Do not block wakelocks. That can lead to massive power drain.

The Greenify app is really good at putting apps to sleep safely.

The phone will need a couple of full charge cycles before it reports true battery percentage/drop. This is the same on stock.

Use better battery stats to work out what is keeping your phone awake.

I noticed a "no deepsleep" issue after unplugging my charger sometimes. Please test the following - charge - unplug - reboot - and see if your device goes in deepsleep now.

Additional info about my config, usage, etc :

* GApps Super installed

* Magisk v20.1

* Magisk module ACC by [MENTION=5228676]VR25[/MENTION] ( advanced charging controller ) stopped charging @ 89% , continue charging @ 82 % , helpful f.i. for the health of the battery during navigation

* Magisk module Universal GMS Doze 1.7.3 Beta 6.1

* Naptime

* SIM inserted ( it's my "business-device" )

* WiFi, BT, mobile data, location ALLWAYS on ( using it as navigation device )

* Ok Google hotword enabled and active

* Bought a new NFC accu 2 months ago - this thing is incredible, was a very good idea - from Akku-King, not a "original" ( it's ALL fake ! ! ! ) Samsung accu.

Hello !

One short question.

Update from RR v6.2.0 to this LineageOS

Factory reset and flash ? Thats all what should I do ?
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] danwood76:
Wipe system/cache and format data.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Neoony:

[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] 0LDST4R:
Exactly this one. With NFC. You won't regret it. :good:
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] nanquan:
When using the Quick Settings from the lock screen, if you try to toggle "Mobile Data" the OS prompts you to enter your credentials (pattern, password etc.).

Is there any way to duplicate this behavior to other settings, such as: Airplane mode, Location, Wi-Fi etc. ?

Whatever that may be, either a Magisk module, EdXposed, direct flashing of some patch via recovery, you name it... any way that this can be achieved?
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Neoony:
Maybe some of this helps?

Thanks for trying to help, but I already looked over those and it's not really what I'm looking for.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] pled:
Hello,

I helping a friend to "rebrand" his Samsung S5 Neo (s5neolte) and we have installed latest lineageos build (official) lineage-16.0-20200419-nightly-s5neolte-signed.zip + MindTheGapps-9.0.0-arm-20190615_031401.zip (seems to be recommended for Samsung models).

He is now experiencing issues with MMS, although APN has been double checked. He can't send or receive MMS, when sending, it stays in "sending in progress", and when receiving it stays in "downloading" (translated from french, so this is not the exact message). He found that stopping application from parameters-apps menu, it was working again, but just for a while, it stops working again later on.

Has anyone any idea what's going on here ? Should he reinstall Lineageos (same version ?) and GApps (same package ?).

Thank you for your answers.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] pled:
APN issue

Replying to myslef : That was a APN configuration issue indeed. After a 2 hours chat with support, we finally got it to work, ending with "reset to default", shutdown, remove SIM, insert SIM, restart.

That may help someone else !
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] nanquan:
Just out of curiosity, but why is your friend using MMS in this day and age?
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] pled:
Because we are both coming from that "good old time" ! :D

Added to that, he is using WhatsApp, I am using Signal, I cannot ask him to install Signal (aka only for me), and I will never install WhatsApp on my phone (no Facebook no Google, etc...). MMS is still kind of standard, installed by default on every phone.

why lineageOS 16 FAIL to install instead lineageOS 15 is ok ?

hi all, i'm trying to install this rom, but something goes wrong.

I boot in twrp recovery 3.3.1-0, i do a full wipe, then install lineageOS 16 (9.0) rom.

I do a reboot, the phone begin to boot, i see the lineageOS picture and after some minutes the phone return to recovery.

Someone has suggestion?

Note:

If i try to install lineageOS 17 (10.0) rom it fail, instead

If i do the same with lineageOS 15 (8.1) rom i'm able to install it and the phone start normally.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] cggraciel:
Wipe cache, dalvik, system, data, etc, them install the ROM, if that doesn't work, download the ROM again. Finally install gaps if you like It.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] gpl.lag:
Finally i success installed this rom, but something goes wrong with root.

The phone start normally, but when i flash "addonsu-16.0-arm-signed.zip" it seems no rooot happen (seen using root checker).

Is the right su package what i'm using ?
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] jackstef:
Flash Magisk
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] gpl.lag:
Does magisk modify my recovery ?

