feedback: xposed easily was installed on this rom ( needs a zip file to be flashed before install "xposed installer" apk ) and greenify can setup its xposed module to use it.

[MENTION=6504624]Exodusnick[/MENTION] thanks for your response and your greate work (i`m programmer and i know your hard work over this project-i appreciate that), i`ve got some statistics from "system panel" (probably you know: used to monitor cpu processes and so many other controls-in my opinion its the best application ever, in this region) states that there is remarkable amount of battery draining originates from ROM, not from programs you`ve installed (so you can`t prevent this issue using third-party applications such as greenify which i tried). actually "system pannel" shows a category named "unaccounted" which belongs to processes that their source cannot be recognized (i didn`t install many apks, to test these issues first - so absolutely this comes from ROM). but the other andorid`s processes usage are reasonable.

i`ve attachd "system panel" statistics i`ve got for an hour, for your consideration.

[MENTION=6504624]Exodusnick[/MENTION], guys this rom is absolutely stable with no issue, but could you reference

me a custom rom on android 6 or 7 for samsung galaxy s4 i9515 - jfvelte, which are better optimizied with battery ?

how about cm13 or cm14 by [MENTION=5010221]sombree[/MENTION] ?

many thanks.

[MENTION=9655399]am1r_5h[/MENTION]

[MENTION=5010221]sombree[/MENTION] has stopped his work currently because he has no time, which means I am the only one still supporting the samsung galaxy s4 i9515 - jfvelte is doing under 14.1.

And 15.1 what I'm working on we don't need to talk about for now, the project isn't going well at the moment.
[Galaxy S 4 General] am1r_5h:
[MENTION=6504624]Exodusnick[/MENTION] thanks for your response,

do you have any plan to improve battery life over this rom on next build if there will be any prospective build for 14.1 , this rom is perfect? or you`re just intended to work on 15.1 ?
[Galaxy S 4 General] Exodusnick:
I currently have no plan to improve battery life below 14.1

build 15.1 is not ready to be used in everyday life yet
[Galaxy S 4 General] am1r_5h:
thanks, good luck
[Galaxy S 4 General] Exodusnick:
[MENTION=9655399]am1r_5h[/MENTION]

to improve the battery life you can still use the app Kernel Adiutor (ROOT)

Battery life is mostly made up of the kernel, e.g. scheduler stories etc..

Did you fix problems coming out with wi-fi and bluetooth sometimes not properly working ?
[Galaxy S 4 General] Exodusnick:

I don't have Wi-Fi and Bluetooth problems
[Galaxy S 4 General] francyspi80:
[MENTION=6504624]Exodusnick[/MENTION]. I installed latest LineageOS 14.1 for Jfvelte and flashed the baseband I9515XXS1BQD2 with TWRP 3.2.3-0. I'm facing problems when I switch the phone off and then on again later. The wifi and bluetooth don't work and i am forced to restart it again to have them working.
[Galaxy S 4 General] Exodusnick:

https://xdaforums.com/galaxy-s4/general/ref-galaxy-s4-i9505-modems-bootloaders-t3315987 Like I said, I don't have any problems.
[Galaxy S 4 General] am1r_5h:
i`ll be checking that app, thanks for your response. but the one more thing i`ve noticed is that, its the bluetooth drainig battery fast while i have it paired with headset or smart watch; its usage is a little bit more than lollipop stock rom i`ve had. is there a way to optimize bluetooth battery usage via overwriting or flashing a framework or modifying something in the kernel ?
[Galaxy S 4 General] francyspi80:
Thanks. Are your partion formatted on ext4 to F2FS ?
[Galaxy S 4 General] am1r_5h:
this rom doesn`t have any issue with battery draining, actually it has some issue with reporting battery stats correctly.

Can you test if your WLAN problem is solved by this?

[Galaxy S 4 General] Exodusnick:
[MENTION=7582387]francyspi80[/MENTION]

i have tested it several times now and my wlan switches itself on immediately when switching off or restarting the device automatically, and also during the build update.

and I have the modem/bootloader I9515XXS1BQD2

it could also be the WPS!!!!

In the router used times look whether WPS is on. With me it is off ...

Thanks for interesting in my problem. Frankly is not a WPS issue. I'm going to flash the modem/bootloader I9515XXS1BQD2 by the link above and i will come back to you soon. ;)
[Galaxy S 4 General] am1r_5h:
[MENTION=6504624]Exodusnick[/MENTION] Does Wifi-direct work in this Rom ? I could connect to other devices via Wifi-direct but receiving file while they are connected is failed. I tested with two different devices and the file couldn't be received.

and also when I'm going to send a file while devices are connected, there is no Wifi-direct option in Share menu to be selected !!! but sending with Bluetooth works fine through Share menu. I will be appreciated if you respond.
[Galaxy S 4 General] Exodusnick:
Wifi-direct works......

