Sluggish Acer N311

Hello.
I'm dealing with this PDA that's from a friend. He told me that it's very slow (it had WM5). I update with some homemade ROMs to see what happens and the result has been really annoying:
Operations are sluggish. Even the screen aligning process is horribly sluggish. Everything is slow as hell. The screen seems to miss some taps, too.
What's the problem? Somebody with this problem?
EDIT: I have seen that the touch screen is failing! The taps are hold when the stylus is not on the screen. Could it be a failing touch screen?

Well, later to have checked and tested intensively I've come to the conclusion that this lack of responsiveness is produced due to a hardware error. The touch screen is failing and the CPU processes a large a mount of taps without actually touching it, so it's too busy to process any other task properly.
I hope this help to anyone having the same problem.
Thank

Issue with touch screen ?
Concerning your sluggish PDA, is there a plastic film to protect the screen ?
Some plastic films may cause very weird behaviours as the screen could be fooled and act as if some point on it would be touched. It's all the more true when the film is in contact with both the screen and its frame, due to bad alignment when sticking it.
I had a similar issue with a Tomtom One (1st issue) and was about to send the device back to warranty... everything was solved when removing the protective film !
It's rather obvious with first generation films that were really thicker than new ones.
Hope I was of help...

if you cant fix it and are going to get rid of it i will take it off you. mines motherboard is scrambled, but the screen is fine.
thats if your getting rid of it.

Distortion on Fuze LCD screen

I just noticed today a rectangular area on my lcd screen where it looks like oil on water. It's basically a rectangle w/ a half inch border of the "Normal" screen. I can see it from any angle as well as when the phone is turned off. The phone and the touch screen both appear to be working fine. The distortion will react to pressure on the distored part of the screen as well. I'm thinking some moisture got in my phone some how (although I can't for the life of me think when I could've gotten moisture in there). Is there an easy way to fix this or should I call up ATT support to see about sending it in to have them fix it? What's the general next step? I'll post a pic when I get home to my camera. I've had the phone since the first of the year and am currently using EnergyROM 2.0.
Thanks a ton,
Patrick

I haven't seen anything like this before but if it it was you say its probably moisture inside or even oil. Wait a little and see if it clears up, failing that give AT&T a call.

Holy Crap
Dude i have the same problem with mine sometimes, and i thought i was the only one!!
Its almost like the LCD screen is getting some burn-in. Even on a black screen you can see the shadow of an image, using touch flow 3d/2d its about half of the slider bar on the bottom of the screen. Did you also notice that the screen is flickering VERY slightly in the same area, but not on the rest of the screen? You have to try REALLY hard to see it. Almost like when you use a camcorder to see a CRT monitor's refresh rate. I had a feeling from the beginning that it was moisture causing this, because i do have the bad habit of taking my phone in the bathroom when I shower. My LID has turned pink because of the steam.
What makes me think it could be screen burn-in, is that I always keep my backlight as bright as possible, and once i see this start happening, i can turn my phone off for a few minutes, turn it back on and it works just fine with no image shadow.
I actually have been thinking about using my insurance to get a new phone because of this, and making sure i don't shower with the new one.

It's a known issue of the phone. I was able to get mine replaced, but I had it less than 30 days. You should be able to manage to get them to replace it if you make them look up known issues with the phone.

Sorry for the inactivity, I've been spending my days pulling Cat 5e in attics and haven't had much computer time at work / energy at home - I'm going to get in touch w/ ATT sometime this week and see about arranging a replacement, I'll post my results.

i have the same problem. near the corners i see very slight flickering as if the refreshrate can't handle the tf3d.
it most likely because of the themes. when using all of those non-original themes, it' shaving to load all the images, causing it to have very very slight lag. maybe?
it's rediculous, with the price of this phone, you'd expect higher technology for the screen.

