Flash your stock ROM, boot and check if Bluetooth is working. If yes then flash twrp and make a backup of EFS. Then clean flash LOS and check if Bluetooth is working. If not restore EFS on twrp. If it's still not working, read the posts in this thread #411 and further
[Galaxy S3 Neo Original Android Development] helloyello:
Thanks, I read some of the latest posts in that thread and learned that it's not really stable/working good on LOS16. I don't want to mess up my LOS16 installation, can survive with the official Trebuchet 9 UI.

OTA update 08.03.2020 - lineage-16.0-20200308-nightly-s3ve3gxx-signed.zip

I performed my first OTA update with the LOS16 updater app (setting menu) since I started using LOS16, original image I used was: lineage-16.0-20200219-nightly-s3ve3gxx-signed.zip and got into some issues.

- I started the updater - download the 08.03.2020 nightly image with 75% battery, it finished in less than 5 minutes

- clicked on INSTALL and waited until the new image was automatically flashed (TWRP)

- on the first reboot after the update I got 51% battery left and launched ViPER4Android FX 2.7 to check if the driver was preserved. Negative, the ViPER4Android FX 2.7 app warned me that the driver is not available anymore and asked me if I want to reinstall it. I accepted, it did install the driver automatically and rebooted.

- while still on 51% battery, I checked the GPS functionality with GPS Status & Toolbox for about 5-10 minutes. LOS GPS setting was configured on "Device Only"

https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2&hl=en

- while waiting for a GPS fix, I realized that I never performed an A-GPS update in GPS Status & Toolbox, pressed the home button, got into AFWall+ to allow the GPS Status & Toolbox on the internet (WiFi was off!) and the phone froze while in the AFWall+ list of apps

- I had to power it down - kept the power button pressed for a few seconds and started the phone again fresh, just to get a warning that my battery is at 14%

I'm restoring the backup I did for the lineage-16.0-20200219-nightly-s3ve3gxx-signed.zip, that image worked well for over two weeks now.

Edit --------

Some screenshots. I started to charge the battery while still under the 08.03.2020 nightly image, just to prepare it for the restore process and realized that it has charged the battery 30% in less than 10 minutes.

LOS16 - 30% in less than 10 minutes - (clock is wrong - 1 hour later - don't mind it)

Edit 2 -------

Wow! It charged the battery at 90% while I was writing the section above - less than 10 minutes and it was connected to the laptop USB port - 500mA instead of original power adapter 1500mA. Something is really wrong with this image (or the images after 20200219).
[Galaxy S3 Neo Original Android Development] Humaxxx:
Hi. I use this ported trebuchet launcher on my two S4s ( don't really use these phones) and my S3Neo, since years and never faced problems which i think they are related to the launcher.

I never used Viper4Android, but normally installed apps will survive ota-update except you "installed" it as a system-app.

I am on 2020-03-04 and there are a lot of updates / changes after that date. Changelog . Maybe there has gone something wrong. I wil update now and see what happens.

--EDIT--

Updated now to 2020-03-09. Start Update 20.10 o'clock with 56%. Update was finished at 20.13 o clock. Battery is at 54%. So looking good so far.

--Edit2--

Connecting to PC (USB) its charging (slowly) with about 300mA, 1,4W
[Galaxy S3 Neo Original Android Development] helloyello:
Thanks for sharing the experience with the ported Trebuchet Launcher, I believe I can live with the one on LOSS16, got used with its ugliness :)

Viper4Android is installing some drivers that I lost during the OTA, it was only the drivers, not the App.

Indeed, I noticed there were a lot of changes lately in LOS16 and that's why I considered to perform an OTA. Frankly, I hoped that the Hidden WiFi and the power on delay (50 seconds) issues were addressed.

I'm on s3ve3gxx - Sony Camera, and I'll perform again an OTA if you can confirm (again :) )that everything is working fine with your 2020-03-09 update.

