I could give it a try on stable 5, later after work, i´ll flash stable 5 and check if i can get glonass fix (works on stock ROM and OptimizedCM 12.1, already tried that)

NOTE: Current GPS thumb with CM14.1 UNOFFICIAL LineageOS 14.1 for Galaxy S4 Jfltexx (GT-I9505) [S3ROOT]

Despite a good GPS fix, glonass isn´t working either and GPS (device only) has also random and automatic turns ON/OFF, like other ROM´s (MM and N (JDCTeam Stable 7 and 8 and Optimized Stable 4 and 5)) that i´ve tried.

It is fully working on JDCTeam AOSP MM

I wanted to install the rom because I have not read any comments on battery drainage but if the GPS but I do not understand, so what is the problem with the GPS?
[Galaxy S 4 i9505 Original Android Development] RuKaDa:
With all do respect to all developers who keep our S4 alive, essentially to JDCTeam,, i´m only trying to help as most as i can, to figure out this GPS issues that some of us are dealing with.

Flashed my S4 with the latest available build of [ROM][6.0.1][OFFICIAL] CyanogenMod 13 from cm archive (cm-13.0-20161218-NIGHTLY-jfltexx.zip), clean install with all the wipes. From all the MM and NG ROM´s available at XDA that i´ve tried, the CM13 was the only one that i could get the GPS properly working with almost instantaneously fix (even Glonass is working, as you all may check in the pictures).

Check the screenshots below, 1st capture was indoor near the window, 2nd capture outdoor at the balcony, both with clear skies with buildings around...

Hope that somehow this could be helpful, i´m looking forward to try AOSP with his powerful alucard Kernel, but without GPS it doesn´t fit my needs.

Best Regards to all
[Galaxy S 4 i9505 Original Android Development] iPAQ 6515a User:
GPS is working fine. The only detail is with Russian equivalent of GPS that is GLONASS. It can see those satellites but cannot connect to them.

Not a biggie, but a detail.

On MM by JDCTeam it works fully with GPS and GLONASS.

On another note, I noticed that 3c battery widget does not show correctly the current. When the phone is unplugged, the widget still shows +460mA instead of something in red.

A bug ? Or super ROM that charges while unplugged :D?

I personally don´t use third party apps to get GPS signal, i just use the navigation app (iGO Nextgen) from which i´m able to check the GPS information.
[Galaxy S 4 i9505 Original Android Development] Karls0:
You don't need. Just turn GPS on, wait for the fix, then wait few minutes longer to be double sure and make a screenshot of main screen of GPS status (this with something like radar on the middle) :).
[Galaxy S 4 i9505 Original Android Development] iPAQ 6515a User:
Yes, but for this you need to edit sys.txt in order to enable GLONASS as it is not visible by the app in its original settings. Therefore GPS Status is much simpler to use.
[Galaxy S 4 i9505 Original Android Development] RuKaDa:
You´re right, but you just need to add "show_glonass=1" in the [interface] section, i think that it couldn´t be more easier.

Ok, now it's clear. Still fix only on GPS. GLONASS is grey.
[Galaxy S 4 i9505 Original Android Development] smeroni68:
Guys, I'm silently reading your posts about glonass... but finally, also finding a older version of the rom where they get a fix... it's long time for sure that the problem is existing, but what's the problem if gps itself fix?

Also if you discover that a build of January was working, what's the deal of searching why glonass will not fix now? Is 1 meter better accuracy?

My personal point is that gps fix and also enough fast... so gps works. Finish.

I don't wanna be rude, but i really doubt that BB will loose a single minute to understand about glonass... his answer? Does gps fix? The function works, no need to find a fix.

Hope you understand that our free time is always less, so no time for all... and no time to search for perfection where the gain is null.

My 2 cents.

Like I said, not a biggie at all. Just stating the bug which is completely innocent in nature.

For me it is the best ROM out there, period.
[Galaxy S 4 i9505 Original Android Development] smeroni68:
To complete the status: all of you, knows that S4 is locked to Lollipop firmware... so having developed and managed MM and N over it is still a miracle.

