What is the fix for poor touch screen response on the Triumph?

Hello,
I am convinced that something is wrong with the Triumph. I searched for "keyboard" and "response" in the thread titles but got nothing.
Basically, the screen doesn't register my touches consistently. Is this something that is fixable by a software update, or is it faulty hardware? It's almost like I type too fast for the Triumph. But when touching a link, it often doesn't register, either, and it's not localized to any particular area of the screen. Slowing down my typing seems to help, but this is making the phone in my opinion, unusable. I have no reason to believe that I got a faulty unit.
What is the fix for this problem, and sorry if I missed the answers somewhere in the forums.

No, I have not, but I have thought about it. I've heard conflicting reports about whether that helps or not. In the past, I have not noted these screen protectors to be causing the problem. Can anyone speak with authority about whether removing the screen protector solves the response issues? It's a one-way procedure, because there's no way that I'll be able to get that screen protector applied as perfectly as it was at the factory.
Thanks

I can't speak with authority, but I can speak based on personal experience. It made a HUGE difference for me. And no, I haven't had any scratches on the screen nor have I had any problems since I removed it.

I can't say but I have notices that when my available RAM falls below 50 mb that the touch becomes less responsive, that and cold fingers.

The touch screen does lag, regardless of the screen protector. Its most apparent to me when opening the app drawer; it's hard to get the screen to roll. I think it's a combination of literally cold fingers as well as a sort of metaphorical coldness of the device itself; it seems that the lag effect diminishes as the device settles into its groove after prolonged use. I notice the lag when the ROM is 'fresh.'
I am on my 2nd T and they both exhibit the quirk. LPP and the new ADW seem to help her work it out. Perplexing little devices on an intentionally-attenuated redheaded step-network, fer sure, but virtually unbrickable, and oh my black jesus do i ever love me my $25/month, contract-free ultimateness.

I've spent a lot of time trying to resolve this issue in the TG-Reloaded CM7 ROM. Updating & rewriting the bi041p touchscreen driver in the kernel. I'm finally ready to just say it's a hardware problem, maybe a grounding issue. The interrupt sometimes just doesn't trigger reliably.

Well they're are two things you can do it increase the touch screen sensitivity,the first way would be to flash ROM or a kernel that has reworked drivers that are supposed to help touchscreen sensitivity a little.The next thing you could do that I think would greatly improve touchscreen sensitivity would be to take of the factory installed screen protector as it is very thick and low quality.

A510 freezes - one bad tablet or general issue?

I got my A510 two days ago and after my initial delight with the device dissipated I got into testing it a bit. In 12 hours of testing (playing back medium res video on loop) I had two complete freezes requiring a hard reset. I was using Mobo player. This is just not acceptable for me so I'm sending it back today. Looking for a replacement tablet there's nothing that really fits the bill. The TF300 is very similar and I would go for that were it not for the silly speaker placement that gives imbalanced, mono sound when playing back video/audio.
Essentially, I want the A510 but without the freezing problems so my question is whether I just got unlucky with a bad device or if this is a problem common to this tablet (or indeed the Tegra chip in general). The device does heat up quite a bit but that in and of itself is not a major issue to me if it's not the root cause of the crashing. If it's a known problem is there any chance Acer will fix it in later batches of the tablet?
The A700 is a little outside my budget but I would pay the extra €70 if I could be sure it didn't have similar issues so if anyone has rigorously tested both models and can give any feedback as to the reliability of each I'd love to hear it.

Well, I bought an Iconia A510 and experienced the touch screen issues during the very first minutes of usage. I sent it back to Acer for assistance twice in a month. After a touch screen and a motherboard replacement still the problem hasn't been solved.
While I was waiting for the A510 to be fixed, I ordered a brand new A700 from Amazon.
I would have sold the A510 if the A700 had satisfied me.
The touch screen issues were almost absent, though it happened a few times to the screen to become unresponsive. The heat on the lower-right corner was there and present. I experienced a couple of reboots too (expecially during high demanding 3D games).
Due to the higher resolution, a few games didn't run as smooth as on the A510.
Watching the movies was a very pleasant experience. The screen was really great as well as the stereo output coming out from two separate and well positioned speakers.
While I was impressed with the Iconia A700, I resolved to return it back to Amazon because I realised that the only benefit I would have had from the new model was the screen resolution.
The A700 inherited all other major issues affecting the A510 (touch screen, heat and reboots).
It could be that I received a defective device. Still I haven't read very positive feedback on the A700.

