[ZTE Z7, Z7 Max, Z7 Mini] jruku:
Hello everyone, here is what troubles me these days :

On my Nubia Z7 mini (v1.20) I have problems to flash new ROMs ("NubiaZ7Mini_1.42_V2.8-Cuoco92", OR "blob5" OR "R3-1.82_TWRP_2.8.1.0_NX507J_Cuoco92&BB72"). I get everytime the message of e-verification failed....

My phone is rooted (Kingoroot) but I can't update binary SU using Super SU ou KingoSuperuser, it just doesn't work !

My recovery is TWRP 2.8.1.

What can be done to have a non-prehistoric version of software.

Thank you for your help.

I have Lg F240-EUR version, which is running on 4.1.2.but the software/os that came with the phone is slightly different from the original firmware.And the signal is sometimes dropping like showing x mark for 3-5 times a day.and the main problem is it cant be updated to any version.I checked in the IMEI website and found that my model is f240s.If I upgrade thehpone,i will loose signal forever as some people mentioned that they lost signal after upgrading their phone through custom roms or official firmware in other forums.I want to upgrade my phone to either official 5.0 or any custom 5.0 rom. please help me in upgrading my phone so that i shouldn't loose the signal even after the update.:confused:
[LG Optimus G Pro] lallolu:
I bought a similar refurbished phone from Aliexpress and the system information is the same as yours. I think they just messed with the build.prop so the build information looks ready for Europe. I will advise you to install the kdz so you have the Stock ROM and firmware. That was what I did anyway. The only porblem is that you will get some Korean apps but the phone is stable anyway. And when flashing, use "CSC" not "Normal" flash.

By the way, my phone was lagging very much before I installed the Stock ROM.
[LG Optimus G Pro] krishna13:
So after upgrading ,is ur phn showing signal normal?many mentioned that after upgrading they lost their mobile signal and their imri number to all zeros.so are u sure this wont happen to me?i am frm india.so there will be no problem with the bandwidths for networks in india?

At present even my phone running on 4.1.2,whenever i enable my data,after disabling it my signal shows x mark for 2-4 seconds then i will get back again.also some cals cant connect to my phn.so after upgrading,are there any chances of loosing my phone signal?
[LG Optimus G Pro] lallolu:
I cannot reaqlly gurantee your phone being messed up but mine works perfectly after installing the kdz. I installed the 4.4.2 version although there is lollipop version as well. I just want to try the kitkat version for some time.
[LG Optimus G Pro] krishna13:
I am unable to install custom recovery on my f240s.can u pls help me with the steps and links inorder to take backup of my current version. Also one doubt.If anything goes wrong after upgrading to lollipop (like if i lost signal in my phone) then after restoring the backup rom,can i get the signal back?? Also which is better? Some complained that after upgrading to lollipop they got signal issues.is installing kitkat= installing lollipop or is there any difference considering to the signal prblm?

(sorry for my bad english but i need help.pls suggest me)

[Java for Android App Development] MattMatt0240:
As stated above, I would go with codecademy.com since they just released a Java section. It has an interactive code editor during the tutorials. I learned all my html, css, and Javascript from that website, I highly recommend it.

Mybringback/thenewboston series on YouTube is also great for starting out.

[G4 General] GibMcFragger:
I have noticed the same thing myself. The G3 did the same thing. Even in bright light at ISO50, minor details are lost due to noise reduction. The advantage to the G3 was that you could use XCam LG to turn off the noise reduction. I wish he would develop it to work with the G4 also.
[G4 General] Ramsey:
I remember XCam from the G2 also, but I think the one for G3 is better with more options. If I recall correctly, the dev said that he doesn't have a G4 so he won't develop for it. Not sure though. I hope he does it too.

I had a Panasonic GX7 (Micro Four Thirds) and that camera had like 10 different settings for noise reduction, it was great lol. Wish phones get that level of control soon!

