it normal?

I m on CM stable with cm non oc kernel.
[Nexus 4 Original Android Development] sirxdroid:
I noticed the same thing, the GPU spends a lot of time at 400. It can probably be made less aggressive by changing the value for simple_laziness to something like 2 or 3, under the GPU Governor Control. And/or reducing the max freq to 325 if you think you don't need the full 400 power.
[Nexus 4 Original Android Development] omer7:
Thanks for the reply. 400MHz is fine, dont want to reduce the value. But i was wondering why does it stay at 400 for most of the times. Anyway it seems it is because of values. I m on free trickstermod so cant check or change the values of gpu governor.
[Nexus 4 Original Android Development] sirxdroid:
You can do it from the command line, something like:

echo 3 > /sys/module/msm_kgsl_core/parameters/simple_laziness

The other one is simple_ramp_threshold, you can bump it up to not ramp up quickly, meaning less aggressive.

Note that you'd have to put these in an init.d script if you want them to be applied at boot, otherwise they would get lost when you reboot your phone.

[Nexus 4 Original Android Development] sirxdroid:
Why can't you? Run BBS and see what's keeping your phone awake. If you make a lot of phone calls then it will be hard to get those numbers, but otherwise it should be achievable, in particular on wifi. For example I'm at 27 hrs on battery and 2h 12min screen on (most of it on wifi, with just some short phone calls) and the battery is at 52%. I should be able to hit 2 days and 4 hrs screen on with the same usage pattern. I use EOS + Matrix v10. This is the first time I'm giving Matrix a serious chance :)
[Nexus 4 Original Android Development] Galaxo60:
The best I have done is 3hrs screen time and around 20hrs without a charge, but never been in this kernel, so I will give a try. By the way, I read that EOS died, and now is merging everything to CodeFireX.

Flash this kernel just like old time when using nexus s..

[Nexus 4 Original Android Development] Aashrey99:
Hey guys, I'm back on Matr1x 10 after trying out the STS kernel.

Anyways, I've started getting bad battery life, consistently, across all ROMs/Kernels. When I got my Nexus 4, I stayed on stock for almost 3 weeks. I was getting pretty decent battery life (20+ hours, 3+ SOT) and then i started flashing ROMs just to check which ones I liked and find my daily driver. I must have flashed about 5 ROMs, one per day. Now my battery life is terrible (barely 14 hours, 2+ SOT), even when I revert back to stock it's not as good as the original stats I was getting.

So, is this a case of the crack flashers battery syndrome or just plain dumb luck or is my battery bad? I have no idea. Any suggestions to remedy this would be greatly appreciated. I'm running CM 10.1 with Matr1x 10 (regardless of what my sig says, haven't updated it yet).

PS: I don't have any wakelock issues. I use greenify but only on Facebook, I use Google services so I don't greenify any Google stuff.

Getting some amazing battery life on v10

[Nexus 4 Original Android Development] Galaxo60:
I have to say is not impossible to get these results, with processor capped, the additional undervolt, WiFi all the time and brightness at 10% it is easy to reach moreover the same results. It is more than clear in the screenshot that all the time he was on Wifi.

The strange thing here is that he has a lot of screen time, but almost no usage in other apps, like if he just had the screen turned on all the time without doing anything. If he was using browser and feedly on that almost 8:30 hours, those apps wouldn´t be just at 2%, they should be at least 15% each one. Besides that there are no calls registered on the battery graph.

Just my thoughts, not trying to say is not possible, but this just look suspicious to me...

video record loud environment

anyone?
[Nexus 4 Original Android Development] Galaxo60:
As far as I know there is no fix for this, I have been looking to this for months. The only device I know that has a dynamic sensibility for mic is the iPhone. I went with friend to concert, and my recordings were in really nice video quality, but the sound was horrible. His recordings were nice and the sound was clear.

I have seen many apps to control the volume output really well, but no app to control the input and the recording levels.

I don´t know if it is just a software issue, or some sensors, special mic, or another thing is involved to get a clear sound when there is a lot of noise.

[Nexus 4 Original Android Development] Tusnal:
Sgs can do it, I think is just the sound driver, must be a kernel feature

OK, do this. Wipe data/Factory reset, wipe system, flash ROM, flash gapps, flash matr1x kernel, reboot. Sync your stuff, let it settle down 5-10min. Dont install Facebook app(or messenger), turn off NFC and Google now (if you can live without it). Install (restore) apps you use. Setup the phone settings you like, empty battery until your phone dies, plug in charger and turn on your phone, let it charge fully. Unplug charger. Next time put your phone on charger when your battery hits 20 or 15%. Thats it. Dont know what else to recommend other than flash a fully stable ROM like purity.

Amazing battery life!!!

I am not an extremely heavy user, so I really value the ability to sip battery during idle.

I'm running Matrix 9.5 along with AOKP Milestone 1. This is my first ROM and Kernel for the Nexus and I spent a lot of time looking for the best one for me before I took the plunge. I am very glad I did. I wanted to try Franco and Faux kernel, but I figured I'd see how I like Matrix first since it also included the screen color fixes I wanted. I must say I don't see a reason to try anything else. Performance is very smooth and battery life is outstanding.
[Nexus 4 Original Android Development] dunni88:
I guess one follow-up that I have been wondering: which do people prefer? Ondemand or wheatley? Or something else? I've seen a lot of people saying they love wheatley.

I'm using wheatley and it seems like it's either at 192 or 1512 (and a ton of deep sleep). Is the theory here that you peg it in order to get something done quickly and then minimize it?

I also saw someone say that Mathkid tweaked ondemand to be really good. Is that true? Is it better than wheatley?
[Nexus 4 Original Android Development] sirxdroid:
How about interactive with the latest patches? It used to be that ondemand was better than interactive at least on the N4, but lately interactive seems to be doing very well and it's very battery friendly. Not sure whether Matr1x has picked up all the latest patches for it though.
[Nexus 4 Original Android Development] Aashrey99:
OK guys, I'm having a very peculiar problem with my phone now. I've just settled on a ROM after a series of flashes over the last week. I just completed my second recharge cycle.

So this is what happens, I charge to 100%, then reboot into TWRP recovery, it shows my charge level to be 82%. I boot back into the system, and charge level there too is 82%. I charge to 100 again and then boot back into recovery and my charge level now reads 85% and so on. Any ideas? I think my system is not reading the battery levels properly. Could I possibly calibrate the readings to match the true battery value somehow?

EDIT: After leaving it to charge for 2 minutes while still in recovery, my charge level reads 99%. Weird..... :/
[Nexus 4 Original Android Development] ctfrommn:
You could go in and delete the battery stats file....although that should be getting overwritten each time you charge to 90+%.
[Nexus 4 Original Android Development] Aashrey99:
Yup that fixed it. Recovery and system read the same values now.

That is definitely an undervolting issue. Raise voltages by 100 across the board, which is stock, and then slowly decrease them if you want to get lower voltages and therefore lower heat. You can keep the lowest CPU speed at whatever you want, that shouldn't give you any camera problems. :)
