Hi,

here you can find my version of LineageOS 19.1 for our Samsung Galaxy S3 (I9305).

This is a beta build, also from the LineageOS side, there are typical functions still missing, so don't install it if you want a completely stable and completed ROM and don't report my already listet bugs!

Attention:

Sometimes it needs another reboot to find the sim card.

When you have BitGapps installed, you have to reflash them after every update!

Here you can see how far everything is working for now.

  • Boot
  • Audio
  • Bluetooth
  • Graphics
  • Cameras
  • Sensors
  • Wifi
  • GPS
  • USB
  • Video playback (HW/SW)
  • Tethering via USB
  • RIL
  • OTA-Updates
  • Tethering via WIFI and Bluetooth
  • much more...
  • Random reboots
  • NFC
  • SD-Card can't be formatted as internal storage, this will cause a bootloop
You could use a gps.conf from https://app.box.com/s/w57s1v1n3hie7l5lk28i for your location and replace /vendor/etc/gps.conf.
Or you try GPS Server Optimizer app for a faster 3D fix.
For both methods you need root rights.
I would recommend to use microG instead of BitGapps,
here you can find the installation instructions:
  1. Download Magisk 24.1 and flash it via TWRP (yes, flash the APK file), reboot
  2. Open Magisk and update the App (and do a reboot if it's asking)
  3. Enable Zygisk in Magisk
  4. Download and install microG installer in the Magisk manager, reboot
  5. Download and install safetynet-fix in the Magisk manager, reboot
  6. Check with a safetynet checker app and you should pass :)

Do you like my work?
Than you can simply hit the thanks button and consider to spend me a coffee or a beer,
I'm doing this in my free time and it also costs a lot of money to buy hardware.

donate

Wanna improve your sound configs, control your charging current and more?
Now you can use my app to access all boeffla configurations, there will follow more functions.

Update 08.03.2022:
  • Synched with latest LineageOS sources
Thank you for the great job. Having 12 on our old SIII is amazing ! Have now a very limited use of this device with Build 0215 - but works like charm. Although tech is old, transitions and speed are more than acceptable, ...

Have tried update OTA but ended in bootloop on LOS logo.
Tried a clean install with 0308 build same bootloop.
Tried Magisk - stuck on Samsung logo

Restored build 0215 :) :giggle: (y)(y)

Did you have older bitgapps installed?
(If yes, you would have to reflash them)

It's hard to say why you're facing a bootloop, it did really work fine on my testing device.
I use my SIII gappless, same with my S5. => I ota over 0215 gappless !
Then I did several attempt: after full format:
- restore build 0215 + flash Magisk + Bitgapp didn't work
- flash build 0308 + Magisk 24.2 or 21.4 didn't work
- flash build 0308 + Bitgapp for 12 didn't work
- flash build 0308 + MindTheGapp for 12 didn't work

So far, its fine with 0215 for my limited use (no tel, no text, no mail client, few use of internet browser, few specific Apps installed: SDMaid, AllToolinONE, Mixplorer, MusicSpeedChanger. Except Mixplorer where I noticed some laggy transitions, the other apps work fine.

Sorry I did'nt logcat fo you :confused:

Update 25.03.2022:
  • Synced with latest LineageOS sources
  • Created possibility to disable the HW navigation keys (not really needed for full gesture navigation)
  • Fixed boot problem, which mostly appeared after booting from TWRP
  • Fixed shutdown bug (device restarted sometimes instead)
Great job (y)(y):love:
OTA update done like a charm 😊
HW keys disable is good as I use navigation bar
Will see for the 2 last item …

On previous version 0317, I succedded to flash magisk 24.3 but didn't work properly - device became very laggy or stuck, the permissions granted didn't stay, therefore I removed it (n)

    Update 04.04.2022:
    • Re-Implemented and enabled boeffla sound
    4
    So far are the results of my tests...

    What I have tested and is working :
    • Audio calls
    • SMS / MMS
    • Camera
    • Speakers and microphone (tried with voice recorder at this time)
    • Wifi and mobile data (but there are some problems - see below)
    • USB connection with PC (ADB + MTP)
    • Nearby share
    • Screenshots
    • Sound and micro are good under most of use cases (headset, handset, speakers etc...) : I used to deal with sound and mic problems with previous version of Lineage (14 then 18), but now it seems to be better in this rom, congratulations :)
    • Screen split mode works only by swiping up (to view running apps) then clicking on an app logo / "display at top".

    What is not working :
    • Device become laggy after a while (until it become unusable at all)
    • Strange behaviour with network connection at the first days of use : sometimes I have to disable wifi and rely only on mobile data, sometimes I have to enable WI-FI to make an app working with internet... and sometimes, for a given use case at two different times, the solution can differ (either enable o disable WI-FI)... EDIT 28/04/2022 : now this problem doesn't seem to exist anyore, very weird because I changed nothing...
    • Settings in the gallery app (blank screen)
    • Adding contacts to the emergency settings (yes I know, it is not a high priority bug...)
    • Screen split mode by tile shortcut (via swipe down)
    • Bluetooth with car : pairing is OK but no sound and no microphone... and after that there is no sound anymore for any call even without bluetooth : no other way than rebooting :( After some minutes of bluetooth pairing, phone begins to be very laggy, too.
    • Bluetooth with headset : pairing ok but sound/microphone sound is very very low.
    • The "type your sim code" screen is VERY slow to come. You sometimes have to wait for one or two minutes after unlocking before this screen is shown. At the beginning, I thought it was a problem with sim recognition.
    • GPS fix is pretty bad - much more than my other i9305 with LOS 18.1. Tried with some other gps.conf, just a little better but still not as good as my other i9305. Didn't tried yet with the app pointed by @html6405 in this post.

    I haven't experienced random reboot, afaic

    Some problem above make this rom unsable in real life, for me. Lineage 18.1 is much much more usable at this time.
    I am going to test the new Lineage 18.1, update 20.04.2022. EDIT 28/04/2022 : I resumed trying yesterday to test this device with this rom, and it is weird because now the phone is nearly usable in real ife : no connection problem and the phone become laggy after hours (less than a day, though) - except if I make a bluetooth pairing (lags come quickly in this case and blutooth is not functional anyway).

    Here is a last_kmsg file, after a reboot I had to do because of heavy slowdown... but there were NO crash, so I don't know if this file will worth an analysis. Moreover, for this session, I removed the sim and sd card to check if it could be related to the lags (and it is not, at last).
    I tried with different batteries (I tried the one used for my other device with Lineage 18, which works fine), for no change.

    Please note that I haven't installed Magisk (device is not rooted).

    Have a good day !
