Custom ROM breaking serious GPS bug. Help needed. - LG Optimus 4X HD

My Original Post:
Phone runs hot. No deep sleep. High cpu usage from AndroidSystem app. Sometimes screen doesn't turn off after pressing power button. Phone runs slow.
All of this happen after any GPS data request from any app that can use device only gps data.
When GPS is off with a fresh boot, there is no problem.
When gps is turned on but not any data requested from it, there is no problem.
If you turn on device only gps and start using a gps app. CPU usage goes abnormally high and never falls down even after force closing the gps app and gps itself. Only a reboot turns the phone to normal.
Another thread I've found describing the same problem without solution:

I've tried listed roms and kernels with required wipe operations switching between them.
I've rebooted several times after installation and didn't give up in first boot.
I have CWM Official v6.0.4.5 as recovery.
Tried different governors and schedulers. No luck.
I'm using the phone with CM 10.1.3 Stable & WWJB_v009_anykernel-20140429 and I don't have this problem with it.
GPS apps never use high amount of CPU and when you turn off GPS apps, CPU usage falls to idle levels.
I've flashed same WWJB_v009_anykernel-20140429 kernel over a fresh CM11 M10 install and gps bug is still there.
I think this is not about kernel or rom but something different. I can't move forward from Jellybean.
Any idea what's causing this?
Any clues, ideas or suggestions are appreciated.

Update: I still have this annoying problem and I'm trying to solve this.
I need you to test this on your devices and tell me the result. Please.
How to reproduce the bug
1- Prepare your SD card with the custom Rom(Kitkat or later preferably with built-in file manager to install apks) to flash and apk files of F-Droid Satstat, CPU-Z for monitoring the cpu load.
2- Before flashing the rom, REMOVE your SIM card. The important thing is, do not let the phone go online after the fist boot. I will download the Agps data immediately and it may work without problem.
3- Flash X-cm12_1_1-20161131-ufoFILES-p880 or any other Rom which is 4.4+ or later. I've tried many and all of them have this problem.
4- After the first boot,(ignore the no "sim card inserted restart" notification just touch some where out of that box) install satstat and cpu-z.
5- Turn on your GPS if it is off.
6- Launch the GPS test app satstat. It will try to connect to GPS and Glonass satellites (if you have a v20 baseband) It is not important to keep the app running until you get a lock just wait for 15 seconds.
7- Close the gps app.
8- At this point you should be seeing a serious lag. Pushing the power button won't response. The phone won't go the sleep. If it does, it won't wake up easily. You will be pushing the power button several times to make it work. Battery will be drained fast.
7- Launch the CPUZ and watch the CPU load and frequency. One or two cores will spike up and down constantly and the cpu will stay at 1000-1500mhz forever.
8- There is nothing to do but restarting the phone. Sometimes my phone gets totally frozen before I'm able to restart it from the power menu. After the restart it will work normally. Provided if you keep the gps closed and not requesting info from it.
Could you test this please?

Problem solved. Temporary solution.
My description from CM11 Official thread:
Finally, I'm happy to clarify that both assisted and device only gps is working excellent!
After many sleepless nights, I've found what's causing the problem in my device. I've gone over 15+ custom roms and different kernels. I've changed baseband and custom recovery to only get despair.
The last thing I did before abandoning everything.... has worked.
Assisted GPS has to go on-line at least one time.
I'm not sure about the logic behind this but I can't believe how such a simple thing caused this trouble for me...
I don't have a data plan right now so no there is no data from cellular. I generally use device only gps outside. I've never used this rom with assisted gps when outside. I didn't get a chance.
When at home, I flashed roms with "device-only gps" testing in mind so I didn't bother connecting to wireless.
I tried this just with 20150524 and nothing else. (gapps, kernel etc.)
Enabled high accuracy mode on gps and connected to wifi.
Launched GPS Status & Toolbox app and at first, cpu usage was high but after the first fix, it's reduced to normal. I exited the app and cpu usage fell to idle as it should.
Switched off wireless and switched gps to device-only. Rebooted. Launched the GPS Status & Toolbox again and now it's working normally under device only mode. Other applications also working good.
Click to expand...

