Thank you. Nice to see another Greek not only active but also good at developing. Good job!
[G4 Android Development] belrik:
Just a note to say that I have taken several working 2160p 42Mbit videos using Open Camera with the Camera2 API support enabled. Seems to be a workable route.
[G4 Android Development] kessaras:
Where is the 2160p ?

Me and even the developer haven't seen this number ?

I just installed open camera out of curiosity.

I thought wtf 1080 is the max ?
[G4 Android Development] belrik:
Enable Camera2 API! Bottom of the settings section in open camera

I can't screenshot the actual settings cos open camera is grabbing my volume keys but it's there.
[G4 Android Development] kessaras:
It's enabled already.

Maybe because I use hal3 for faster fps videos I don't have those resolutions.
[G4 Android Development] belrik:
Enable camera 2 API
[G4 Android Development] belrik:
Try restarting the app? It's been there for me since I installed the ROM, using default settings. No video issues here and I've been using Google Daydream VR too.

Note that you have to close the app before the changes are made, you might try force-stopping it.
[G4 Android Development] wartomato:
This is kind of ridiculous as it works for me with the stock snap camera... Seems more a RR bug... ;)
[G4 Android Development] kessaras:
Ok so then you all already can record a video on HD?

EDIT: [MENTION=6916498]wartomato[/MENTION] , i test stock kernel and llama to check it and yea you are right its RR bug that api2 is missing from open camera. Anyway footej has api2 enabled by default.

But i would love to check other resolutions too....... :(

When someone can, tell me if you already could record a video on higher reslutions than 1080p
[G4 Android Development] gazouille:
Hello,

This is my setting for footej, Google photo and open camera and 4k recording working good with this 3 app
[G4 Android Development] wartomato:
Yes...;) 4k, no Problem...
[G4 Android Development] kessaras:
Ok my temporary fix for the camera is still useful for those on RR and maybe other roms , but I really have to understand what's going on here.

I've been on RR for a long time.

How can lineage has api2 and a working 4k camera recording and RR which is lineage based has that bug?

Strange ?
[G4 Android Development] belrik:
I guess this is why the disclaimer usually says something like no other kernels, ROMs, xposed etc etc. They can be based on official Los builds but there are always differences, whether it's to accommodate additional features or because they don't pull in the newest los code as often. You're free to use whatever ROM you want of course, no criticism intended there. :) Nice that Los is getting new patches tho.
[G4 Android Development] kessaras:
Morning, i'm testing something with the official and it's working.

partitions:

/system F2FS

/data EXT4.

Gapps aroma installer didn't detect the f2fs partition , so i flashed only lineage and magisk and boot.

I download from apkmirror the magisk manager and flashfire , i adb push gapps into the sdcard and i use flashfire to flash gapps.

Working ;)

I have a f2fs system partition and i can say that its fast ;)

i kept data to ext4 cause data has a lot of read/write and i want it to have a faster i/o.

indeed video recording is working in the official. Wtf , how long do they have to sync with the official -_-
[G4 Android Development] z0mghii:
You want F2FS on /data not /system. Writes are the bottleneck in ext4 vs f2fs
[G4 Android Development] kessaras:
What is bottleneck ?

What do you mean ? I/O is faster on ext4. /data partitions reads and writes every second something new.
[G4 Android Development] z0mghii:
No I/O is faster on F2fs. F2FS outperforms ext4 in nearly all aspects. However since /system is read only and reads are extremely fast on both file systems, it was unnecessary to convert it to f2fs.
[G4 Android Development] belrik:
Depends on workload but usually the /system image isn't loaded in/out of ram as much as /data. F2FS was developed, originally by Samsung, to be a faster filesystem for flash memory.

History: https://www.xda-developers.com/f2fs-put-to-the-test-against-ext4/
[G4 Android Development] kessaras:
No... It's the opposite. I/O is faster on ext4 it's proved on op3t many times over and over.

OnePlus has default stock /data partition on f2fs.

After we format it to ext4 the boot time and the recovery mode boot time are reduced by 5 seconds or more.

How can that happen if I/O is faster on f2fs?

System is read only for the user operations not for the system itself.

