Touchscreen "lag"? - TouchPad Q&A, Help & Troubleshooting

I recently played a game simultaneously with my cousin (to see who was the better gamer of course) on my touchpad while he started the level the exact same time on his ipad. Everything was great but then when I saw him navigating through things, it seemed much more responsive. Like as he swiped (not just on his game screen but on other things like web browsers) the screen would be just as fast. Scrolling on a browser, his finger and the movement of the screen seemed 1:1 while on the touchpad there was a noticeable lag or rubber band like effect where I would move my finger quickly and then the screen would try to keep up.
Is there any way to make my screen as responsive or is this just one of the draw backs to having android on a non android device. I found that the responsiveness is there when I am on WebOS when I tried to test out to see what was so "off"

Upgrade to TD2

I am currently using Touch Cruise. Would it be a serious upgrade to TD2? I am very much concerned about the lack of D-pad. Even with the D-pad the use of cruise is difficult. Is the screen improved?
From some reviews I read that the screen is so large and finger friendly that it negates the use of a D-Pad.
You should go for it. I upgraded from a Touch Cruise and the D2 is a far superior phone. It is far more responsive than the laggy Cruise and the screen is very high definition - almost excessively. You can read web pages even when zoomed out if your eyes are good enough.
I still reach for the dpad sometimes out of habit but I don't really miss it. Everything is do-able without, you just need to get used to it.
The D2 didn't feel much smaller than the cruise when I first upgraded but now when I look at my old cruise it looks fat and bloated and the screen pixels looks very blocky.
I do miss the rubbery feel though of the cruise since the D2 is very slippery.
If you use programmable buttons much you will be disappointed with the D2's single button compared to about 5 on the cruise. Although there are free solutions to this available.
Honestly, there's no comparison! The UI is instantaneous with everything you do. Press a number on the dial pad and it instantly registers. Press call end and the call is GONE! No waiting 2-3 seconds anymore. When you slide your finger in the photo album to swipe to the next picture the photo moves WITH your finger. With the TC you made the swipe and then waited for the next picture to appear.
These are just the benefits I can think of now.
I'm coming from a cruise too, and just loving my D2! The UI is indeed perfect. I was affraid of the accessability of some functions, when not having a D-pad, but it's just no problem in everyday use.
All daily windows menus have been replaced by larger ones, easily clickable with your finger. That includes the menus that are used in third-party programs. I was affraid about having to do a lot of actions to block the phone, when putting it in my pocket. But actually you just press and hold the end-button to block the device very quickly. There are big improvements like for instance the great TF3D, but also small ones. For instance, the D2 displays a small bluetooth icon in the taskbar, when BT is on. It even shows a different icon when the device is connected to a headset or carkit. On my cruise I always wondered about BT-status. The start menu is replaced by a bigger icon one. That one is adjustable, you can place 24 of your favorite apps there, 15 off them fit in the screen directly, for more you have to scroll. The other apps are accessable when you hit 'all'. Then the whole start menu appears, but again: larger. The TF3D home screen shows the next 3 appointments, whereas TF2D versions for the cruise always showed only 1. The TF3D calendar doesn't fit my needs though, so I'm still looking for a replacement.
On my cruise I was using a tiny program called taskswitch, which I assigned to a hardware button, to switch between applications. I use that when driving. I'll typically have at least two apps open (navigation software and Opera for live traffic information) and want to switch between them easily while keeping my attention on the road. The lack of buttons prevents that solution now, but there is a better one: AE button plus. I assigned the built-in task manager to the hardware back button and that works great! Then I assigned the function "OK/enter" to the same button, but when pressing and holding it. Now it all works fantastically.
On my cruise I have tried several ROM's. No one was perfect at all. Opera would crash often, the Youtube apps I tried would be slow and crash often. I was using the stylus all day. The Topaz isn't just better IMO, it's a whole new era.
Just one addition: a downside is the poorer radio reception. Radio reception for GSM and wifi is worse than the cruise. I'm hoping it will improve at some time with a radio ROM update. It's not bad, but it's not as good as the cruise.

Is this normal?!