Fused Location Provider, responsible for managing different data sources for providing geolocation data, manages the assisted or device-only gps itself. When you enable GPS, it switches the gps mode to high accuracy itself but if you hadn't gone online before with using assisted gps, gps is always stuck at device-only. I think that creates the high CPU usage.

THANK YOU THANK YOU THANK YOU!!!! I wanted to change custom ROM because of this, and you saved me from doing it! So, if I understood correctly, all I need is to enable High accuracy mode, launch "GPS status & toolbox" app (or can it be any other gps app?) and restart after the app gets a fix?

You need to let the device to download A-GPS data from internet. GPS status & toolbox does this easily and you can see the "a-gps age" at the app screen as how old your data is.
Once you get a fresh a-gps data, the phone won't stuck at high cpu frequency when gps is enabled.
I 've found out that after "a-gps age" goes over 20+ days, something happens to the gps, and gps usage starts to cause high cpu usage and frequency stuck again. You have to re-download a-gps data to solve this.
I don't know why but gps in this device is not a true offline gps.

I've already described a temporary solution to my GPS bug.
I'm still trying to find a lasting solution.

Nothing works for me so far.
Thanks to @oF2pks , I think this may be ril/baseband problem.
Here is another thing:
When I check the "Settings/AboutPhone baseband" it shows L6260_modem_sic_02.1233.00 but If I disable SIM PIN lock and restart the phone it shows LGP880AT-00-V20C-EUR-XXX-OCT-07-2014.
According to oF2pks, a healthy phone should always have only one baseband reading under Settings/AboutPhone baseband.

Sorry for the late answer. I didn't give up and still working on my issue.
For easy describing, lets say State X to the the high cpu state which is causing general slowdown, stuttering, lag and freezes for my device, which occurs after GPS usage, without any data connection after fresh rom install and that kicks in again any time if you are not online with the phone frequently.
After many flashes and tests I found some interesting things.
- In State X, the phone actually goes to deep sleep BUT you have to wait for the 1 minute screen timer and don't push the power button to send it to sleep. After waking it up, cpu is still stuck.
- p880-ota-eng.nmf26qz never displays L6260_modem_sic_02.1233.00 but still falling to the State X.
Only custom rom working without State X problem for me is the cm-10.1.3-p880 stable.
I tried:
Switching cm-11-20160815-NIGHTLY-p880's com.android.location.provider.jar with cm-10.1.3-p880 stable's. → Result: State X
Switching cm-11-20160815-NIGHTLY-p880's telephony-common.jar with cm-10.1.3-p880 stable's. → Result: Error at start-up
add line to getprop file: ro.ril.def.agps.mode = 0
→ Result: State X
Switching cm-11-20160815-NIGHTLY-p880's lge-ril.so with cm-10.1.3-p880 stable's. → Result: State X

So do you have right baseband v20C when you boot with sim-on, or still firmware number?
Click to expand...
Click to collapse
This is where the things are getting interesting...
- With CM10.1.3-stable, first boot after the rom flash(without sim card) baseband shows L6260_modem_sic_02.1233.00 but in the second boot with sim card, after the very first initialization with gsm tower, it shows LGP880AT-00-V20c-EUR-XXX-OCT-07-2014 and stays like this.
- With my current daily drive cm-11-20160424-NIGHTLY-p880 + WerewolfJB kernel V10
Without sim-> LGP880AT-00-V20c-EUR-XXX-OCT-07-2014
With sim-> LGP880AT-00-V20c-EUR-XXX-OCT-07-2014
Sim with sim pin lock-> L6260_modem_sic_02.1233.00
With different roms, sometimes baseband switches from LGP880AT-00-V20c-EUR-XXX-OCT-07-2014 to L6260_modem_sic_02.1233.00 after gsm initialization.
In one situation, after all the tampering, I flashed CM10.1.3-stable again and this time it was stuck with
L6260_modem_sic_02.1233.00 and never showed the LGP880AT-00-V20c-EUR-XXX-OCT-07-2014 but no State X
With my daily drive, I also checked both states with sibor's Getril. md5sums are the same.
I'm adding screenshots for them.
I think, maybe baseband display is irrelevant with my issue.
Also did format via recovery cleared your previous rom specific settings?