F2fs is pre-caching everything. That's how it's faster later after some use. So I believe I'm fine as I am now.

Anyway the difference is small here. I don't really see any difference in speed like in op3t
[G4 Android Development] z0mghii:
That's simply not true. https://xdaforums.com/showthread.php clearly shows f2fs i/o being faster than ext4.
[G4 Android Development] kessaras:
showthread.php isn't a visitable link. you mean this one ? https://xdaforums.com/showthread.php?t=2697069

https://www.phoronix.com/scan.php?page=news_item&px=Linux-4.7-FS-5-Way

anyway i've seen those stats in xda from that member and its all crap.

i dare you do some tests on your own to check it with your eyes.

i told you in op3t we gain 5 seconds boot time. Can that be fake and that noob tests in xda be correct ?

his thread should be reported for stupidity but anyway -_-

EDIT:

1,71 MB/s random write speed on ext4 and 297,97 MB/s random write speed on f2fs ? LMAO.

i wish this xda comparison be closed and doomed to death xD
[G4 Android Development] z0mghii:
Thanks for correcting my link. Yes that is the benchmarks that I am talking about.

Even the link you sent me shows that F2FS performs considerably better than ext4.

http://www.phoronix.com/scan.php?page=article&item=linux-44-47-fs&num=3

http://www.phoronix.com/scan.php?page=article&item=linux-44-47-fs&num=4

http://www.phoronix.com/scan.php?page=article&item=linux-44-47-fs&num=5

Of course some benchmarks will show ext4 better, but it all depends on the use case. F2FS will not perform good on benchmarks designed to be run on desktops... The specific link that you showed included many benchmarks that do not closely relate to what a mobile phone does. PostgreSql on a mobile phone? Yeah right...
[G4 Android Development] kessaras:
lol. please check it again, i can't make this subject any bigger.

i/o performance is better on ext4, thats what we were talking about.

So i kept /data on ext4 and only changed the system to get a slight better performance.

f2fs is faster but not on i/o. Data reads and writes something new every second.
[G4 Android Development] z0mghii:
The i/o you are seeing is for database benchmarks unless you're running postgresql on your phone f2fs will be better on data for reads and writes. I'm not going to go try to explain any further, please do some more research. The i/o you are thinking of is not the same as reads and writes
[G4 Android Development] kessaras:
Ok anyway me I boot 5 seconds faster on op3t on ext4 , inside rom I don't see any noticeable difference in speed and

on my g4 even though I'm testing f2fs on system partition , I feel nothing.

Also f2fs on data partition on g4 did nothing.

On this phone f2fs or ext4 makes no difference. So... I'm just keeping it as it is now until I format again to flash a stock based rom that needs ext4 system.

Ending this from my side , I will just say that I don't agree.

Even though we both believe f2fs is generally better , I will never agree with the I/O performance unless I see it happening. As long as I see my phone boot 5 seconds faster to recovery , I will keep believing it :p
[G4 Android Development] Flaquito69:
What's new on build 2017-0516?? VoLTE is working?

:confused:
[G4 Android Development] wg2000:
If you are on 2017-05-02 or previous, massive improvement on the smoothness of animations and general feel of the phone. Otherwise, haven't noticed anything.
[G4 Android Development] Flaquito69:
Got it.

From my experience with the build 2017-0502, runs really smooth. So, I will update.
[G4 Android Development] wg2000:
Well, mine had noticable frame drops so maybe it will be just as fast for you...
[G4 Android Development] Flaquito69:
Runs very fluid!!! Compared with the 2017-0502 build.
[G4 Android Development] wg2000:
Yes, compared to 0502, it feels like a new device!!

A million thanks to the devs!
[G4 Android Development] hirsch3000:
I'm having problems with mobile data and calls on my H815. When I turn off the screen, wait some minutes and then turn on the screen again, the signal bar is crossed-out and I can't make calls or surf the web. Also, I cannot receive calls then. I tried multiple modems by flashing them using TWRP. Currently I'm using the 20G modem.

Did anybody else habe the same problem and was able to fix it? I really don't know what to try next and I don't want to return to stock.
[G4 Android Development] kessaras:
not happening here. But we are not on the same baseband version either. Me i'm on the latest firmware available. I flashed the latest 20p (H815).

