Well damn, now that I updated to the latest OOS 3.1.4 I find out that this HAL doesn't work with the newest camera libraries... What can we do for now?
[OnePlus X Themes and Apps] lagmasterx:
great!
[OnePlus X Themes and Apps] Aamod Joshi:
Does it work for the unofficial Resurrection Remix N 5.8.0?
[OnePlus X Themes and Apps] Fap4k:
No it will not work on any nougat rom
[OnePlus X Themes and Apps] jackiscoming:
can i remove it without wiping entire system?
[OnePlus X Themes and Apps] Kéno40:
Yes, just flash you full rom zip & wipe cache.

Edit : and if at the reboot, the camera app crash, just erase Camera app data.
[OnePlus X Themes and Apps] jackiscoming:
What do you mean with flash rom? i must reflash my rom? or only reboot in recovery and wipe cache? thanks
[OnePlus X Themes and Apps] Kéno40:
Yes no trap here.

In "flash full rom zip", I meant "flash full rom zip" !
[OnePlus X Themes and Apps] Sazoji:
The custom hal switched app works, you just need to have a rom without the mid installed to backup and a system root, then just switch to custom camera mode, install the mid, and you can switch just by using the app and you don't even have to restart (although if your camera is open in the process it will break until you restore the old camera backup)
[OnePlus X Themes and Apps] Nursh:
Any alternative if for CM14.1? Since this custom HAL doesn't work

OOS 3.1.4 ...

Hello i just installed it on OOS 3.1.4 and... I can't take pictures anymore, on snapchat it is good but any camera app , whatsapp etc not..

The 4k video recording works fine , but just taking a picture is broken.. Do someone have a solution?

I can't reflash my rom , it sais me fail " 7 " when i flash my rom , do someone have a zip file to revert to the stock camera libs etc ? Or the best ; if someone have a solution for my pics? thank you
[OnePlus X Themes and Apps] Potus ThePlant:
It's not compatible with 3.1.4. Maybe you should've read a bit before flashing all willy nilly. Regarding your problem, the quickest/easiest solution would be titanium backup->clean flash->restore apps.
[OnePlus X Themes and Apps] charliebigpot:
People.. the most recent update to this mod is from April 2016. Why would you flash newer OOS or even nougat roms and expect it to work?
[OnePlus X Themes and Apps] Yassine1313:
Thank you , i reflashed my rom and now i have the CAMERA HAL SWITCH, but is there not a version for OOS 3.1.4 ?
[OnePlus X Themes and Apps] yatin_bodwal:

[OnePlus X Themes and Apps] Kéno40:
Don't click
[OnePlus X Themes and Apps] Fap4k:
Which ROM you are using m8?
[OnePlus X Themes and Apps] Potus ThePlant:
Could you add a disclaimer in the op/title saying that this doesn't work with the latest oos? Some people seem to be incapable of searching the thread to check compatibility and it's getting annoying. Thanks.
[OnePlus X Themes and Apps] YulCmr:
Can it be possible to add a 240fps slow motion mode ?

Thx
[OnePlus X Themes and Apps] aryaraj:
Oos camera app crashes with the hal
[OnePlus X Themes and Apps] Kéno40:
Of course ;)

Lol is there a lot of phone of 2015 who does that? And even the OP3T stops Ã 120fps.

And you certainly mean a 240fps capture. This can then be slow down easily...

This HAL is for old OOS 2 version or some custom roms. Just read OP, last version is from april.
[OnePlus X Themes and Apps] Potus ThePlant:
Maybe you could read before flashing. It would save you time and the thread would be cleaner.
[OnePlus X Themes and Apps] 9888:
Can capable of lineage 14.1 ?????
[OnePlus X Themes and Apps] chaZ27:
Yes. Yesterday I flashed that mod and works fine except few bugs.

Sometimes its crashing in random cases. Also 3rd mode doesn't work (idk what mode it is *sorry* - from the bottom -> top Photo Mode, Camera Mode and 3rd ??? ) .

Its crashing also on taking pictures while capturing video.

I also recommend LineageOS 7.1.x - works fine but still some minor bugs.

I used Sultans ROM for half a year and it was great and I hope he will make 14.1 ROM :)
[OnePlus X Themes and Apps] Ghfran:
is this mod working for lineage os ?
[OnePlus X Themes and Apps] TravaPL:
OOS 3.1.4 here.

