[Q] Dead pixel..? Or not. - One (M8) Q&A, Help & Troubleshooting

Hey guys. Been having my M8 for almost a month now and I just realised 2 dead pixels about 2 weeks after use. So I did a little bit of Googling to see if anyone else was facing this issue and found that there's some kind of fix by downloading Dead Pixel Detector / Fix apps. Problem now is, I can't see the 2 dead pixels when using the coloured screen (tried all the colours) provided by the apps but I can still see it when using the phone as per normal on some dark backgrounds. So I'm not sure if this is really a case of dead pixels or.. something else.
[Edit]
Oh btw the reason why I'm asking is because I see some people claiming they managed to fix the dead pixels by using these apps so if I could fix mine, then I wouldn't have to send it in for repair

Stuck pixels constantly show 1 color, and you can try to fix them with the app.
Dead pixels are white and there's usually nothing you can do about it.

Ahh.. So I guess mine are stuck pixels then. Cuz one of them is always green and the other is always red. So I guess it's safe to say they're not dead pixels then.
Then that brings the other issue of not being able to detect these pixels using the app but still able to see them while using the phone normally.. Any advice?

Run the app for a long time, it might unstuck them.

Tried that for 30 minutes (as set by the app) alr and still no fix. How long should I run it for?

Graphical glitches in browser

Has anyone else spotted graphical glitches in the address bar when pages are loading. The letters disappear and are replaced with a garbled mixture of green and black pixels at the left of the screen.
Difficult to capture unfortunately

My device does similar but with a few white pixels and is on anything that is using the GPU, so basically everything lol. Might be your phone as I haven't found anyone with my issue

Yeah I've had this on the stock browser, the words go all distorted for a few seconds. I guess its a bug within the internet app as its only happened on the browser for me.

As long as its not just me, I feel a bit more comfortable. Doesn't bother me I would just be worried that it is indicative of an underlying graphics problem

I get the exact same thing...more of a visual nuisance than anything else really...I don't let that bother me as much as the fact that WiFi at home stops working randomly with full bars and connection status showing as Good...

Happened to me a couple of times. Only happens with stock browser. I use chrome so not a big issue.
indeed, why not try a different browser like Dolphin HD or Chrome? Dolphin has some serious speed improvements in its current beta, and thus soon in its official update. Video comparison: http://lifehacker.com/5919626/dolphin-browser-gets-even-faster-is-still-the-best-browser-on-android

Turn off auto-brightness, and power saving.
whats weird
thanks for the advice... i tryed but its not it.. i know what u mean were it can go from light to dark.. but this is a very quick flicker of the screen.
could this be kernel related or even hard ware... im gonna try stock kernel.. im using faux 009.. this didnt happen on the 003 kernel...
faux says not all chips are created equal...just a guess... id hate to return for a refurb phone.. when this is my only problem...
time will tell... i was just wondering if anyone gets this very quick flicker.. not a shift in brightness......

I rarely get them. Once in a while if I am switching from an apps to home screen via home button . I see the main apps on the home screen flicker very quickly once.
I think it started happening when I installed the wicked rom red. Before I was full stock . Matter of fact while typing this message I seen it flicker twice.

If you are in your 14 day period, I would exchange the phone.
This seems like a hardware issue, not a software one.
If the flicker continues then it will only get worse.

[Q] [!Data recovery!] waterdamage/black display/no touch/no auto usb storage.

I did do a search, I couldn't find anything directly related to my problem as it's not how to fix the phone, but how to recover my data in this specific situation.
Alright, so I went to Dublin, got absolutely smashed, and dropped my new One X in the toilet. It's working fine - turns on, buttons light up, goes to what seems like sleep mode and waking up when I use the volume buttons, all seems okay except my display is ****ed - black, sometimes with streaks of visibility but nowhere near enough to see what's going on. No touch either.
No-one will touch it and I don't care so much about the phone, I just want all the pictures I took from my drunken holidays. As HTC so intelligently decided on internal storage instead of SD cards I'm a bit at a loss here. I can connect my phone to the PC, but the default behaviour is 'charge'. With the update that came out a while ago it defaults to USB storage when plugged in (or so HTC customer service says) but I rooted it and ran CM10.
What I need is a way to force USB storage through the PC, or a way to do a full backup of the phone without having to turn storage on. I'm not sure if this is possible? I'd appreciate some help here!
(It's dry now, was about two months ago, also I don't need advice on how to get it fixed, I'm not interested in paying for this as I'm going to give it away for spare parts and buy a waterproof phone)
Thanks in advance guys!
How about usb-debugging, enabled or not?
Are you currently on CM10?
Sent from my HTC One X using xda app-developers app
Oop's that sounds bad but I'd be happy to help you to get your photos off. Firstly have you rooted yet? If so you could get it into recovery mode and with help from a friend or another phone then you could activate the usb mode. Also I'd be happy to take it off you for spares as I have two hox's in my house.