1st try update your firmware. download from androidgx or from imperium kernel threads, the firmware update only and flash it. ( no need to flash a whole kdz and redo everything from zero ).

Then if flashing a newer firmware doesn't work, yes , go to that kdz method to update your phone.
[G4 Android Development] popy2006:
Hey guys, running imperium since a while but considering coming back to AOSP based rom.

Just some questions :

* does video recording works with built in camera? If not, what's the app u are using/recommended?

* is there excessive heat generated during video recording? That was one reason why I was gone back to stock based.

* ui slow down after some days of use. This was also a issue I was facing with aosp based roms. Is this fixed?

Thx pOpY

[G4 Android Development] kessaras:
Video recording works only on the Official Lineage. If you flash RR or some other rom and see that video recording isn't working, because for some reason the maintainer of the rom hasn't merged the fixes from the official, use my temporary camera fix. Search it in General.

How much heat ? The LG based doesn't heat up ? i'm changing roms frequently and the temp is always high while recording. That's normal. Video recording uses all 6 cores otherwise the focus would be slow.

UI isn't slow. It was never slow....... Can more people check it and correct me if i'm wrong ? Maybe you flashed a theme or font or something that used the gpu often
[G4 Android Development] popy2006:
1. Thx, will look at your patch

2. I had that feeling that heat generation during video recording was worse on aosp than on stock. But my experience was a months ago on RR

3. You are right, ui was never slow after reboot , it's faster than on MM stock based, but, if you run the rom a few days without reboot, it was getting slow. I'll think I was not alone with this issue. I and others posted this a several months ago. Again this experience I'll made a month ago. Maybe this has changed?

Thx pOpY

Another question : some months ago the was an issue which prevents you from unlocking when you have set pattern lock or similar. Lockscreen just froze after you come out from Standby. A workaround was to disable security at all. Is this fixed?

Thx pOpY

[G4 Android Development] kessaras:
Sorry , this one has to be answered from someone with a h811.

it was not a h815 bug.
[G4 Android Development] popy2006:
No, I have h815 EUR and had that issue some time ago.

Ok, maybe I should ask :

Anyone on h815 EUR using lockscreen security (pattern, ..) without issue?

Thx

[G4 Android Development] gazouille:
Hello,

No problem here with H815. Lockscreen pattern and record work great since a long time now. At least for me.
[G4 Android Development] popy2006:
thx a lot
[G4 Android Development] vmartinez39:
So wait, does this mean video recording is fixed on lineage camera app and also with the Google camera?

Status on the post says Beta, is this still the case?
[G4 Android Development] popy2006:
Another question:

Anyone using the ROM with android auto connected to an volkswagen, android auto compatible head unit?

If i am using RR (lineage based) rom, playing music with android auto (spotify) and do something which loads the cpu

(start navigation, maps is calculating a new route, voice recognition with ok google, ...) music starts stuttering a lot.

With imperium the issue does'nt come up.

Anyone else using android auto with this rom?

thx

Hello. Can I dirty flash los14.1 over my current los13?
[G4 Android Development] kessaras:
No.

Different api.

Gapps will have bugs. Otherwise if it was only about the rom , yes.
[G4 Android Development] polfrank:
Aren't gapps installed in the system? Format system, install los14, new gapps.... and profit!

Not gonna work, right? :P
[G4 Android Development] belrik:
You will need the original "experimental" Los 14.1 build for the upgrade to work, then upgrade to the latest weekly after that. Format /system to be safe. If h815 didn't have an experimental build then you need to wipe and reinstall.
[G4 Android Development] eriuzz:
this rom support vulkan ?
[G4 Android Development] kessaras:
Nope. But you can try before you wipe everything.