Thanks. Looks like yet another missed opportunity then. As a matter of interest if your A501 is still misbehaving when you get it back, what do you plan to do?

Well, the tablet is in my hands already and like I said in my previous post it is still misbehaving. I am eagerly waiting for the next OTA to be released. There are reports that the touch screen issues have been resolved in which case I am going to keep it.
I will give it to my little boy otherwise.
Since he repeatedly bangs on the screen as long as it shows anything that he likes, I am pretty much sure he won't notice any lag on the touch screen responsiveness!

my a510 freezes too. totally randomly...black and white screen, or gray.
and then the only way is to force rebbot manually with poweroff.
i got my one replaced too, but still find this frezees...or simple app crashes...or lags
i opened a similar thread...but no answers. my firmware is italian 1044.00 wwgen1
@slrvboooh
what's your firmware build?

Thanks God I Finally get a No Problem Tf700!

I returned a TF700 and replace a order again on Amazon
I just got my TF700 and the first things I do is press the screen down to see if there is a clicking sound or loosen screen problem.
Thank god it doesn't have such problems
Then I turn it on and check for light bleeding. Well, there is a light bleeding spot on the left corner, but not obvious and won't be notice under normal use.
The rest of the TF700 are fine.
Now I am waiting for the case and screen flim.
I am not going to use it until the case arrive, last time I drop it from around 5~8cm height and the corner just blend and the screen pop out. I cannot believe how weak the structure is (Absolutely much weaker than the ipad!)
Hope the case could give some protection.
Waiting for JB now

Yes, +1 on the case. It's really important to have some protective covering for this device. It's so beautiful and it would be such a shame to scratch and mar it up.

Without issues, Asus's tablets are the best:good:
Sound funny but it's true.

Do you have Bluetooth earphones to test it out with? I am happy with my tablet except for the Bluetooth audio lag.

What about lags and performance ?
Mine is perfect built with no hard ware issues, but I feel there are some software issues. I want to know is it common issues or only mine.
Some lags in main screen when first time going through them it looks like it needs time to load the pages and when downloading/updating apps from the market there are some freezes in screen and sometime while browsing using chrome the device become unresponsive and the screen freeze and I have to shut it down...
The device is great, but I'm wondering about the software issues and smoothness of this CPU

same here but i think it's more noticeable because i have a nexus which is very smooth. hoping jb solves all the lagginess.

I just received my TF700T 64GB from Amazon yesterday and no issues with the screen clicking, actually it is very solid. It does have some light bleed out on the start up screen. But any other time it is not noticeable at all. As for the BT issue, that I am not sure of since I don't have a BT headset.
I did have a Freeze and Crash with loading Glowball. Once I turned it off and back on, it didn't seem to have any issues. The lags, in loading pages I have noticed this every once in awhile, which is strange. Wasn't sure if it was my Wifi network. However I have not had any lagging to the point that it locked up the page where I would need to shut down and reboot.
As for a case, that is not for me. You purchase a device like this due to performance and how thin it is. By putting a case over it, then it is thicker like some of the competition. Besides when dust particles get behind the case it will scratch the aluminum anyway if not careful. Not quite sure how one drops such a heavy device. If you have Accidental Damage insurance on it, no need to worry. File a claim and get a new one, issue fixed.

Traded my prime in at my local BestBuy for an Infinity. Clicking around the screen and the buttons were mushy. Second Infinity the buttons were still mushy and there was a poor mesh between the aluminum back and the plastic strip. THIRD Infinity SEEMS ok (cross your fingers) buttons click good, not really mushy, no clicking around the screen, all seems well!
The clicking could be because the glue they use stays tacky for a bit. I would assume that after a month or so it should cure and stop being tacky thus the clicking. Just an idea tho...

