Hey guys,
So I just bought a 2month used Infuse 4G originally locked to AT&T.
I've been noticing some issues and will try to explain it as clear as I can. Supposedly the person I bought it from said it was an OS issue...Hope you all can shed some light!
So pretend you're using your lovely android Infuse 4G and you're texting. All of a sudden you find yourself at the home screen, interrupted from your messaging. A couple of "huh's?" and "...wtf"'s you resume re-typing your text message.
Later you're on the highway driving to a new joint. The GPS signal has finally locked and you're cruising. All of a sudden, your GPS asks you if you want to end navigation. You look at your phone as if its a zombie and you quickly tap the 'cancel' option. Moments later, you notice the phone is back at the home screen and Google maps navigation is running in the background. You bring it back up. A few minutes later, the menus at the bottom come up. You tap the screen to make it go away and keep driving. This happens many more times while you drive even though you've already taken off the phone case.
So it seems like a ghost is touching the capacitive buttons. Not just one of those, ALL of them (Menus, home, search, back) while using the phone. It's not very frequent, but its enough to be aggravating.
Please advise, thanks!
Is there a case or screen protector on the phone? if so try removing and see if the problem persists

No offense but maybe when you hold your phone in landscape mode your palm touches them. Happens to me all the time.

Most likley a kernel issue.Go to your about section and check your kernel and rom version....if your already on a custom rom/kernel, then you might have to Odin back to stock.

It's not an O/S issue .... well, it may be on YOUR device but not a general issue. If you do an Odin full restore to stock and still have the problem you now know why the guy sold it after 2 months.

None taken! I've actually left the phone w.o a case on a table. Its pretty scary to see your phone randomly show the menu from the home screen as if you pressed the button and then close that menu itself as if you were to press the back button...

Not sure what an Odin full restore is, but i'll look into it and give it a shot. Not surprisingly, my Infuse 4G is also among the few that have a GPS signal issue. The phone locks after 30 mins if Im lucky...
I didn't pay $434 for a phone that doesnt work properly/involves tweaking just to make simple features work...*sigh*

What's up xda forums.had a couple of concerns with my phone. my nexus s stock running 2.3.2 rooted and unlocked. Here are some of my issues so far
While driving and on the phone, sometimes the call drops after making a nasty sound and stays stuck on the hanging up screen and I can't make or receive a call till I reboot.
When turning the phone off sometimes and turning back on, the screen hangs for a while and 4 seconds later ill feel the phone vibrate 2-3 times and go back to normal in which its not lagging.
When opening my gallery the phone takes about 5 seconds to show me my thumbnails of my photos.it does this every time. Also when I take pictures it takes about 10 seconds to see the photo I took. When talking on the phone I drop alot of.calls or I hear the person sound like a chipmunk lol.
Is my phone messed up? Is the stock rom messed up? I flashed a stock image thru clockwork after I tried a alpha cm7build. Was it corrupted or is my phone a pos. My nexus one never gave me this many problems.
Any help would be great

Well, yeah, most of your problems have been mentioned by someone here at one point or another. Some of them have workarounds, some are waiting for fixes from Google.
I think if you try a few searches with the search button in this and the General section you'll find already lengthy discussions on most of those issues.
These problems started after you flashed back to stock?
Try clearing caches and reflash I guess.

Maybe even a fastboot oem unlock again to force a TOTAL WIPE of the phone. Be careful, sdcard contents are wiped too.

The only major issue I've had only happened once, and it happened for the first time yesterday: Without me touching the back button it started flashing and going back through the app I was in at great speed. It was rather frustrating but its only ever happened the one time.
What some people forget is that the Nexus One also had a lot of problems apon release,
All was ironed out by google

Im gonna try this right now. thanks for your help
I was able to make one of the problems repeat.. seems cause of the case i have everytime i hit the power button my thumb seems to hold down the volume rocker right in the middle. i then unlock the phone while its still tying to catch up from something.. cause 4 seconds later it will vibrate 2-3 times and the phone is back to reg speed.. there something wrong with my rom or can ya make this happen too?
Yup I get most of these issues too, it really spoils the experience. Next time I'm not gonna get a google phone straight upon release, it's really not worth the hassle. Also does anyone have problems with the wifi? Mine is horribly weak its a joke, struggles with wifi from my bedroom which my laptop and old Iphone 2g handled fine

