Well, I'm glad the issue of modem is brought up.

Ever since I upgraded from LOS 14 to LOS 16 (about 5 months ago) in my I9195 I've been having connection issues.

At first I thought it was LOS, so I upgraded several times (fresh install w/wipe), sadly with no luck. Phone kept getting SMS from 1hr up to 1day after the original message was sent. Network connection (cellular) would also be dropped and only after a restart would I get connection back up. Calls... well, I was lucky if I got one or two. Most of the time my number was unavailable for the caller.

I discovered the modem thread here in xda and tried flashing modem with different versions. Some would be ok for a day or two before dropping connection again (and only after a restart would I get network connection back up).

I was thinking, could my internal storage be dying somehow? Is my modem all of a sudden gone bad?

Next step was going to be going back to LOS 15 or 14, but I got kind of tired of flashing 1-2 times a week.

Would love to hear if anyone had similar problem, or just if anyone could comment.

TIA

There is a problem with the modem . No one was engaged in the modem ,did not rebuild it for a specific version of Android and device. There are only old modems that were on kit-kat . Need logs errors and putting here (can developers rebuild a new modem for all three devices..!

---------- Post added at 05:31 AM ---------- Previous post was at 05:18 AM ----------

There is a modem l9191XXUCOA2 that comes in the latest firmware, but it is not perfect . The mobile data icon in the curtain turns on with some delay, the connection sometimes falls off from 3G to 2G or there is no network at all (a reboot helps).These are all symptoms of a non-full modem. Request to developers rebuild a normal modem !!!

By the way it could be because of the core too !
[Galaxy S 4 Mini Original Android Development] Jaroslav.100:
Still 3G Internet only with sim 1 , sim 2 only 2G. Dear arco68 ! Please pay attention to these errors and correct them if possible !!!
[Galaxy S 4 Mini Original Android Development] Claudio4780:
You should pay attention that the GT-I9192 Duos is not capable of 4g (LTE). It's hardware related, not software and it can operate only via 3G (Sim-1) & 2G (Sim-2).

arco, thank you for your great work!
[Galaxy S 4 Mini Original Android Development] Jaroslav.100:
You probably don't understand me..I'm talking about the fact that 3G is only on one SIM card ,but should be on two.
[Galaxy S 4 Mini Original Android Development] Claudio4780:
YOU are wrong. SIM-1 can operate on 2&3G, SIM-2 on 2G ONLY
[Galaxy S 4 Mini Original Android Development] Jaroslav.100:
Maybe it's only on this phone. Well all the same it is necessary to rebuild the modem (it will not prevent) and the kernel to look, something not so..

GPS also does not work adequately (helps again restart..
[Galaxy S 4 Mini Original Android Development] Arslan140:
That's hardware limitation and you cannot possibly do anything about it with software

You can enable 3G on 2nd sim by turning Sim 1 to 2G

You cannot get 3G on both Sims at the Same time

There are wishes: in the kernel, the CPU regulator should be translated into default performance, and the same thing should be done in the GPU, who can rebuild the kernel for the GT-I9192? Or give a link to the kernel sources for nine, including the kernel configuration.
[Galaxy S 4 Mini Original Android Development] arco68:
Added builds for serranoltespr (SPH-L520) and serranolteusc (SCH-R890).
[Galaxy S 4 Mini Original Android Development] arco68:
Why do you want to run the CPU constantly in performance mode? That's just going to heat up the phone and make the battery go out way faster. If you REALLY want to do that, you can already do that by enabling performance mode in battery settings.

Adding kernel tweaks/hacks to manipulate the CPU and GPU frequencies is something I will never do, as it will compromise the general stability.

There is dust in your proximity sensor. Clean it or enable end call with volume button.
[Galaxy S 4 Mini Original Android Development] so_bek:
For those of you not having issues with the modem, what firmware version are you using?

My modem seems to have issues coping with changing channel conditions. Every few days it indicates no network service and i either have to go into the settings to manually select the carrier, at whcih point it jumps back to good service, or i have to do a reboot to get it back to work.
[Galaxy S 4 Mini Original Android Development] Milpr:
I don't think it's a sensor because I have 2 s4 mini duos phones and they both have the same and besides when the screen goes blank without talking, the home button doesn't want to wake it up either.
[Galaxy S 4 Mini Original Android Development] kurtn:
End call with power button. Use an app to check signal of proximity sensor

[MENTION=3044346]arco68[/MENTION] - I'm running your build for SCH-R890 this morning and find that gps doesn't work unless I replace /system/etc/gps.conf with https://github.com/jlask/android_device_samsung_serranolteusc/blob/lineage-16.0/rootdir/etc/gps.conf one.

As far as the other difference in your build, ro.telephony.default_cdma_sub=1 (instead of 0), I am not noticing any difference (mobile data still works).
[Galaxy S 4 Mini Original Android Development] arco68:
Thanks for the feedback. Is this the issue we previously fixed with LPP_PROFILE = 3 ?