It's actually a shame that there are threads devoted to receiving a flawless prime. Not knocking the OP or anything, but it's crazy how we shell out 1/2 a G for a tablet and "hope" that it's a good one... I got fed up with the stutters, lock ups, questionable-hardware-so-lets-blame-it-on-the-software concerns... I had a tf201 and was lucky enough to be able to return it directly to Asus and get a full refund, then I turned around and got the tf700... Went through two of them. First one had mushy buttons and a clicky screen... It was a c7... Then got a replacement which was a c6. Turned out to be a better build than the c7, but the GPS didn't work independently like it should have. Then, I checked the c7 and that didn't work the way it should have either. Both needed google location services active for GPS to work! Between that and reading about the tf300 issues with JB and experiencing the sluggish response times, non responsive touch screen, icon-less home screens, app force closes, decreasing wifi reception and just about every problem under the sun (ala prime), I finally decided to return it to amazon for a refund. It seems like the infinity starts to get really slow as you use it more and more... It has potential, but I don't have the time or bank roll to wait and gamble...
I'm sure there are people who have perfectly working infinity's but I wasn't trying to hold my breath any longer just to hope that JB would correct all the issues... I'm actually eyeing the iPad, but will probably wait until October to see what apple has up its sleeve... I don't care for apple, but truthfully speaking... Their products have a LOT less issues and the developer devotion to some solid apps only available on the iPad have me steered in that direction. I mean, I can't get scrabble for the infinity or the prime (when i had it)... Really?!?!
Well, good luck to the infinity owners, I'll still follow the forums just to see how things turn out, but I think I'm done with Asus... It's really a shame, because they have so much potential...

A510/A700 Senstivity Test

Hi guys.
Before buying my A510, I used to have a SGT 10.1. I sold off my SGT 10.1 2 weeks before getting my A510, so I was never able to do side-by-side comparison between the two.
However, judging by the response in the forums at that time and by my personal usage, it was clear that the Acer tablet had some serious sensitivity issues. I couldn't confirm how bad, but it was bad enough to be noticeable by me based against my SGT 10.1.
To me, the worst thing is when putting the tablet on a hard flat surface, like a table. This is where the sensitivity, for some weird r!eason, takes a very BAD hit. I just got a Note 10.1 yesteray, and used both side by side. The Note could flawlessly take input when laid flat on a table. But not the A510.
Any idea why? Do try if your tab takes a hit when placed on a flat surface and let me know.
Thanks

I had an A510 that I returned for just that reason; sensitivity not only took a hit, it became almost useless when laid on a table. Problem was compounded by a screen protector. A700 seems much better. However the most recent update (1.029 -> 1.057) actually made things worse as far as the touch screen. For a while I flashed back to 1.029. Then I decided to update to 1.057 and root, and now I am using Acer Liquid Settings program which requires root & seems to help sensitivity. I am typing this flat on a table with only 1 or 2 missed touches for this reply, all in the 1st sentence.
Edit: There is a YouTube video that illustrates this problem in the A510 Search A510 problem on YouTube.

Indeed, I have EXACTLY the same problem as that in the video. The actionbar is TOTALLY unusable on a table. When I lift and use it in my hands, things are much better but still very much worse compared to other tablets.
Now, the thing is, from what I read, an update from Acer caused this issue. Can anybody vouch for that?
I got my tablet in mid-June, and by then it was running on the latest version. I've not gotten any new updates to fix this issue. Assuming it is a software problem, why hasn't Acer issued a hotfix? Also, this must mean ALL A510s are affected right?

screen protector?
ok, may sound a bit weird, but i experienced exactly the same "issue" on my a700. if i use the tab in bed or in the stand i got no touchscreen response. but this inresponsiveness has startet sometimes after mounting a screen protector at the tab. it just takes a while, until i recognised this behavior. travelling around the last weeks and was trying to navigate through the music library at the hotel brought the problem up first time.
since i removed the protector foil, the touchscreen response is back in all situations.
regards

There have been past threads on different devices that point to a grounding issue when this occurs. Your body is a conductor when holding the tablet so it works better. If the device is grounded properly then there isn't an issue either way. If your saying this was the result of an update then that's better then a hardware issue since it can be fixed much easier, once the company is made aware of the issue of course.

Don't hold your breath...

Yes a software issue can be fixed more easily...
IF the company decides to acknowledge the problem, act on the information and then go to the (likely considerable) expense of creating and releasing an update to address the problem. There have been many reports of this touch screen issue in the A51x & A7xx Iconias throughout the Internet especially, but not exclusively, if one is using a screen protector. Amazingly Acer claimed to address this in most recent OTA update for A700 (1.057), which was stated to address touch screen issues; it only made them worse on my A700. Go figure.

