Touchscreen slowness

Ok so i am trying to determine what my problem is.. here are the symptoms. When i try and end a call i sometimes have to press multiple times or deliberately press and hold the end button and sometimes it doesn't respond pretty much at all. Also i am using go launcher and when i press icons that are in the dock bar they have the same issues. I also have similar issues when i text it's really annoying so is anyone else have similar issues?

Same here. I've noticed that to hang up it takes a deliberate double tap. Also, the screen will sometimes become inoperable requiring a reboot. This has happened three times since first getting it. One note if that out happened twice stock, and once with decrapped 1.1
Any body else seen this?

I haven't seen it anywhere else, but I have seen the double tap on the end button to end a call. Seems to happen frequently. A "feature?"
Either way, it's annoying.
Running Go Launcher as well.

To me, it seems like it takes the screen a really long time to wake up from being off, in all cases - for example, dial voicemail and put the phone to your ear. When you get the prompt to put in your PIN, take it away and the screen comes on, try to punch the dialpad button immediately and it just won't work. I tried it as I was writing this and had to triple tap the button.
Same thing with the lockscreen (still on the stock lockscreen for now). The screen will wake up and it takes a second or two to even start to register finger swipes. It's really annoying...
Speaking of phone lockup, I received a call a few days ago and the phone froze - I couldn't answer the call, or do anything, all the while the phone just kept ringing. Had to pull the battery. I'm still on the stock ROM.

Me too! I had a call and it froze. Battery pull as well. Also, forgot to mention I am using open home launcher.

Yep it's a bug either in LG's function to turn on and off the screen in Android, or the kernel drivers that enable/disable the touchscreen. There is about a 1 second delay to it.
I discovered this lovely bug while porting the AOSP lockscreen mod.
I'll run some more tests to see whether it's an android bug or a kernel bug. I'm betting it's android (something like the screen being turned on before the touch controller has had time to reinitialize itself, or something more complicated like a race condition of some kind...)
Either way, with cm7 around the corner, I don't think it's that big of a bug

Errrr Are you sure the Revo is getting CyanogenMod 7? Where did you hear this and more importantly when will we get it?

Since he is the one working on getting it ported over, I think he has the best idea, and the only rule of cm is no asking for etas ;-)

Home button lag in Android 4.4 (KitKat)

Open any app eg. dialer.
Press home button. There is a slight delay (the amount of delay seems to vary at random) and then it closes. Sometimes it's not noticeable, sometimes there's a half a second delay.
When it does happen, you can see the home button light up animation stuttering too.
Compare this with the back button.
Open app again
Press back button. It closes instantly every time.
This is repeatable, and happens with every app.
Edit:
There also seems to be added delay to the multitasking button.
When pressed at the home screen, it's there's a small amount of delay. When pressed inside an app, there's a one second delay.
Using ART runtime seems to fix the lag in home and app switcher buttons, though 4.3 did not have the lag and it was dalvik, so not sure what that means.
Pulling down the notification on lockscreen also lags. But I do have the transparent system bars mod so it could be that.

doesnt happen on my phone

hmm.. happens with me too. stock 4.4 with TWRP

You overreacting.

I see what he means.. I wouldn't call it lag, just delayed.
I did a screen record of it. It's so minimal I would never have noticed it until my attention was called to it
I have animations disabled

Not to sound rude but... this is a complaint? I get that the transition animation might look like crap and a tad choppy. In that demo at least, it does. But come on, just turn the animations off if they bother you. I've got an iPhone 5S, which is by most accounts the smoothest mobile experience, and clicking the home button takes the same amount of time (probably longer) because of the stupid fade in/out stuff.
If your complaint is a freeze up, then that's valid. But as an aside, I'm with you in that these animations are getting borderline cumbersome and stupid. The "lag" you see is Google's need to utilize these things.They used to be cool, like the first 1,000 times I saw them. Now they're just a lame hindrance to opening an app.
Sent from my Nexus 4 using xda app-developers app

Actually has nothing to do with transition animations.
It is the delay with the home button press being registered, before the animation even starts.
And actually in the video recording above, animations are off.
This is a regression. In 4.3 the home button was much more responsive, so yes it's a complaint. Actually, not really. I'm just putting the information out, and also want to see if others are experiencing the same.