I've been using SuperBeam for a long time (plus SuperBeam pro unlocker) and I have no problem sending files when I'm on the same network the app must be installed on both devices.

https://play.google.com/store/apps/details?id=com.majedev.superbeam&hl=de
[Galaxy S 4 General] am1r_5h:
I know what you mean, There are some 3rd party apps which ease transfering files via wifi, but as you surely know you can send files without 3rd party apps, using wifi-direct. I mean in stock rom, when you select a file in any file manager and then select Share, you could choose wifi-direct option from Share menu, and then its possible to share file without any 3rd party apps, but in this rom there is no such option as wifi-direct in Share menu to choose. why? Should I do someting to reveal this option in share menu? or the only way for using wifi-direct is installing 3rd party apps in this rom?
[Galaxy S 4 General] Exodusnick:
[MENTION=9655399]am1r_5h[/MENTION]

you miss the optzion then you have to go back to stock , under 14.1 there is no more that you have to install a 3rd party app that makes it work .....
[Galaxy S 4 General] Exodusnick:
got you it done?
[Galaxy S 4 General] francyspi80:
I flashed the modem/bootloader I9515XXS1BQD2 by TWRP 3.1.1.0 but i'm facing the same problems when I switch the phone off and then on again later. Wifi doesn't work and i am forced to restart it again to have it working.

It's really annoying. Any idea to get it serviceable? Am I the only one here?
[Galaxy S 4 General] guest4711:
Toggling airplane mode on and off may allow restarting wifi, too. (I used this method when I had this problem on another rom.)
[Galaxy S 4 General] Exodusnick:
Have an idea, try to turn off WPS in the router used.
[Galaxy S 4 General] francyspi80:
Thanks. I will try this workaround.

Exodusnick it cannot depend on WPS's router. Wi-fi is not set on sometimes so it's a problem depending on the phone.... Damn it!!! :rolleyes:

[MENTION=6504624]Exodusnick[/MENTION] ; I have two problems with this ROM:

first, when I receive a call while I`m listening to musics I have no voice of the person who is calling; I`ve read in some forums for disabling "OK google!" in google assistant, but I`ve installed pico version of gapps and there is no google assistant... but when the phone is not playing musics everything is fine.

second, I have my numbers in sim card and the sim contacts couldn`t be loaded !!! actually there is no option in "contact to display" which says "sim card" to display sim contacts, an also when I try to export phone numbers to "sim card" it says "unable to load sim contacts"... as you could guess, the sim contacts couldn`t be recognized while the sim card response fine, and I can make/receive calls ..

any workaround ?
[Galaxy S 4 General] Exodusnick:
That can't be, I just tested it and it works when music is playing and a call comes one both callers hear themselves.

[Galaxy S 4 General] am1r_5h:
despite [MENTION=6504624]Exodusnick[/MENTION] great work, experience of running the device under this ROM for a month eventually led to have the stock android 5.0.1 lollipop back, the Rom is stable but there are some issues:

- the Rom doesn't report battery stats correctly

- battery life is not awkward but streaming via Bluetooth drains battery remarkably (4% every 15 mins), wifi and mobile data are roughly reasonable. if you are interested in android 7 on your phone, you can benefit from "app ops" and "servicely" for some tweaks to promote battery life somewhat. (if you keep the device standby, battery draining with some tweaks is roughly 1% an hour, but if you use the device (mobile data - BLUETOOTH streaming ), 25-30% an hour)

- when your battery is under 15% with bluetooth on, turning on mobile data or any action need to be processed for example camera, caused phone to be turned of suddenly (all these actions in low battery with stock rom are recognized, and you cannot take those action while your device battery is low, i think this is better than your phone be turned off suddenly)

- while streaming music via Bluetooth, AUX, ... if you receive a phone call, usually you lose voice call, and nothing is heard - restart is needed.

- sometimes wifi cannot be turned on , and you should restart your phone first.

- restarting device (long press power button and choose restarting) sometimes does not work, actually screen will be black and you think its restarting but not, Intuitive buttons work and make vibration when you press them but screen does not come back and you need to long press power button to turn device off and turn it on again.

- the stock android has a superb camera built-in app ever, if you really want those shooting modes back, you need two apps "a better camera" and "camera zoom fx"; however, comparable to built-in app, they cannot satisfy you.