Thanks!
[Galaxy S3 Neo Original Android Development] Humaxxx:
I am stil on the build from 2020-03-09. No problems for me so far, but i didn't used my phone much these days...

Maybe you can set up an "survival" script, which is triggered when an flash is performed. That script can copy files, if this is enough.

IF pictures are stored on SD card they're saved under android/data/org.lineageos.SNAP/files . Is there a way to change it to sth like /DCIM?

Another problem US with ScummVM - it doesn't see structure od catalogs on SD card too.
[Galaxy S3 Neo Original Android Development] Humaxxx:
No way to change it manually. It's the new storage path, which was needed to change in Android 9.
[Galaxy S3 Neo Original Android Development] Aufhellblitz:
Perhaps with a link from /storage/XXXX-XXXX/android/data/org.lineageos.snap/files

to

/storage/XXXX-XXXX/DCIM/Camera

So with ln -s as root. but rename it first (/../org.lineageos.snap/files)

hello,

anyone tell me how to update my latest bootloder and modem without pc on i9300i

sms (receive and send ) problem so
[Galaxy S3 Neo Original Android Development] Humaxxx:
You can try flashfire or mobile odin
[Galaxy S3 Neo Original Android Development] Sagunflo:
oky thanks brother, i install flashfire and download offical farmware for i9300i , file named (I9300IDDUBPF1_I9300IODDBPF1_I9300IXXUBOJ1_HOME.tar.md5) is this file to flash or iam wrong?
[Galaxy S3 Neo Original Android Development] Humaxxx:
Whats your current baseband and bootloader?

Last free letters gives you the date of your firmware (I9300IDDUBPF1_I9300IODDBPF1_I9300IXXUBOJ1) (PF1 / OJ1). So i would prefer to use a newer one like this

For mobile odin or flashfire you need root and if the app closes you need to set back date!
[Galaxy S3 Neo Original Android Development] Sagunflo:
finally download waiting hours..

but here bootloder option is not ticked and i dont know about other partition options,
[Galaxy S3 Neo Original Android Development] Humaxxx:
You can google for "I9300IZHSBQB1" to find faster download.

I never used mobile odin or flashfire, but you should read the description of both apps. one is for older phones, one for newer?!

Hi all,

I'am looking for a bug free ROM for my Samsung.

Model Galaxy S3 NEO DUAL SIM (GT-I9300I) .

At the moment i'am using Android 5.1.1, 12.1-20171126-UNOFFICIAL-s3ve3g.

Newer bug free version available for my DUAl SIM phone?
[Galaxy S3 Neo Original Android Development] Humaxxx:
All custom roms for S3Neo has bugs, also your version (i guess its CM12.1) you are just using!

It always depends on wich bugs you can life with...
[Galaxy S3 Neo Original Android Development] mariocaraf:
cm 12.1 has no bugs, it is obsolete, this is ....
[Galaxy S3 Neo Original Android Development] Humaxxx:
I have used cm12.1 for several years, also newest version from 2017-12-25. In my opinion the stablest custom rom, but it has definitely bugs, such as:

1) No NFC

2) No emergency call possible!

3) no deep sleep after charging
[Galaxy S3 Neo Original Android Development] mariocaraf:
los 16 has nfc? no rom has nfc, emergency calls? the stock rom is customized by country, and has emergency calls, the custom roms are universal and each country has its own numbers!, i am with los 16 for magisk hide, but 12.1 cm is and has always been the best!, deep sleep? if you use it as it is, ok, it doesn't bother me, but los 16 consumes me twice the battery, I use 2 s3 neo, one with los 16, and one with 12.1 cm, and I see the differences, and I'm a geek.

I use phones with the same apps!

but los at the end is ok.

nightly, it means beta, right?
[Galaxy S3 Neo Original Android Development] kurtn:
Nightly is the most stabile you can get from lineageOS. But it depends on the time of year. 16.0 is really stable now. With a fresh released 17.1, more bugs are to be expected.
[Galaxy S3 Neo Original Android Development] Humaxxx:
You said cm12.1 has no bugs and that's not correct!

