[Q] The stock 4.3 - 4.4.2 camera bug - Nexus 4 Q&A, Help & Troubleshooting

Hello, after I started using Snapchat I noticed pretty big (and extremly annoying) bug. When I use Snapchat on my Nexus 4 with stock 4.4.2 android, it just randomly restarts the whole phone, sometimes it happens after a longer time, sometimes almost instantly after I open snapchat, so this bug makes snapchat absolutely unusable on Nexus 4 :/ So I've done some research and I found out that it's a software related bug that many users encounter since 4.3 and it's related to some bug in the camera API (so it's not snapchat's fault).
Well my question is if this can be solved by using custom rom, or if someone made (or is going to make) some fix that I haven't heard of, because obiviously Google doesn't give a sh*t about their ex-flagship phone
Nexus 4 is awesome but this bums me alot...

I am not sure but this issue is fixed on semaphore kernel. You might check it's thread a for more information.

[Q] Strange screen issue with reboots

Hi.
I'm new to Nexus 7 and after a short time using it I began experiencing some strange issue with the it. While surfing the web over WiFi (note that I'm using the first Nexus 7 with WiFi only) after a short time glitching lines appear on the screen (as shown on the image attached) and some loud white noise coming from the speaker. It's stuck like this for about 30 seconds and then reboots. After reboot, everything seems normal, till it comes again. It takes 15-30 minutes of surfing and I believe the time depends on the intensity of surfing. Seems like WiFi modem somehow affects the GFX driver.
Note that I was first running android 4.1.1 and recently updated to 4.2. Updated didn't fix the problem. I've rooted the device with "Nexus 7 root toolkit v.1.5". Note sure if the rooting affected it somehow, as I rooted the device on second or third day of use.
Anyone have an idea of what could be wrong or how I might fix it? Or it's HW issue and I should turn it to Google?
Thanks!
So I'm the first and only one with such problem???:silly:
I could be wrong here but that seems like more of a hardware(warranty) kind of issue. However, I had the speaker issue after flashing a custom ROM (sparks linario 4.2.1) and I had the speaker issue (along with a host of other bugs buts that's beside the point). I flashed stock and unrooted and the problem was fixed... I know it might not help your case but I thought ide let you know. Its possible the toolkit caused the issues and flashing back to stock and rooting with another method may solve your issue (that's what I would try). But if you end up sending it in under warranty for god sakes, unroot and relock your bootloader first! Otherwise Google probably won't honor your warranty.
Good luck friend.

always had problems with camera app

Ever since i bought my i9500 the camera always has lag or 1 or 2 seconds delayed problems. This happens everytime no matter what rom or kernels i use, lately i been using omega v10 with adam kernel, but the camera seems to have lag or 2 seconds delayed when it finally opens. It just seems to not work properly when i needed it.
Does anybody know a rom or kernel that fixes the camera app? I really want it to open quickly, with basically no shutter lag...if that's possible.

[Q] Nexus 7 sound issues post 4.2

Greetings,
I bought a Nexus 7 and it came with 4.1.2. No issues at all, and when the upgrade to 4.2 came I was stoked. After initially upgrading to 4.2 some time ago, I noticed video and sound would periodically stutter and crack every now and then while streaming Netflix. Recently, after 4.3 was released, I gave it another shot and it still has the same issue. This issue does NOT exist on the 4.1.2 stock rom (for me). I have tried a non-upgraded clean flash of 4.3, along with attempting to disable (i believe it's called) prism through trickster mod, as well as disable google currents, as well as 'Lagfix' app. I have tried unticking the wifi setting that increases battery performance, and I have tried forcing GPU to render the screen. The only thing that seems to work, which unfortunately forces the Nexus 7 to get really warm in its case and have terrible video life, is forcing GPU to render the screen in the developer settings.
I will mention that the video flicker goes away with the trickster mod option disabled, but the sound stutter-crack still continues. Again, this DOES NOT HAPPEN on 4.1.2, and while that is a very solid stock ROM, I'd like to be able to update my device at some point in the future as I cannot find anything that helps alleviate my case. Thanks! Any Idea what I can do to fix this and enjoy 4.3 and possibly future releases? Thanks

Skype & Kitkat issue

Everything was perfect when i was on Android 4.3, any skype calls working, video/audio doesn't matter.
But when i updated my wife's phone to kitkat, some skype calls making phone reboot(black screen, then its loading as usual).
It happens not always. And i have noticed that it crashes only while talking to people who have Windows XP installed(with latest version of skype, checked & updated myself).
When she talks to anyone on 7&8 Windows - everything is perfect.
I have tried all custom roms, original, rooted\not rooted, anything.
I gonna write this issue to Skype too.
Skype support asked that Skype not supporting KitKat yet.
Btw it only happens on Nexus 4, when i'm on my phone (XT910) on KitKat, it works and not hangs.
In my case occurs the same...I believe is maybe kit Kat by itself and usually happens when I leave a call in the background while I use another application. Unfortunately I haven't found any solution for that.
i have noticed that it crashes only while talking to people who have Windows XP installed(with latest version of skype, checked & updated myself).

