Custom ROM becoming useless is a common issue on all Samsung phones. The community has not managed to reverse engineer the proprietary Samsung VoLTE implementation.
[OFFICIAL] LineageOS 18.1 for the Samsung Galaxy S4 (All QCOM Variants)
- Thread starter npjohnson
- Start date
I have here in germany running Aldi-Talk (O2 ?) the option to switch to 4G (LTE, what should be the "LTE-only"), 3G (UMTS, should be dead) and 2G (GSM) on LineageOS 18.1.
it might be that it's mobile provider dependend.
anyone else from Poland here running T-Mobile to clear this point ?
But, I'm currious that T-Mobile had switched off 2G too, cause that would exclude all phones which are only able to run 2G...
I'm also curious if LOS could do VolTe at all.
anyone ?
and if not:
I guess it won't come, cause development for S4 is nearly dead and I further guess there will be no LOS anymore for the S4 when LOS 18.1 is at it's support end (when LOS 20.x goes online, May (?) 2023)
means: there is no "You have to ..." and there had never been such thing (for an OS for free) !
the last stock for an S4 is Android 5.0.1:

what hold you off to run the phone with stock /buy another phone ?
last question:
why are you able to switch to 3G when you said before it's offline ???
me is confused.

VoLTE will never work on the S4, or the S5.
These are from early VoLTE generations - in which there was no even semi-standard method to do it. Samsung and LG both stuffed it into the frameworks side java code and it's hopeless - there are too many subsystems working together on the stock ROM we just can't reverse engineer and tie together on LineageOS.

You could check out the extensive guides from @Retrial. These contain hints for troubleshooting, too.
S4 Unified Collection & Guides
1. Is there any way to add "LTE ONLY"?
2. Is there a chance to fix the option of a faster return to the 4G network?
Just these two points don't work! The rest of the software is great 100% ok!
Additional questions:
Why is there no bandwidth enforcement on Lineagos?
Such options were already available in good E3372 modems 7 years ago (the famous Huawei HiLink).
Lineageos should be more extensive in this respect.
There should be manual sorting of the bands: LTE2600, LTE2300, LTE1800, 800, 900 and so on. It would be a great thing.
Other deficiencies in LineagOS include:
1.no possibility of automatic (scheduled) turning on and off the phone at certain times (times of the day)
2. the inability to set the PROFILE (silent, home, offline, loud) at specific times (times of the day) - scheduled times and automatic start.
3. Call recording does not work on all versions of the system.
4. Unfinished screenshots (rough controls)

Can you please send me instructions on how to install the latest baseband version?
The current baseband version is: I9505XXUHPK2
I have installed the gapps "MindTheGapps-11.0.0-arm-20220224_161620.zip" and nothing from magisk.
Which gapps version is the best for the S4?
Kind regards

Data transmission does not work with the latest software version. Despite the switched on transmission (both in 3G and LTE networks), all applications will say: you are not connected to the Internet. There is still no "LTE only" option in the latest firmware version. I'm going back to stock-soft, it doesn't make sense. It cannot be used, just as underdone as almost all Cyanogenmods. Let's skip VoLTE, but the "LTE ONLY" option should be. I also see no obstacles for Lineageos to have icons on the desktop for fast network switching (with one click) as standard in such cases, eg "2G ONLY" "3G ONLY" "4G ONLY". This would solve almost all problems because the USSD and SMS codes work in 4G, there is only no telephoning when there is no VoLTE option. Meanwhile, this software cannot be used only for the Internet! Why are developers having trouble adding an option to force bandwidth in 2022? Why is there no "ONLY 4G" and "ONLY LTE2600" options? I also inform that the i9505 model cannot be loaded with earlier versions of Lineage, e.g. v13 (Android 13). The message in recovery says: the uploaded software is only for the model (and here it lists available models) and the list of models listed is the one I am trying to upload soft to. The hands drop.
PS. T-MOBILE Polska in the official announcement of November 2021 announced that it will turn off the 3G network, but it does not plan to turn off 2G for the next 10 years. The reason is that disabling 2G would cut 40% of Poland from GSM telephony coverage (3G and 4G have a lot of holes) and cut off older people from the phone. We would go back to the times before GSM. GPS locators in car fleets, alarm systems, remote access and home management (GPRS) are based on GSM. Disabling the 2G 900/1800 network will paralyze the country!

Introduction:
This is the Official Lineage OS 18.1 thread for all Galaxy S4 variants.
Downloads:
Please follow the install instructions in your device's Wiki page linked below exactly, and make sure your device's firmware matches the required firmware listed.
- jactivelte (GT-I9295)
- jflteatt (SGH-I337) - Please note you will need to be on bootloader I337UCUAMDB or I337UCUAMDL
- jfltespr (SCH-R970/C/X, SPH-L720)
- jfltevzw (SCH-I545) - Please note you need to be on bootloader I545VRUSMDK
- jfltexx (GT-I9505, SGH-I337M, SGH-M919) - NOTE: GT-I9505G is supported in this build, but due to system size space limitations it will not fit any form of GApps package.
- jfvelte (GT-I9515/L)
If you don't follow these instructions, or use 3rd party add-ons (like Magisk) please don't expect support here.
Known Bugs:
- MHL doesn't work after LineageOS 14.1, and likely never will again, as Google dropped support for it platform-wide in AOSP.
- Find any? Report them according to this guide.
- The only supported GApps package at the moment is MindTheGapps, linked on our Wiki page about gapps.
13As @npjohnson said...even my builds seems to work fine, they simply "bypass" some new, Android 12 stuff because our old device can't support.
Go to data usage, via settings, and check any application data usage. Let's say Chrome. Regardless how much u use the Chrome, the data usage seems zero. That's the problem.
I personally consider and respect the fact that lineageos wouldn't ship a build which includes a hacky thing that bypasses those network related stuff. This feature is a big change on Android platform, hence, I understand why LineageOS insist on a fix on this
tl;dr, as nolen said, the problem is on the kernel side and since jf can't have that backported change (I won't mess with it personally), the solutions are 2.
1. Someone will mess with jf kernel and will backport ebpf (as lineage page says so)
2. We will restore iptables back. This is my approach and I will personally work on it too. Fixing this will help many legacy device come back but trust me... It's really hard to bring it back7VoLTE will never work on the S4, or the S5.

Samsung and LG both stuffed it into the frameworks side java code and it's hopeless - there are too many subsystems working together on the stock ROM we just can't reverse engineer and tie together on LineageOS.6
This issue is now fixed. You will need to sideload the upcoming build by hand to get back on track though.
Sorry for the inconveniences.6
Side is one of us. He's aware of the constraints lol.
It's not "strict" - the "workaround" people keep linking LITERALLY just ignores the error - data restrictions, data management, and routing in general will always be 100% broken - and that will never be considered "working" - if someone makes that stuff properly work, even if tacky, we're no opposed - just that the current stuff isn't even a hack, it's just "ignore what's broken".