NFC doesn't work on S3Neo on all custom ROMs, but that's a bug for me. And a major bug is when emergency call is not working! Emergency call has to work also on custom rom and it works on other devices and also on LOS16 for S3Neo, so it's a bug!

And even if cm12.1 has better battery life for you than on Los 16, it's still a bug when deep sleep is not working correct!

Nightly is not beta. Nightly is official stable build which comes every night with updates. Official cm12.1 was also nightly!

Error: Bluetooh keeps stooping

Help
[Galaxy S3 Neo Original Android Development] Humaxxx:
Restore your EFS in twrp. If you don't have made a backup of EFS, restore a working backup of a rom and backup EFS and then restore LOS16 and then EFS. If you also don't have a working backup of a custom rom. Flash stock rom, boot up and see if Bluetooth working again. If so backup EFS then do a clean flash of LOS16.
[Galaxy S3 Neo Original Android Development] Merftj:
See the bluetooth settings in the attached image...
[Galaxy S3 Neo Original Android Development] Humaxxx:
Not available is normal if bluetooth is deactivated!
[Galaxy S3 Neo Original Android Development] Merftj:
I restored the EFS backup, but it didn't work. With the original ROM it works.
[Galaxy S3 Neo Original Android Development] Humaxxx:
So you flashed back your Stock Rom and there Bluetooth is working. Thats a good news for you!

After Stock Rom you should do a clean flash of LOS16. But before that check if your bootloader and baseband is up to date.

Please answer these questions

- Whats your model? GT-I9300I or GT-I9301I

- Whats your baseband

- Whats your bootloader
[Galaxy S3 Neo Original Android Development] Humaxxx:
I dont recommend to use any other camera app than the stock one on S3Neo with LOS16. Because any other app i tested will always give you white line in recorded videos, when you pivot around.

I will report Bluetooth issue to devs
[Galaxy S3 Neo Original Android Development] Alastor89:
Hi, I'll try to post a boot.img with some kernel commits reverted in the following days in order to try to workaround this bt issue. It is a bit hard to reproduce it for me as I do not do call for so much time on bt usually.

Thanks for the feedback with recording movies. Frankly, I never record movies but only take pictures ... I remember I couldn't configure the default stock Camera App to store the pictures on the SD Card and that's why I switched to Open Camera App.

General Question about LOS16 on S3Neo and OTG.

On stock ROM I used NeOTG to enable USB OTG, unfortunately it doesn't work anymore on LOS16, the application just hangs after providing root access :(

https://xdaforums.com/android/software-hacking/neotg-otg-enabler-t3556605

Is there any other way, maybe somewhere in the LOS16 settings where I could enable OTG? Or any other App like NeOTG that works on LOS16 ?

Thanks in advance for any help.
[Galaxy S3 Neo Original Android Development] Humaxxx:
USB OTG should work with this. If Not just give feedback to me

With Stock Cam App you can simply switch to sd card, but since los 16 the Path is no more sdcard/dcim. Its "SDcard/Android/Data/Org.Lineageos.snap/files"
[Galaxy S3 Neo Original Android Development] helloyello:
Thanks! It works now with that OTG Enabler APK, although it mounts two devices - that's what I could observe in Total Commander. I'm able to access them both in RW mode.

On the LOS16 kernel for S3Neo, I was googling around trying to find the source code for the kernel and have a look at the changes, but failed so far. I only found:

https://github.com/LineageOS/android_device_samsung_s3ve3gxx

But that's not the kernel ... wondering if the kernel source and changes (commits) are publicly available?
[Galaxy S3 Neo Original Android Development] kurtn:
https://github.com/LineageOS/android_kernel_samsung_msm8226/tree/lineage-16.0?files=1

The kernel is Linux under gnu licence. Everyone who distributes software under that licence is forced to publish the source code.
[Galaxy S3 Neo Original Android Development] helloyello:
I know that, I just don't know too much about LOS development and the repos that are available for public, discovering and learning it now.

