[Q] Android touch lag - Android Q&A, Help & Troubleshooting

I've tried most high-end android phones and find they all share the same touch lag issue. When I slide my finger on the screen, the screen doesn't react until my finger has moved a few millimeters or so(which is easily noticeable). This problem does not exist on iOS or WP7 or even Windows Mobile 6.
Is the touch lag related to the android kernal or the visual machine? Is it fixed on the Galaxy Nexus? If not, is it possible that the lag will be fixed in the future. I surely hope the problem be fixed way before the day when android fades away.

Depends on the sensitivity settings of the touch screen according to the manufacturer. A lot of the phones like the HTC Raider or LG Optimus LTE don't have a delay between when you touch and when it reacts. But all current androids have a little lag in rendering the sliding animations, which is due to there being no GPU rendering present in pre 4.0 android OS's.

The delay exists on the Sensation There isn't much difference between the sansation and the Raider right?

[Q] User Interface and Screeen

Hey guys.I'm considering getting a Optimus One, but I do have some questions.
1) How responsive is the user interface (Is it smooth or does it lag)
2) How responsive is the touch screen? How does it compare to an iPhone's?
3) The touch screen is capativive right?
I have a choice between the Optimus One and the HTC Wildfire, but I don't have a clue which one to get. Any adviice would be great.
Mate... if you're wondering between those two... Just go for optimus one! I have some test units for development and I just prefer my own. Those wildfire are worse (in every way)! Lauzy resolution, not smooth, sometimes buttons just aren't rendered correctly and (for me it isn't good) the screen is too sensitive.
1) Smooth (and even smoother if you install laucher pro)
2) Very responsive
3) Capacitive, yes
And again, for your own good, do not buy a wildfire...
1) How responsive is the user interface (Is it smooth or does it lag)

I didn't noticed any problem. Always is really fast and I haven't any problem even with more application running. Only some time when I my Smart keyboard appear, I noticed small time between 1st touch and responce (about 200ms). On second and next is everything ok (maybe problem is in load of dictionary from SDcard)
2) How responsive is the touch screen? How does it compare to an iPhone's?

I had't touch screen before, but I think that it works really nice. Some time I noticed casual (I don't know it this is right word) touchs, but I thing that it's caused by me, becouse I'm not "experienced" with touchs By time is going, it works more better with me
3) The touch screen is capativive right?

Yes, it is.

I have same choice, but when I red about battery time, I chose Optimus One. HTC many times have problem keeps 1 day. With my Optimus I attacking 2 days. Also there was some notes about better readability of display on sun (but I can't confirm this).
Thanx alot people. I think I've made up my mind, I will get the optimus one.
Just one more quest, as far as I know the Optimus One does not support 3d gaming and I have made piece with that, but then I found this video on youtube, where a guy is playing Need For Speed Shift on his Optimus One.Just search for "optimus one nfs shift" on youtube (Sorry I cant post links yet). Can someone mabey confirm that it is possible as it just seems just too good to be true.Once again, thanx for the replies.
I am not sure that's correct.... I thought the OPTIMUS 1 had a dedicated GPU Adreno 200? Which supports OPEN GL.... I am pretty sure the Wildfire does not have one.

Well, Here is the deal on our phone , link @ goo.gl/2PCYC :
""Quadrant benchmark application measures the overall performance of your phone. Given that the CPU component hardly received any improvement over MSM7200 series, it is natural to conclude that other areas received significant improvements. One area in particular, is the GPU. MSM7227 features a dedicated GPU called, Adreno 200. This is the SAME GPU that is found in the first generation Snapdragon processors!
.......
And then there's the screen resolution. Typical Snapdragon phones use 800x480 screen resolution, while most of the MSM7227 phones use 320x480. That's less than half the amount of pixels MSM7227 has to process through. The result? Surprisingly snappy performance out of "lowly" 528MHz/600MHz processor!""
& i even tried ExZeus (link: goo.gl/pkA6D ) which run well too.

