[Q] Strange screen behavior

Sometimes the screen of my Galaxy Nexus freaks out; it behaves as if I'm touching the screen repeatedly while I'm not. It does not happen a lot, but I think it mostly occurs after pulling down the notification menu and touching a notification message there.
I have tried to reproduce this behavior (camera ready so I can video the screen of my GN), so far no luck. Anybody else experienced this?

Of course, as soon as I'm in bed and have put my camera away I experienced the issue again.
Will try again this evening.

That really sounds like a faulty screen I'm sorry to say. I had a similar issue with my HD2 two years ago, had to send it for replacement.

Hmmm I hope not. Since it's very hard to reproduce I doubt I can prove it in order to get a replacement.

It happens to me only when I'm charging the device. Do you use custom ROM? I'm suspecting that right now.

Nope, stock rom. I haven't even rooted it yet.

Finally caught it on video! It's not very focused but it clearly shows my problem.

I don't think its a hardware problem because I'm mostly experiencing this problem at home. Today at work I used the phone the whole day without encountering this behavior. I'm 15 minutes home and the problem pops up again. Difference? At home the phone is connected to my WiFi. Any thoughts?

Does it happen when you're not holding the phone? I've had anomalies happen before when the phone is on table and not in my hand before. Or could be faulty driver for touchscreen chip.

No, it does not happen spontaneously. I happens when I'm using the phone.

I've read some threads for other devices concerning exact the same issue. There were opinions that it could be due to the static charge that gathers on the sensor.
Possible solution could be:
1) discharge the phone
2) remove the battery and wait for about 10-12 hours.
Try it may be it ill help you.

The phone has a stock image. Also it's not rooted and I haven't touched the bootloader either.

Unresponsive touch screen

Hi all, I recently purchased a nexus to replace my ailing evo 4g today from sprint and it came with a little surprise. The phone is horrible at picking up touch inputs, literally to the point the phone is unusable, like when you physically press the key "n" onscreen and "m" and a backspace is the result; and this happened literally out of the box. If i hadn't bought the last galaxy nexus of all the sprint stores in reach, i would have of course gotten another phone; however when the sprint rep checked to see when the next batch of them come in, there's supposedly a halt on shipments itself of the phone to sprint for unspecified reasons. I really really need some help on this one as im truly contemplating returning the phone and leaving sprint altogether. Browsing the web, I found this (http://forum.cyanogenmod.com/topic/18431-tuning-driver-to-deal-with-unresponsive-touchscreen/) link in which someone tuned the input drivers for more responsiveness on the nexus s. My question is can this work on the nexus? If not, what needs to be done so i can finally enjoy my nexus!??

Return it and get a new one.

No can do for the moment, nearest sprint store with a nexus is too far away. I tried using the kernel fixes I mentioned in the op but ended up not getting any good results at all with the added bonus of having my phone stuck with a stock image which for some reason looks for a sim card and doesn't connect at all?? im shocked at how difficult this is turning out..

I am having the same issue as you, also my phone sometimes just stops responding to touch completely! All the power buttons work so it isn't a software issue, but the screen just doesnt respond to touch input. My question is, what do I do in order to return it and get a replacement?
Do i relock the bootloader and flash back the custom rom??
Im a bit of an Android noob and not sure how to return it compeltely to stock. I am running Francos kernal with a deodexed stock rom and unlocked bootloader.

This isn't my issue unfortunately My screen becomes unresponsive altogether, and nothing apart from a battery pull fixes it. So I called Amazon and am getting a replacement.
Just gonna make sure I got all my data and hopefully this is just a one off
Otherwise I think I will have to go with another device, even though I do love the Nexus
Ps. It could even be a faulty touchscreen driver

I'm sure your replacement will be fine.

[Q] SGH-T989 (T-Mobile Galaxy S II) Issue, not sure if bricked.

Hello! I am new to XDA Developers. I have been reading for ages now, but i had never created an account until now.
I have fully searched this issue with my Galaxy S II and i can't find any answers.
First i will describe what my phone is running.
Jedi Mind Trick V9
Faux Kernel 012
pretty much Jedi Mind Trick Stock, no custom kernel or radio etc.
Second i will describe the situation.
I was making a phone call when suddenly the phone cut off, then i went to look at the screen and all the screen would do when i pressed the power button was flicker in a screen with rainbow colors, (my video will explain visually what this is).
I have tried everything from a hard reset to recovery mode and so far i cant find any answers.
I also opened the phone and swapped the LCD display with an exact model and the same thing happened on the other LCD screen which leads me to believe either something fried on the motherboard or something software-wise crapped out.
The phone has not been dropped recently or mistreated, just used normally with a few wear and tear.
Please i hope someone can help me, as i have no way of getting another phone for the moment.
(apparently i can't post videos yet but if you send me a message i will send you the YouTube link)

Warranty to samsung or T-Mobile

It for sure seems like internal or software issues. If you can't flash a ROM then your most likely bricked. You could use ODIN as a last-ditch effort to get your phone to work. Good luck!!

Problem with charging or hardware. Help?

Hi,
I don't actually know if this is ROM related or kernel related or something just wrong with my phone. My phone keeps 'randomly charging' even when the charger isn't plugged in. The status bar icon changes to the lightning one and it says it's charging on the lock screen.
Sometimes the charger doesn't seem to charge the phone till I reboot (It works perfectly with my Nexus 7 and Tab 2).
I'm running the latest CM10 20120930 with Franco kernel (only because I had the problem with the stock kernel and wanted to try another). And yes, I did wipe everything before updating.
If anyone can help, please do. It's really annoying since the screen turns on every time the phone decides to 'wirelessly charge' and runs down my battery.
Thanks for any advice, tips, etc.

There are a lot of topics about this. It's a hardware problem.
I have the same problem, so I bought this USB port replacement http://www.ebay.com/itm/310412314270 and I'm waiting it to arrive so I can change mine... If it works, I'll post it in the General section of this forum.
If your phone is still under warranty, use it, and don't let samsung tell you that is not a manufacturing problem, because it is, there are thousands of people whit the same problem.
Sorry for my bad english.

I've been using the phone since January so I doubt they're gonna listen. Anyways if you're gonna replace the whole port could you make a how-to so anybody who has the same problem could fix it themselves?

as soon as I replace the port, if it works, I'll post a video and some explanation on how to do it.

Had this problem , sent it back to Samsung and they replaced it and sent it back with a broken screen. Poor customer service but they fixed. As people have stated its the USB port , replace it or send it back under warranty

[Q] Galaxy Tab Pro 8.4 screen sensitivity

Just wondering if it's just me or the screen on the Galaxy Tab Pro 8.4 is way too sensitive. When I try to scroll the page (on Google+ for example) I always end up opening something. It makes me not want to use it. It's really frustrating.
I also tried using a stylus (Wacom Bamboo Solo) and the result is the same.
So, is it only me? Is there any solution for that?

I have the same issue using Pulse. It's been good for gaming though. I might try a screen protector and see if it makes a difference.

Depends on what you're coming from.
I found the S4 to be very sensitive at first but that was from the S2 and OneX. The S3 may have been about the same as the S4 for all I know.
It would make sense if it started in Samsung devices when they added the hover function to their devices. They also made them more compatible with gloves around that time.
I doubt the Tab Pro is much more sensitive than the S4 but I don't own one yet.
You'll likely get used to it very quickly like I did.

The sensitivity on my device was extremely off.
I did little research today. I went to Best buy and tested the Tab Pro 8.4 in the showroom, it performed much better than mine, no issues, "normal" sensitivity... (looks like this issue is not affecting all the Tab Pro 8.4 tablets)
I called Samsung support to find out what's going on. I was told to do a reset on the device. I did it through the Samsung recovery - full wipe.
Now everything seem to be "normal". Looks like that solved my problem.
BTW, I'm using HTC One (replaced my old S2)

I have the exact same problem.. The screen is way too sensitive and I hate using this tablet. I wish I could return it. Thought it was just me. A very slight flick and the page zooms to the bottom. sometimes touching the screen causes I to zoom in and out to the places I don't even know where it's going.

Same issue here. Way too sensitive at the moment. I end up tapping the ads or opening unwanted links when browsing the web.

Try to do the factory reset and post your feedback after its done.
Do it in the recovery mode.
1. Power down your device.
2. Hold Volume Up and Power at the same time until you see the Samsung logo appear. Then release.
3. In the recovery mode press Wipe Data/Factory Reset.
4. Reboot and wait for few minutes untill everything loads.

Thanks! Made it a little better but still kind of annoying. When scrolling through youtube videos, a video starts playing when I didn't intend to click on that specific video.

My Tab Pro 8.4 has the same problem making it almost completely useless. When scrolling it constantly opens wherever I lift my finger. It's also constantly zooming in & out. I tried the Wipe Data/Factory Reset twice with no resolution. I didn't use it much the first couple weeks as I was waiting to get a case before using it and now it's too late to return it to Best Buy. I wanted to love, it but I find myself never using it now. I also tried adjusting the Press and Hold delay.

After I did the Factory Reset I noticed some improvement, but I'm still not satisfied with it. On top of that I started noticing the digital noise coming from the speakers (reported by other users) when I open a game and mute the sound.
And just like like you, I don't want to hate my $400 device.
I decided to send it to Samsung for repairs. I'm shipping it today.
BTW Best Buy's return/exchange policy sucks!
I went there after 25 days of purchase to ask if I can exchange it and they said:
"no, but you can bring it to the Geek Squad and they will take a look at it for a small charge" :/
We should definitely have more than 15 days to return/exchange faulty device!

Opening those ad pages on websites and opening random videos on youtube is getting really annoying. Samsung needs to provide an update asap. The screen sensitivity makes this tablet useless.

just got my Tab Pro 8.4" 32GB today instead of the Tab Pro 10.1" which i returned.
was a bit nervous about the sensitivity problem. but after playing with it for about 1 hour I can say its perfectly fine..

My 8.4 is the same, way too sensitive.

I have this same issue, too sensitive.

Same problem T325

same issue with hong kong version.
I flashed unofficial cm11, it improved the problem, but it still happens. so I assume this is a hardware related? Then I tried us and china official roms, make the tablet unusable. This is too bad. I want to love this tablet, but samsung just ruined it.

I had the same issue across all 4 devices (multiple exchanges for the speaker issue).
I found that If you install a screen protector it minimizes the problem. So I would give that a go.