Your digitizer is touching the LCD because too much pressure has been applied to it, probably in your pocket.
What you are seeing are Newton's rings http://en.wikipedia.org/wiki/Newton%27s_rings

I think we're talking about two different problems here.
First, you have the rectangular area like the topic starter described and may indeed be what bubble said. However, they are not rings... its a true square (at least for me).
Second, you have the flickering issue. I have this myself sometime at the position of the menu bar. Opera seems to be the only app that triggers this for me though - then i get flickering Opera 'burn in' like effect. This will eventually disappear again after keeping the phone off for a few hours, then on with the screen off. This effect does survive soft-reset and such.

Newton's rings is the name of the observed optical phenomenon. It has nothing to do with it's shape.
I know that in this case it appears on a square section of the screen (I face the same issue and I already ordered a replacement screen).

Is there a solution to the flickering and screen burn problem? I didn't notice it until I had loaded a 6.5 rom and was using the light colored R&R theme. I could then see flickering in the bottom portion of the screen. Then I notice the screen burn of both soft keys.
It went away overnight with the phone off, but came back by the end of the day. It's really upsetting as I love this phone, but hate having something that isn't working right. Any suggestions?

I've had the same issue a couple of times although it wasn't nearly the entire screen. It was just a small blob in the very center of the screen. It happened because it was in my pocket. When it occurred initially it was summer (30-40 degrees celcius here in Perth) and would fix itself after about 5 minutes of being in my hot car (temperature hot, not awesome hot =D ). However (more recently - it's colder now) it stayed for half a day or so and only fixed itself after I sat it in front of the cars heating vents with the heater on for about 10 minutes (not too hot). I'm wondering if the digitiser separates from the LCD when heat is applied. It makes sense to me but I'm not sure I'd recommend anyone trying my solution ... especially if you've got the big square issue.

You also have to be aware that this phenomenon is only visible under artificial light.
That's why some people report it to disappear/reappear.

True ... but when the "phenomenon" disappears (i.e. as the lcd seperates from digitiser) it makes a clicking noise and the screen behind the blob flickers (like when you push on a normal LCD with your finger) indicating that the pressure of the digitiser pulling the screen upwards has been released. Once this has happened the blob has gone. It's not visible under ANY light.
If it happens again ... I'll get some footage.

I found another thread regarding the "Oil Spot" that comes and goes on the LCD that I'm experiencing if others are interested:

Oops - double post

Hi guys, I have the solution for you! I see burn-ins on my screen and I was able to get rid of them with a simple video that switches fast the main colors (Red Green Blue). Here is the link to the video:
http://www.youtube.com/watch?v=liMySLZkF5o
I have the video pulled from youtube as mp4, and 5 minutes of playing on full screen, the display got back to normal, clear and without any burn-ins.
If you need the mp4 vid, let me know so I can send it over (email)

Problem after touchscreen replacement (original one)

Please help me with this touch screen problem:
In my HTC sensation 4G touchscreen has been replaced (together with display) and as a result I've noticed that device no longer registers fast swipes. No lag or other problems, just when you move finger fast - touchscreen fails to register it. In multitouch tests circle disappears during fast movements and in games like fruit ninja there is no line after the finger. Guys who helped me tried several digitizers they had in stock and all of them had this same problem.
My original digitizer and these ones are probably different models because mine was T-mobile and these have HTC written in the middle.
So I wanted to ask did somebody stumble upon this issue and is there a solution?
Or is it possible that all new ones they've tried are bad?

i have similar issue. my screen doesn't register any touch on the left half, unless i touch the right half a few times first...:/ my digitizer got changed as well. but after that all is fine...only after i turn off the screen, then on again.....it's a little annoying, but not making my device useless at least.
as for to what's the cause, possibly each phone needs a special digitzer...as for the solution, i tried many, nothing worked...

I read of someone with a similar problem, they took screen apart again and found the wire was slightly pinched, they said they carefully put wires back in place and paid extra Attention to the wires and problem was solved. Now, I personally have not tried it but I did read this fix. Maybe it might help, worth a try? Hope this helps!

