Touchscreen response jumpy/laggy with Angry Birds on A70

As the title mentions, touchscreen response on my A70 seems laggy or jumpy when playing AB.
Basically, when trying to do the fine adjustments to aim, the A70 wants to jump around several pixels worth of movement. (sometimes up to about 1/4 the hight of a bird) On my Nexus 1 and G-tablet I could adjust aim down to pixel sized movements.
It may be due to being close to the screens edge, but I was wondering if anyone else has noticed this. It is not a constant issue, but touchscreen response definitely seems less precise all around when playing the game. Most other apps I use do not need such fine adjustments, so I can not tell if this happens in them as well.
Edit: Downloaded a multitouch tester. (multitouch vis test) This app plots your finger with x,y cords and a visual dot. When moving slowly, both tracking methods made small jerky hops rather than following my finger smoothly. I have never had this happen with any other android device. And yes, I did try the screen calibration in settings several times.

No one else have this problem?

I have this as well... pretty annoying.

If this is common, then thats unfortunate. If it is rare then we know that we need to talk to archos support.

Are you in fw 2.0.71 ? I think is firmware related problem. I downgraded to 2.0.54 and have much fewer problems. And a faster a70 (z4root and SetCPU 1000mHz)

Hi there, first Message from me and first Touchscreen device...
i think it is because the wires of the touchscreen are not so close together.
When i look at them, the distance of them seem to compare to the "jumps" you mentioned.
But i have no other device to look at.

Are you using an App Killer before starting Angry Birds? I use the System Monitor to kill all unneeded applications to get at least 90 MB of free RAM before started Angry Birds and it runs very smoothly with excellent response from the touchscreen.
Bye.

No, but the multitouch test app is not a RAM heavy app and it also has this problem.

please try: Settings->Repair->Touchscreen Calibration

Hi _nz_
Did you read the op last sentence.
"And yes, I did try the screen calibration in settings several times."

I have noticed this same issue on my 70.

Hmm, maybe I should start a poll. Try to get a rough guess at the ratio of those with and without this issue.

I also have this problem with my 101. Sometimes the game has frozen completely. I mean freeze as: the screen freezes but the game continues. I can hear the audio still. If I am firing off a bird it will freeze and I can hear the bird continue to fly and break things but can't do anything about it. I have to exit the game and then jump back in. Really annoying when you are at the last move to beat the level. :-( There doesn't seem to be any fix that works for me of the things I've tried. Very frustrating. Still love the unit though!

I don't see this issue on my 70. I'm not too good at ab though, maybe that's the reason.

I see the same issue on my 101. Hard to make fine adjustments.

Agreed. Kill other apps to gain more memory before playing AB. It will then plays smoothly.

This has nothing to do with the game not playing smoothly. It is about touch screen response. I have the same issue when using a 150kb multitouch visualizer app on a fresh reboot.

Is the homescreen choppy for everyone?

I went to best buy a little while ago and they had a XOOM display sitting all by its lonesome getting no attention, so I went over to play around with it. The apps seemed very snappy, but switching between homescreens and flicking some of the widgets was quite jerky and choppy.
Is this everyone's experience, or was it just that one XOOM?

I haven't had problems with chop. I have noticed very minor stutters with some 3D effects, but they're barely noticeable.

My experience has been buttery smooth man.
No chop

Same here. Everything has been very smooth!

Interesting. I wonder if it was because it had been left on since 10am.
I even starting trashing widgets from the home screens until all that was left was a few app buttons. Didn't help any.

Mine is fine. The only thing I have noticed it that the screen rotation is slow.

Screen rotation has always been slow on Android. Doesn't bother me.

Screen rotation on my infected evo is very fast. Almost too fast. Just Ned to wait for virus to make xoom roms. Won't happen but would be nice

It's choppy/jittery for me using Dolphin Browser. I'm still playing with the thing, so I don't know what else is doing it.

When I put my Xoom in portrait mode, it is laggy for sure 100%, but in landscape is smooth.
Anyone else seeing this?

It's normal, Dolphin isn't yet accelerated by the GPU, like the Chrome browser.

Pretty smooth for me, I noticed a bit of choppiness, but it appears to be random.