Use a third party app to backup apps data and restore this data after the update.
[G4 Android Development] ItzShadowz:
Sorry for bumping this after ages, but back when I was on Marshmallow (in the days phh's superuser to bypass Android Pay), I could use NFC perfectly fine (but it wouldn't let me use it as soon as I held my phone up to pay with it). Not being able to use NFC is likely not to be because of an unlocked bootloader. My friend is on stock Nougat (Nexus 5x or something) with an unlocked bootloader and his NFC works perfectly fine. Surely SafetyNet wouldn't have such an effect. RR is based on LOS now and it also has the same issue.
[G4 Android Development] Loffo:
Video does work

First post should inform that video does work except for QHD.

[G4 Android Development] wartomato:

[G4 Android Development] kessaras:
you need an update. genesix fixed it in his kernel , so now this rom can record 4k too.
[G4 Android Development] Loffo:
Thank you

Is it this kernel?

https://xdaforums.com/g4/development/kernel-llama-sweet-kernel-t3286514
[G4 Android Development] kessaras:
yup , his latest. Don't flash a wrong build.

And i think tyler must have merged it in his builds too. I haven't updated yet to know for sure.

EDIT: sorry we r in official thread. wrong thread to mention tyler.

anyway. official stock now has fixed it.

Genesix has fixed it too in case you use his kernel.

[G4 Android Development] pepo930:
I flashed the latest nightly along with gapps and everything seems to work.

On stock V20D I'd get ~48000 on Antutu, now I get ~60000.

After setting resolution to 1080p and DPI to 400 I get ~61000
[G4 Android Development] vmartinez39:
I noticed that when testing the latest lineage OS nightly, it still crashes when doing a conference call or 3 way calling. It crashes the UI when trying to manage the conference call. Is this still an issue?

Also the camera app had a record button next to the picture button, is this normal or new?

Hi, when in camera and click on the image preview at lower right corner the images do not turn to landscape, noor does the screen, are there a soulution to this?

Flashed a custom kernel

Installed or did mods from untrusted sources

Modified system files

Can I use F2FS with H815 official LineageOS?
[G4 Android Development] kessaras:
the new patching way can't.

7.1.2 is flashed unconditionally. it does not check for f2fs. So the /system will always be the same with the default partition format of the system.img.

EXT4 !

/data or /cache can be f2fs .

Same goes to any rom.
[G4 Android Development] JK-FINN:
I am going to buy a 128GB MicroSD card for this phone. Can I format it to exfat, does LineageOS and latest TWRP understand exfat?

And a second question: can I change the display resolution to 1080p, and how?
[G4 Android Development] PinBot01:
Yes, I have an 256GB exFat formatted SD-Csrd in my G4. Work very well[emoji1]

Gesendet von meinem LG-H815 mit Tapatalk
[G4 Android Development] JK-FINN:
What about the screen resolution: is it possible to change it to 1080p?
[G4 Android Development] thewild:
You can do it yourself, but it really isn't worth the effort.

I did it some months ago and switched back to native resolution, as I could witness no effect on performance or battery life.
[G4 Android Development] codeworkx:
The display will consume same amount of energy since you cant change the number of hardware pixels active.

But gpu will have less work and this should give better performance and better battery life. But only if you limit fps. If you don't limit fps it will produce as much frames per second as possible.
[G4 Android Development] thewild:
Yes, that's the theory. But in practice I never witnessed this gain in performance and battery life that I was looking for.

At that time I was playing Asphalt 8, and it was just as smooth in QHD than in FHD.

As for battery life, our screen is such a big power sucker that anything else is irrelevant, the gain in battery life was to little to be measurable.
[G4 Android Development] JK-FINN:
I just want my pixels, fonts and letters bigger on web sites, I have poor old eyes. That is the reason for 1080p, I don't game at all.

How to test 1080p?
[G4 Android Development] kessaras:
adb shell wm size 1080x1920

if you dont like

adb shell wm size reset
[G4 Android Development] thewild:
Then its not resolution but dpi you want to change.
[G4 Android Development] JK-FINN:
How to change DPI?
[G4 Android Development] wartomato:
In settings -> display
[G4 Android Development] kessaras:
same commands but use wm density.

first hit it without any number, wm density to check the current, then test a number, if you don't like anything, to reset use

wm density reset
[G4 Android Development] rigattoni:
Hmmmm...

With the last 2 Lineage versions the big kernels are switched off after some time and cannot be reactivated until reboot, even if there is high CPU load.

