Camera startup lag? (KK)

Hey everyone, I recently updated to KitKat on my phone, and I have noticed a strange issue.
When loading up the camera, whether in the default camera app or on a program such as snapchat, the following thing happens:
The menu buttons and the camera shutter button all appear as normal...
BUT the screen (the camera viewfinder) remains black, and everything freezes for a few seconds. Then the screen shows up the cameras image and everything starts to work as it should.
So it seems like the apps are asking for the camera, but the camera is taking a few seconds to actually boot up. Which is weird, right?
I'm not on a stock ROM, im on the RomAur 3.0 one, but as far as I can tell it is using the standard camera app, and noone else has had this problem. I cam from the previous version of RomAur and the camera in that didnt have any issues either.
Just wondering if this is some glitch or something is interfering? Any suggestions?
Thanks

Try to clean (wipe) all cache.

Had the same issue...
I did a reboot and the problem didn't happen again....

strangely enough this worked, even though clearing the cache and reboots were all things I did since I installed the ROM anyway...
I must have done something in the interim. Silly of me. Seems to be working now anyway so thanks guys

Hello guys,
I have the same problem, I did a factory reset which solved it.
But after some days it appears again, sometime it's working sometime not, it seems to be random...

Can confirm this.
Sometimes the camera app is working fine and sometimes it takes several seconds to start and it is laggy... :-/

If it lags, but starts okay, rebooting does fix it. No idea what causes it, but it's only done it twice so far.
The far bigger problem is trying to start the camera when it was locked, when there's every chance the camera will freeze and not take or save your picture.
Unlock first then start the camera and all should be fine.

Mine did this as well as other issues. A factory reset did not help but the thing that cured is was a "Repair" from Sony PC Companion. This will perform a factory reset and reflash the OS. Worked for me.

Resets, wipes or repairs won't fix it forever. In fact, I think it's something else that causes problems with the camera app and not the app itself. It's how you start the camera and what was going on at the time that matters.

This turns out to be right. After a day or so of no issues with the camera, I tried loading up instagram today and the camera took a long time to load up.
I also notice that even when the camera is loaded, if you try switching to the front-facing camera - that takes a long time to load up too. And same again if you try and switch back to the rear camera.
If this is standard on all kitkat roms for the Z1c then there is some major glitch in there somewhere.
So far it happens on standard app, instagram, and snapchat for sure.

Resurrecting my own thread, as I never actually noticed a fix for this to come up anywhere? I know im not the only one experiencing this, is everyone just living with it?
Its not a huge bother as when it crops up I can do a restart to fix it for another day, but if/when it crops up when im trying to do something quickly its pretty annoying.

I noticed this. Turn off location and it fires right up. That GPS lock can take a few seconds... especially if you're indoors!

I always have location turned off, at least the location toggle is turned off. Unless the camera is still attempting to use gps even when the service is deactivated? But then thats still a fault

Hmm, that's how I disable it... and I haven't noticed the lag. I should say, I am currently running a CM based ROM - PA.

Oh well then its unlikely to be the same problem, as CM (as far as I know) doesnt use the same camera/framework/etc as the stock sony.

I have the same lag on my Z1C (CM Nightly), but it only occurs the first time I start the camera after a reboot. I just start the camera once I have rebooted the phone (you can kill it via task manager again and it still works!) and do not have any lags afterwards that could prevent a quick shot. It's not perfect, but it works.

Same here with cm 11.

Then its a completely different problem, cos on the stock android after a reboot the camera is fast straight away, and its only after an indeterminate amount of time (hours/days) of running that the camera will then become slow to load. And then a restart fixes the problem.
Clearly CM uses a different camera, or some other different piece of coding, that isnt the same in the stock sony build.

I installed port camera from z2 and i dont have lags. On stock camera i had couple of lags and crashes but for now with new camera is good

Does the ported Z2 camera overwrite the Z1 camera? As in, will apps like snapchat etc use the Z2 camera code instead of the Z1 code?
Because the problem isnt just with the default camera app, its with every app that uses the camera. Snapchat, instagram, facebook, whenever you load up the camera on any of them, theres a 5 second delay while the camera screen stays black, until the camera then switches on and starts working.
BUT not all the time, after a fresh reboot they all work instantly like they should. Its only after a few hours or whatever that the camera starts misbehaving. Something is causing interference.

Chrome slowness / hanging

Had anyone else noticed hanging or lagginess when using chrome? If I look at this page as an example then it seems OK for a couple of second but then hangs unresponsive for about 10 second or so. Sometimes I get a message about chrome being unresponsive.

Something like Wikipedia is a really simple website. I wouldn't expect problems in loading it. My wife iPhone 5S is like lightning when browsing compared to this. Other websites behave in the same way...

only lag I ever experience....

I use swiftkey keyboard and sometimes it seems to start lagging. I'll type too fast for it to catch up and it's quite annoying. Other times it's perfect and very responsive. It seems like it starts happening randomly. I thought it could be a ram issue but a couple times it's started happening I've closed all apps and cleared ram and it doesn't fix it. I even cleared swiftkey cache. Any ideas? I should mention I type pretty fast.

Two diagnostic questions:
(1) When Switfkey starts lagging, do you also get a lag in the sound-feedback on the stock phone dialer?
(2) Does the Swiftkey delay go away if you turn off sound-feedback for typing?