Hey everybody. I've been using my Xperia for about 2 months now. However, while messing around with it the other day, I realized that it's kind of shaky. For example, if i "press" against the silver finish all the way to the right of the screen, the top part of the phone shakes a little (like it moves kind of inward). Also, when I press the bottom right soft key, the same thing happens. It shakes a little, and it's not too big of a deal but it's annoying.
Another thing is that the keyboard also slides out very easily. Like way too easily. While using the touchflo 3d with one finger (sliding to the right), for instance, unless my finger is completely dry and moving on the screen very smoothly, the screen moves to the right slightly (the way the keyboard opens).
Also, when the keyboard is out, if i "press" towards the top part of the screen, it also shakes. It feels kind of loose.
I just wanted to know, is this normal? If not, what should I do, as I bought this phone from ebay.
Other than this problem, I love my Xperia. It's very functional and like a mini PC. If it wasn't for this place, though, I think I would have probably been VERY, VERY dissatisfied with my Xperia (with the stock rom).
Thanks in advance. Any help would be appreciated.
Edit: My phone is a silver, Xperia X1i model.
I don't think that's normal. Do you tend to slide out your keyboard a lot? Have you noticed any cracks near the stylus btw?
Holy-!
How much force are you using on the screen?! My slider is exceedingly solid. Absolutely no give, and even if I use TF3D it doesn't move.

I think that's out of normal
My Black X1 has about 1mm play, on the left side. On the right side it is less, but it can be felt, exactly as you mention.
As for opening, I have no problem with that, it gives just reasonable resistance.
i try to peat as least pressure as possible while using tf3d. i also dont slide out my keyboard THAT much. and no, no cracks near stylues.
apparently, this is not normal. any advice?
redo the screen calibration, now applying as LITTLE force as you can to get the press registered, and try again. Xperia has some sort of vario force meter on the touchscreen - the more force you use during calibration, the more force you need during normal usage.
another issue i have with my phone (not hardware related) is the fact that when i use high quality on my youtube app, watching the video is sooooooo laggy. is there any fix for this
It's a limitation of the current app, most likely it's incapable of taking advantage of the native hardware decoding the MSM7200/7201/7200A/whatever chipset offers.

Screen issues

Screen looks great. But I'm having two issues.
First, the screen feels kinda rough dragging my finger across. By comparison my Galaxy S phone and iPad are very smooth and glide with no resistance.
Is this normal, can it be improved?
Second, the screen seems unresponsive at times. I'll have to tap more than one to get it to recognize an action. Maybe it's just being slow.
Also the calibration seems to be a bit off. I often seem to be clicking items below what I tapped on. Not sure it's completely user error since I don't seem to be having this much trouble with my 4 inch Android phone.
PS. The phone is rooted with AutoNooter and using LauncherPro and Dolphin browser.

My screen is very smooth, and a little bit tacky... I'd prefer a less tacky, smoother feel, but it's okay.
Unresponsive I've not noticed really, but the calibration on the edges and/or corners is funky.. Like hitting the Search button in the market is hit and miss, otherwise other places I personally haven't seen any issues.
There's a thread on here / directions on nookdevs for how to recalibrate the screen. A lot of people have been reporting issues with the calibration on the edge of the screen. It doesn't bother me too much, so I haven't tried, but results are apparently quite good.
http://www.nookdevs.com/Recalibrate_the_NookColor_touch_screen
I've recalibrated the screen a few times. Even did the suggestion with placing the Nook face down for extreme sensitivity.
I still seem to be having the same problem where the touch is very unresponsive. It's most noticable browsing the web, I'll have to tap links multiple times before the browser does anything.
I'm wondering if I have a bad Nook or is this just how it is?
It could be the default browser. I had problems with unresponsive tapping as well but after switching to Dolphin Browser HD I havent really noticed them at all. However, it does seems like only certain apps or portions of them have problems with touch response...I can think of 2 off the top of my head..
1) The search icon in the Android Market. I have to really tap it hard or multiple times for it to open the search ability. Everything else in the market is a light, smooth, responsive tap, except the search ability.
2) ADW's settings menu, specifically the back button. Have to really hit it hard to work yet everything else works perfectly fine.
Maybe it's just me but I swear its only certain things which respond poorly to taps.
In regards to the screen being tacky, goto B&N and buy the Anti-Glare protective screen film. Make sure its the anti-glare one and not the regular screen protector. Not only will your fingers slide perfectly, but it also avoids all the annoying fingerprints the default glass seems to collect. Worth every penny. (You get 2 of them for 15 bucks)
I find that I have better luck ith a light touch & avoid a "tap". It took a bit of practice to know what part of my finger was actually making contact with the screen first & the reason for the perception that the screen was out of calibration.
I do have a problem with the center right area of the screen when playing crossword. Sometimes it is very hard to click on the rufgt side boxes. Interestingly, the same area of the screen is responsive in other apps.
Cheers,

I purchased the matte screen protector from them and it alleviated the tacky feel of the screen. Also resist oils and smudges so its a must have in my opinion.