Thanks for the link! TBH, I searched after "lineageos msm8226 kernel" in google and only stumbled upon some Motorola stuff & some other SoCs ... :rolleyes:

WiFi problem

Disconnects when downloading WiFi connection and reconnects after a while.
[Galaxy S3 Neo Original Android Development] Humaxxx:
Can you explain better? Maybe your distance to router is "critical" and looses connection a short time?
[Galaxy S3 Neo Original Android Development] mariocaraf:
will be the router, I don't have this problem
[Galaxy S3 Neo Original Android Development] daniiel:
For example, when I'm calling in Whatsapp, the Wi-Fi connection will be lost after a few seconds And reconnects And it makes the call lost.

or in Instagram sometimes When watching movies This problem happens, That was not the case in the offiical ROM,

But interestingly, this problem does not occur elsewhere like the Clash of clans game or when WiFi is just standby!

And let's just say I'm very close to the modem and the modem is okay.
[Galaxy S3 Neo Original Android Development] Humaxxx:
on which build(date) are you? Since when happens that to you?

With official rom you mean stock rom ?

what can i do for usb otg on lineageos 16
[Galaxy S3 Neo Original Android Development] daniiel:
Latest version of LineageOs16 (March 25, 2020),I've always had this problem with all versions of LineageOS 16 , yes I mean stock rom
[Galaxy S3 Neo Original Android Development] Humaxxx:
Hmm, ist your baseband / bootloader up to date?

Whats your model GT-I9300I or GT-I9301I
[Galaxy S3 Neo Original Android Development] daniiel:
my baseband is I9300IXXUBPF2, my device model is I9300i (s3ve3gds)
[Galaxy S3 Neo Original Android Development] Humaxxx:
So you have Stock Rom from June/2016. Maybe thats too old!

I would recommend to do the following steps and then test again if then wifi connectiong is more stable (but i cannot promise).

1) Boot into twrp(recovery)

2) Make a Backup (System/Data/Boot)

2a) make a backup of efs (if you didn't before)

3) Download and flash the Stock Rom from 02/2017 from here or here and flash it via odin until your baseband / bootloader has updated (this sometimes need to be done more than one or two times) .

4) Flash latest twrp via odin

5) do a full wipe

6) Restore your LOS backup

When was the last time you updated the ROM? In March there were added some patches which at least doubled the standby time on my S3-Neo.

Even on the original ROM (KitKat) I hardly reached 4 days of standby (offline). Now I'm able to get up to 9 days of standby.

[Galaxy S3 Neo Original Android Development] helloyello:
Well, the so called workaround, activating the "Unrestricted data usage" for the Phone app didn't work, I still got the BT loosing audio after 43 minutes. I bought a new Plantronics BT Headset (cheapest one) and it works fine, no interruptions. So my theory is that it could be something related to older BT protocol standards, as both Nokia BT Headsets I used were very old, 10 & 6 years ... I just don't understand why it happens only in the Phone App. For the messenger apps, where the reported interruption doesn't occur, I'm 99% of the time connected on WiFi, and maybe having both BT&WiFi activated (same IC) makes the audio BT system stable .. :confused:

---------- Post added at 10:43 PM ---------- Previous post was at 10:32 PM ----------

I'm running:

lineage-16.0-20200310-nightly-s3ve3gxx-signed.zip

My Stock ROM was heavily "cleansed", around 200 system apps removed and Greenify was taking care about the rest of the useless crap.

I'm not talking about the standby time in LOS16, but the actual use time. In the screenshot you presented, I noticed that you've used the screen for 2,41 Hours and the battery consumption for that was 7%. I'm wondering, are you keeping the screen on minimum brightness all the time? Or maybe you're not using the phone outside in the sun too much ...

