[Q] GPS-problem with mathkid's matrix kernel 9.0 - Nexus 4 Q&A, Help & Troubleshooting

Hi,
In know this doesn't belong here, but since I haven't posted yet, I'm not allowed to write in the corresponding thread.
I installed matr1x kernel 9.0 on my n4 yesterday and got massive problems with GPS. The GPS-location needs VERY long to settle if is working at all. I had the best conditions for GPS since i was walking outside in pretty open space with a clear blue sky....
Anyone got the same problems or any ideas what could be wrong, since i found nothing on this topic according to the matr1x kernels anywhere.
Okay. 9.0 is new, but someone must have noticed it if it is a general problem with the kernel.
the power-management is astonishing and I would gladly keep the kernel for that.
regards...

Although I have only used the kernel for a couple of hours I've found the GPS to be spot on and very quick. Some have said changing the location in your build.prop to your correct country helps?
System>build.prop

thanks. I'll give it a try if the problem reoccures. For now i just reflashed the kernel and everything works fine again. maybe TouchWake was the problem since that was the only thing i changed since flashing yesterday. I will try again and see if the gps-break reoccurres.

Bugs in stock phone

I am assuming once you root the phone and push a custom ROM onto the phone, this will fix HTC's introduced bugs?
Bluetooth
SMS battery drain
Reverting apps versions
Stuff like this.
No, because the custom ROM is just the Sprint ROM with a few additions and modifications.
Ouch.
ok, anyone working on compiling a 2.0 kernal?

Although the bugs are not fixed, rooting allow one to use various workarounds that would not be possible without, and in fact for EACH of the issues you have listed:
Bluetooth: http://community.sprint.com/baw/thread/23854?tstart=0
While I cannot personally vouge for this, I have seen many posts on Sprint and here that detail the workaround described in the post as effective.
SMS Battery Drain: I think this may have actually been the first big bug discovered, and also fixed without root! Unfortunately, the default messaging app is defective, so in the meantime it is recommended to use either chompSMS or Handcent SMS from the Market until an update is released.
See this post: http://community.sprint.com/baw/thread/23043
Finally...
Reverting Apps: This is addressed on both forums, but a workaround only exists with root, and is similar in fashion to the bluetooth fix but for a different directory.

Hope this helps! I intend on posting a very detailed guide on every step of rooting, backing up, and working around most of the detailed problems in the very near future, stay tuned!
What I'd like is a kernel that will have this working as intended. But really, I am not afraid of the work arounds and the hands on work required, but if my wife had this phone with these problems, she would have chucked it out the window within days.
One more...
You left out the original bug (mentioned by briankwest, one of the first rooters), the TCP timestamp issue:
echo 0 > /proc/sys/net/ipv4/tcp_timestamps
This could also be added to the MoDaCo init.rc so it is set at each boot (otherwise it will revert back to "1").

Screencast black screen?

Hi guys
I use screen cast a lot on my n4. And it worked fine. But on Friday I restored my stock backup and then did the ota to 4.2.2. Then I flashed the latest faux kernel beta.
This morning, I wanted to use screen cast so I started it, created my video for like 5 mins. When it saved, I watched it but it was just a black screen! You can still hear my voice though. I ticked these two settings in developer settings (in attached screeny) as it said to do on the gplay page but still no luck!
BTW, I was using PA 3.0 beforehand.
Any help? Any suggestions on what I can do?
Cheers

Anyone?
Same problem here with an AOKP Unofficial 4.2.2. Reflashed back to AOKP MR1 Build 3 (4.2.1) and it works again. So it looks like this is being caused by 4.2.2.
Well i got this fixed by going back to Paranoid Android (4.2.2) so i dont know whats causing it.