All settings clear but I'm not sure abut default gps switch behaviour. Maybe it's irrelevant too.
Somehow gps switch remembers it's old positions.
Today on single(/primary_multirom) rom I have same kdz designation v20D while booting airplane or sim-on.
But on 2nd/multirom I have the difference (due to primary fake transition via kexec ?), AND the gps is working fine : airplane boot (+FasterGps) + Satstat OK and deep sleep after OK.
Click to expand...

My current daily drive does not have the State X rgiht now. It will stay like this for a while without internet connection, but after some time, something will trigger the State X again and there are two solutions:
1- Don't enable GPS
2- Connect to internet and update the A-GPS data.
Did you check CPU usage after GPS use?
Mine stays at 1000-1400mhz with one or two cores.
IMHO you should pm @Demetris about V20C because he was the one who did cover v20c-2014 :http://forum.xda-developers.com/show...postcount=2727 ; also he's OP for alternative http://forum.xda-developers.com/opti...grade-t2919195 (and many more...)
Click to expand...
Click to collapse
I did the CSE flash method of Demetris for the V20C 2014.
I'll ask him about this gps issue. Thanks for the suggestion.
I'm also adding my getprop result for you. From fresh CM10.1.3 stable.
The biggest deal breaker for me with this phone was the "temp_throttle_skin" (around 40°C) temp limit. It's a real pain to have and the main reason of general slowdown.
At least I can deal with this GPS issue from time to time when it needs correction.
My aim here is to create some consciousness about this elusive issue for the fellow O4X users, so some unexplained battery drain issues may be resolved or dealt with by the user.
I wish everyone a Merry Xmas and a happy new year.

@KSH2014 , can you check few more:
-is imei/software = printed imei under battery
-is GPS OK with cm10's original kernel
-is GPS OK with lg JB v20c
Within hidden menu in lg JB, I remember bunch of options (GPS ?), and you problem could be somewhere in it, maybe @RuedasLocas could help you to re-settle this hidden menu

- GPS is OK with CM 10.1.3 Stable release with it's own kernel.
- GPS was OK or I think so with JB V20. I have to check it again.
I'm planning to record and upload a video to show the problem.

[ROM Feedback] CM 6.0.2 (09/05/10)

To my knowledge, there is no thread dedicated to the new numerical releases of CM. Let us start with the newest, CM 6.0.2.
Please post your anecdotal data, including benchmarking scores, bugs, and glowing experiences. Perhaps this will serve as an unofficial repository for issues that prove consistent.
Note: After modifying my WiFi settings, specifically disabling sleep mode while the screen is off, I've encountered no related instability.
Mail FC Fix: http://forum.xda-developers.com/attachment.php?attachmentid=394316&d=1283500340
Systemic issues yet to be addressed:
-LEDs do not work save for charging
-Outgoing calls initially drop before reconnecting
-Lockups or reboots, likely stemming from SetCPU
-OS does not recognize internal storage
Does this version fix the wifi not staying on?
Did you change your settings to Never sleep for wifi and just left the wifi on? Thanks...I want to try different settings and see if I can eliminate reboots/shut downs.
are we waiting for the nightly for the newest fixes like LEDs or is there gonna be a new release like .3?
OP you are a month behind (it's 9/3 not 8/3)
After fixing the mail fc, this rom is very stable except for one lingering issue. I guess it might be wifi related. I went all day without any issues with wifi on constantly (and bt) but when I left work (and seemingly as soon as I got out of wifi range) the phone was locked up with nothing on the screen, unresponsive. I had to pull the battery. This has happened since RC3 for me. I am going to try it without wifi over the weekend. Otherwise, BT streaming adio now works perfect, and the internal memory gets scanned for pics/images. I'm going to keep running it though as this wifi bug should be fixed soon.
not to mention we're commenting on it in the more official thread posted up by the author of the rom .
http://forum.xda-developers.com/showthread.php?t=755690&page=111
however just to say it.. so far its running quite well, I found a correlation between wifi and BT causing issues with each other... commented on it in the other main thread after some extensive testing today.