USB debugging.. I'm not quite sure. I think it was on. I am on CM10 but as I said, can't see or use the display at all..

I've already promised it to a friend of mine - I am rooted, running CM10 but even if I get it into recovery I've no idea what I'm doing as the screen is completely black so it doesn't really help. How could another phone help me, I don't know anyone with a smartphone as we're all insanely good at drowning them in alcohol.
Can you confirm that you have clockworkmod installed?
I will soon return with directions on how to mount USB storage using only volume and power buttons.

I do yeah! Thank you
Okay, here's a little guide:
Hold power and volume down for 25 seconds. Do not let go even if it vibrates.
1xvoldown
1xpower
Wait 20 seconds
Connect USB to PC.
5xvoldown
1xpower
8xvoldown
1xpower
The sdcard contents should pop up on pc. If not, reboot and do it all over again.

Just to make sure, I don't hold power, just one press, then wait 20 sec, yeah? And I disconnect it first. ..Annoying, it ran out of bettery. I'll let it charge a while then try it out and return to the thread. Thanks a lot

Correct, begin the process disconnected. Only hold in the beginning, all the other steps are single taps.

Have you checked if they are on your sim card? They might also be synced to your google account.
The only thing I know is that they are not on the sdcard. They are probably stored somewhere in /system/.
It could be possible to retrieve them through shell commands, provided that your phone has usb-debugging enabled.
Imma do some research and let you know if I find anything useful.
In the meantime, leave the handset to a bag/box of rice for the night. I have once recovered a dead display by doing that.

They aren't synced to google, only my old contacts, and they're not on my sim, that's the first thing I checked of course.
I did find com.android.contacts folder, but it's empty, or hidden system files. Thanks a lot. You are BRILLIANT.
Really.. I'll give it a shot, it's been a couple months though so I doubt there's any pee left in it.
I did find out that /data/data/com.android.providers.contacts/databases/
has some info, but I believe that it contains only the entries that are already synced to google. Not very useful.
Oh well. I'll try again tomorrow.
If any of my dear colleagues knows something about this, please drop in.

Screen flicker in sun with keyboard popped up?

I have tested this with two of these phones and it is confirmed there for sure. I live in Miami Florida there is a lot of Sun here so I have no problem testing this. Within any app if I am in the Sun and it is directly hitting my screen and my keyboard is popped up my screen flickers it's not a super bad Flicker it's light but it's definitely there looks like your screen is blinking really fast. I'm going to try on as many of these devices as I can but can anyone tell me if they are experiencing the same?

I definately recall seeing it. I know exactly what you are talking about. I don't see it anymore so either my kernel (ktoonsez) fixed it or it was a bloat app.
I can confirm the issue on my I9500. Its not only limited when under the sun, also happens when you turn the brightness level all the way down. I'm still on stock kernel, maybe custom kernel may solve the issue. No settings in stock has mitigated or fixed this issue for me.
The people who are seeing this, have you turned off "Adapt Display" ?

Yes, just as the lock screen comes up, but then it seems fine. Strange.
BS...
u mean with the screen facing the ground? or the volume buttons near the ground, im confused, maybe a pic/vid would help
The launcher FC'd but after acknowledging the event everything is fine.
A video showing the issue being reproduced may be useful so we can identify it.
The second time I tried this I noticed when the glowing x was about to be replaced with the lock screen the x dropped to the bottom center of the display, as if the height on the display was two times the actual size.

I got the glitch, but it didn't really seem to affect anything on mine. It straightened itself out almost immediately and the normal lock screen came up.
I noticed this glitch today, but like the others said it doesn't really matter much since it corrects itself right away.
I wouldn't call it a "glitch", more like an annoyance, that happens to the Nexus 7(2012) as well. The bootanimation/logo is supposed to be portrait, but as the tablet start up it tries to move to landscape mode, but since it's a portrait image it moves that way, making it look like something's wrong but it's not. You can change the lockscreen to not rotate and stay in portrait or don't hold it landscape while it boots up, in that way you won't see it again.
Edit: Also happens to the brightness level, it's just the tablet starting up.