I have the same problem at the very top edges of the screen. Pressing search in marketplace or a new tab in dolphin is really annoying. Requires many taps to work. Rest of screen seems to work fine. I did notice that the 2.2 Froyo was way worse for screen sensitivity. Maybe they can fix somehow with a firmware patch or something.
I have the same problem. Will try recalibrating later.

I don't think the market search button issue is a screen calibration issue. I initially thought there was an issue with the sensitivity/calibration in the top corner of the screen, but I have the same problem with market search when I am in portrait or landscape. Touching items in the same area of the screen in other apps is fine.
My screen is definitely more responsive after doing the commands.
I made sure to clean it completely with a microfiber cloth before running the commands.
As for the market search issue, it seems to have improved the sensitivity. In fact, to me it now feels as if I am getting the button push through, but it just takes time for the app to register it and take action (lag) and thus we think the button push did not go through and push it again...

A lot of the discussion on this thread is for locale based calibration, but I had the issue where if you hold still on a drag and drop, before dropping the thing you are holding is jittery, as thugh your finger was being jittery. This calibration fixed that problem.
Under the thought that this might happen again, would be nice if there was a way to run the command locally on the system without having to connect to adb to recalibrate.
Any ideas on how that could be done? I was thinking maybe scripted terminal commands?

Touchscreen issues

Stock N7 16GB
I have always thought the touchscreen on my N7 was a bit jittery, but now I have come to realize the problem is far worse than I originally thought. For example:
Load a webpage
Place a finger on center of screen
Rest palm or other finger on left edge of screen
Display starts moving/pinch scaling like crazy, even if I remove any touch from left side of screen and keep only 1 finger on center screen.
Almost all the time the touch on my N7 jitters/moves around a bit which causes issues with swiping. If I place 1 finger in the middle of a web page, it moves around slightly even if my finger isn't moving.
I think for these reasons I will be returning this tablet.

I'm having issues with the screen too. For me, it seems worst when it boots up. my example was playing Angry Birds Space - I can't control it, then suddenly it releases and (if a bird with an action) performs the action. any known fixes?
i had same problem think i found a fix
I had same problems with my nexus 7 but it started after i installed dead triger i also noticed tablet dosint come with stock file manager so i installed the same game on my asus tf300 and noticed same issues on my nexus i did a factory reset and cant make screen get any dead spots hope this helps you out
I had that once the other day. I had to reboot it was so bad. Almost felt like the tablet was laggy. Hasn't happened again though.
I do have Dead Trigger installed as well, but I haven't played it in a long time.

Pokemon Go issue - finger tracking lags when dragging pokeball

Hi all,
The LG G4 runs Pokemon Go rather well for the most part, except when you try to throw a ball - the game won't track your finger position very well.
There is a noticeable delay in dragging the pokeball, as to where the game thinks your finger is, compared to where it actually is. You can see this when you perhaps twirl for a curveball throw, or generally move your finger around quickly while holding down a ball to throw it. You'll see a gap develop between your finger position and the ball lagging behind, as if the ball were attached to your finger by a rubber band.
Anyone know any solutions to improve the finger tracking responsiveness when throwing pokeballs?
This issue doesn't happen on the two other devices I've tried, where the ball is very responsive and stays under your finger at all times/speeds of finger movement. Also, this issue can make it impossible to throw the ball very far, because the increased finger speed needed to make the long throw is just ignored by the lagging rubber-band effect that thinks you are making a normal speed/distance throw. This can prevent you from catching certain pokemon like Rapidash, that are positioned very far away.
I have the same problem on my G4.
I've had some success with cooling down the phone, so I wonder if the problem gets worse when the phone is hot, as if the phone throttles the processor used for finger-tracking? The graphics look fine and don't slow down, just how it tracks the finger position and updates the position of the ball by lagging behind if you move (the ball will center on your finger position correctly if you stop or move slowly, it's just that weird rubber band effect).
I've waved my phone like a fan, holding from the bottom and fanning with the top end. People ask "does your phone work as a good fan to keep you cool" and I have to explain that I'm cooling off the phone.
But I'm not even sure if the cooling works all the time, it might just be placebo effect and not actually changing anything.
