[Q]Black line problem when I using CM7 Mod

Hi XDA,
As you can see my Attached Thumbnails,when I use the camera apps(build-in CM7 Camera and other camera apps), there are some black line in the preview mode but the photo I taken didn't have these black line. This situation is only happen in CM7 ROM, the officual ROM doesn't have these problem. In the past I flashed CM7.1 into my gio phone, I got the same black line problem when I playing the video.
can somebody please help me to solve it?
THX
Sorry for my bad English

If you have this problem only in the camera, then these are the "guidelines" , which are to help you when taking a photo. You have to search for them and turn it off at the camera's settings.

I don't think this black lines are the "guidelines" because I reboot the phone,the black lines will disappeared. However,when I idle the phone a while and open the camera, the black lines are come back. Also I got the same black lines when I playing the videos(especially in CM7.1)
Now I back to use the official ROM.

Its a total diverend isue and has nothing to do with your camera.
It has something to do with your screen, not that the screen is defective but something with the drivers.
There is no fix for it, not that i am aware of.....

Are you install it right according the installation guide ?
Have you tried to reinstall ?
Anyway, which version of Gio do you use ? the GT-S5660 or SHW-M290S/K one ?
CM7 only support Gt-S5660 version

Try CM7.2 and see how is it. Remember to Wipe factory reset after installing Rom. If it repaired, try stock ROM like gingerbread and let us know how it is going

I done it long time ago but the problem continued in CM7.2
Stock ROM is fine

I had a similar problem with CM7.1, exept it wasn't black lines, but semi transparent squares. It happened, after I installed a camera app (don't remember, which one). Did you install any app that uses your camera? (My problem went away after installing 7.2)

I installed camera360 and little photo
Did you change the battery before using the camera??? I discovered that it may make the transparent squares happened.
Now the problem still happened after install the patches.

S4 mini reboots

Hi every one.
I have a brand new S4 mini and I am pissed of because it reboots it self few times a day,sometimes 1-2,one day I had almost 20 reboots.
There is a saying in my country: how much money,that much music, and i am pissed because this phone costs almost 1000 dollars in my country and for that money it should be composing brand new simphonies
I try various solutions and before going to the store I would like to fix it my self if possible...and one more thing I don't want to break warranty by fixing it my self.
I ruled out this issues- faulty SIM(got a new one,same thing happens)
- SD card problem(with or without it it's the same)
- app related issues(it's the same with or without updating apps,was it on 4.2.2 or 4.4.2)
I don't have another battery so I can't test this one.
I also noticed that sometimes if app crashes(frezees) I don't have the force close dialogue,instead the phone reboots so I am thinking that this could be the problem.Is there a way to turn on force close dialogue?
The thing that pisses me the most is that on HTC wildfire S I could get it to work for 500+ hours without rebooting it my self,and on this one my record is 17 hours without reboot.
Thanks to everyone who will try to help me.

If you don't want to break your warranty, then go to service center with your phone to test and repair.
Other else there not to much to do but try to reflash your stock firmware with Odin (this don't break your warranty), and do a full wipe from recovery after.

Yeah that's what I thought,I just tried if maybe anyone else is smarter than me and thought of something else to try before going to service center.
I tried with Odin already.Thanks anyway.

It's not Russian and same thing happens on 4.2.2 and 4.4.2
I returned the phone to the store,it returned from service but they haven't repaired it so i said that i don't want this phone anymore,i gave it back and demanded for a new one...now i'm waiting for a new one to come to my address this days
anyway, i think that there is a problem with kernel or something like that but it's up to the service to fix it not on me because it's a brand new phone

Camera suddenly acting strange

Recently I noticed that every photo I take, are low in details and over exposures
I dont know what cause it, I changed roms several times before I notice it, and after I noticed it, changing roms back to stock's, or custom ones, didnt fix it at all
In the attachment, I included a sample
Another strange thing is, even after I reflashed the stock kdz using lg flasher, some of apps from the previous roms still exist
Can someone help me ?
Thanks

Try flashing 4.1 first and then 4.4 KDZ.

I think I found the problem, overexposure happens when flash is in "Auto" and "On" modes
but If the flash is set on "torch" mode in opencamera (only opencamera supports this mode), there isnt any overexposure at all
any solutions beside reflashing 4.1 kdz ?

Need Help with Camera Please!!

Okay so i just got my lg g4 yesterday and its my first lg phone after many years of samsung. I installed a custom Rom right away but...
1. My camera keeps crashing especially when i toggle the manual mode
2. Also,i have noticed that there isnt any dedicated button for front facing camera in the camera ux,how can i get that?
3. I have tried other cameras,like G5 ported camera and v10,same thing.
Im running Imperium rom 5.0 with simplgx kernel.
----------------------------------------------------------------------------------------------------------------------
This one is abit off topic,but i figured id rather ask here than to create a dedicated thread for it....Whenever i apply a custom font,it doesn't take effect system wide,like in whatsapp and other apps,what can i do to fix that?

ill try to.. my internet connection is slow... actually its my neeighbors LOL.. and its rainning here...i think its 1mbt and itll take long time.. we get black outs only with samll rain or wind ... id suggest you download KDZ and flash it again..