I wonder if the demo unit at Best Buy is different. I know that it lost wifi connection with Best Buy's routers while I was there. I asked someone about this and they said it had something to do with the demo unit. Whether that was true or not, IDK, but it worked perfect with tethered to my phone over Wifi.

Laggy after 4.010.13 update

Has anyone else had lagging like turning up the volume the volume bar would lag?

Everything seems to be working ok havent really noticed anything really.

I haven't noticed anything either, although, admittedly, its early in the game.

If this is the 2nd update, then yes I am noticing some lag. Especially when doing things like you mention which totally frustrates me 'cause it was these types of activities that got so much better with the 3.1 upgrade... at least for me. Smoother swipes between home screen, moving widgets and a few others... sigh
Oh well, just hoping 3.2 will fix these. Asus is getting it this week, please Acer keep up with the Jones on this stuff!

Mine got it a few days ago. During the 2nd reboot, it was stuck with the screen backlight on, but nothing showing up. I had to force it off, then back on. I did get the "update was successful" message after unlocking it. Since then, it seems to be a little slower, especially with screen draws. It still plays videos fine, but the more apps I have open, the slower it changes screens, for example.

I noticed mine was laggy after the update... I thought maybe I installed something that was eating up the CPU, but I think it was probably the update that did it.
It's not horrible, just annoying.

Me too I have been some FC with launcher in addition to the laggyness.

I've had some lagginess, but only after I installed several apps. Skype was one that kept running, so I uninstalled it. Not sure what happened, but I only noticed lag after a few days of running and installing several apps, so I'm having trouble pinning it down.

I just went and backed up my apps with TB and factory reset and restored my apps back and no more lag

stutter when scrolling slowly

I've noticed that when making a slow even scroll through any app the movement is kind of jittery/stuttery - kind of like a very rapid screen flicker (but different to the screen issues posted elsewhere as the brightness setting is not a factor). It doesn't happen on any of my other devices. Don't think it's a processor issue as games/videos are flawless. Has anyone else noticed this or is it just me?
On a side note, white backgrounds seem very yellow (see attachment) - especially compared to my OG transformer. It's not a massive issue and i appreciate this is a budget tablet - just wondering whether this is normal or if it's a fault.
thanks.

I'm seeing some stuttering on Google+ that I really notice.
Sent from my Nexus 7 using XDA Premium HD app

I notice this stutter in chrome all the time. Very frustrating.

I get stutter swiping from image to image in QuickPic, some microstuttering in Google+ in the What's Hot section.
Maybe some apps aren't GPU accelerated and the CPU is a bit on the poor side to handle it?

Have you also noticed that the yellow background is easier on the eyes? It was done on purpose, because this was built primarily as a kindle fire competitor..
As far as the scroll stutter, its Chrome. Try Opera or Dolphin and check back with us. It does the same on mine. Dolphin, Boat, and Opera are better browsers. Try them all out, I think you'll find happiness with one of those!

I have a lot of stutter in google play store,chrome and some time in games as well. It happened in dead trigger. plus when am not running any apps in the background and i go to settings,battery i see lot of stuff there like google play,chrome,dolphin browser,picspeed wallpapers and many other stuff as well. and the cracking sound that it makes on my right side of the screen. I opened the back and tightened the screw still no luck still makes noise. i can only think that the back case is making the cracking sound. Plus my jelly bean is not butter smooth like most video i have seen. I was thinking of exchanging it but am thinking if i do that i might get a even worse one. Google really need to give another update soon that fixes some of these problems

As i said, it's not specific to any particular app, it happens whether in maps, browser, menus etc. unfortunately.
Tried hw overlays; no joy i'm afraid.

This happens everywhere during any slow touchscreen movement because of a crappy touchscreen controller and crappy filtering algorithms. The app is just scrolling to wherever the touchscreen tells it to (which is to random points around your finger tip several times a second) and this makes it look like it's jumping up and down or microstuttering.