Thanx alot for all the replies guys. I've just signed my contract and decided on the Optimus One.Will receive it later this week. Be good and thanx again
hii buddy m also plannin to buy lg optimus one!!
did u buy it?howz the response?pls share ur feelin

[Q] Galaxy S2 ICS ability

Hi,
Anyone out there with experience of Android updates to older phones and how well they handled it.
I ask because I want to know about the Galaxy S2 and how well we expect Android 4.0 (ICS) to be implemented.
Of course, it will come out at some point, but my primary concerns are whether it will add to the battery power needed burden to make things run smoothly as it will retrofit the S2 hardware.
I also want to know how easy it is likely to be to replace the on screen buttons with the S2 hardware buttons, as this will be a waste of screen space on the S2 if it is still to pop up there above the hardware buttons.
Any help and other thoughts on the matter will be much appreciated.

To say anything on how it will be implemented on the S2 would be pure conjecture. No one knows yet.
Its still in the middle of being ported/hacked over to our device, with no official Samsung ICS Roms released/leaked yet.
Regarding the 'on screen button' query, it would seem that ICS would detect capacitative buttons, and thus hide the on-screen buttons.
Hi,
First of all i wouldnt class a Galaxy S2 as an older phone, samsung have made a point of holding back on the Galaxy Nexus hardware so it doesnt outdo there own flagship model.
Yesterday, I compared a Galaxy Nexus to my Galaxy S2 running the ICS alpha and was slightly disappointed that the Galaxy Nexus screen didnt look any different to my GS2 both in screen real estate and screen clarity.
I doubt very much ICS will reduce battery life as the hardware acceleration should help matters as there will be less reliance on the phone CPU to draw things the GPU can draw easily.
The onscreen buttons can be easily disabled and dont offer anything that the GS2 hardware buttons dont. If anything the GS2 has the advantage of a menu button which you dont get on the Nexus and until the majority of apps put a software menu button on their apps it's going to cause issues, i thought that the software buttons would be more intellegent and add a menu button for legacy apps but they just seem to stay the same buttons all the time. I know paul o'brian has done a custom mod for this so hopefully google with do the same.
I personnally am happy with my GS2 hardware, the issue for me is software and whether i can wait for 4.0 either official or unofficial.

There actually IS a "virtual menu button" for those apps who use the menu.
But it's rather small and easy to miss.
It's on the far right, looks like three dots above each other, I could use all "old" apps I tried so far with it and effectively not using the "real" buttons at all.
I hope if ROM cooks tend to remove the on-screen buttons, they keep an option to re-enable them, 'cause I really like them
(and they are NOT showing up in the SDK emulator, so it does seem to have some kind of detection.)
ICS does not show the Virtual Buttons on devices with HW Keys.
Thats an absolute, 100% given, please stop discussing about it.
The Galaxy S II has a better GPU and a CPU I'd call Equal with the one of the Galaxy Nexus, also the screen has a way lower resolution, so it might even run smoother than on the Galaxy Nexus,
But what about future apps.....if they are built to a standard 720p resolution, then will the Samsung galaxy S2 suffer then compared to the Nexus which has similar spec - ie do you think we will get new apps that will run better on a 720p screen which looks likely to be more standard in all future high spec phones ?
In my opinion, Galaxy S2 will perform much better on ICS than Gingerbread, considering ICS will actually utilize DUAL-CORE efficiently, rather than just burning battery on two-cores just to work one-core...
It's like XP before & after SP2