So I have the A700 and do not find any difference in touch sensitivity between the tablet laying down on a table and it being in my hands. Are you guys finding a big difference between the two?
Unfortunately it doesn't mean its perfect as I do struggle with touch sensitivity with the edges of the screen sometimes, which can be annoying as a lot off apps/browsers tend to put buttons in the corners.

Quick fix is to toggle the screen sensitivity everytime you boot up. (Change to medium then back high again, you do this every boot.)
A more permanent solution (applicable to the A510 only), is to flash NoThrills' optimized A510 rom along with the included NoThrills Kernel. This has solved my screen sensitivity issues.

Oh my God, you're so damn right! One of the first things I did when I got my tablet was putting the sensitivity to high, and I have never changed it since. Now that you mention, I put it to medium, then immediately high. Using the tablet on a flat surface is possible...my taps get registered flawlessly.
So, this means it is not something wrong with the display panel itself, but a software issue. Here's to hoping that Acer will fix it. Really weird man.
PS: Is there a code that I could tweak in the buil_prop maybe? I don't want to be flashing ROMs at the moment.

I was also wondering whether screen sensitivity could be addressed in build.prop. Anyone know?

I currently do not know of any build.prop or init.d solution. (So I guess it's more complex than I thought it would be.)
As mentioned though, I don't have the sensitivity issues anymore since using NoThrill's Optimized A510 WW ROM (The kernel was the one that fixed it I think, since I flashed Acer's stock kernel and I got my sensitivity issues back.)
So you might wanna consider flashing a new rom, or, flashing a new kernel at least.

Problems

I am going to buy this tablet very soon but i heard from some people that there are some problems with it like lines flickering over screen and creaking bezels is this true or is it already fixed?

Both of those issues are still present. Black lines are still there and bezel creaks on every one of the units I have seen.

Yes it is still present but those are actually EXTREMELY minor issues. Every electronic you buy will have something wrong with it. If its not when you buy it then probably later on. Why it is suggested to not unlock your tab for 2-3 months to make sure its working correctly.

Oh how dreadful, the case creaks... Have you ever held an sgs3 or a galaxy tab2? Sounds more like a lousy horror flick.
You're obviously no gamer, or you'd know well enough the black lines are a vsync screentearing problem, and they happen with every app not designed to handle the device's higher resolution and refresh rate. Blame the devs, not the device. (face it, no other device has this high resolution, and the one that (nexus) does has people complaining about the same bloody thing.)

Not really - vsync-related screen tearing does not cause black lines and also is only visible with movement (especially horizontal movement). This effect appears on static images.
After a lot of research, my current theory about the black lines is that for some yet unknown reason the display controller is blocked from reading the framebuffer for a short time. Since the DC needs to refresh the panel 60 times per second, it must be able to continuously stream data from the framebuffer RAM to the display.
At 1920*1200 with a pixel clock of 154 MHz, the line rate is about 74 kHz - so shutting off the DC's RAM access for only 1/74000 second would cause a full black scanline.

For what it's worth, here's my anecdotal evidence having owned an Infinity since November:
- No black lines whatsoever. But I do *rarely* get some flickering (the whole screen seems to bounce left and right) that only lasts a split second. Some apps *do* get the occasional graphics glitch, such as non-textured polygons. Overall, it's nothing I ever think about and doesn't detract me from the tablet one bit.
- Don't know what you mean by creaking bezels - all around the screen? Or just the dock connection? I don't have any creaking. The dock connection does feel "looser" than in the beginning, but it never changes position. The tablet is heavy enough that you can easily cause it to tumble backward when docked, but if left alone it never falls back. I prefer the light weight of the tablet+dock to a solution with a heavier dock.
Overall I'm very very happy with this tablet. My only gripe is the office suites aren't perfect MS Office replacements (yet? ). Other than that I've been using it LOCKED and ROOTED on stock 4.2.1 for web browsing, laptop replacement (Word/PDF viewing and editing), gaming and e-book reader without major issues.
As I said in the beginning, this is purely anecdotal since I don't know anyone else who owns this tablet. Hope it helps!