I'm on the same boat. Dropped it and cracked the screen. So I bought a replacement screen and replaced it myself. Its the one with just the HTC in the middle. (I'm T-mobile) Well now, like yours, it sucks at registering touch accurately. I have to press solidly on the screen to swipe screens or to open apps. Texting sucks because i have to press on each letter good or else it picks the wrong letter. I've searched for a solution as many have had this issue but seems like they just returned it for a new one. I cant since i replaced the screen and voided my warranty. I have taken it apart twice and carefully reassembled it making sure everything is good and snug and in the right place.....Still no love....Sucks! If anyone can help, it would be much appreciated as i have hit a dead end with this issue. Thanks.

this is quite different problem. Sensitivity of my display is OK unless you move fast. In your case it seems to be the problem of this exact screen. Try downloading SGS Touchscreen Booster from Play Store and play with settings.

[Q] New joinee-About HTC one X issues

Dear members,
I would like to know the truth behind the issues faced by the HTC one X, which I read in many websites across the internet(and few here)
I was decided to get one for me untill last week, but the issues what I read for one X confused me.The issues that I came across was;
over heating(guess its obvious for smart phones)
Wi-fi issues(death grip issue)
screen/display flickering,
yellow spots on display,
Frequent black screens,
Restart troubles,
Music player issues(when music player stops when gallery is used)
Taiwan made phone's facing issues over Chineese made ones.
Kindly address these issues ASAP, as I had already made up my mind to go for HOX, so that I can buy one with relaxed mind...
I cant think of any other smartphones as of now.
Thanks in advance

I second this post and would really like to know how current owners are experiencing these issues.

Mine is a Rogers HTC One X.
Got it about 3 weeks ago. Just sent it in for repair, just outside the 14 day exchange range
overheating wise, yes, it can get a bit warm at use but same for any small tightly packed smartphone. I didn't have any wifi issues or any issues you had stated.
The problem with mine was holding the phone vertically. About half way down, there was a 1cm horizontal strip that did not react to touch. Just where the ok and cancel options pop up on some games/apps. You would need to rotate the screen so you could "tap" those buttons and get a reaction.
I turned on the developer mode and the mouse tracking/button press options and you can trace your finger down the screen and you can see where it stops then continues with a 1cm or so gap between where it wasn't responsive. This gap was the entire width of the screen not just a spot or two in that 1cm zone.
The phone was never dropped, bent, sat on etc. Mint screen and case, no case or touchscreen protection. This issue occurred quite suddenly about 16 days in, only noticed it when some games didn't let me exit when hitting the cancel options. Originally thought the game or the app was at issue. Then realized it was the touch screen. Did a full reset a few times, same problems. Now patiently awaiting for my phone back. Rogers phone/loaner suck as well, gave me a Nokia C3 POS as a loaner. Using my old motorola milestone instead.

Strange problem with touchscreen

Hello, guys.
Recently, I dropped my M2 on the street, resulting in cracked touchscreen and lcd. Replaced both the touch and the lcd, everything seemed normal until I noticed that the middle part of the touch (a line going from the left to the right, around 1cm height) doesn't work, it just doesn't respond. Later, I got another new touchscreen and same story - same part of the screen doesn't work.
Maybe we have some kind of defect touch screens here in Bulgarian stores? Though I bought the two touches from two seperate stores. Or it's possible that it's something with the lcd? Even though it works normally, no strange behavior, no black spots, scratches or anything. Or could it be a software problem? Using Android 5.0.
Thanks in advance.

More likely to be motherboard problem if it's the same with 2 different screens being installed

Thanks for your answer.
One thing I forgot to mention - when testing the screen in Sony's Sketch app or in the service menu, if I run my finger from the top to the bottom, or the opposite way quickly, sometimes, the lines my finger makes don't get cut, i.e. it's like the screen is functioning properly, with no dead spots. What does this mean?

According to Sony support, it could be a compatibility issue between the phone/touchscreen/LCD, what do you think?