Weird lag

Hi everyone,
My note 4 seems to start lagging recently after I play games on it for a while. When I close the game, the phone itself lags as well. It's very obvious too when I'm just scrolling through my drawer. Has anyone experienced this? The few times I noticed the lag was also when my battery was low, <25% and I thought it may have been power saving mode. However I checked and power saving mode was off. Also when I use the facebook app any anytime, it has a scroll lag. I noticed that too when I'm browsing on certain sites (ie; XDA).
I tried factory reset and that did not fix the issue and I have the phone too long to exchange/refund

Dont worry bro
Use nova launcher for best experience

same dam problem

I am having the same problem.intalled Nova turned off s voice. UGH PLEASE HELP

I never experienced any lag using stock launcher!, i want to stay my phone the way i first bought it.
if i change my launcher it feels like im not using note 4 anymore!

I'm already using nova. I tired stock browser but sites like XDA still lags when I scroll. Also when I game for a while, the game will start to lag. When I exit to home screen the phone itself lags too! I have to clear the ram for the phone to go back to normal. The weird thing is, the ram was only 2.22gb/2.72gb, it's not even close to max!

Stop clearing your ram now
Try uninstall some background app like facebook and see the effect

Hm interesting, after I last cleared my ram. I've been gaming for 2hrs straight and 0 lag... I've swapped back and forth from game to homescreen to whatsapp etc and no lag at all... Only thing different is I'm charging my phone at the same time. Think charging has something to do with it?

Just got myself an exynos note 4. Very nice phone but aside from a little touchwiz stutter, games such as real racing 3 and clash of clans stutter. My nexus 4 ran them fine. Did a quick antutu benchmark to see whats up and i got 49000 on antutu without flight mode on. What do you think? Benchmarks say my phone should handle them with ease but thats not the case. Anyone with a solution? I already disabled many samsung and google apps. Lag is evident only in games.

You're not using Power Saver, are you?

My note's benchmark seemed normal and I play Clash of Clans as well and it seems okay. The game I play most often is Summoners War and that is what's causing the lag. Come to think of it, I think I had an issue with the lag on my Nexus 5 as well but I might have chalked it up to the phone being old so when this happen on my brand new note 4, it raised a red flag. But still, I'm still confused why the game would lag my phone even thought it there's plenty of memory available.

I just tried clash of clans on my brothers s5. Turns out the stuttering is even worse. Im testing this by zooming in on the base and scrolling rapidly back and forth on a canon for example. I will test this on my nexus 4.i too thought coming to a phone as powerful as the note 4 i shouldnt see any stutters but if its happening on an s5 then i guess its not a hardware issue on my phone but rather an android thing? Tested this also on my iphone 6 with no stutters at all.

Nevermind there is definitly something wrong with my phone as clash of clans looks like its being played on a 5 year old phone.way to many stutters.

I was having the same problem, so believe it or not, the way I stopped it was going into application manager and disabling S Health. I don't know how or why, but this stopped all the lag. After installing Ktoonez kernel, I thought maybe I could turn it back on, but when I did, I started getting the same lag again. I hope this helps because I know it is frustrating

I second Keith's recommendation. My 2-day-old, rooted Note 4 was lagging and was particularly noticeable when scrolling through some web pages or content in Flipboard. But it lagged in other places as well. Also stuttered or paused when playing podcasts. I tried installing Nova Launcher, I tried removing Wanam Xposed, and some other things but it finally went away when I started to disable various Samsung bloatware. The success occurred after I disabled SHealth and some other things (I just happened to do a few all at the same time). I suspect SHealth was the culprit because it was probably running in the background all the time, trying to track my step count.
I ended up keeping Nova Launcher since I gives me some useful customizations, and I love Wanam + Xposed, partly because it lets me get rid of Samsung's Search menu item that always used to appear in my notifications shade.
It's been over a week, now, and no more lag / stutter. Absolutely loving the phone, now.
I haven't gone back to re-enable some of the bloatware in order to confirm that SHealth was the culprit because, quite frankly, I have no interest in the stuff I disabled, anyway.

I have also disabled S health but I never had a problem with Clash of Clans when even I had S health Enabled.. whereas the other game I play (Summoners War) it always start to lag after an hr+ of gaming.

I already disabled s health through the app drawer but that does not solve the problem. Coc will run fine for a few mins and then start to stutter like its not optimized. To test for hardware issues i installed dead trigger 2 and injustice gods among us and they absolutely fly. The problem seems to be with coc. I am using an exynos note 4 on stock rom stock kernel. Any thoughts?

return your phone

when your phone starts to stutter after some time playing games, it might be thermal throttling. depending on the game you can notice it more or less.