[Galaxy S 4 Mini Original Android Development] jason972000:
Regarding gps on SCH-R890, it actually does work about the same with your PIe build vs. the gps.conf differences.

I did more testing between the two gps.conf versions and it seems like it can take several minutes before getting a fix where the latitude/longitude appear to be displayed.

Back on all previous versions, the wait for a fix was usually less then 1 minute but with Pie it seems it can take several minutes or not work at all. The past few days I had a really hard time getting a fix at all. This morning I can get a fix after about 2 minutes of waiting.

I wonder if the switch in radio blobs has anything to do with it?

Yes, back when you helped me with getting gps to function better, it was the LPP_PROFILE = 3 and I think also the CAPABILITIES=0x33 both had seem to help at that time. But with Pie I cannot say for sure anymore since your rom does have working gps this morning.
[Galaxy S 4 Mini Original Android Development] arco68:
Yeah I think I mentioned it somewhere else, that ever since Google broke Glonass for legacy devices, GPS has been getting progressively worse every Android version. Sadly there's not much we can do about it, since we don't have any newer blobs.

Not me. I've the same: I have it mostly after entering an area (e.g. basement, cellar) where signal is too weak it looses connection and then it cannot regain it. Reboot is the only remedy - I cannot even select the carrier, tapping on it says service not available (or something similiar). I'm using Modem I9195XXUCQL2

Black Screen problem

How do I fix the black screen problem? The version 16.0 only worked once a few months ago. After that, every time I installed the ROM, when I started the system for the first time I got a black screen. If I press the middle button, only the extra button lights are on. If I hold the power button, the shutdown and restart menu appears on the screen, however, the background remains black. I waited more than half an hour to see if the screen finally worked, but it didn't.

I left version 15.1 because it was restarting my phone several times, draining the battery super fast and was super hot all the time. Not to mention that when I installed this version I had the same black screen problem, but I let the battery charge and went to sleep. When I woke up the screen was back to normal. My S4 Mini is i9192.
[Galaxy S 4 Mini Original Android Development] Arslan140:
Screen goes black for my i9192 too(only on lineage 16 not facing on lineage 14 at all) but pressing power button two times fixes that I face this issue monthly ago it happens once or two every day but November or December build somehow fix that

But with Jun build (using for two weeks) same problem happens two times

But your issue is much more than mine

My device doesn't got hot during black screen and it's just matter of sec to fix

And regarding black screen at first system start that hasn't happened to me

I got black screen only while playing media files that's it and I do play alot of videos but black screen only happens one or two time

So this issue doesn't bother me.

My recommendations is to use older build try November or December
[Galaxy S 4 Mini Original Android Development] Fimosento:
First thanks for responding. I already used the December version and the same thing happened, it was on the black screen after rebooting when installing the ROM. After I made the first comment above, I spent another 30 minutes hanging up and restarting my phone several times until I finally turned on the screen. I configured everything I wanted, the problem is that the phone is quite hot (probably because it's an old battery since I bought this phone in 2014) and often the wifi icon on the top bar doesn't work, forcing me to go there in settings wifi and disable/activate over there. Right now I had to turn the wifi off in settings, but the wifi icon shows it as if it were on, completely locked in the notification bar.

Edit 1: Now it's back to black screen. Then an interface error appeared that stopped working.
[Galaxy S 4 Mini Original Android Development] tM&M:
I've had that same issue after upgrading from Android 7 without formatting. It would work fine for a few hours or a day, then would give interface crash errors and I had to reinstall the ROM.

Since I've installed it clean, it has been running perfectly. I've installed again most of the apps and configurations I had with the previous Android version.
[Galaxy S 4 Mini Original Android Development] arco68:
To be honest, it sounds like a hardware issue. Flash stock rom and verify if there's issues there too.
[Galaxy S 4 Mini Original Android Development] Fimosento:
The clean formatting you say is to wipe DALVIK CACHE, SYSTEM, CACHE, DATA AND INTERNAL STORAGE? If so, I always do this when I install a new version of android.

In version 14.1 I didn't have this black screen problem when restarting the system after giving a wipe. The problems were more in some options in configurations that freeze the screen, which still occurs in versions 15.1 and 16.0, however I manage to minimize and do something else while this conflict fixes itself.

---------- Post added at 10:41 PM ---------- Previous post was at 10:30 PM ----------

I confess that I also suspected it could be hardware, but I don't know where. The first time I opened this phone, I was afraid to break the plastic case because it was too hard to get out. So I used a screwdriver to unlock each part of this cover and damaged the components responsible for the camera and flash. That is, neither of these two work today. I always force the stop and disable the camera app so as not to cause conflicts.

Regarding testing the Stock ROM, I will stay a few more days with this version 16.0. At the moment it is working well and didn't give any black screen during the day. It also appears to operate better than version 15.1.
[Galaxy S 4 Mini Original Android Development] tM&M:
Yes, I meant full format of every partition on the smartphone, including boot.

