[Samsung Galaxy S 4 Unified Development] Eguy:
Glad to hear your recovery is going alright. I did not have the black screen problem on the April build, but I had tons of other issues that have been resolved. I will also note that I haven't had the black screen in the last week, it seems to be pretty rare and sporadic. Different apps, too. For me, the whole thing reboots the phone though, it's not a system UI restart. I am running the 10/09 build.
[Samsung Galaxy S 4 Unified Development] Max Frost:
hmmm , that's weird then . When mine goes black it doesnt reboot at all. It just goes black and doesn't respond to anything except maybe a vibration when I press the power button for a couple of seconds. Then after a total of about 10 to 12 seconds it recovers to the lockscreen. This might be some phantom issue that works itself out in another build or two.
[Samsung Galaxy S 4 Unified Development] wilsonhlacerda:
Are you running apps like Gravity Screen, KinScreen or similar?

Or app Maxlock or similar?

Since Android 7 sometimes I have something similar to your problem and as far I could narrow it the root cause seems to be related the above tools (I do use Gravity + Maxlock on EdXposed mode).

---------- Post added at 11:32 PM ---------- Previous post was at 11:29 PM ----------

Are you using Adoptable Storage? Or Apps2SD? If so maybe related to some problem while accessing external SDCARD.
[Samsung Galaxy S 4 Unified Development] Eguy:
Nope, don't even have a SD in the phone.
[Samsung Galaxy S 4 Unified Development] Max Frost:
No , just bare bones install testing ,it's likely just a hiccup and hasn't done it lately.

Hi there !

I never had no sim card issue but it appears on last build on my jflte.

Can someone confirm ?

Regards !
[Samsung Galaxy S 4 Unified Development] Max Frost:
Jfltespr/sphl720

[MENTION=3044346]arco68[/MENTION] , [MENTION=5848265]npjohnson[/MENTION] . Just wanted to let you know of a problem that seems to be tied to the sim card fix you did recently. I hope you still have the list of things you were adding and subtracting. As you know I had an operation that's kept me pretty much in recovery for 11 weeks but going back and forth to town for checkup's this week revealed an issue . I'm unable to turn on location without instantly knocking out mobile data and telephony . What happens is one minute your data and telephony are fine. You turn on location and instantly the data and telephony icons turn off and then start trying to work again so the icons are flicking on and off with an x on them . Just a constant cycle every couple of seconds . Turn Location off and instantly data and telephony turn on and work fine again. I have tried a couple of clean flashes to confirm the issue . Also tried an older build. Today I'm going to reload the CRD rom to confirm whether this issue was present with that one. I live in the country and don't often leave here so I'm just discovering this. I am going back into scientific test mode for you in hopes of logging this for you properly so you can fix it. It's definitely something going haywire between them. I'll holler back my friends. Thanks
[Samsung Galaxy S 4 Unified Development] Max Frost:
Location

[MENTION=3044346]arco68[/MENTION] , I've narrowed it down quite a bit. Here's what I'm finding.

I can flash the rom , gapps , reboot , data works fine , turn on location and it all continues to work until any app begins to access location. Until I start getting apps from the play store it works. So if you try to use maps as an example it totally knocks out data and it turns on and off , on and off. Exit maps and in a few moments data is back working fine with location turned on. So the problem is not that they are both on but when location is accessed with any app , I mean any app this happens. You know how when you make a call it's normal that you see mobile data turn off during the phone call ? It's almost similar to that effect except with an app accessing location it keeps jumping back and forth , data on, data off , repeating this behavior. Could it be one of those items you removed when we were working on data recently ? This is happening on both of my s4's. Standing by to help. Thanks
[Samsung Galaxy S 4 Unified Development] n0b0dy666:
Is today's build (lineage-17.1-20201105-nightly-jfltexx-signed) broken - not fully booting? It boots to the system, shows "Phone is starting" and eventually reboots to do the same again. Reverting back to previous nightly works. I forgot to grab logcat, but I can do it later today or tomorrow.
[Samsung Galaxy S 4 Unified Development] kurtn:

Hi , this rom is great i have only one problem with the speakerphone.

I noticed that during a call using whatsapp or google duo,even if i activate the speakerphone , the audio only comes out from the little call speaker on top .

Speakerphone (audio from the bottom speaker) works only sometimes during a call using Facebook messenger lite.

Does anyone have this issue ? Could you help me ?

Thank you for your support with this great rom .