I'd love it I'd you could stop watch these findings to display this massive regression.

Out.

I was actually just hoping you would get out a stopwatch and show the difference with some stats...I mean maybe it is an issue.
Sent from my Nexus 4 using xda app-developers app

I am using factory stock with AOSP launcher (launcher3.apk from CM11) and ART enabled, don't have that problem, its very responsive.
Don't watch this if you suffer from epilepsy.
I guess sometimes there are 100ms delay, but its not abnormal. Delays tend to be because its trying to launch a new app.
I just tried Google Launcher and its not an issue either.

This should go without saying but... I'll throw it out there anyway. Because... Yeah...
For anyone watching the screen record I made.. You have to remember the overhead encoding video and writing to the Sdcard will have on the end result. ie: Performance in video may not be a complete accurate representation of real world use.
/I just wanted to use screen record and this looked like a opportune time.

I've noticed the same thing on both 4.3 and 4.4. Captured a video of mine and streamed it to Twitch since it's one of the few places that accepts and plays back at 60 FPS: twitch.tv/caiman86/b/479853664 (won't let me linkify it since I have too few posts)
Sometimes the home button is perfectly responsive and sometimes there's that strange hitch and delay when going home. The video showcases this fairly well.

That video shows the issue pretty clearly. Link (since you can't post a direct link)
Though I can't say I remember having this issue on 4.3. I could be wrong. My girlfriend has a Nexus 4 still on 4.3, so when I can get my hands on it (probably tomorrow), I'll confirm.
But even if it was in 4.3 and not just a new 4.4 issue, I still think it's worth reporting.
Also I don't actually know if this is specific to the Nexus 4. If anyone has a Nexus 7 or 10, could you please test if it happens.
Thanks.

Have you ever had a go on an s3? I had a go on my dad's and there's a huge wait after pressing home and anything happening, although admittedly this is because you can double tap home to open something (s-voice I think it was)
Sent from my Nexus 4 using Tapatalk

On S3 you must disable option (double home button klick action) in Accessibility.

On the iPhone it's almost instant whereas on Kitkat it's quite laggy.

Yep, it's because of the double tap command, not the same issue as this.

You are right. The delay is quite noticeable.

[Q] Severe wake up lag

I've had fairly severe wake up lag on my Note 3 since the beginning, 4-6 seconds is fairly common (6 seconds means it flashes the screen and blanks it out again, going back to sleep, but then I can wake it up again and it responds in 1-2 seconds). I've never seen this on my Galaxy SIII with the same set of apps, but as soon as I got the Note 3, I saw the delay. I've swapped out for a new one (different reason) and see the same behavior.
If it is not common, I'd have to attribute it to an app...but honestly this is a base OS function, no app should be holding the phone in deep sleep. Any ideas would be helpful.

KitKat appears to fix this

I don't got 4-6 secs lag, but I did have 2sec lag, and then took out my SD card and that fixed it for me.

i had a 64gb class 10 sd card i got for 15 dollars. 64 is kinda over kill for me. but yeah i 32 gb is enough for me, i still got like 18gb of free space left lol or something like that.
edit: but apparently the the guy up there said kitkat fixes that.

Wow, good call! My first Note 3 had the proximity sensor go bad, and then stopped recognizing my SD card. I figured the phone was just a lemon, so I transferred the SD card into the new phone and it didn't recognize it either so I just left it in. After you said this I removed the SD card and it's vastly improved, so far it's back to the normal 1-2 second lag max (so far).

I had the same thing with the sandisk card. replaced it with Samsung's version and its resolved.