I like that HTC gives the option to change sharpness. That's also important.
[G4 General] GibMcFragger:
Are you rooted? Do me a favor to see if I am imagining things or not.

I changed ro.lge.noise.suppression to "0" (off) in my build prop, then rebooted. I took a few pics, and I swear there is no more detail loss when zoomed in.

I just want someone else to do it and see if I'm crazy.
[G4 General] Ramsey:
I rooted yesterday :). I'll try it out soon! I hope it works!
[G4 General] GibMcFragger:
Never mind. I took a few more. I think I'm crazy. Damn, lol. I was hoping I found it.
[G4 General] Ramsey:
Ok I tried it, no changes even after reboot =(.

That noise suppression could be for calls or mic :P.
[G4 General] GibMcFragger:
I just verified that. I'm an idiot. It IS the noise suppression for calls. If you go into your call options in the dialer, the noise suppression option will now be missing...

Lol oops. Just change it back to 1, then reboot and it's back.
[G4 General] Ramsey:
No prob lol.

This was a line added to build-prop to disable some noise reduction on the M9. I don't know if it will work with the G4 but it's worth trying. I don't have time now, maybe later I'll try it:

persist.camera.qcwnr.enabled=0
[G4 General] One Twelve:
I wonder if its a question of where focus got set. With the ISO 500 focus was spot on but with the ISO 50 maybe focus got set on the sheet further away.The patterns on the sheet on the ISO 50 look more clear compared to the ISO 500.

I can't explain the ISO 300 one though. The fur seems soft like the ISO 50.

Try to get more distance between you and the subject, at least 2m so we can eliminate focus as a parameter.

Did not understand the underlined bit. You were in manual to choose ISO for those 3 shots weren't you ?

If it is, its a damn good job. Face detect shows as one.

Does face detect get triggered in manual ? because with one of the shots in the photo thread i notice face detect was zero in the long exposure portrait.
[G4 General] vegetaleb:
What is weird is that it's mostly occuring on human skin. As said before thanks God we have RAW to control the NR and the jpeg compression. What is crazy too is that the difference is night and day between jpeg and raw even when saving at 100% jpeg quality using Lightroom on PC based on a dng it will recompress too much the pixels resulting in some color degradation. Perhaps LG is using a different color preset than the known adobe rgb ones...
[G4 General] s3alon:
Sorry but when setting ISO then it must be at Manual mode right ?

1/8, 1/24, 1/30

Sometimes even a bit movement might make a small blur which look like a noise reduction.

Correct me if I'm wrong.

but might want to try it like put on the table and took a shot from a consistent range and also set the manual focus to the preferred object maybe. :)
[G4 General] One Twelve:
That was my first thought with the 1/8. But the ISO 300 is 1/24 or fast enough. Even at 1/8 you can get clear shots with the OIS.

manual focus would be another way to eliminate any auto focus issues.
[G4 General] Ramsey:
I am pretty sure focus is set correctly and there is no blur from me shaking. The OIS is pretty good on the G4. The problem lies in LG's post processing where in lower ISO it is using aggressive noise reduction.

Face detect isn't activated in manual mode. I may be wrong though.

The one of my daughter isn't shot in manual mode, it was auto. The focus point may not be fully on her face, perhaps her neck area, but I have other shots that I won't share where I did focus on faces and the skin is too smooth. Tried using ProShot and the faces don't have that fake smoothing, they look natural and normal.

The NR is too aggressive so that it makes it appear as if I focused wrong. Even if the focus is on the sheet with ISO 50, why aren't there any fine details on the sheet like with the ISO 500? That's the aggressive NR coming into play.
[G4 General] Ramsey:
Yes it is in manual mode as stated in the beginning of my post, but note that the pic of my daughter was in auto mode.

If you zoom in you can notice that there is no shaking, that's just the effect of aggressive noise reduction below ISO 450 :(.