You are trying to find a future-proof a device. Well - it ain't gonna work. Technology moves at a quick pace. At most - I can say GSII may work super well with all apps (and games) until a point when it has become the standard for all screen resolutions to be 720p or 1080p or 9040p. This may be in 2 or 3 years.
Besides, an app developer would make their app compatible with all devices UNLESS they intended it to run purely on a certain resolution.
Nexus phone isn't better than the GSII by the way. It just has ICS on it. =/
Thanks for all of you inputs guys.
Sounds like the GS2 will work as well with ICS if not better.
It also comes across that although the screen size if the GS2 is smaller than the GNex, it is more or less cancelled out seeing as the GNex has to use some screen for the virtual buttons at the bottom, wheras the GS2 will not have to use any screen on this.......therefore negating the screen real-estate difference.......right ?
Then it only comes down to resolution between the two.
For a much lower resolution, the GS2 still looks amazing to the eye, which makes me wonder what the real worls advantages will be of the higher resolution screen on the GNex.
Could it be the web page layout or looks when they load up ?
Could it be noticed when playing media ?
I am not sure anymore.
Ideally the resolution advantage comes into play during
1. Browsing, especially while reading small text as very small letters can be drawn accurately.
2. Pictures will be more clearer, especially some wallpapers do ask for more resolution.
3. Video playback
Altogether everything will appear more smooth and clear. So a welcome thing this resolution is. But nexus has pentile display and there are chances this might offset the resolution advantage mainly during text diaplays
Sent from my GT-I9100 using XDA App
I agree with the last comment to an extent. But we are talking about a phone screen with hundreds of pixels already.
To the normal user in the real world, do you still think that applies ? Ie the text might be a little clearer, but is it not darn clear already on the lower GS2 resolution ?
And wallpapers - even if it was origianlly a 720p picture and the GS2 resizes it, would the average guy out there be able to distingush ?

Here http://t.co/RzNWJWcQ , Have a look how stock ICS looks and works on GSII. And all this is done without any driver source code. Imagine how quick it would be when samsung does ICS with proper drivers.
At least Samsung confirmed they will release ICS to S2. When? That's a different story... Probably late next year.

problem with new touch screen..

dear everyone.
I accidentally broken the touch screen of my tablet. after a long time i found jetstream touch panel and ordered from internet store.
but now after changing touch panel my touch panel not working anywhere.
my tablet is at&t htc jetstream.
Is there any difference between the at&t jetstream and other version?

After hearing about the some of the issues that users of Hive have gone through I began to suspect that there are two (or more) different editions of the HTC Jetstream. Later when I was working on the kernel I discovered that there are two kernels -- that differ very slightly.
The short answer is that I have noticed differences, but I cannot say for sure if it goes beyond just software differences.

3D touch Xposed module

there should be a 3D touch tweak just like in Iphone JB tweak...
What do you think???

I don't think that happens.
Because 3D touch is related to hardware specifications.

it's not related to hardware the older Iphone's are having them by Jailbreak tweaks!!!
Does it actually work properly as opposed to being a software work-around for a hardware feature?

Yes it work properly.. Just 3-4 months back in my iPhone 5s I was having 3d touch feature via JB tweaks...
http://forum.xda-developers.com/xposed/read-posting-module-specific-questions-t2752716
This is off-topic but I did a little searching about the older iphone's 3D touch thing and I found this:
http://www.idownloadblog.com/2015/10/14/forcy-3d-touch-older-ios-9-devices/
Obviously, Forcy isn’t a 1:1 emulation of true 3D Touch, as that requires special hardware beneath the screen for pressure sensitivity. Instead, Forcy relies on a simple swipe gesture to invoke its shortcut menus. It’s very similar to the look of 3D Touch, down to the animations, but it’s still not true 3D Touch, and it doesn’t feature the haptic feedback that makes the feature so impressionable.

So in other words, it's exactly as I described
So we can develop a module like forcy for Android with 3d touch animations and shortcuts..

Multi-Touch issues

Hi there, recently i bought lg v30 us998 version, android pie with august patch. When i play pubg mobile, moving and aiming is mission impossible, screen goes unresponsive or my tap an hold swipe register as tap only... I gota feel that screen is too sensitive touching, pubg is unplayable. Any fixes through software or i don't know which way - should appreciate...
here's the problem: https://youtu.be/wgYN5GwIgIc
As far as i can see it's some kind of bug from Google, they got fixed for pixel 2 line, but lg v30 not... Very disappointed, any help would be grateful...
nobody?

i know a lot of people play PUBG on v30 and none have state it unplayable.
Mine however have randomly not registered touch when playing cytus 2 , mostly when one finger swipe and the other is hold.
hmm, sadly i have big problems like yours and even worse sometimes while multi touching operations applied playing pubg... i am wondering did they apply that bug fix from oreo in this pie version or not, because they are so lazy about doing proper updates...
You fix this?