If you are rooted, i would advise you to use the Vulpix Mod. It works!
http://forum.xda-developers.com/showthread.php?t=2584013
it has helped me greatly reduce the wake time. though, its been months since i flashed it and i believe the wake time to be gaining again.

The update to NB4 pretty much eliminated all lag. I can click the lock and wake button all day and it instantly goes on and off since the update.

I was running the Crash rom port yesterday and I thought my phone had died. I was receiving an important business call on my work phone and at the same time trying to wake up my Note 3 to see my notes for the call. I was pushing the home button and nothing was happening. I pressed the power button and it woke up. So kitkat did not fix it for me. Now I'm trying Knoxraid rom and am noticing a short wake up delay, I may try taking out the sd card. I'll report back this afternoon.

im on knoxraid and i havent seen any wake up lag. make sure your sd card is out and s voice wake up commands arent on. those are the main causes from my experience

Unresponsive power button

Has anyone had any power button issues? Or heard of anything similar.
Suddenly found that the power button was completely unresponsive, in that it wouldn't wake the sleeping device, fortunately I'd enabled volume buttons to wake, once device was awake, power button still did nothing, so I couldn't get to access reboot menu, so installed Franco's reboot application, rebooted, and it's working absolutely fine again? As if nothing was ever wrong, makes me suspect a software rather than hardware related problem.
Strange? Familiar? Can anyone relate?
I've had many previous, non nexus devices which suffered from dead power button, but nothing of late, plus the device is only weeks old.
I'm running latest Chroma build (as per sig) so asop.
Sent from my Nexus 6

Not exactly experiencing the same problem, but I've been having this odd power-button issue since today. If I leave my phone locked/screen off for about 5 minutes, it does not respond to a press of the power button. The weird thing is, it does respond after exactly 3 presses, every time. It's a non-issue when Smart Unlock is engaged on my home wifi-network. On 5.0.1. Chroma, haven't updated it in a week or two.

Happened again, dead power button, woke by volume buttons, reboot, works fine again.
So this isn't intermittent, in that when it fails it won't work again until restart, which says to me software.

Do you have a screen protector covering the sensor? If so that's probably the issue, disable ambient display and see if you can reproduce the problem.

No screen cover, just a ringke slim cover. But I don't think that covers the sensors.

actually i encountered this issue even after a reboot...
but most of the time it would go away.. i really wonder why is this so.. my power button is confirm working fine because it allows me to do a force reboot (by holding on to the powerbutton for like 5-7 secs).
using 31/3 chroma.. didnt experience this from stock or terminus rom..
have you all tried a clean install?

I would get this issue on Chroma if I had enabled the option Display--Ambient Display--Overwrite Value.
See if thats enabled, and if so, try with it disabled for awhile.

I was clean install on 5.1 but not since, although did import apps and data from TB not that it should impact it at all. Only ever run Chroma, jumped straight to it after initial unlock.
Fortunately volume keys always wake - so far.
Let me know how you get on - in this thread.
If I find it continues to happen then I'll consider clean install and then maybe even a replacement device.

Everything was fine after last reboot.
Immediately after plug in into charger, the power button stop working. First time experiencing this. Able to try this to guys?
Edit: I toggled 2 things.. Enabled / disabled ambient display overwrite defaults and screen on when plug / unplug charger..
Power button is working again without any restart.. @githyanki @ben_pyett

Recent Update

Anyone having any specific issues with the most recent update?

Well my wife has been using it the past couple days and got the update at work yesterday... Today she mentioned the Home button notification light doesn't seem to be working. (it was when I first started using the phone) I'm not sure if they are tied, or if she messed with a setting. If anyone else who got the update would like to test the notif LED on the Home button that would be cool.

hardware buttons issue
The notification light for me is fine but my hardware buttons are testy. sometimes I have to double press the buttons for it to respond. Other times the entire phone freezes for a minute or the buttons don't work at all. I think it was a bad update.
Some days later the phone stopped getting text messages until I restart it. Now it gets them hours later. I already cleaned out the cache. But did not fix it. This update is killing my phone.....