Because i have another rom and it's already rooted, if magisk do something It doesn't work at all.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] cggraciel:
Magisk is the best option,
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] danwood76:
Magisk modifies the boot image. You get a systemless root which saves you a million headaches. Only your current ROM should use that boot image so you should be fine.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Neoony:
Did something happen with LineageOS updates for S5 Neo?

Last update is 19th April.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] gpl.lag:
All was ok. I rooted LineageOS with magisk and it works.

After i tryied to restore my previous Nandroid backup with success.

So i'm table to use boh versions.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] 0LDST4R:

I guess they still didnt recover since then?

Now that I see the status you posted, it seems its down since then.

Anyways its apparently because of some issue:

Interesting. I never knew that.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] nanquan:
I need a small favor :D

I really liked the charging sound in LineageOS 16. But they removed it completely in LineageOS 17.1, and replaced it with a different sound.

Could someone please post the sound file for LineageOS 16's default charging sound so that I could download it? Or at least tell me what it's called? ?

Hey guys. Does anyone happen to have or know where i can get a copy of the 16.0 rom in 2023? I have an old app that only works in android 9. I've looked all over but can only find 17.1 or newer for the S5 Neo.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Neoony:
hmm I checked my old files

I only have

14.1

15.1

17.1

18.1

19.1

I guess I missed that one
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] blob101:
Wow 14.1 is impressive. I didn't know they went back that far. Its a shame there is no achieve for the old roms. Lineage only keeps them from 2020 onward, so i imagine a lot of the older versions have been lost.

If i find 16, ill let you know so you can complete the collection lol.

Just installed the 20190729 update and the wakeup issue did not occur after the update. Thank you [MENTION=8184192]Stricted[/MENTION].
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] i7i5:
Hello,

I'm a silent reader who follows the "lineage on s5 neo" topic since the start of developement of the laOs 15 s5 neo version. Tanks a lot for your work [MENTION=8184192]Stricted[/MENTION].

The first img I installed on my neo was the 20190707 build and it worked surprisingly good on my phone. I did a clean flash wiping the whole phone with help of the newest twrp. I had almost zero issues with this build.

No lagging, no battery drain nor bluetooth problems, camera and sound working. Sometimes the ui crashed or the phone lost the wifi connection while in standby. I got the wakeup problem very rarely. I think it's caused by having wifi connected while the phone is in standby. - I use this phone as my daily driver and it simply works!

The day before yesterday I did a dirty flash to install the latest build (20190729), means that I wiped the caches and installed the latest zip. On my phone it was very laggy experience, typing smth. with the keybord, app behavior, almost everything. Yesterday I flashed back to the mentioned 20190707 build and everything works smoothly again.

Is there smth. I might did wrong updating to the newest version?
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] glallier:
Thanks for your great work [MENTION=8184192]Stricted[/MENTION]. I had the exact same experience as [MENTION=6572494]i7i5[/MENTION]. LOS 16 20190707 build was the best for me, compared to latest one and LOS 15.1 builds.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] afortaleza:
I am facing the same problem, did a dirty flash to 20190729 and even though it has fixed the wakeup issue the whole system is laggy. I've tried to remove animations but it's still very slow. Thinking about reverting it back to 20190707.

Anderson
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Stricted:
the lag problem will be fixed with the next build

im waiting a few days until the august security patch is merged and will post a new build then
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Juuppi:
I reverted today and been so happy to have the performance, although I have some small problems with wifi on 20190707. Looking forward to update to the new version OP promised to publish soon!
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] JMek:
I tried the latest and:

Dirty flash: Went all laggy and weird.

Clean Flash: Seems normal or at least drastically better than the first try.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] ebbos:
first: bye bye awake bug.

dirty flash one week:

so laggy apps in the first day, the next days, all perfect.

proccess in background are closed, for example music player (stops the music) and chat apps (don't receive any notification for chats).

the battery duration is regular.

the camera don't works some times.

is there a SD problem? (maybe only my phone or my sd broke)

clean flash: now.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Stricted:
yes all of that works
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] negatyw001:

[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] LuciferIII:
It's LineageOS, why do you need screenshots :rolleyes:
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Juuppi:
That is exactly what I experienced. Optimizing with EdXposed temporarily helped on the lagginess when I did a dirty flash. I didn't use it on that build for anything but that because I have no need for modules and it would probably have caused additional bugs.