- sim card contacts could not be loaded and device can not display sim contacts (i think this feature is not included in aosp-based roms and need to be programmed - just like stock roms) so you need to sync contacts to google, to restore them after you install aosp-based rom.

- in contrast to stock rom, there`s not built-in wifi direct support, and you need a 3rd party app to be installed on both devices such as "shareit"

- built-in launcher is awful, but can be replaced with great launcher "lightning launcher"

- built-in samsung keyboard is really great: if your mother`s tongue is English you will not have problem, but I tested 10-15 keyboard apps for my language and nothing takes samsung keyboard's place.

- and as a last point, if you feel comfortable and relaxed with stock rom, you will probably try to have those settings or features you had, back in this rom. so you need to spend a lot of time and eventually you will be back on stock rom.

if these are not vital issues for you, the rom is great...

in my opinion, you can use "samsung s4" for next 1 or 2 years maximum(depends on what you do with your phone and what you expect from your phone), and for these years stock rom is better choice than any custom rom.

I dont know how do you test which can't find any of those issues and find every thing fine !!! I'm not crazy to make up bugs, instead of threatening me to report to xda if you are not able to find those issues or fix what you've provided, the same as other you can get vanished and don't support any more. I'm wondering you will launch android 8, its absolutely worth flashing... maybe you should provide android 9 before google release it.

great work, thanks. just encryption is missing

Thanks a lot for the great work, so the S4VE is still alive. Now wifi works fine; before I had to start the phone sometimes several times, until wifi works.

Before I changed to your ROM, I had the one from sombree. He stopped (it seems he works on 15.1). With his ROM I could use encryption.

Unfortunatelly encryption with your ROM doesn't work. I tryed twice. Afer charching the battery to 100%, I selected encryption: endless loop, every few minutes the phone startet, I waited more the 12 h. Afer this the phone could not start at all. The way to get it back was by formating data (TWRP), and then restore the backup. VERY IMPORTANT: After formating do NOT restart the phone, first restore the backup and then restart. Otherwise your backup is gone (formatted).

My SD-Card ist used as internal storage.

Can you give my a hint, how to encrypt the phone? Thanks.
[Galaxy S 4 General] Exodusnick:
hi [MENTION=8616828]klaus_la[/MENTION] for what do you want to lock your phone, password and sim pin is enough but in my opinion enough from .I have never encrypted my phone,

what is doing is to encrypt your backup , but not your phone .

read the times through or google times yourself, it has not really advantages an encryption .

Enable Android encryption? - Advantages & Disadvantages explained

Is Android encryption any good at all? We explain the advantages and disadvantages and how you can activate it (also for your SD card).

Starting with Android 6.0, encryption is automatically activated on selected devices with sufficient performance - such as the Samsung Galaxy S8* - (but you can also encrypt the SD card there). On other smartphones you have the choice if you want to set up the encryption afterwards. However, this has advantages and disadvantages.

Advantages & Disadvantages of Android Encryption

Allegedly, you should always encrypt your smartphone if data protection is really important to you. Otherwise strangers can read your data on the device and on the SD card, even if they don't know your PIN or display lock.

Advantages

possibly protection of your data from unauthorized persons

drawbacks

Operating system may run 50% slower

Encryption can be cracked

Encryption is often not so easy to undo

Conclusion

Android encryption encrypts accounts, settings, apps and your files. This means that third parties can no longer read your data, as only an encrypted data jungle is recognized - as far as the theory goes.

Let's come to the disadvantages: Depending on the smartphone, operating system version and knowledge level of the criminal, the Android encryption can also be completely hacked. In addition, according to tests on the Anandtech website, encryption on a Nexus 6 has slowed performance by 50 percent; this includes read and write access as well as games.

The Android encryption is not (yet) really worthwhile.

The disadvantages clearly outweigh the advantages, especially since the protection is not 100% secure.

Apple's iPhones encrypt much better.

If you still want to encrypt your device, you can do this as follows.

no it doesn't, sometimes it crashes and get restarted (in particular, when using camera - camera APIs doesn't work properly, taking panaroma using built-in camera usually crashes for instance. or i tested several 3rd party camera apps (camera zoom fx, a better camera), they crashes too when you are taking some picture or try some shooting modes).

in addition, when the battery is below 20% not every but usually some activities leads to restart while the battery is new.

Some have problems and others have no problems at all.

Hi,

I have tried the lineage-14.1-20190207-UNOFFICIAL-jfvelte.zip, and tried to make a call in my car with bluetooth connected. The problem was that they did not hear me, as if the microphone did not work at all.

I have found this, please take a look, maybe it helps to fix this issue:
