Vertical Touch Screen Issue - Epic 4G Q&A, Help & Troubleshooting

This is really odd, but for some reason, I can't use the touch screen on my Samsung Epic 4g if it's not open. I have to BARELY slide the screen over (maybe half a centimeter) and then it is reactive to touch. But this is kind of annoying because the screen wants to pop shut.
However, if I open it to landscape mode, then the touch screen works fine. Anyone have any ideas as to why this is a problem?
Thank you so much!

Could be a loose wire that doesn't connect right in portrait, take it to a Sprint store and let them take a look at it.

I took apart the entire phone and checked everything. (had gotten something clogged in the microphone) It's all connected very smoothly.

Have you tried ODIN? If it's a software issue ODIN will fix it, and if it doesn't at least you have isolated it to hardware.

[Q] Wife Claims Ghost Buttons During Calls

So whenever I talk to my wife she always ends up hitting buttons on the screen. (mute, speaker, etc) I told her that the screen should automatically turn off and that maybe something was wrong with her device. As soon as I got home I tested it and it worked just fine. I couldn't get it to happen, light sensor was very responsive.
Somehow she manages to hit buttons and I have no idea how. I covered up the light sensor and tried hitting every button/screen area and nothing happened.
Has anyone else experienced this before? Is there something I can settings/mods wise to help?

Another funny thing is she said her boss at work has the same problem (female) and her husband has no issue.... Ha! I don't think they have Evos though.
my wife was having the same problem and we narrowed it down to her hair causing interference with the screen sensing that her face was against it. dont know if that makes sense but seemed logical to us and now that she tries to be aware of it and move her hair out of the way the problem doesnt seem to exist. hope this helps.

Weird! Does the screen actually turn on then? I should watch the screen next time she makes a call on it.
yeah the screen was turning on while she was using it. i think whenever she would basically readjust the phone against her head it would happen if the hair would cause interference...again i'm not claiming this is some scientific answer but its what we found seemed to be causing issues for her

I see, thanks.
My wife had the same issue...earrings.
Yep, Yep. My wife has the same issue but I've never had a problem. I'm going to show her this thread so that at least she knows it's not just her. lol.

How would the earrings affect it?
I think it's actually the proximity sensor being highly in tune to how close it needs to be to the ear/face. It takes very little movement of the phone during a call to trigger the sensor and turn the screen back on. They probably don't even realize they're moving the phone as much as they are.

During a call, I pulled the phone away, moved it around, etc and watched for screen to come one. It did not come on easily. I don't get it.
I need to watch her during a call and test some things.
My sis has the same issues with the moment, and I tried it out and it was fine. She does seem to use it outside her hair and does have a lot of earrings. Though this is the Moment, it still runs android and has the sensors. I'll let her know and see if she'll enjoy her phone again lol.

Still not sure what the issue/solution even is.
She picked up my phone last night and accidentally hung up on the person during the call! I didn't get a chance to see what happened...
She's starting to hate these phones. I need a solution.
Not a joke...but are these ladies blonds? At start of thread I was thinking hair color or earrings too. But earrings shouldn't impact the sensor as it is up top of phone and earrings would be down toward the screen.
But...if their hair was very light color...and they had phone only loosely pressed to head, I could 'guess' that the hair had enough light reflecting through it to set off the sensor.
Another thing to check on the earring side....what part of phone contacts first...do earrings hit the screen before head covers up the sensor?
My wife had dark brown hair :x
My wife too. Dark brown hair. With and without earrings. Swapped out one device, same problem. She even made it happen on mine.
I have seen it get in a mode where the proximity sensor seems to get reversed. Near head, screen on, away from head screen off. A button gets pushed at some point and then when the screen is on you can't un-mute, un-speaker, or answer a returned call from the one she just hung up on.
I think we are going to have to get her a different phone
I have the same issue but it only seems to come up with AOSP ROM's (Cyanogen & UD)
If I call Sprint and hit the prompts followed by putting the phone to my ear it presses other numbers. I think there is a delay in the proximity sensor that's causing this. I don't have long hair and my face is clean shaved so it's not that.
If I go to show someone that when everything works perfect. It's like when you call tech support for Dell, Netgear, etc. It works when you're on the phone with them and when you get off it doesn't.
I've noticed this in the past. If you are talking on the phone and you cant it just a little bit away from your ear, towards your face, you can see the backlight come back on. Also, hair can carry a static charge. So if your ladies cant the phone and the screen turns on, their hair could trigger a button press.

[Q] how does the touch screen work ?

After the sprint service reset my phone and killed my calender, I got an automated message asking if my problem was resolved. Well then I pulled over and brang up the dialing pad on the screen and started trying to press the numbers but as with 90% of the time they do not work. I started licking my fingers and pressing on the display and started *****ing and my 17 year old daughter asks my what I am doing , she than says why don't you calibrate my display. That would be great if there was one! She has. An lg touch and hers has one but mine don't she asks? Now I need to know how to make mine work before I poke my finger through the screen. I can't even hang up the phone 50% of the time. Is there a secret way to use this touch screen or do I just have to use the right finger and licking my fingers to make it work just ain't right.
Capacitive touch screens, do not need to be calibrated, unlike their cheaper cousins, and if you are having accuracy issues you need to either Odin the phone or bring it to Sprint and let them do it.
http://en.wikipedia.org/wiki/Capacitive_sensing
Licking your fingers?!? That's totally unnecessary good sir/ma'am. Capacitive screens work by picking up the electrical charge that we have in our bodies. So when we touch the screen, that charge is sent to the display, the sensor and cpu do their thing and figure out where the screen was pressed. That's why you can't use the screen with gloves on (like winter gloves). Anyway, it just sounds like the phone is acting wacky.
Have you just tried rebooting to see if that fixed it? Or turning the screen on and off a few times? My phone acts weird on the lock screen sometimes and just turning off the screen fixes it.
There are a few threads here that address accelerometer problems but if the screen is just not picking up your touch, you may want to take it to Sprint.
that would be sir and it is just one of many problems my phone has. I reset it ,sprint reset it, I am crossing my fingers I got a dud . I was suckered onto the shorter waiting list and had the phone since launch day and in the beginning it was told to me by radio shack that android 2.2 was shortly comming and was going to fix all these problems I am having. I love the phone when it is working correctly but now I am just tired of the issues and promisses not being fullfilled. I read the article in the posting and it explaines different kinds of capacitive tec, gut wich one does the epic have. my wifes epic is so sensitive that it senses 1/4 inch away at times. mine is a luck of the draw and her phone is not mine so I dont use hers enough to see if its really better. I *****ed to sprint enough ,and it took this long, that they are sending me a new one. I doubt they are sending me a new one and expect they are sending me a refurbished one to test. I want to make sure its not something like my fingers not having enough energy to sense or cosmic rays are making my page back button go wacky by itself at random when texting or browsing.
Lol, if cosmic rays are bombarding your phone, we all have a lot more to worry about than the responsiveness of your phone! Sounds like you may have just gotten a bad phone. I would be pissed if Sprint tried to give me a refurb phone. There's a command somewhere in the scripting history on the phone that will tell you whether the phone is refurb. I don't know how to do that. I bet someone on this site does though. I guess the bottom line though is that the phone just needs to work.
And to your wife's phone, yes, the phone can be extremely sensitive. Sometimes, I swear that I didn't touch the screen but the screen registers a touch just because my finger was really close to the screen.
Finally, you may want to flash your phone. If you are not comfortable using ODIN or adb, get Sprint to do it. And not just a factory reset through the settings menu. I mean resetting the phone through recovery or download mode. Good luck.

[Q] bizarre screen glitch

When closed my screen works just fine, and when I open for the keyboard it STILL works just fine, except that the whole screen shifts upward, so that part of the taskbar is actually off of the screen. If I open it slowly it seems like about at 10% open the screen flips horizontal, as it should, but then at about 80% of the way open the whole screen shifts upward until part of it is offscreen. Its not nonfunctional at all, but it is a nuisance, especially when playing any games I have the hardkeys setup as a controller. I've tried a full wipe and rom re-install and that didn't fix it. Also it seems like I've had to do a factory wipe more than once recently because the Home and Search touch areas have stopped working. Is there a weird software glitch going on or is my touchscreen on the way out?
I'm either going to just replace the screen for 35 bucks because its already kinda screwy, but if that won't also solve the weird screen shift issue ill just buy a new phone, any ideas?

Ok - so I think its hardware because the screen shifts even when the phones still booting. Would a new lcd fix this maybe?
Sent from my T-Mobile G2 using XDA App
I had the exact same problem. Your issue is in your ribbon cable, I was able to get my phone replaced but if that isn't an option for you, you can buy a ribbon cable and follow a very easy tutorial to install it
Sent from my Bulletproof G2
awesome, I've taken apart the phone a few times before, so now that I know the issue I can repair it finally! thank you so much for replying!! Which Ribbon cable are we talking about?
It is the ribbon cable that connects the screen to the keyboard through the z-hinge. I've never replaced it myself, but if your phone is completely normal closed and then distorts as it opens, then it definetely sounds like the ribbon cable has bad contact as it's stretched. It's really one of the only things it can be, if it were your lcd then the distortion would persist even in portait I would think

I must agree with the above poster, seems like its the ribbon too!

[Q] Scrambled/garbled screen on T-Mobile G2 - flex cable problem? Please help!

Hi all.
My phone's display has been getting progressively worse and worse over the past couple weeks. Initially, when I flipped out the keyboard, the screen would get garbled. I could technically still interact with it (it still responded to stuff), but the display would start glitching out and move all over the place. It's like there's tons of scanlines and it repeats the same display again and again.
When I went back into portrait mode, things were fine. This was extremely awkward but I dealt with it because I had little choice.
However, over the past couple weeks, the problem's gotten progressively worse. Holding my phone a certain way would cause the screen to glitch up again. It came to a point where I had to flip out the screen and keep the flex cable positioned a certain way so I could see the screen. I'm using a dull edge to kinda poke that flex cable around and it helped me gain use of the phone, but today it's gotten so bad now it refuses to "undo" itself when it boots and no amount of poking and prodding of the flex cable will help.
It looks almost exactly like this guy's phone (not my video):

Pictures of how my phone looks right after bootup:

A few seconds after bootup:

Luckily, I was able to get a VNC server installed on the thing, so if you guys think it's a software issue, I may be able to get it to do something, but I'm not going to be able to interact with the phone if I put it into Clockwork Recovery mode, so doing a hard reset is out of the question.
I'm having a flex cable come in and I'm going to get some local assistance disassembling and installing it, but before I do that, had anyone had this issue before? What did you do to fix it?
best guess is you need a new flex cable

[Q] keyboard issue..

Im brand new to HTC products im usually the galaxy guy and the ATT rep convinced me that the ONE M8 would be the way to go today since my S4 got stolen last night ... however i am generally pleased with the device i was wondering if anyone else has issues with the keyboard in portrait orientation. Long story short the HIGHLY used keys on the left side of my keyboard will not recognize my input using my left thumb... i have to literally take my right thumb across the device to input the E, R, T, and sometimes even S keys... is this something I am doing wrong or does anyone else have issues like this ( seems like its almost not sensitive enough to read the input or something i can hit it 100 times with my left thumb and nothing but hit it once with my right and it takes it )... When i turn to landscape to type it seems to do alright but my habits usually keep me in portrait so this is a real irritant if you can imagine. Any thoughts at all or anyone else have a fix for this? Considering returning to the store tomorrow to explain my grievance. Side note... I have tried different keyboards from the play store with the same issue... :crying:
Sounds like a defective left thumb.

Dinstall screen touch test from play, it will show every touch point on you phone. Seems like you have a defective digitizer.

Someone told me that the M8 has a very active screen all the way to the edges... i think ive figured out that its my fat hands that are rolling onto the screen somewhere while trying to type text messages causing the device not to recognize my input. The way i hold the device i guess is the issue because even during calibration it gave me issues with the left sided letters.... so i guess i have to either find a new way to hold the device or get some kind of case to accommodate my fat hands and tight grip on the device .... any tips or tricks on how to hold these things when texting to keep my hands off the screen? I tend to hold the device more in my palms than fingers for safety im a bit clumsy and i think thats the issue.