Strangely video and slomo video work but taking a photo crashes the app.
[OnePlus X Themes and Apps] Aashay:
This mod is not made for oxygen os 3. It'll work only on OOS 2. To undo what you've done, flash oxygen 3.1.4 and you'll be good to go.
[OnePlus X Themes and Apps] TravaPL:
I know. Just pointing out that it still works for videos and slomo, only photos need fixing.
[OnePlus X Themes and Apps] LolHacker17:
did anyone flash this on 7.1.1 rom ? why after i flash this mod only snap dragon camera work .. Oxygen camera (when i take picture it will force close) n colour os to
[OnePlus X Themes and Apps] :
Does Oxygen camera work fine without the custom HAL on 7.1.1?
[OnePlus X Themes and Apps] Mithrandir_:
No, no, no, no and no. If you read the last X pages, you'll see that this mod is not 100% compatible with nougat. The Oxygen camera won't solve the issue.
[OnePlus X Themes and Apps] :
Wrong quote buddy :p
[OnePlus X Themes and Apps] Arman Mallik:
hw can i unistall it?
[OnePlus X Themes and Apps] :
Dirty flash your ROM on TWRP and it will get uninstalled.
[OnePlus X Themes and Apps] Arman Mallik:
nw hw will i do dat?
[OnePlus X Themes and Apps] :
Check for instructions in the ROM thread.
[OnePlus X Themes and Apps] rgl12:
I know i got only one post right now (this one :P), but I know something about rooting phones etc.

I just got one question, just to be sure.

I got OPX with 3.1.4, and I've installed faulty this MOD without reading last posts of this thread.

SO, just to be sure what I should do.

I got TWRP blu-spark 3.0.2, and supersu 2.79, so only thing i should do to make work again my camera is to install via twrp 3.1.4 rom from oneplus download site yes?
[OnePlus X Themes and Apps] Kéno40:
Yes. Reflash full rom zip, SuperSU and wipe caches. Reboot !
[OnePlus X Themes and Apps] rgl12:
In TWRP (select partitions to wipe) - dalvik, system, data, cache, internal storage and it should be perfectly clear yes?

I dont mind to customize everything from the begining - thats not a problem for me.
[OnePlus X Themes and Apps] :
If you want to dirty flash your ROM (to just make camera working without customizing everything from the beginning) just check Dalvik & Cache.

But, if you want to clean flash your ROM (it will be like having a brand new phone) check them all.
[OnePlus X Themes and Apps] rgl12:
Okey, now I know everything. Thank You.
[OnePlus X Themes and Apps] Mayeen:
Is it possible to somehow have EIS on the Oneplus X?. It's something to do with software unlike OIS. Is it possible for a developer to add this feature?
[OnePlus X Themes and Apps] MrMysakovichCZ:
Lineage 14.1 has this function under Snap Camera app. But it is only cut resolution with zoomed. So quality is nothing special..
[OnePlus X Themes and Apps] Mayeen:
But the shakes won't be there right??
[OnePlus X Themes and Apps] MrMysakovichCZ:
I think that it was stabilization for shaking. But I do not remember it correctly. I must highlight you before you install LineageOS 14.1. It is not stable for daily driver and has lot of bugs. So better is wait for stable releases (If it will be?)
[OnePlus X Themes and Apps] Mayeen:
Yes I'm talking about stabilization.. My bad..:)
[OnePlus X Themes and Apps] YulCmr:
I understand that the result won't be very clean if this option can be added, but the question was, is the hardware capable of recording at 240fps ? whatever if the result is clean or not. (And I guess it would need A LOT of light to be able to see something at 240fps) I would be curious to test it.
[OnePlus X Themes and Apps] Dinesh6252:
why front camere quality is reduced after installing this mod ? pictures taken from front camera are not that good after this mod..
[OnePlus X Themes and Apps] cpaleop:
I have flashed it on Lineage OS. On every version of the rom, when I'm trying to record (at any resolution) the video immediately stops recording and there is no output saved video stored. Before installation the video works fine.
[OnePlus X Themes and Apps] Aamod Joshi:
See this
[OnePlus X Themes and Apps] cpaleop:
Hey sir, I don't understand your problem. I know that I have a new rom, and I know it's nougat. I just experimented with the mod on the rom and i'm just 'reporting' a bug If you like.
[OnePlus X Themes and Apps] Aamod Joshi:
My point is, people have been 'reporting' this bug that it doesn't work on Nougat and OOS 3.1.4 on many threads. A person who comes here, if he doesn't scroll through the previous posts or search for the stability in the thread, then he would create a new thread 'reporting' bugs. If everyone does that, then it means that there will be unnecessary threads in the post and that too too many of them. To avoid that, it is recommended to search through the threads before creating a new one.