Not really. The problem is a bit more serious: all ROMs (stock and custom) based on 4.3 or 4.4 are affected by this overly annoying camera bug. I obviously hope you're not, but if you end up as unlucky as I did, your camera and LED flash will soon become totally unusable (on all applications), fixable only by reverting to 4.2 or updating to L (I did and it's totally worth it)
Good luck :good:
Also another issue with Skype and N4 is that whrn listening to music and an image is being sent / received in the Skype chat window, fetching that image from the gallery/disk causes the audio system to crash. It's really annoying. Probably it's the same issue as the well-known audio stutters on changing connectivity and high cpu load.
Im using the Verizon G2 and running 4.4 2...xdabebb rom..i use skype a lot for business calls and havent come across this issue at all. On unrooted stock as well as custom. Ive also faced no issues on an S4 i9500...so it might not really be a kit kat issue but a nexus 4 specific...or an aosp based rom specific issue

I have another kind of issue with my xiaomi Mi2 with MIUI Rom on kitkat 4.4.4. I have systematically a black screen when the communication is established on Skype also using test sound server. The sound is working but I can't do nothing with the phone until the end of communication decided by my correspondant.. Very annoying . I have post the question to Skype 5 days ago but no answer. Skype was working properly on my phone on miuiv5 android 4.1.2

I'm having the exact same problem ... I was talking on Skype video call and the phone screen went black and I couldn't hear the other party.. I don't if they were able to hear me or not. I had to hold the power button and reboot my phone manually. I don't know what the problem is but its very annoying and it happened three times in a row. I have used multiple ROMs and it was happening on all of them and they were all 4.4.4. I don't flash kernels, I just use the kernels that come with ROM because they have obviously been tested and have been found compatible with the rom. So I know its not because of kernels. Currently I'm on Slimkat latest weekly and was thinking about going back to stock but someone said its also happening on stock ROM. I'm going to try CM11 and see if it happens there as well. Will report back soon. Hopefully it's just a 4.4.4 issue and not a phone issue.

Display problem

Hello there.
I'm proud new user of Nexus 6p but I already have a problem. I updated it to 7.1.1 and rooted the device. Now chrome constantly crashes (Aw snap problem) and also facebook sometimes show strange image.
Screenshots attached.
Anybody else have this problem?
i love my 6p and am also a proud owner of this beast.
but i also have troubles with my display, it is abit similar to yours, i have occasional graphical glitches and it always freaks the hell outta me.
i hate those glitches , i had a split screen bug on my Moto Nexus 6 as well and using a specific custom kernel called Lean kernel always solved that problem for me.
but currently nothing fixes this on my nexus 6p , except the 6p of mine thankfully does not have that split screen bug but instead it has some other occasional hiccups with graphic glitches.
and i think it is because of the cold temperatures, but i am not so sure.
Cold temperatures can't be a problem with mine couse i work inside so there is no cold
I tried with elementalX kernel and the problem is still here.
chrome gives me the most graphical glitches , but it does not happen often.
it can still get annoying , and i also have a keyboard issue with chrome (been months now) the keyboard issue is, i cant delete characters i have enetered in the search fields of whatever website i am at.
like when i press backspace to wanting to delete words it just wont do it, annoying bug with chrome i am sure of it, as i have tried other browsers and they dont do that with the keyboard backspace not deleting characters.
maybe we should both switch browsers, but the thing is i always go back to chrome :l
hope your issue gets solved too, maybe try a custom based nougat rom and you wont see that issue with chrome anymore (as for the fb app, it is a battery killer i would advice to just use the chrome app to open up your fb account).
Tried with firefox but the problem is still there.
Will try and get myself different rom for weekend and test it.
So you say that facebook is battery killer. Thanks for the info.
Update:
Installed Pure nexus rom - problem still there
Installed CM 14.1 - problem still there
I have no idea what is cousing this problem. Is it possible that the problem is hardware related and not software?

Navigate to Settings/Developer Options/Webview Implementation then switch to "Chrome." See if you still notice these issues.

Nope I think your display driver is glitching
I'm taking it back to the store today and they will replace it with the new one they said. Hope i'll have more luck this time