Strange. I experience the same problem on Paranoid Android 3.1
Despite writing to the Developers, they won't fix it or even acknowledge.
this is a shame, i wanted to stay on stock, but i will try to flash paranoid to see if i manage to get screencast to work.!
Screencast was found working on Slimbean. But not any other mainstream custom/stock 4.2.2 ROMs. Such a shame.
I don't think the developer of the App is to blame for this. This looks like a framework change in Android.
So any devs know why it broke?
Still not working? I get black screen while recording on my S4 ATT 4.2.2.
Any Solutions??? or ALTERNATIVE

Battery drain problem

Hi guys, as I wrote in the title I have a really awful battery life with my Nexus 4 and I don't think it is related to the rom/kernel I'm using because lots of people with the same configuration have no problem. I'm currently using PA 3.99 RC2 with Semaphore kernel, but I've tried also franco and I have the same result. I started from stock rom and then i did a full wipe before installing PA, but I keep having problems. This is my situation:

}

I'm unable to post a log because the apps don't show it to me (I can't understand why) but it seems like the problem is related to the app I use, anyway these are very popular apps and I find absurd that to have a decent battery life I have to uninstall them because in this case I would only use the phone to call and send texts, many people are using these apps and they have a great battery life so I can't understand.
which recovery are u using? u need maybe to update it or try another recovery. I had problems with some roms, after switching to another recovery everything was fine.
maybe u give it a try:good:

I'm using TWRP, it seems strange but i'll try with CWM!
Try detecting what's using resources and keeping the device woken up with WakeLockDetector.
@mods: can't we just sticky the Battery Impressions Thread adding a 'post your battery issues here' to it's title? We're getting overloaded with battery drain threads, and the issues are common enough to have them a sticky. Thx.

I used it, in fact I posted a screen with the result and it seems that google+, facebook messenger and whatsapp are causing the issue but this apps are used by many people and they don't have problems, it just doesn't make any sense to uninstall these because I mostly use the phone for these apps :s

Wrong Kernel Showing on Pardus HDC 7.7

And here's the Screenshot from the HDC Thread:
I also flashed the latest Kernel from dorimanx's website:
Code:
dorimanx.com/LG/
But it just doesn't change. I don't know whats wrong can someone help me? and i see a severe battery drain from every 5min it really drops a 1 percent.

They're just showing the extended kernel info. If you have the st tweaks app, then your on dorimanx.

These roms also have location set to high accuracy by default. That's a huge drainer. Roms also need a bit of time to settle after you flash them before they start to perform more efficiently and finally dorimanx is not the most economic kernel on its default settings imho. Try bruce or simple kernel if your not into tweaking it.

[DEVELOPMENT] Android 5.1 discussion

Hey guys,
we all use and work on different ROMs, be it OmniROM, CyanogenMod or AOSPA. However we all use very similar (if not the same) device trees and for that reason, I have decided to create this thread. Anyone can post test builds, logs, experiences, commits or whatever here without having to clutter other threads or open new ones.
My kernel should be good to go (it is pretty much up to date with the latest CAF upstream of the A-family, which means none of the kernel commits on cm gerrit (android_kernel_sony_apq8064) are required.) I'll be pushing everything I commit here: android_kernel_sony_apq8064.
Looking forward to a successful/effective collaboration guys.
Sounds good to me
Gave SlimLP a go - it boots. Although I didn't test it for long, I did notice that RIL is broken. Everything else should be working. I've used the kernel mentioned in the OP to get it compiled. I'll probably continue working on this on the next weekend.

Yeah RIL is broken due to old sepolicies, I haven't had a chance to update them for Lollipop yet. Should be pretty easy though, using either pabx's policies or mako's for reference.

Yea me neither, I just went for permissive SELinux and disabled our policies (in fusion3-common) as they were breaking the build. We'll see...
I have updated the kernel to LA.AF.1.1-01310-8064.0. More CAF upstream coming soon...
Bump (and this goes to everyone using any 5.1 ROM) - just out of curiosity; what kind of random reboots do you guys experience? Hard reboots? Soft reboots? Or something else?
Describe the issues as precise as possible and upload logcat, dmesg and last_kmsg (and mention what ROM build you use)
I use pabx lollipop 5.1 aosp as daily driver.
Absolutely great working rom, no issues, no reboots no freezes. I feel like i have a nexus
Guys the reboot issue has been solved for me after update and it only happened when phone was in charge any idea why I have a lot apps crashing specially on Google chrome