I already showed a screen of MI5 AOSP N with gps and glonass working... so is not a rom problem, but or kernel or firmware... both these items are nearly EOF, so there is no meaning for dev to fix glonass until all gps satellites network will be in order and working!!

Fortunately glonass russian sat are in the same sky of gps... one system it's more than enought for your phone to know where you are over the earth. Isn't it?

Hope you get the point. If you like, you can live with our rom as it is... and anyway I can say fully working!! Someone do not agree with this? :confused:
[Galaxy S 4 i9505 Original Android Development] MatteoB92:
I agree with you at all, I just helped because I'm still on Stable 5 that for me is perfect standing at the users' feedback about Stable 6 and 7, but I must recognize you're doing a great work [emoji846]

Is anyone having a problem with magisk v13 where none of the modules work? I always get an error message saying that the resource or device is busy.

Solution for GPS problems in Samsung S4

Hi,

Many of you discussing for quite a long time about problems with GPS. I was also facing strange GPS behavior for couple of months like:

- can't get a fix at all (many satellites in view but 0 in use)

- get a fix but it takes a very long time (10-15 minutes)

- get a fix, but it is unstable (loosing signal, for example 5-7 times during 1,5 hour car ride)

I've tried many possible solutions found on the internet like switched to WiFi instead of mobile data (some say 4G is a problem), reinserted SIM card, installed dozen of application that promises to fix GPS ... sometimes GPS started to work but it was always temporary. I was started using this ROM since Stable5, but problem with GPS started with Samsung official ROM 4.4.2. Since then I've tried many ROMs to check GPS functionality (official Samsung ROMs 4.4.2 and 5.0.1, and all ROMs from stable 5 to 8). None of them solved my problem with GPS ... until I finally realized that this could be a hardware problem. It's obvious that hardware malfunction of some phones render problems that cannot be recreated by dev team. So, Please try to search the following phrase "gps hardware problem samsung s4". You'll find couple of pages with guidelines how to fix problem with GPS by disassembling the phone and "refresh" connection between GPS antenna and phone circuit board. As they say our Samsung S4 phones after some time (couple of years) looses connectivity because of dusty/rusty connectors that need to be cleaned/scratched. Many comments under this tutorials says it worked. It also worked for me. This is probably not an ultimate solution for all of You, but maybe some of you will find this trick useful. I was desperate and already planned to buy a new phone because of GPS problems ... but now when it has been fixed I'm looking forward for incoming stable builds of this great ROM :). Thanks JDCTeam!

EDIT: this trick greatly improve time of getting fix on visible GPS satellites. It does not resolve some software problem with GLONASS satellites. In my case they are visible (signal) but phone with Android 7.1.2 doesn't use them. Is there any chance to support GLONASS satellites in the future?
[Galaxy S 4 i9505 Original Android Development] Belgas14:
I had this problems myself, try to tight the chassis screws, somehow it fixed many problems I was having. Good luck
[Galaxy S 4 i9505 Original Android Development] StrusPedzi:
Have you installed Magisk 13.3? I had strange problems with Stable 8 ROM (clean install, barely few applications installed): force close of some application, one freeze when turning off the system. Sometimes restart solved some problems like no root for Titanium Backup. But generally there must be something wrong with root manager (Magisk). So, I've updated Magisk to version 13.3 (it was not automatic, finally I installed zip via recovery) ... and so far problems are gone.
[Galaxy S 4 i9505 Original Android Development] escrocu:
Hey,

I have an issue with this ROM. It seems that after a period of inactivity (can't exactly tell you a precise time) - let's say 15 to 30 minutes, I do not get any notifications for : mail received in Yahoo/Gmail app or the eBay app - I do not get notified that an auction I am following is going to end in 15 minutes. But if I unlock the screen (wake the phone) I instantly receive the emails or the notification for the eBay auction that is going to end in 15 minutes (although that is finished already). Alarms in the morning to wake me up function properly. Can anyone point me in the right direction ?