Okay for a good month and a half I have been having an odd problem. Sometimes randomly my phone will start glitching and viberating randomly like I'm pressing the soft buttons below the sreen and sometimes that menu comes up like I pressed the menu button. Not the launcher. Ans also I can be in gallery and select a photo and it will viberate like I hit the back button and it will go back and I have to select it a few times before it stops. What could it be? It even done it on froyo

That happens to me every once in a while, the whole system will just hang and the menu will come up or the recent apps thing will come up multiple times and the phone will vibrate, then it just goes back to normal.

Could be a bad flash, or some app has created a conflict, seems to me I read there are a couple of apps that caused this. You could just reflash a different rom, see if that fixes it.

From my experience you can get some oddities such as this as a result of a bad flash (which re flashing would correct as stated above) so I'd say your assumption is probably correct and your problem may be with the hardware.
I don't want to ask the obvious question but no one has. Have you dropped it any? Or has it been exposed to any kind of water. I had a phone freak-out on me when usb port got a little wet from some rain.
Just when you think you have it idiot proof, they come out with a better idiot.
not been wet and its not a bad flash. Right now I'm trying out froyo again and it done it again last night. I'm a uscellular agent. And I have yet to have anyone else come I. With the same problem

I believe this happens on an undervolted kernel un areas of extremely low signal. Recently, it seems to be happening on any kernel. I hope this get's addressed in our real froyo release.

Yea, that sounds like it may be the case :s I've had it happen a couple times, but I thought it might just be like my fingerprint is over the button and keeps presseing it. I just wipe my finger over the bottom of the phone and it stops. Don't know if its the same thing.

I think you are right I've had the same issue and if youlook at the soft keys when it happens you'll see that one of the buttons thinks it's being pressed I think it's just a hardware issue cause like you said when you run your finger over the keys it stops.
Also, similar problem every once in a while when I'm trying to swype during a swype it acts as if my finger lost contact with the screen but I definitely didn't lift my finger abd it happens several times in a row until I lock the screen turning the touch screen off it seems to reset the touch sensors.

I've experienced this issue before, although very rarely. Every time it has been the menu button and it always seemed to be in colder weather. I use a thin screen protector I picked up at a USCC store. Happens even more rare with EA11 leak however my screen brightness changes (occasionally) when I end phone calls and am in the middle of an app

I have a strange problem. Occasionally my phone will refuse to let me type a letter. It generally happens towards the bottom right of the screen. However that isn't always the case. For instance I wanted to press the letter N today but it refused to let me. It would press every key around it but it wouldn't press N unless I tried multiple times. I have a screen protector on if that makes a difference. It really is annoying. Is my screen possibly defective?

Sometimes this happens to me when gunk and dirt build up on the screen. Usually I just take my shirt and wipe it off real good and it works like it's supposed to.

Could also be something under the screen protector messing with the capacitance. Maybe a small air bubble that gets pushed out of the way when you repeatedly try tapping there. Just a thought. If it's not a hassle, I would try using the thing for a day sans protector and see if the issue replicates. If anything. it will eliminate the screen protector as a possible source of the problem. I'd gather, if you aren't rooted and running a custom ROM and the problem still exists in the absence of a screen protector, it is a manufacturing defect.