Location/Data

Hi [MENTION=3044346]arco68[/MENTION] , [MENTION=5848265]npjohnson[/MENTION]. Tested a little more on the location problem knocking out data. I did install and confirm that the issue is not present on the CRD build for the L720 . The issue only occurs on the Lineage rom at the moment any app starts using location. Location on co-exists with data and telephony until the moment you open an app that starts accessing location and it's like location hijacks data and until you close that app they go back and forth in a cycle knocking each other out. Here's a log that hopefully contain what you need. Everything related in the log will occur between 14:36:00 and 14:36:59 Also , when you close the app , example google mapps , in a few seconds locations and data once again turn on and co-exist until the next occurrence that location is used again.. Hope this helps. Rom is fabulous otherwise . Loving it.
[Samsung Galaxy S 4 Unified Development] rjt2291:
Has anyone else gotten these kind of lock-ups? Basically the phone is sitting doing nothing and all of a sudden I could look over at it and the screen is all black with (I think) 5 horizontal white bars equally spaced. The phone is completely unresponsive and have to hold power button till it turns off. Phone behaves normally on restart.

This has only ever happened like 3 times over the last 6 months, so it's rare.
[Samsung Galaxy S 4 Unified Development] rw_on_xda:
I have seen this white bars with lineage-17.1-20201105-nightly-jfltexx-signed, what's pulled from download cause of bugs.
[Samsung Galaxy S 4 Unified Development] vip5912:

[Samsung Galaxy S 4 Unified Development] x2k13:
[MENTION=5848265]npjohnson[/MENTION] and all others: Does NFC work for anyone of you on jfltexx i9505?

I enabled it but NFC Tools doesn't recognize anything (does so on another phone I have running LOS 17.1).

What's odd about it is, when I disable NFC, the app complains it is disabled (as it should do), but when enabled, the app sees it as enabled, but the sensor doesn't get activated or something.

Two reasons I guess:

1. NFC is enabled but the sensor is not

2. The sensor is broken

For 2. - can't check that on my own and I doubt it is.
[Samsung Galaxy S 4 Unified Development] npjohnson:
it works just fine for me. Have you replaced the battery? If so does your replacement have an FC on it? My bet is probably no
[Samsung Galaxy S 4 Unified Development] x2k13:
Nope it's the original battery that came with the phone, it says "Near Field Communication" at the top under the SAMSUNG brand logo.

Just to make sure it isn't the battery I ordered a new one. Will tell if it's working with the replacement, NFC of course.
[Samsung Galaxy S 4 Unified Development] wilsonhlacerda:
Tip: Nohon batteries are really good and their NFC version does work. You can find their official store (and other sellers) on Aliexpress.
[Samsung Galaxy S 4 Unified Development] x2k13:
[MENTION=5848265]npjohnson[/MENTION] I'm a bit confused, I read somewhere there has been versions of the battery cover with antennas, like these:

https://fscl01.fonpit.de/userfiles/...ery-Cover-NFC-Candy-Color-Fruit-Color-NFC.jpg

It says S4 9500 in the link so it probably is referring to S4 i9500's? I don't have anything like that in the back cover, just an empty area shaped like the antennas on the pic, so I assume that (hopefully) doesn't apply to the i9505?

Hmmm... thank you Samsung for messing with my mind, lol.

---------- Post added at 10:41 AM ---------- Previous post was at 10:24 AM ----------

Thanks for the hint, I've ordered an original NFC Samsung already. We'll see if that helps.
[Samsung Galaxy S 4 Unified Development] wilsonhlacerda:
There's no original for years. Samsung does not produce them anymore.

99,99% of "original" out there are cheap fakes. And worst part: bad quality, low actual power and sometimes bad charging circuit.
[Samsung Galaxy S 4 Unified Development] x2k13:
Ouch. Well, if it doesn't work I can send it back without any comment and get my money back, good to live in the EU legislation area which permits customers to do that.

At least I can check if NFC works or not...
[Samsung Galaxy S 4 Unified Development] wilsonhlacerda:
In Europe those guys have good batteries. Also with or without NFC versions: https://www.polarcell.de

Besides their website, they themselves sell on eBay.
[Samsung Galaxy S 4 Unified Development] bersem:
I bought an Anker replacement battery few months ago. Its also a good replacement battery if can be found to buy.

[Samsung Galaxy S 4 Unified Development] RowanDDR:
Have you guys got edXposed working OK on this rom? For me, edXposed reports as "Active" (albeit with a "could not detect Verified boot state" warning), yet all the modules I try seem to think they are not enabled, or that xposed is not active. They are enabled..
[Samsung Galaxy S 4 Unified Development] x2k13:
Okay, battery arrived today. NFC seems to function, although I just managed to read one single card (electronic bus ticket). No credit or bank cards readable. My other LOS 17.1 phone, Motorola, can read all those different cards.