Look at ISO 500, notice that the fur has more detail. You can see a lot more noise in that picture over the ISO 300 one. That's how LG decided to post process and I don't like that low ISO has aggressive NR.
[G4 General] Ramsey:
What I mean by that is that auto mode has a special night mode that activates in low light and I think it takes away our ability to see ISO when that happens. Shots take longer to be saved also, but the results are pretty good. Manual mode doesn't have that feature and ends up with a lot of ugly noise in low light. I was just stating that I wasn't comparing the difference between those 2 modes, in case someone wanted to say that that's the night mode from auto mode causing that behavior.
[G4 General] One Twelve:
Correct, there is no blur that i can see in the 1/8 shot. Looks quite sharp. A little too sharp with patterns on the bedsheet just in front of the furry animal for ISO 50. So its not about shaking. But i'm not sure if focus got set properly.

My point is more about dof when focused on subjects less than 2m away. The G4 has a tendency to mess this up at times, picking the background instead of the foreground ie your intended target. So if you camera to subject distance is little over 2m then focus is at infinity or if closer than 2m you use manual focus then you get around AF, if indeed AF is responsible.

Show me more shots where we can eliminate focus as a potential cause.

if face detect isn't triggered in manual then there will be no beauty face.

Focus is perfect in your daughters shot. Action shot, crisp, what a lovely photo it is :)

Show me more examples.

---------- Post added at 05:06 AM ---------- Previous post was at 04:53 AM ----------

Right, your 1/8 ISO 50 is not a night shot. Had to be taken in manual.

Am doubting focus only in your shots. I am not convinced as yet that there is aggressive NR in a manual shot at low ISO. You did not use manual focus here it was AF. I think AF worked for ISO 500 but maybe not for ISO 50. That i think is the reason the toy at ISO 500 looks more clear.

I cannot say about ISO 300 though.

If you still did not understand, then see this

link

.

In the above you can see its more clear towards the center than top or bottom. For ISO 500, imagine the toy is in the centre, AF got it right.

i think with the ISO 50, toy is in the centre but AF picked the top. so it looks like this.

This happens when subject to camera distance is less than 2m. You say NR, i say (maybe) focus :)
[G4 General] t68kv:
Shot in manual with jpg and dng and compare how aggressive the noise reduction is applied to processed jpg as compare to dng even at low iso.

Dng output shows too much noise even at low iso and with adequate light though i have no other phone for comparison. This might be the reason why lg apply too much NR? Its like saying g4 camera is bad.
[G4 General] neflictus:
Yeah, you're not crazy. This is a serious issue.

I was coming from a Galaxy S6 and I bought the LG G4. Went to the park, took some photos of my son. Got home, saw them on the PC, zoomed in.....

Oh my Josh. It was horrible. Lots and lots of noise. And yes, the skin was the problem.

Took the same shots with a Galaxy S6 and they were just fine. Lots of detail, noise not even remotely close.

Bright sunny day outside.
[G4 General] One Twelve:
Your photo indicates face detect 1.

So let me show you some counter examples from one of the members here. Both are presumably in auto so face detect triggers when it can detect otherwise it does not indicate it detected a face.

20150726_170009 by Alluisses Kock, on Flickr

Face detect 0 so in theory no beauty face.

20150726_170024 by Alluisses Kock, on Flickr

Face detect 2

See the little boy's face. Is there any beauty face there ? because i cannot tell the difference between the two. These are good examples as they are in the same lighting, similar pose with same subject, with and without face detect.

Another pair

20150726_164936 by Alluisses Kock, on Flickr

Face detect 0

20150726_164941 by Alluisses Kock, on Flickr

Face detect 1

Any difference ? can't see it.

Check also the photos in his two albums, many portraits in there. i don't recall noticing any extra processing. This is the H815 but it should not make a difference.

