[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.

2nd Bad Phone

Got my first CDMA Nexus on the day released. Was running IMOSEYON's Kernel at 1.42ghz and phone suddenly rebooted. Nothing I did from that point on would write to memory. Tried 2 or 3 ways to restore factory image but it didn't clear sdcard (as it's supposed to). Tried to relock bootloader using fastboot and it would say it did so but was unlocked again upon a reboot. Finally returned it under insurance. Had to pay deductible since it was permenantely rooted even though I think there was an electrical problem in the memory write circuit.
Got new phone and all was well until I dropped the thing last weekend on tile and cracked the screen (first time in 4 years of smart phones). Everything still worked, but returned it under insurance after restoring factory images (successfully). Another $100 bucks down the drain.
Got new phone. Set everything up and it started random reboots - particularly when charging. Reloaded CMR recovery that had worked so well. Still randomly rebooting.
Insurance is sending me my 4th phone in a month and a half (free this time). I broke one, but two out of three appear to have been duds. Quality control issues???
Anybody else having this kinda problem? I've used (rooted and rom'ed) an HTC Incredible, Droid Charge, Asus Transformer and Kindle Fire with no (permanent) problems. This is, frankly, disappointing.

HAve you tried using your phone stock without messing around with ROMS or bootloaders and custom kernels?
The majority of problems I've had with these types of devices have been with non-stock units...

It's probably because you are over clocking. Charging and using the phone with an overclocked processor generates a lot of heat. The phone will reboot on its own to save it from frying.

Scan the forums, other than your cracked screen you are describing known or soon to be known issues with the SGN.
I'm also on my fourth SGN. First had a line under the screen that looked like a crack. The next two had the lock up reboot issue and the one I'm on now isn't showing all the virtual SD space that all the others I received had, it's two gigs short.
It appears that quality control at Samsung is not as comprehensive as it should be.

If you want to complain on the phone then you should have stock room, if not you should complain in the rom thread. It sounds as if you have not had problems with the phone itself(on any of the phones), it sounds as if you have tampered with it. If so you shouldn't complain about the phone.

I'm also on my second defective Galaxy Nexus in a week. The first had horrible banding even at full brightness and a glitchy accelerometer or compass. You could open Google Sky Map and sit the phone on a table and watch it jump around the night sky. The new one has a creaky case, a green cluster of dead pixels in the center of the screen, and all of the greys are royal purple. Not cool. Samsung needs to work on their quality control.
If my third is a bum unit, I'm going either Razr MAXX or D4.

The phone would become unresponsive and reboot itself. Sometimes it would say the headset was connected and I would lose the microphone and speakers which was terrible when I was on a call because the other party couldn't hear me any more and I couldn't hear them. It was terrible. Sometimes it would force reboot multiple times in the course of a few minutes. I even tried just running plain stock but it made no difference.

[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.

RMA Failure. Options?

I recently sent my tablet in for repair, and they sent it back seemingly untouched. It came with a paper with my info on it, but under the section listing the issues and the repairs done, both were left blank.
To summarize my issue, it'll randomly freeze during use or idle (not usually idle though) and if I put any pressure on the top left corner of the screen. The freezing sometimes causes screen glitches and after a moment or two, it reboots.
So, What are my options for contacting ASUS and trying to get this fixed/replaced, and what can I tell them I've done to try and fix it that is within the realm of warranty. (Factory reset? Flashed a stock rom? )
Thank you on advance!

ASUS currently has my tablet for the 3rd time. All for the same issue (horrible flickering, screen turning off & on). The first two times they sent it back to me after performing a factory reset only, despite me telling them that I had done that numerous times.
After many many emails/chats/telephone calls I finally got them to agree to not send the device back to me without fixing the problem. I have recorded video of the problem which I e-mailed to them (not sure if that did any good or not).
Anyways, today I finally received word that they replaced the LCD panel and GPS module. My tablet will be shipped back to me today. My first RMA was in October. What a horrible mess this whole process has been.

If you don't mind me asking, who did you email?
From what I can tell all they did was pin a few stickers to my tablet and ship it right back. I'm not even sure they factory reset it. Lot of good it would have done.

[Q] My Nexus 7 doesn't turn on or charge

Hello guys.
I wanna start saying that i found a couple of threads about this issue but none of them was about the 2013 version of this tablet.
Two days ago I was on a plane to London, i turned off my Nexus 7 2013 (the device has at max 3 months and i bought it brand new) that was fully charged.
During the flight I didn't turn it on...when I was at home, approximately 3 hours after, I tried to turn it on without success...tried to recharge it but no response from it...no blinking or steady white light.
Till now I still can't figure out what happened to it considering I just turned it off normally.
I tried all the steps provided by several google official support pages without luck. I also opened the back cover too see if some connectors were not properly attached; no problems there.
I am really starting to think that something broke.
My question would be: I bought it directly from Amazon and I was wondering if it's a problem that I rooted it and I installed a custom rom on it. Is it possible that sending it back will result in having it back myself without any kind of repair attempt?
Thanks to everyone will give this some time

Have you happened to try booting it into fastboot regardless of it not actually starting up? It's a long shot but you could try it.
Also if Amazon can't turn it on either it shouldn't be a problem.

By fastboot you mean the procedure where you have to press volume down + power button?
Anyways i kinda tried everything, it just doesn't respond.
Altough what I noticed just yesterday was that if I plug it to the charger it gets warm on the back, upper part meaning that the power still goes through...
But thinking that this is something related to the battery doesn't feel right...it was fully charged when I turned it off the last time.
I think i should give it back with RMA...It feels like the only choice i have.