Thank you very much

Can I enable on screen navbar buttons and disable the capacitive ones?
[Galaxy S 4 i9505 Original Android Development] Serenata:
Hello,

firstly i'd like to say thank you all for all your effort. I've tried many popular roms and find this the best. I use it daily.

Unfortunately, with the previous version i had about 2.5 hours screen on time. After the update, battery lasts about 1-1.5 hours, half the time it did before. Anyone with the same issue?

This happens after clean install etc, as always. I've also tried to edit "cortex-brain" as i've read in here, but the issue remains.
[Galaxy S 4 i9505 Original Android Development] drrossum:
Your phone's power usage depends largely on CPU load.

Screen-Off-Time is limited by apps that keep your CPU from entering sleep state or waking up often. Android keeps apps running once they are started up. So any app you start after booting can in principle cause battery drain. I manually kill apps (in the app switcher) that keep draining (such as Strava). Browsers can also drain a lot. I prefer Opera above Chrome/Firefox/Dolphin for that reason.

Screen-On-Time is limited by high CPU load causing multiple cores to be plugged in. The solution is, again, to find out what app is causing high CPU load and find an alternative if possible. One way to do this is to run `top` in a adb shell when using your phone.

I use "power-efficient working cueues" to reduce core plugging. It may have a slight performance hit but in my opinion that's worth it.

P.S. cortex-brain uses very little power. It might affect Screen-Off-Time but not Screen-On-Time.
[Galaxy S 4 i9505 Original Android Development] Karls0:
You can do this by adding the following line at the end of build.prop file:

"qemu.hw.mainkeys=0" (without quotes)

To disable hardware keys you should look in settings I think it was somewhere there but I'm not sure, S4 is not my daily driver now. If the option is missing you can try to do it manuały by editing "Generic.kl" in /system/usr/keylayout. and comment lines (add # at the beginning) which contains menu, home and back button code (probably keys 139 158 172).

Do backup of this files before editing in case of restore or you will have to reinstall system.

Additionality you can turn off buttons backlight in settings if you want.
[Galaxy S 4 i9505 Original Android Development] Serenata:
I'm using my phone the same way with the same apps. In addition to my previous post, i've tried installing wizcyan rom, to check if this a battery issue. Well, with the same apps i made it to 2.5 hours screen-on time. Then, i wiped everything and installes the previous stable version of this rom, with which i also have about 2.5 hours screen on time. I'm using screen on time to make clear whati i mean, because i'm using the same apps and making the same usage in every rom.

In reality, with the previous version i had to charge my phone 1-2 times per day, while with the new version 2-3 times per day. So, is it only me?

PS. I also manually kill apps.

microG

[MENTION=3545504]smeroni68[/MENTION] Can the signature spoofing patch be included in this rom? I'd like to use MicroG instead of GAPPS. Patching this ROM a posteriori (e.g. with tingle from ale5000) is difficult because the rom is odexed.

If you prefer to not include signature spoofing, where can I get help building the ROM from source? I have a lot of experience with linux and kernel building but have not built a ROM from scratch before.

Thanks!

P.S. I see that sig spoofing is included in the JDCTeam's Optimized LineageOS 14.1 ROM
[Galaxy S 4 i9505 Original Android Development] smeroni68:
We spoke inside the team, but signature spoofing is not meant to be added in AOSP. Be careful because it's not always gold what bright! The spoofing can be used from a malicious app to stone sensible data from your phone!

[Galaxy S 4 i9505 Original Android Development] drrossum:
Thanks for the quick reply! I understand the decision, especially since the JDCTeam's LineageOS ROM can be used in this case.

I've been running no GAPPS since the July release and am quite happy with it! It felt bad to know that most of my phone's CPU cycles were used to track my location/usage etc. and not being able to prevent that.

I do miss the Google Cloud Messaging service, though, hence the need for microG.

MicroG is not compatible with Snapchat or Google play services. Not even worth having, if you really need it you can use MachineX Ron and use it. This ROM is perfect as it is :)