Thanks [MENTION=4285659]shurensly95[/MENTION] and do you have any opinion on this 'beauty face theory' ?
[G4 General] defcomg:
ahhh okay i see will see where to add the selected item name
[G4 General] undercover:
Sorry chaps, i haven't read the whole thread, but to me it looks like a bokeh due to F number. If anyone has ever played with F1.8/F1.4 you'd see similarities. Loss of detail in the fur looks more like lack of light than anything else. What you see in the picture is essentially a reflection of photons, fur is great at dissipating it hence looks like a lot less sharp than surrounding light stuff.
[G4 General] Ramsey:
No it's not. I won't go into details but we found out it was because of the way LG implemented ISO and noise reduction. There is more noise reduction the lower the ISO. After ISO 450 you have less noise reduction. Tested many times with my phone.
[G4 General] undercover:
Fair enough. I'll read through the thread later.
[G4 General] neobdium:
Can u do it for lollipop plsss. because i change the files whit yours and camera is not working :( here are the original lollipop v10e files: https://mega.nz/#!sUQB1IJT!wJTDLHwItozo8Cn7WKbN52w1kb_F4CqzzLQwfjA8x34

That's crazy weird I didn't change nothing that would cause it to crash as for the disappearing camera try reboot again.

Did you set the permission correctly

Will recheck those libs later maybe I screwd up somewhere was sorta sleepy when copying the tables maybe lg added something in mm as I just copied the Table from mm lib into lp . I can't explain the disappearing camera tho that's too weird

i used G4 stock lib noise reduction profile on the M9 you can see what it does to details vs the modified lib V2/V1 this the best way to see the diff

i deed that but there is no diference, :( (and the libs have the exact size like stock)

Hello !! So, i read every post but there is too much information for my english skills...

So, if i am in rooted LP v10g i have to install the apk in the first post or install new libs as defcomg give to us ? (or both ?)

I am lost :(

Thank you !

damn thing crashes everytime on my H818p on v10L...
[G4 General] stewie-droid:
Defcomg...I copied those lib mods into directory but i am using stock ap and also lg v10 apk that installs just like an app. I'm assuming v10 apk will use same /system/vendor/lib directory correct? I'm didn't install the ap you have posted for noinse reduction off. Is this working also in auto mode or manual only?

Are those values adjusted only for low light situation? Thank you in advance.
[G4 General] stewie-droid:
Defcomg....anyone to get this 100% pic quality and bit rate mod get it working on MM ?

I coped xml files and changed premissions and no change in pic size therefore quality, not sure what else to do?

[G4 General] defcomg:
[MENTION=2695717]stewie-droid[/MENTION] every camera app will use those libs it was a while back but I think I only changed the lower iso value tables .

Don't know about the second I would shoot in raw if picture quality was the main concern. I would just use freedcam and use the built in profile editor there you can set whatever bitrate you want

Then if you mess with libs you can get crazy results I've achieved 1080p 73fps @ 56Mbps / 4K 34fps @ 160Mbps on SD800 device there was some mod I posted a while back for 39fps 4K for G4.

MOD NR LIB 5.1LP V10e.zip - [Click for QR Code] (38.7 KB, 36 views)

Can i use thie NR reduction LP51 for v10 on my LP 5.1 LG G4 H811-10N (stock cam) It took it but not sure yet what results will be. HOping it won't mess up anything.
[G4 General] defcomg:
You can try the worst that can happen is camera will fc
[G4 General] stewie-droid:
defcomg thanks. I am using now your LP v10e libs and they are working. Lots less noise reduction which means more noise in pictures but more sharp, i think.

Trying to figure out if that's good or bad lol......i guess have more testing to do. I'm using stock app, not modified and 100% jpg mod for picture quality which btw is somewhat not working it's suppose to at 100%. Anyway i'll update in the other thread on that but that's for libs. I'm wondering which is better, more grain or well post processed but more blurry if cropped in. Difficult answer to answer. If you or someone can shed your opinion on it it would be greatly appreciated. :)
[G4 General] defcomg:
I prefer a little more grain than over processed blurred look if you keep iso low and have good light sometimes the grain gives it that old school film grain look.

And with grain you can always denoise later if need be with blurred image you can try add sharpness but you end up with cartoonish looking image.