I am having the same problem and have had little gremlins like this come up. My phone is rooted by the way so if it is a manufacturing defect then I guess I am up the creek (voided warranty). It is annoying to say the least my t, y g h and v and b keys react as if they were not on the keyboard at all. Luckily the word recognition helps out but its frustrating. I have had more problems with this android phone than I ever had with my windows HD2. I miss that phone...no worries ever.
I would really advise you to exchange your phone for a new one if you are having problems with the touch screen this early on. Manufacturing defects like that don't go away and can only get worse. You can still return/exchange your phone if you are rooted, you just have to return it to stock before you do so.
This has been happening to myself and several others, and there have been a few touchscreen problem-related threads on here and other forums. the letters I can't type are fairly random but it usually seems to be t, s, and some vowels. it's either a software or hardware issue, since it is completely random and the problem fixes itself when you begin typing another word.
you can also try pressing the letter with your whole finger instead of the tip. it seems to work more often than pressing the letter 20 times before you flip out.
Anyone with this problem, is the touchscreen ever not responsive with anything else?

I thought about exchanging it but after reading all the issues other people have with replacement phones (or their first, even), I'm not sure I want to take the chance especially if it's a software issue.
Happens to me to, I am rooted and running a custom rom. It's a problem with the HTC keyboard. If it happens just hit the back button then bring the keyboard back up. Or install a new keyboard from the market like Better Keyboard.

Not true, had this problem on my Fascinate before the Thunderbolt.
Something stupid to check, do you have wavelauncher installed? That was giving me fits for awhile before i figured it out. anything by the bottom of the screen just wouldnt work.
I have had my sensation for a couple of weeks now and it is proving to be one of the worst HTC phones I have ever owned. I am beginning to become concerned that I may have a faulty device, as my complaints about the phone are really starting to mount up. I will list a few off the top of my head and you can tell me if this is normal behavior:
Unlocking the device: Sliding the ring up to unlock the device can take as many as 3 or 4 attempts at times no matter how deliberately I attempt to do so.
Bluetooth Audio: If I connect to my car for both phone and music, then disconnect, then connect to my bluetooth headphones, then disconnect, then get back in my car, the phone bluetooth will connect, but not the media. This is solved by long clicking the bluetooth connection under bluetooth settings and going into options,then unchecking and rechecking the media box. (annoying and not a problem on either my nexus 1 or MT4G)
The phone is slow: Like way slower than either my nexus 1 or MT4g
Restarting the phone: When I long press the power button and select restart, the phone will turn off... but not back on without several presses of the power button.
Data Connection: I have, on more than one occasion lost my data connection in a 4g area to the point where all data is lost. No 2g, no g... nothing. No icon in the status bar. I have tried entering and exiting airplane mode to restart it, among other things. Reboot seems to be the only solution.
Call Waiting: The phone has, on more than one occasion, refused to let me switch calls when I receive call waiting.
Force Closes: I have received more force closes on this device with a variety of applications, than I have on any other android device that I have owned. To the point where I did a factory reset of the device to see if that would clear things up. It did not.
Line through non HTC Widgets: I get seemingly random horizontal static lines through random non htc widgets sporadically. Sometimes a reboot rectifies this, other times the widget needs to be removed ad readded.
That seems to be all I can think of at the moment. I eagerly await your responses.
Yeah, I'd get it exchanged. That's not even close to a satisfactory experience.
I also get a few unlock attempts.
The data network its extremely slow like 3g our less while on 4g outside with full strength in signal bars.
I also don't get a restart when selecting that and I just sts off completely and have to hold the power button to turn it on.
do you hear a noise if you press in the screen with a bit of effort? I don't know if its just my phone our a common sound.
Sent from my HTC Sensation 4G using Tapatalk
I've had the Sensation since June 8th, I've had the static lines in the Widgets but none of the other problems. My lock rings works every time. I also came from the Nexus One so I never had Sense, I think it's a bit laggy but my apps open up just as fast as the N1. My phone fully shuts down and restarts everytime (I do it daily, it's a carryover from the BB world lol) Bluetooth works great too.
If I were you, I would get a new phone, something doesn't seem right with yours.
I have been keeping silent about it for the most part but I'm in the same boat with you on a few of those things. I don't use bt so I dunno about that nor do I have the line through the widgets issue. But my touchscreen sucks balls. It takes forever to unlock the phone, it just doesn't register my swipe up no matter how slow I go. Also in general my touchscreen is just weak. Tons of my swipes are registered as taps so apps or links are opened. I also have the data stall issue. I have read through the supposed fixes for people with similar problems but nothing fixes my issue. The lockscreen issue started a week after getting it, and happened until I did a factory reset. It then worked for another week before the issues showed up again. My sister has a sensation too and has the same touchscreen issues as me. I have been holding off, hoping htc would send out a big fix update, but damn it is depressing. I have already mentally prepared myself for giving this to my wife in september and using her upgrade to pick up a Hercules. I really hope some updates change my mind.