Yes, there definitely is still issues with wifi. The issue seems to be exacerbated when running SetCPU with a profile that underclocks when the screen is turned off. Since I've stopped using SetCPU I havent had a single freeze, although I might have just gotten lucky so far.
SetCPU will not run at startup for me, even with the option checked to start at boot. I had to set Tasker to run it at boot as a workaround.
When phone is in Airplane mode I still am able to recieve text messages.

I would have to second the issue with SetCPU. As soon as I overclocked it and began using the rom I noticed the phone would get hot abnormally fast and would reboot a few times within the first few hours. Not sure what is going on here as it worked fine on the RC.

I believe the thread referenced by you refers to RC3, whereas I am specifically looking for feedback on the newest numerical releases of CM 6 for the incredible.
Update: leaving battery percentage at 91 before bed with system panel running, will see whats eating up the most juice. So far stable n fast with no issues (except LCDs).
I get random reboots and freezes every thirty minutes if so on a fresh wipe of 6.0.3 I tried with setcpu and without but always with the built in hotspot running. Same issue since RC3
LED notifications dont work. LauncherPro Plus FCs on every reboot, other then those things im good with it, great wallpapers , great rom

[Q] No GPS receipt with Kernel SpeedMod K9A

I have installed the Kernel SpeedMod K9A on my Galaxy S.
The GPS receipt is complete down, I think in the beginning with the speed Kernel (i1-2) the GPS receipt was fine.
The LBSTestMode show under „Get position test“
DOE: 1 Azimuth: xxx
System: 11:53:52 on in 2010-11-27
Elapsed (Sat): X.xxx (second)
No Satellites are found.
If I wipe the phone, the receipt is again fine.
Then the LBSTestMode indicates no entry DOE.
If I Recovery my Data back via Restore Mode, the error appears again.
I already try JI6, I followed "xda-developers - View Single Post - GPS still not working after JI6 Update- Please help", I used FasterFix for Europe settings in gps.conf- nothing.
Can anybody help me without: “so, make a wipe”
weird , i also installed K9A and didn't wipe a phone but the GPS work fine.
i use DXJPA.

SpeedMod lagfix and GPS performance.
Old thread but I just found it while searching for information on the issue I will describe below. Maybe this has already been addressed elsewhere and if so I apologize but I could not find info on this anywhere.
It has to do with SpeedMod Kernel, the lagfix options and GPS performance.
I am running on Doc’s 9.6.6 ROM, XFJS5, JPY modem.
Until yesterday I had SpeedMod 13KA with the tweaks (first 4 enabled) and lagfix (first 3 on ext4 the loop ones on ext2; no system conversion and Bind_data=false). My GPS reception was horrible – loooong times to lock and very inaccurate, jumping all around the map, lagging behind and loosing signal easily.
Yesterday I swiched to SpeedMod K13B, I enabled the tweaks and default lagfix but without touching DATA_LOOP, CACHE_LOOP & DBDATA_LOOP settings. These remained “=false”. My GPS performance improved miraculously! Lock in fewer than 10 seconds, accuracy 5-10 meters.
This morning I put data_loop, cache_loop and dbdata_loop on EXT2. GPS performance was terrible again. I used GPS Test and I could only find 1 (one!) satellite in over a minute of waiting under open, clear sky. I then disabled all the LOOPs again (all “=false”), and behold! I could find 7 satellites in less than 10 second, locked on 6 of them in 12 seconds and on the 7th in less than 20 seconds. Accuracy was 5 meters.
Do you know why this happens?
Today I installed the K13E version on my stock Froyo 2.2.1 device and I have the exact same problem:
The GPS device will just find 1 satelite and no fix. I have only replaced the stock kernel (J5) and haven't applied any lag fixes yet.
Does anyone perhaps know of a fix for this? Could anyone maybe explain how and where to set the abovementioned changes?
Many thanks in advance!
Maybe it is hardware related. Try this?