You can put [EOL] sign or ask the dev to do that, so people don't get confused

Camera problem

I flashed the above zip provided by you

But for some reason camera app stops whenever I take selfies

I have used all different camera apps

But I'm getting the same problem

Can u fix it!

Please

Other than this everything is working good

Thanks?
[OnePlus X Themes and Apps] Aamod Joshi:
Which ROM are you on right now? And which Android version is it?
[OnePlus X Themes and Apps] Dinesh6252:
Why the front camera don't take good selfies after installing the zip? Plz someone tell
[OnePlus X Themes and Apps] anil20259907:
Oxygen os 3.1.4

I'm currently on oxygen OS 3.1.4
[OnePlus X Themes and Apps] Kéno40:
So that's normal.

This HAL is one year old.

It was for OOS 2 Rom or CM13.
[OnePlus X Themes and Apps] Aamod Joshi:
The mod is for OOS 2.x and not OOS 3.x, so it'll happen. If you want to use this mod, try Sultan's CM 13.0, it works on that. Or you could revert back to OOS 2.x.
[OnePlus X Themes and Apps] aryanraj457:
can i flash it on h20 marshmallow or oxygen 3.1.4

can i flash it on h20 marshmallow or oxygen 3.1.4:):):)
[OnePlus X Themes and Apps] Sytis:
Did you even read the comment just above you? Yes you can flash it, but not everything will work.
[OnePlus X Themes and Apps] pradyum_p:
I'm currently on OOS 3.1.4.

I don't want to revert back to OSS 2.x.

For me the same problem is there. I'm not able to take selfies.

Is there any other procedure to remove this MOD.

Because nothing is working with the camera.

Only thing I can do is take videos. How to remove this MOD now???
[OnePlus X Themes and Apps] Kéno40:
Seriously, you are blaming devs because you flashed stuff without reading what was inside?

Just reflash the full rom zip from here.

[OnePlus X Themes and Apps] Kéno40:
Just read the post on the pages before
[OnePlus X Themes and Apps] Aamod Joshi:
Guys, please don't ask if the mod will work on this ROM or that ROM. Just apply your common sense, the thread was last updated even before the Nougat was there for our device. So it's obvious that the mod won't work on any Nougat ROMs.
[OnePlus X Themes and Apps] alabama20:
This thread should be closed by now IMHO
[OnePlus X Themes and Apps] Aamod Joshi:
Doesn't matter, people shouldn't ask the same questions over and over again.
[OnePlus X Themes and Apps] alabama20:
That would be an ideal world ?
[OnePlus X Themes and Apps] Kéno40:
Yeah, but read at least the first post and the 2 last pages before reporting should be mandatory.

On the other side, Sultan could have add a note on the first post...

Installation Failed

Ive got a OnePlus X having OxygenOS Version 3.1.4, Android Version 6.0.1 and everytime i try to install this it shows installation failed.

Ive followed the procedures exactly but im still unable to do anything with it.

Any suggestions would really help
[OnePlus X Themes and Apps] Sytis:
Maybe reading the OP is good start, this mod is ! only! for Oxygen 2.X and not 3.X so you won't get it to work most likely.
[OnePlus X Themes and Apps] Aamod Joshi:
Which recovery you got?
[OnePlus X Themes and Apps] saranglfc93:
Im sorry but i dont understand what do you mean by what recovery have i got.

Is there any way i could know?
[OnePlus X Themes and Apps] Kéno40:
reboot to recovery and tell us which version it is.

Last official is 3.1.1-1
[OnePlus X Themes and Apps] 9888:

[OnePlus X Themes and Apps] alabama20:
No, obviously...

what should i be doing next to get this Mod
[OnePlus X Themes and Apps] saranglfc93:
Would i lose all my data incase I want Oxygen 2.x?

I really want the option of recording in 4k and i cant buy a new phone so this seems the only option

Do you know how to unflash this or undo this??
[OnePlus X Themes and Apps] naa2773:
You need to dirty flash your ROM again.

Where does this mod come from? Did somebody port the Sultan's HAL? Did somebody test it on OOS 3.x?