Thanks but im at the end of the cliff.
Here's what i did:
1. Reflashed the rom like 3 times.
1a. I ported the camera from genysis rom,set permissions and rebooted
2. I flashed a different rom (genysis) with full wipes
3. I then flashed a kdz with lgup. Twice
4. I completely erased everything from the phone with lg up.
5. I downloaded 3rd party cameras (open camera and hd camera from play store)
Everything i did didnt bring back my front facing camera. I did a bit of searching and realized that its a common problem. Dang! A faulty new phone!!!

lenovo zuk z2 plus goes into bootloop after opening the camera

hey everyone
so i flashed lineage os 7.1 on my zuk z2 and everything was working perfect
after that i tried aicp 13.1 nightly and it was also working flawlessly but problem arrived as i used the gcam port for hdr+ in snapdragon 820 devices, initially the camera worked fine and everything was working normal but suddenly after some time whenever i opened gcam my phone hanged and then went into fastboot mode itself(the notification light is on ) and after i rebooted the phone it went into bootloop.
then after doing too many reboots finally my phone started and i changed the rom as i thought it might be a rom problem but in every rom whenever i tried to use gcam or even whatsapp default camera my phone suffered the same problem every time so i reflashed the stock zui firmware but the problem still persists as whenever i uses my stock cam or any other camera my phone goes into bootloop
when i searched the web i wasn't able to find a single thread related to my problem
really worried
please help
any help would be appreciated
*sorry i'm a noob to all this flashing etc*
also the bootloop occurs only after using the camera otherwise everything works fine
!!!!!!!!!!!!!!!!!!!!PLEASE HELP URGENTLY!!!!!!!!!!!!!!!!!!!!!!

Very strange issue. Dont know why that happens to you.
Which camera are you using? Try BSG port, v1a. Im using it and it works great. https://drive.google.com/file/d/1ubVpPrrZRkvVPH9qT7XzlttwcCVPxUcM/view?usp=sharing
Also try this, which i did also. Flash with qfil ZUI Oreo 243 version, you have thread for this, Jintu jose is OP.
It didnt lock my bootloader, and it didnt encrypt my phone memory.
Flash TWRP
Flash latest AEX Oreo
Flash GZR gapps
Magisk (you have to do it two times, once when u install rom, let it boot, than again flash in recovery)
Install google camera i posted and try.
This setup is working great for me.

I've tried every possible version of gcam but it happens always
Now the main problem is that I can't even use my stock camera app as whenever camera opens it goes into bootloop
I've flashed the stock ROM using qpst tool
But the problem persisted
Can anyone please tell me what should I do?
Is this a problem with my kernel?????
What should I do?
I am currently using aex latest version ?
Thanks for the reply but please help

Than I would say it is hardware problem man
If you have warranty, flash stock rom, I think 1.9 lock bootloader, and reclaim warranty
I say this because I never had this problem, ever, on any custom rom nor stock

Can I reclaim the warranty after locking the bootloader

Will let everyone know about the problem if I found one

the same thing that happen with mi zuk z2 but changing the rom to a another witch no uses the lineage os kernel solve the problem

I have the same problem the camera only works on the stock Android 6, maybe someone will find a solution for the guarantee it's impossible to hand over the phone purchased with AliExpress.

Hi, i have a similar issue with my ZUK, i have changed ROM, and after flashing it went to constant bootloop. i thought it might have been an issue with the rom, so i flashed again, but the problem stayed. Phone started and gapps were installed ok. It worked well for a bit and then it went to bootloop again (last time was when i switched from camera to video). I have formated data, to start clean, flashed rom again, but this time it got stuck on the ''android'' logo and doesnt seem to go further. Phone is recognisable by my PC and i have access to internal memory.

I have same problem now ...nothing working for me ..please help

Yes, unfortunately it turned out that the battery has been damaged and that was just nit enough voltage to startup the phone, I have replaced the battery myself for cost of approx 15 usd. It is very easy to open the phone ad replace it, as all tools are included with battery, you just need a hairdryer to melt the acrylic tape holding the glass back of the phone.

Sir but in my case I can go to twrp recovery easily, without any issues.
After your battery replacement the phone was back to normal self, i.e the room you previously installed was working without any issues?
Or did you had to use qfil and start from stock 2.5 zui and then re unlock bootloader and install twrp and custom ROM?