[Q] GPS Loses fix (and precision) when screen off

Hi people!
On my Galaxy S i9000 I have on Juwe 5.3 (JVR) with Semaphore 1.6.0.
I have the following problem: my GPS works (good accuracy and locking speed) only when the screen is on. As soon as the screen goes off, I lose the fix and precision, while using tracking apps like Runkeeper or My Tracks and diagnostic ones like GPS Status.
I've tried to force the CPU on 1000 MHz with Voltage Control but the problem remains so I'm guessing it's not a performance issue.
Any ideas?
Everything else works fine.
Thanks!
The same happens on my phone (albeit w/ CM7), but I don't mind, since that would eat the battery. I can see how that would render certain apps useless, though. I've used a few ROMs in my day, and never noticed GPS staying locked while the screen was off. I'm interested in how you'd achieve this as well.
Hi.
Yes in fact when I was on stock the gps worked as expected but I was on froyo.
Than I updated to a beta GB and then to Juwe.
I'd prefer not to put a froyo rom just to test if possible. I'll wait for someone to come with some idea
Thanks!
Some updates:
- It seems not to be kernel releated (tried with both semaphore and CF-Root, will try also TalonDEV)
- Not rom releated also (from Juwe JVR to Simplicity JVT, passing thru stock JVT).
Any ideas?
Is there someone whose GPS stays locked even if the screen is off?
Thanks.
Interested as well. Anyone?
Hmm, my gps would always lose lock if i turned off screen (froyo too).. thought that was normal behaviour
i thought that depends on the app. navigon has a setting which says to keep gps on or off when minimised.

Probably this is right. Should be app-related.
I used to have a lot of GPS problems, but I solved them connecting GPS for the first time with WiFi on google maps, after that, GPs worked great without wifi being necessary anymore.

It seems that also other phones are affected by this problem/feature, after the update to Gingerbread.
Little update: the navigation app does not let the screen to turn off to not to lose gps fix.

[Q] S5Elite 4.4.2 Rom misbehaviour

The last 3 days i have the Rom from MaHo_66 that can be found here : http://forum.xda-developers.com/galaxy-s3/development-i9305/rom-4-4-2-t2863060
Since i have so little posts(used to get a solutions all these years) but not a new member i can't post in the Rom's Thread i made a new one here. So some questions :
1) If we don't want the 3dot menu from S5 because of loosing space in the screen how can we add the official Alarm/Clock every Android device has?
2) Because of the device's BAD consumption when Data is on, and since in my country Data costs a lot, i wanna have only H and H+ in my device and not 4G-LTE.
Why when i choose wcdma only in Network Mode i get only 4G or 4GLte ? Also read the http://forum.xda- developers.com/galaxy-s3/help-i9305/s3-lte-i9305-3g-4g-2g-wokring-help-t2246437 with both automatic option enabled, or WCDMA only with every band available but nothing happened..
3) With every other rom 4.1.2 or 4.3 i had at least 2 hours of screen and about 1 hour of talking with one charge.. That one gives me only the half of it.
I noticed that an app that's running called: com.android.systemui, with included Packages of System UI, com.android.keyguard and com.sec.android.sviewcover,
eats about 5% to 10% in the usage of one charge. Generally with normal use of phone i had more than 12 hours that i got last time with that Rom..
Just to be clear,before installing the rom i cleaned Everything, and installed with DEFAULT values and no tweaks at all.
So ANYONE has any ideas for my questions?

1) The 3 dot is the menu key. You have a hardware menu key. IF when you press it you get taken to the task manager, press and hold it.
2) This depends on the implementation, but 4G/LTE should be less battery hungry than 3G/HSPA (but not 2G/GPRS) due to rush-to-idle of 4G. keyword here is SHOULD
3) com.sec.android.sviewcover is irrelevant to us, we don't have the hardware sensor to enable it. I would advise you to run Better Battery Stats to get a proper diagnostic of your battery usage.

Well daedric Thank you for answering so quick my questions. Still im sorry for my late response, cause i had net issues.
About the Rom : i don't want the 3Dot Menu cause we have hardware keys for that.. I found the clockapackage and flashed it but it gives me an error every single time i try to run it.
Well also the signal for data values was a problem too, and MaHo_66 gave a solution. Battery still drains fast especiaally when i have the data open it takes about 160 or less minutes with screen on.. Can't help it!
Thanks again for your response!