Flashable zip to return to stock OOS 3.1.4 camera HAL

Hello, like many others I installed this camera HAL on OxygenOS 3.1.4. I later learnt that the mod is not supported on OOS 3.x and I could not take any photos.

I created a flashable zip to return to stock OOS 3.1.4 camera HAL which I used to fix the camera problem and share it on this post to help others . I created the zip by replacing the files in the modded HAL with files from the OnePlus X OxygenOS 3.1.4 rom.

The .zip is attached. Anyone who wants to return to stock OOS 3.1.4 HAL can flash this instead of the flashing the entire Oxygen OS rom. Note that I have only flashed this myself whilst running OOS 3.1.4. The zip may not work properly on other roms, but that is not the intention of the zip anyway, it is just an 'undo button'.

Cheers :)
[OnePlus X Themes and Apps] aa_vi:
thanx :laugh:
[OnePlus X Themes and Apps] TravaPL:
Works beautifully on Oreo. 4K recording is limited to 10 minutes though.

I tried to install it (LOS 14.1 Nov. 18 build) and it does not function. How do i have to install it? Every time i flash the provided latest zip for mod and it crashes the camera. Deleting data for camera also does not function. What am i doing wrong?
[OnePlus X Themes and Apps] Kéno40:
It's really an old stuff. That's all...
[OnePlus X Themes and Apps] mafri1:
OK, so there is no possibility to install it?
[OnePlus X Themes and Apps] Kéno40:

PS : just go to RR pie Version. It's really a marvellous ROM !
[OnePlus X Themes and Apps] Roadie#42:
YumeMichi has just released a LineageOS 16 build with Sultan's custom HAL. It works properly.

... You got me wondering: does RR have Sultan's HAL built-in?
[OnePlus X Themes and Apps] Kéno40:
As there is not 4K video shooting option, I'll say NO.
[OnePlus X Themes and Apps] Roadie#42:
There is.

Be aware to download the proper 20190314 build under sultan-camera from his basketbuild.

I use Open Camera for 4k DCI. Only UHD in built-in camera.
[OnePlus X Themes and Apps] Kéno40:
The question was : does RR has sultan's HAL? My answer : probably not.

Oh damn sorry I mixed everything up ?

Hello there !

I have an issue with the Sultan Camera on my Oneplus X (Custom Rom => Bootleggers 4.3 Stable).

I flashed the zip, then I rebooted and tried to launch the camera app. But its crashed ! Here is the crash log, maybe someone can find a way to fix it (@sultanxda ?)

[OnePlus X Themes and Apps] Tiongkia:
Thanks op. Great work. Appreciate it. Worked well on oss 2.20 with blu_sp r94.
[OnePlus X Themes and Apps] Rotpeter:
Thanks OP, appreciate the effort. Doesn't seem to work with my CM13 camera, though. In the app the new resolutions appear, but the output video cannot be played by VLC or internal gallery app. Just one frame and the sound appear. :(
[OnePlus X Themes and Apps] Sultanxda:
After further investigation, I found out that everything listed under the caveats list is lost forever, except maybe for manual ISO control. Manual ISO control would be hindered a lot though (it'd be pretty much useless in its current state), so I removed it entirely.

That being said, the HAL itself is pretty much the best I can make it as of the Feb. 16 build (there are lot of tweaks I made to it that aren't listed in the OP). There isn't much more I can do to make it better at this point, aside from bug fixes for random bugs that may pop up from time to time.
[OnePlus X Themes and Apps] pquinqu:
Hi, seems that mod have a kind of magic... that seems to work also with htc camera on 1+x. Never had before full hd and 4K video recording. Seems also that pictures taken in low light conditions have much less noise than before.

Many thanks.
[OnePlus X Themes and Apps] eldoro80:
Thanks!

Thanks for this fix! Now I'm happy about buying the opx... Wasn't that happy since buying it 2 months ago.. At last I can make videos again of my children growing up..
[OnePlus X Themes and Apps] Sultanxda:
I'd try the OPX for at least a few days if it didn't require a nano SIM. The OPO uses a micro SIM slot, so I'd have to cut my SIM card down, which would make it difficult to go back to the OPO if I didn't want to use the OPX (I don't want to stick tape into my SIM card slot again to make it fit :silly:).

[OnePlus X Themes and Apps] Hoej:
Thank you man, this works really well with respect to the caveats listed, of course!

Comparison of video footage before/after applying this mod. Video seems a bit darker, but there's a LOT more details and no noticeable more noise.