I switched back to 20170516 and it´s working again.
[G4 Android Development] kessaras:
if anytime you got trouble with a kernel or the cpu cores try my script #2 . it will only tweak the stock kernel settings, it won't add or tweak anything extra.

https://xdaforums.com/showpost.php?p=70966203&postcount=2

it will also help save some battery
[G4 Android Development] codeworkx:
How do you check that? I've seen that for example CPU-Z doesn't read properly.

It says some cores are offline but when u directly check sysfs cores are shown online.
[G4 Android Development] audinswfc:
Hi, sorry if this has been asked before but I searched the filename and nothing helpful came up.

I've just flashed this ROM after a long time away from custom ROMS. Seen the extras section and flashed addonsu-arm64-signed.zip (latest 14.1 version) but i'm unsure what this does? I've found the option to enable root in developer options, is that all it does? Wouldn't this option be there if the above hadn't been flashed?

Also, if I was to install SuperSU would that screw up my phone?

Thanks.
[G4 Android Development] tqwzUX6fn39GZMEzSnDF:
Yes, this file is for root only.

I don't know.

In general there is no need for SuperSu. But if you want to use it, you can remove "lineage" Su before: https://download.lineageos.org/extras
[G4 Android Development] audinswfc:
Cheers. Was expecting to see an app in the app drawer for it but that's fine :)
[G4 Android Development] rigattoni:
Hi codeworkx,

I use "Kernel Toolkit"...

The cores are shown online and working for a while and I think after deep sleep the cores are noted as offline.

I hope this is an issue in the Kernel toolkit app. :)
[G4 Android Development] kessaras:
Yeah that's all it does. ROMs are not rooted by default any more.

You can root with any method you like but first you have to unroot. Flash uninstall a root method before you flash another root method
[G4 Android Development] derBeukatt:
Makes sense.

Another thing I just noticed was, that I could create a new file on SD card via CM file manager but afterwards the three dot menu

will not open and i can only delete it via Total Commander. Strange things happening all over the place...out of ideas too.

Anyone been able to restore something using titanium backup? For me it can see the apps but claims that there is no apk and no data in the backup, probably the rom can not handle gzip correctly...

[G4 Android Development] neonoafs:
I was able to restore all my apps from the backup made on stock rom. If you did a nandroid backup, try to restore from that backup.
[G4 Android Development] FadeFx:
Did you store the titanium backup on internal or external storage? I have made a nandroid and am currently back to cm13. Gonna give the extract from nandroid a try later.

Gesendet von meinem LG-H815 mit Tapatalk
[G4 Android Development] InvalidCast:
on cyanogenmod migration page for g4 (but i think it's the same for other devices), it's written:

– Try to avoid restoring apps backup using Titanium Backup. It may break things up.

– Don’t restore system data using Titanium Backup! It will definitely break the current installation.

– It is also discouraged to Restoring Apps + Data using Titanium Backup.

i'm using cm since i owned a galaxy (the 1st), and i agree with that: i often ended in weird situations, restoring titanium backup, WHEN MIGRATING (otherwise it's a great tool)

i came to this conclusion: it takes me less time, once migrating, to configure all, AND THEN ONLY, make a titanium backup.

it's your choice, but i remember a lot of boot loops and force closes :)
[G4 Android Development] FadeFx:
I am perfectly aware of the dangers doing so, however, i wanted to try if it works and it just didnt, not because it lead to some issues, but because tb just could not handle the backups. Back on cm13 they work as intended, so its not a tb problem, as the tb changelog states that it was made 7.0 compatible.

Gesendet von meinem LG-H815 mit Tapatalk
[G4 Android Development] xrad:
At least in the past, CM officially endorsed "dirty flashing" across major versions, as in fact that's an update. You need to update gapps in the same go of course, but it should work. Doesn't that work for CM13->14?
[G4 Android Development] InvalidCast:
"Back on cm13 they work as intended"

--> you mean from 13 to 13, or from 12 to 13?

"tb changelog states that it was made 7.0 compatible"

--> to me, it means that it supports 7 to 7, not necessarly 6 to 7

but again, your choice. i hope you good luck.