I guess the protocol support of the Samsung NFC hardware is pretty bad. At least NFC seems to do it now.

Care to post your battery drain in % per day ?

- others invited too -

Background:

*I* see ~10 % per day since some month, even though I have seen ~3 % per day in the past (maybe with a different ROM/Android Release)

my settings are:

- phone idle /without usage

- Wifi OFF

- 4G with mobile data OFF

- black theme

- ...?

CPU Spy reports Deep Sleep 97 %

battery is still the original and from 2013 if that matters

i have the same problem in all the october and november roms.
[Samsung Galaxy S 4 Unified Development] rw_on_xda:
investigating my battery drain (averagely 12,5 % per day with an idle (!) phone, also with a new battery)

while the new battery doesn't made any differences so far (after 2-3 charge cycles only), I decided to completely new install according to this guide:

Info about jfltexx | LineageOS Wiki

wiki.lineageos.org

I additionally decided not to install any app, just the pure OS.

looking through the settings and adjusting some, e.g. Sound, I found a bug:

deactivating "Link ring & notification volumes" (for the first time) leads instantly to an reboot.

anyone seeing this and/or the drain ?

btw: Is an bug report after an reboot of any use ?
[Samsung Galaxy S 4 Unified Development] rw_on_xda:
today I got an screen crash again and took a logcat just after it.

time when the screen crash occurred: around 12-16 01:11:25.015 and later (sorry can't read this sort of logs)

the logcat is here:

Ubuntu Pastebin

paste.ubuntu.com

what I did just before the screen crashed:

I tapped on an icon on the icon bar (naming ?).

it also occurred tapping on the status bar or the right part of the screen.

It's not reproducible.

it occurs from time to time, since the last 5-10 releases/weeks.

sometimes with an full reboot.

maybe related to my battery drain > 10 % per 24 h when the phone is idle (wifi, BT, etc., all OFF))

thoughts/comments/ideas/rotten fruits ?

P.S.

It seems I'm not alone with this bug:

[Samsung Galaxy S 4 Unified Development] sogt:
Yes, I can cause the screen to flicker / turn off.

"Sometimes the screen flashes magenta and then turns black. Lock with the power button and then switch back on, it will be fine.

In the Lineage Update menu, clicking on the options in the upper left always occurs. If it does not work, repeat it once again.

If I set "Disable HW overlays" to "on" in the developer settings, the error does not occur."

I put the factory ROM back, it didn't show this error.

Now I'm using Exodusnick Lineage 17.1 again.

Is it possible to somehow set "HW overlay" to permanent? Now after each power up I need to turn it on in the developer menu.

Hi all

I have just installed the 20201210 version of LOS 17.1 on my jftlexx / GT-i9505. I have noticed that the WLAN connection is spontaneously dropped after a few minutes.

I have a Fritzbox 7490 with up-to-date firmware and run-of-the-mill WiFi config.

This is actually an issue that my kminilte also has on LOS 17.1 unofficial.

What do you need from me to be able to better understand / diagnose this bug?

Cheers
[Samsung Galaxy S 4 Unified Development] pocketrule:
First, I'm no developer and therefore I can't help you if your problem is caused by a bug in the rom. The developers in general seek for a log, i.e. you could take a log soon after the error occurs. You can find information about it here:

https://xdaforums.com/t/tutorial-how-to-properly-post-a-bug.1520508/

If you're rooted, you could also install an app that takes the log.

Then it could be a problem caused by lineageos sources. Then this bug should be reported directly there. There are FAQs how to do it (for sure).

Two additional questions:

1) You've written, the error occurs with the build from 20201210. Have you tested previous builds and has the error been present there, too? This information could help narrow down when the problem first occured.

2) Have you checked you've got the newest modem / bootloader?

You can check it here:

running an 7590 (lastest stock FW, so it might not be very different) and an I9505 with lastest modem/BL (HQK1) I do not see this drops.

try lastest LOS 20201217

changelog:

LineageOS Downloads

download.lineageos.org

but *I* guess it's more the FW of the router.

you're aware of the claims in https://www.ip-phone-forum.de/ about the last AVM FW releases, so that people start thinking to sell their AVM stuff ?

- maybe try with fixed channel 100 (1000 MW versus 200 for channels < 100, see the AVM manuals => "Funkfrequenzen WLAN")

- or try the same (!) channel of the strongest neighbor

- play with WPA3 off

- maybe try AVM labor (~Beta) or inhouse (~alpha) FW

AFAIK some people saw some progress with it regarding their wifi bugs

labor:

SGH-M919 as i know is 3G only? You can check this in phone settings when you see LTE its 4g and working when not your phone will no longer work.