But if you have a tripod and a static scene freedcam has a stack mode where you can disable noise reduction and do median stack to reduce noise also if you into astrophotos in the stack mode you can choose lighten stack mode to create startrail images
[G4 General] ezzony:
Is there any way to conbine the 100% Jpeg mod with this noise reduction mod. Haven't installed either yet, just getting to grips with the stock cam manual controls atm which is all new to me..and fun :)
[G4 General] ezzony:
So I applied the mod on top of the 100% jpeg mod and once the camera app opened I'm getting an error message that can't be dismissed : "Internal storage full..." . Internal storage is not full or even close. Had to restore twrp backup I did before applying the mod. Any idea to fix this?
[G4 General] kiritoxda:
can you remove the noise reduction for video recording as well? when i begin recording the picture goes dark everytime when in low lighting, the same happens when using 3rd party apps for streaming.
[G4 General] neflictus:
Funny, the pictures look amazing. Indeed, no processing noticed on the face. The problem is not always present. But that doesn't mean it doesn't exist.

Can somebody add me to the LG G4 whatsapp or telegram group ? If they are subscribed. Please. Thanks.
[G4 General] One Twelve:
Still waiting to see an example that shows it exists.

Another pair, this one is tricky, i don't know if it is NR or shake.

20150718_153126 by Alluisses Kock, on Flickr

Face detect 0, seems a little sharper

20150718_153121 by Alluisses Kock, on Flickr

Face detect 1, little more smooth

Don't know why :confused:
[G4 General] vegetaleb:
It's a jpeg compression problem. A camera mod with no compression should fix it...or just use RAW ;)
[G4 General] Ramsey:
Were you shooting in auto or manual and what were your settings? ISO, shutter speed, etc.

I don't get much noise when I shoot outside or even inside below ISO 400.

I'd like to see samples of the G4 and S6.

Some noise is great btw on our little sensors because it means that the image is not too processed and you'll see more details. When noise reduction is strong then you'll get smudged results like on the HTC One M9.
[G4 General] One Twelve:
And another

20150718_203736 by Alluisses Kock, on Flickr

face detect 0

20150718_203737 by Alluisses Kock, on Flickr

face detect 2

Difference ? not apparent.

Should add that all of Aluisses shots are ISO 50.
[G4 General] Ramsey:
Oh boy, now Flickr requires me to sign in to view the original size. I suppose they added that requirement recently. I don't have an account with Yahoo :/.
[G4 General] One Twelve:
Agree

problem with m9 was the over sharpening, the recommended setting was to use less sharpening which is user configurable.
[G4 General] Ramsey:
I know what you mean, thanks to the f1.8 we get shallow depth of field and with the ISO 50 it could be what happened, but again, my other samples prove that NR is heavy below ISO 450.

I took many other shots on my own and it's always the same, below ISO 450 noise reduction is heavy regardless of the distance (< or >2m).

However, I must still mention that the quality is still great for a little sensor on a phone. Occasionally I get ugly pictures that are like using stock camera on a Galaxy phone (extreme noise reduction, masking details) and that's due to LG's strange post processing. By strange I mean not consistent.

I do agree that the G4 does tend to mess up focus with close distance, which is why I really wish LG chose phase detection. Focus could be wrong in the ISO 50 pic, but even if it is, I am still far enough to not create an extreme shallow dof that will blur out the fur. I mean the fur should still be crisp at that distance because it is close to the bed sheet and I am not super close.
[G4 General] One Twelve:
NR for which shots. You have mentioned two types, face which i cannot find evidence of. Aluisses examples are ISO 50.

the shots of the toy are not clear as to whether its focus or not.

Post more samples. Not able to reach your conclusion on NR yet.
[G4 General] Ramsey:
NR for the 50/300/500 ISO pics

Do you have the G4? if yes then try manual mode ISO 50, take a picture of anything, then try ISO 500.

I'll see if I can take more shots later.