I'm on auto-brightness and there is a pretty dumb implementation I noticed on LOS16. When turning on the screen it always starts on maximum brightness and then auto-adjusts it to the environment. Why? You get blinded by the maximum brightness and it also consumes a lot of battery. On stock ROM it remembers the last brightness level and adjusts from there. I mean, even if the functionality of the Stock ROM cannot be implemented, at least start with the lowest brightness and adjust it upwards, instead of the actual dumb implementation maximum first and then adjusting.

___________________________________________________________________________________

I had a general functionality question I forgot to ask about LOS16 on S3 Neo.

I've noticed that LOS16 supports Screen Cast - I have an Icon for that in the tiles menu.

On Stock ROM there was no such functionality and I remember reading that the original S3 (not the Neo) had Screen Cast and that Samsung disabled it in the S3 Neo. Was always wondering if there is also something HW related.

Today I tried to connect (cast) with a Samsung Smart TV and failed. I turned on WiFi, disabled the firewall (afwall+) and clicked on the Cast icon. It started searching and couldn't find the TV. I was able to cast from a Samsung tablet to this TV, so the TV and local WiFi LAN looks OK.

Wondering if any of you have used the Cast successfully in LOS16 on S3 Neo?
[Galaxy S3 Neo Original Android Development] Humaxxx:
About your bluetooth problem, i can't answer, because i dont use "bluetooth-calling". Best chance for you is to directly talk with devs.

About screen on time (sot). For me, i get about 5 hours of using my Neo with LOS16 with max cpu 1190mhz, before i have to charge again. With Stock Rom (without greenifying apps) it was much less time.

I am not 100% sure what you are trying to do. Is there a build-in app for casting TV and Neo? Or are you using a third-party-app.

So if you want to play a video from your S3Neo on your Samsung TV it should be possible using an app from Playstore. I tried that for short a few months ago. I have a Samsung TV (7 series) and used this app.
[Galaxy S3 Neo Original Android Development] helloyello:
I just updated the Bluetooth Issue with my latest observations because one Dev was already trying to fix it - see post #691

https://xdaforums.com/showpost.php?p=82120657&postcount=691

You don't need a third party app to cast the screen from an Android device (past Android 5 - Lollipop):

https://support.google.com/chromecast/answer/6059461?hl=en

The problem with LOS16 on S3 Neo is that when I activate the CastScreen (Icon) from the Tiles Menu, it starts scanning the available devices and cannot find my Smart TV.
[Galaxy S3 Neo Original Android Development] Humaxxx:
Did he make you a new boot.img as he told for testing Bluetooth or did he forget it?

I am at work now. I can test the build-in cast function, when I am at home. But at least it's possible with a app.
[Galaxy S3 Neo Original Android Development] helloyello:
Nope, he didn't provide an updated boot.img. Don't know if he forgot or just got disinterested :)

On the screen cast function, there could be some other underlying issues. I can't find any WiFi Direct or Wireless Display settings and maybe these are not implemented in LOS16 ... here's a bug report for another device:

https://gitlab.com/LineageOS/issues/android/issues/1312
[Galaxy S3 Neo Original Android Development] Humaxxx:
I again talked to dev. He will try to make a boot.img for you the next days. Here is his message:

that stuff would be very hard to debug if that is true.I mean that is theory is probably true.

But I do not have 10 years old bt headset.

I will provide him boot.img btw in the following days
[Galaxy S3 Neo Original Android Development] helloyello:
Hey, thanks for the "Mühe". I already reported that I bought a new Plantronics BT Headset, some newer bluetooth standard and it works fine.

Please tell the dev to not waste time on this anymore. It was also time for me to buy a new bluetooth headset, although the 6 years old Nokia BH-108 was still OK, the battery lasted 4-5 hours.

I'd rather focus on the Cast Screen / WiFi Display / WiFi Direct instead.;)