LineageOS 16.0, ROM for the Samsung Galaxy S5 Neo vs aosp 9 treble?

Sorry for my English.

[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Stricted:
your best starting point would be to learn how to build

there are enough informations out there how to do it

dont take it personal but i dont like getting flooded with questions about how to compile android or how to port android to device x

i dont even understand what you are asking
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] SimurgAnka:
Hi i think he mean that questions;

1- is our device supporting treble(i can answer that: No)

2-which one is better treble roms or build roms(with device sources)

3-can we port treble in our device .I saw s6 edge treble port in xda enesuzun2002 was supporting that .Can we do that for our device. I suppose he edited their vendor partition and kernel(that was my question :D and i have a5 2016 variant )

Lastly i want to say thanks for everything danny and you , you are maintaining new sources and they are pretty stable i hope you will keep up good work.

Can I update on the original version 7, or do I need wipe?

Was it not to lose the settings?

Wipe complete or with cache is enough?
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Juuppi:
This new version is great! No lag problems anymore. I'm quite certain that sometimes it lies about battery percentage but I can live with that. Also, google clock isn't fully working sometimes. Sometimes it doesn't have any buttons for silencing it. I'm not sure if the problem is in the application or this rom, probably the app. It sucks when I have to reboot the whole phone to silence it.

[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Juuppi:
I just dirty flashed over 20190707 version of it. I didn't wipe anything. When I originally moved to this rom I had pixelexperience so I just did a clean flash.

---------- Post added at 04:58 PM ---------- Previous post was at 04:54 PM ----------

What do you mean with "original version 7"?
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] ernesto6556:
The native of the phone, the one she brings from the factory
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Juuppi:
So you mean stock rom. I have always just wiped everything when moving from one rom to another but I'm pretty sure it's possible to flash it after wiping system. So you don't lose your apps or other data. I'm not 100% sure but I may have even done that when I moved to this from pixelexperience.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] ernesto6556:
Hi [MENTION=9775440]Juuppi[/MENTION]

What version of twrp did you use to flash the custom rom?

Is it necessary for Los16 in s5 neo twrp?

Thanks
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Juuppi:
3.3.0-0 is the version of my twrp. I don't think it matters which version you use. As long as you use some recovery to flash it, it'll probably do the job.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] danwood76:
If coming from stock you will need to wipe, data, system, cache. If you are encrypted you will also need to format internal storage.

You can bring your settings and apps with you using Google backup. Backup all of your files in internal storage if you are formatting that.

Flashing over stock will result in huge problems.

Hi!

I have an unused S5neo.

I have installed TWRP 3.3.1-0 and wiped

- Dalvik / ART Cache

- Cache

- Data

- Internal Storage

- System

After that, I have flashed lineage-16.0.20190811-UNOFFICIAL-s5neolte.zip

After flashing, I rebooted, but the Phone stands (forever - or until battery is empty, depends on what is earlier ;) ) in the Boot-Screen (Samsung Galaxy S5neo).

What can I do? I have tried this several times.
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Stricted:
which model you have?

can you try to boot it and force reboot it to recovery and pull /proc/last_kmsg please?

you can force reboot it with <power> + <home> + <vol down> and right after that (when the screen goes dark) <power> + <home> + <vol up> to get into recovery
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] IngolfN:
I don't know exactly, which model. And because system is no more starting, I can't check. (it is a german phone originally from Vodafone).

Content of last_kmsg:

"Updating partition details...

...done

Full SELinux support is present.

MTP enabled"
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Stricted:
you can open the phone, remove the battery and look at the sticker, it will tell you the model

that is /not/ the contents of /proc/last_kmsg
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] IngolfN:
Model: SM-G903F

How I can view the content of this file in TWRP?
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Stricted:
you can either use adb "adb shell cat /proc/last_kmsg", you can use the terminal in twrp (under "Advanced") "cat /proc/last_kmsg" or you can navigate with the file manager (under "Advanced") to that file and copy it to somewhere where you can access it
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Stricted:
that is not enough, i need the whole file
[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] Stricted:
after looking closer at that log i see you are on booloader "G903FXXU1AOI7" which is Lollipop

you need to be on a marshmallow bootloader otherwise the device wont boot