I didn't restore any data, even from cloud backups. In the end I'm not sure if it was a bug somewhere, as I installed most of the apps again and configured the same way.

I'd say try without restoring any kind of backup and give it a couple of days.

There's also some merit in running adb on recovery and doing an 'fstrim' of the partitions (mounted), as the eMMC chip supports it but the kernel and OS don't, so it causes problems and slow downs.
[Galaxy S 4 Mini Original Android Development] arco68:
There you have it. This is what's causing the issues. The kernel and the rom is expecting a working camera. If they can't find any, the services and drivers for it will constantly crash, keep the device to not go into fully suspend, and cause deadlocks in the system.

"set warranty bit kernel" is normal, when using custom rom. Bootloader just sets a flag that Warranty has gone.

Mobile data not working

I have an I9192. It was running with no problems on latest Samsung KitKat I9192UBSCQB1 (latest build from 2017).

I flashed the March edition of LineageOS 16.0, tested it and it was mostly OK, except for mobile data, which was not working.

I tried toggling different settings / setting up APN manually / clearing cache, etc... Since I had the latest Samsung firmware, I suppose this is not an issue with the old baseband. Does anybody have a clue what the problem with the mobile data might be?

Speaker not working

The Galaxy S4 mini was my first real smart phone. As mine is broken since some years, I bought now a used one I9195 for very small money. Last weekend I updated the firmware to the newest version. Then I flashed the latest Lineage OS 16 from this site to my phone via Odin. The phone booted without any problems the new OS, everything looks fine so far.

Then my wife asked for music, so I started Youtube. It started streaming, the music was loud and clear over the built-in speaker - for around 1 minute, then the music stopped. The phone was still streaming, but the speaker was quiet. I suspected a problem with the small RAM and reduced the streaming bandwidth, which gave me another around 10 seconds of music via the speaker. A further bandwidth reduction brought me some more seconds of sound, but since then the speaker is quiet - no music, no alarm, no ringtones via the speaker. With a head phone plugged in, there are no problems with the sound. Any ideas?
[Galaxy S 4 Mini Original Android Development] kurtn:
Bad electrical contacts. The S4 mini is easy to repair. Get a good screw driver.
[Galaxy S 4 Mini Original Android Development] IronRoo:
before you follow Kurtn advice (which is good) I assure you have rebooted and also tried with another app after rebooting eg music player.

Also I had a similar issue a couple of years ago on old version Lineage (maybe even Cyanogenmod) anyhow it was some issue with AudioFX app, think I just turned It off and on and sound worked again (maybe deleted AudioFX app data ... Can't real exactly)
[Galaxy S 4 Mini Original Android Development] MoreWalter:
Before I installed the Lineage OS, I played with the S4 mini, the sound through the speaker was ok.

After fully charging the battery I just rebooted the phone into Lineage OS again, and now I am listening Kiss on Youtube through the speaker (while I am typing here), so the speaker is working fine. Therefore I would exclude a hardware defect ;)

After half an hour with Kiss and Metallica, the speaker is still working. So for the moment the problem is not reproducible.

---------- Post added at 09:33 PM ---------- Previous post was at 09:16 PM ----------

Yes, I had rebooted several times, but to no success, the speaker did not work. The only what I did now was to discharge the battery to zero (by accident) and then charge to 100%. I will now observe, if the battery charge level has an impact on the speaker.

Anyhow I am very happy with the Lineage OS on my small phone, I am glad to have my small beast back with a modern OS.

Display missing updates

Hi, I've switched to this S4mini for tracking my blood sugar. Running xDrip (often in the foreground), I sometimes don't get an updated display. Last build (March 11), no display lock set. The app (and its data source, LibreLink) appears to be working and not missing any data (battery de-optimized, notification anchor set). Even my Sony smart watch gets current data.

Is there a way to track this down?

Music keeps playing after headphone is plugged out

Hi Arco!

After two years of using the last official LOS 14.1 build I compiled LOS 16.0 with MicroG from your sources. (BTW: It is so awesome that you publish all the sources right away!)

Everything is fine but there is one thing: If I plug out the headphones while music is playing (Eleven Player) the music keeps going through the speakers. This did not happen in LOS 14.1.

Is this a known issue? I really like Eleven, I could try another player if this issue is not known.

Keep going and stay healthy :)
[Galaxy S 4 Mini Original Android Development] IronRoo:
OK good, I should have mentioned a battery pull ?, though i've not heard it fixing a speaker issue like this before.
[Galaxy S 4 Mini Original Android Development] kurtn:
I don't think it's voltage taken away, but squeezing if case that "repaired" the speaker.
[Galaxy S 4 Mini Original Android Development] IronRoo:
Sounds like your settings are correct, but I have no idea what that app is, might be good if you can find a forum for that as well.

How's it connected? Bluetooth? There are a number of Bluetooth settings available if you activate developer options that possibly might help if it's the Bluetooth that is the problem