WiFi Turning Off During Deep Sleep

Hi all,
Can anyone help with this issue. I can see no long discussion about it which seems to suggest it's either rare (not great) or something I am doing (probably).
My WiFi status appears to be fine throughout the day, when in regular use. I have no speed issues (connection speeds as expected for my home internet), no random drops or on/off switches and no seeming battery drain. I have all additional services on (Bluetooth, location and NFC as I want the phone to be fully functional at all times and not just 'look nice') and despite this I get what I would expect in battery life (c. 6 hrs screen on time). YET, amongst a few other problems (what is the slider customisation about - awful!) the one I can't fathom is this:
My WiFi switches off over night presumably when the phone goes into deep sleep. I have gone into the advanced settings and set it to 'Always on' but this doesn't seem to keep it 'always on'. I wake up in the morning and it is off. I was running some Tasker profiles (which seem to make little difference given the slider issue noted above) but actually my WiFi isn't one off the Tasks effected by a night time profile.
Any help would be appreciated.
AS a secondary question, I switched my VPN over to Canada as suggested and was provided with the Nougat update. I haven't yet tried it but was wondering if there are any bugs that I should consider before switching over given I am 4 days into owning this phone and still haven't ironed out certain things in Marshmallow.
Just as a follow up question, would the 'turn Doze off' option help with this? Surely I shouldn't have to do this though?
Am I the only one having this issue? That would suck. Even so, would anybody more adept at these things than me like to have a guess at solving the issue.
IV had agresive dose mode on and haven't had any wifi problems but I am on 4.0.1 so might want to just update it as it's really stable and I haven't had any issue except having to reconfigure the APN settings. PS if you do update reset you phone after as some people have said it helps with the new file system.

This happens when people is crying about updates every day. Then, when the updates are available, they update it in the first minute and again, they start crying, that they encounter bugs and stuff that doesnt work as it should, even if they dont have any idea how to revert their OS to the previous working one. People should learn how to be patient and enjoy their phones without being so greedy about updates.
Just sit tight, enjoy your phone, READ forums about latest updates and the problems encountered on that specific update ( since its still a beta update, and an early one , called Beta 1 ). If they seem to be fine with those issue, ONLY then should update to the latest one.

I haven't 'cried' about anything, pal, so keep your unhelpful comments to yourself or help. Don't middle ground-it by offering your own personal, and incorrect, opinions.
I hadn't upgraded anything, I was running stock OS and stock marshmallow, so I had literally done nothing to my device other than switch it on and download the same apps I've been using for years.
I've also rooted several devices in the past with no issues and chime in when I can to help, but I'm not a dev and there are far more technologically gifted individuals operating in this forum which is why I sought help here... Not that I got much from you. But I'm more than capable of reading release notes and making sure I can revert backwards before installing anything.
Now to anyone still here, and with the same issue, it appears that carrying out the update to Nougat, re-adding my WiFi networks and clearing system cache solved the problem or at least for the first night. Should this change I'll update here.

Hi Iso, thank you for your response, I hadn't seen this until now.
The upgrade to 4.0.1 does appear to have done the trick somewhat as it stayed on overnight without issue. I did notice it wasn't on a little later this morning but I am giving the device the benefit of the doubt on that one as I have been messing about with certain things and it's possible I or a profile in tasker switched it off.
As an aside do you recommend any other potential fixes, just to be on the safe side.
Did you factory reset after upgrading? Other than that it's probably a app you have I hear Facebook is really bad at battery

I didn't factory reset, only Cache wipe after the upgrade, and as it seems ok so far, I am reluctant to factory reset the device as it took so long to set up in the first instance.
Should it start becoming an issue again I'll try it but for now...
Also I know there are backup options though I haven't found one that works flawlessly which gives me the confidence to explore this avenue just yet.
You might have to because in nuogat they optimized the file system and in order to get the new one you have to factory reset not 100% sure it affects battery life but it really affects performance, PS also try turning off gestures, ambient display and pocket mode

Are you sure ISO? The UI has been updated and the already snappy OS feels snappier. Is there a way to tell for sure if it's required?
If so, any good recommendations for backup capability. I have used Helium to mixed results and I can't use Titanium as I have no root (and don't wish to).
Maybe not but it all elts fails