Can someone please let me know if you can hear the plastic parts of the phone rub when you press down in the screen? I have noticed if I press around the screen with about the same force of scaring snapping your fingers or less the phone makes a sound of what I think is the source between the screen and the edge frame of the phone. I first thought that was the reason why the unlock took a few tries.
either that or I think maybe a small air pocket caused by a spec if dirt was why the unlock want working since its almost right on it. It also works better if I grab the left side of the ring then the right that has that tiny pocket. But still I noticed the huge end call and call button I have to press on it a few times to get a response. I press it far left but near the air bubble that's why I didn't think that would cause any touch problems with the unlock ring.

I am having the lock screen issue , my 3rd phone, all three did it after a few days to a week. I do have the Bluetooth problem as well. I have a jawbone jambox and i can only get media to connect after initial pair. I always unpaired and paired again to fix the problem, i'll try your method next. I think the reason you cant change calls has to do with the touchscreen issues. I am waiting also for an update. The really really messed up thing is that HTC says they know nothing of theses issues, so a fix could be a long way off.
Thanks for the responses. I have had the phone for about 3 weeks and have been holding my tongue. The OP is a copy of the e-mail I sent to HTC that I have yet to get a response to. I will post HTC's response as soon as I get it. I was happy to see that some other countries received an update that fixed a few things, but really I just want to see if CM7 can rectify most if not all of these issues. I have been playing the waiting game, but might just throw in the towel and return it before my 30 days are up (CA).

well, first full reset and retest. if it persists, then ya exchange it. my lock ring is so smooth i pull it up and play with it while bored. spin circles around the sun (weather lock screen) then either let go to unlock or put it back at the bottom. can do the same with all 4 app shortcuts. one flick up with 3/4 of the ring revealed and its unlocked.
edit: phone is 3 weeks old, multiple widgets and full of apps, stock launcher.
I have a stock unrooted i9020A running the Jelly Bean 4.1.1 OTA. I did a factory reset after the OTA came in and reinstalled everything from scratch.
Once or twice per day, the phone will just initiate Google Search (as if I had pressed the little magnifying glass capacitive button) and will repeatedly try to enter Google search even as I am repeatedly hitting the back button to exit Google search. The magnifying glass capacitive button will sometimes blink as this is happening.
It happens when I am using the phone, but I am 100% certain I have not come anywhere close to touching the magnifying glass button, so I know I am not causing it to do this.
It's pretty annoying because the phone basically becomes unusable for 30-60 seconds as it repeatedly attempts to enter Google search and I am fighting with it not to.
Anybody else experience this or have any suggestions?
Thanks.
This has happened to me! On my first NS, my back button would press itself, but it would flash as if I were pressing it. Unfortunately, I never found a solution as a few days later, the screen died, and I got my whole phone replaced as it was still under warranty.

I've been running into this problem as well recently and from the looks of things people experienced this way back to the gingerbread days. I've checked Google forums and people were plagued with this search firing on its own. It is reported by some that when the 3G is low it opens on its own and I can attest to that, that it is happening to me when my 3G it's low.
I had this problem a long time ago and I fixed it by flashing a different radio.
The one that worked for me was UCKF1-GRK39F (this is for my device i9020a). If you plan to change your radio, make sure you flash the correct one for your device.
I have this problem. Radios, ROMs, Kernels, nothing seems to cause or fix it. One thing I would do is lock it then wipe the screen entirely (thinking maybe my finger grease is causing it).. Come to think of it, I've also always had a screen protector on it as well, so that might have something to do with it.
The best solution I've found for mine is to disable the Search button in CM10.