You mean does the typing sound lag as well or just the sound if I open up the phone app and dial to make a call?
I did a lot of research last night about this and found others with the same problem... Someone said that if you clear your clipboard from the settings in your keyboard the lag goes away.. I did that last night and the keyboard has never felt father. How come that would cause it to start lagging?

Nope, the lag doesn't go away even if I have sound and vibration off. The only thing that seems to have made a huge difference is clearing the clipboard. I don't think it's placebo because it literally hasn't went into lag mode a single time since I did that.
Also, when it would go into lag mode, the keyboard lag wasn't too terrible ever in the messaging app built into the phone however facebook messenger, kik, and Google search were pretty horrible.

After more research I found more posts. Someone said having accessibility option enabled for nova launcher is causing this. I took about 10 screen shots and my keyboard immediately started lagging again. I cleared clipboard and lag fixed. I then disabled nova accessibility, took 10 screen shots, and it DID NOT LAG even with all of those in clipboard. I'm now convinced it's nova launcher causing this issue....

My Google keyboard keeps disappearing

Any permanent solution for that? I can clear data and it works. But it resets everything. And after a few days it disappears again. I can actually type but I see no keyboard.

I had the same problem on my Z Play with stock 7.1.1 (soak test). The Gboard disappaer and goes black. I have then force close in Settings, Apps, Gboard. Then it working again for a while.
Now I have switch to LOS14.1 and the problem isn't come again. Maybe the final release of stock 7.1.1 fix the problem, too?
But I really don't know if it's a rom problem or an app problem.

I get this too a lot. Never happened when I was still using my LG G3, but ever since I switched to the Z Play it crashes sometimes or the keyboard just stays black.

But that's a software problem. On LOS14.1 I have not this issue. But here is all newest now That's feels so good
And would be interested to know if the problem by Motorolas Stock ROM or by Googles Gboard.
And I see that I have gotten the newest version of Gboard with the latest Open Gapps. Maybe it's enough to update Gboard? Otherwise moto has the bug in her firmwares.

Just enable Force GPU rendering on Dev settings and will be fixed

I would say that's the problem is by Gboard. Would try to update Gboard first. Then we would know exactly.
But don't know. Try Gboard update, then we see.

Had this problem also , seems to be solved with the latest gboard update a couple of days ago.

Me too. Started about 2 months ago, When starting Google search the keyboard appeared, disappeared, appeared. I often typed in an area exactly when the keyboard disappeared. Sometimes it seems to have crashed, no keyboard to see, needed to switch to a different keyboard and back to re-enable. Was happening about every second day. Then I found it it is active, but invisible!
All that crap ended last week after an update. Hope all the issues had the same reason which got fixed.

Not all issues are fixed. When activating Google Search bar, the keyboard sometimes still appears, disappears, appears. It's a really bad timing because every second time I start typing exactly in the moment when it disappears for a quarter second, and thereby deactivate it and start something else whatever is under the key I press (maybe the second key press if the first got used by deactivating, dunno for sure).

Screen Flickering

Hi,
So I offer this phone to my wife this xmas and everything was going smooth until we found this issue:
https://www.youtube.com/watch?v=xYFdyDwuS_w
The bottom screen does this flickering when typing with Swiftkey keyboard on some apps. This one is Doggcatcher but it happens on other apps too.
If I swap to GBoard it does not happen. We're on Android Pie 9.0.
Has anyone found this issue?

Seems like a graphic bug in that specific keyboard.

Please, i need help.
Evaluate for yourself whether it is related to this topic.
Occasionally, graphical glitches appear on my Mi A2 lite, (4/64, Android Pie, December update, locked bootloader, no root, intact system).
In most cases, they flickering all over the screen, and in some other cases they are frozen, as is shown in attachment.
They are completely random and they appear through many applications that i use.
I can not determine the cause.
Does anyone else have a similar problem?

me... on chrome and all app that use webview... during call status bar is flickering... when switch to the camera in whatsapp with swipe to set status... and other

Something similar here, if Facebook Messenger chat head is overlaying YouTube it flickers a lot (only the actual video but the description and recommend are always working without flicker also no problems in fullscreen), less often it happens with Chrome and sometimes YouTube does it without Facebook Messenger even being open (Android Pie Dec. 5) [also it didn't happen for the first few weeks with 8.1 then Pie got released and worked well for some days then this started to happen]

I have that problem , the notification bar flickers a lot and when on video calls, it shows a black flickering rectangle at the bottom of the screen

Hi, I've got the same problem here. For me, the flickering appears when the keyboard is open, and get faster while typing, please does someone know how to fix that?

It is true that it is the keyboard, my keyboard developer is fixing the bug making it do that as we speak but in my case the whole screen flashes black instead of the little box you have

The problem with the flickering screen in some apps like Youtube, Chrome or Instagram can be fixed as follows:
Go to Developer Options and activate "disable hw overlays"
However, the setting must be set again after every Phone restart.

Isn't that bad long term?
"Without a hardware overlay every application that is displaying things on the screen will share video memory and will have to constantly check for collision and clipping to render a proper image, this can cost a lot of processing power. With a hardware overlay each application gets its own portion of video memory, getting rid of the need to check for collision and clipping."
