[Q] screen issue....maybe?

I got my charge as a replacement for my fascinate like many others. befor i do anything i wanted to give the phone a few days on stock to make sure everything works fine. So far the only thing i noticed was sometimes it lags when i hit the power button to turn the screen on. Sometimes it flashes a static filled screen for a split sec before home screen loads. also some times it takes a sec for my screen to come back on after i lower the phone from my face so i can hang up. Is this just a little minor known issue others are having or is there something wrong with my phone possibly? Phone is all stock, fully bloated and the only apps ive installed are xbox live stats and google googles (coolest app ever). I doesnt do it all the time but it happens frequently enough to notice it. I can normally recreate it if i hit power button to turn screen off and let it sit a few mins then hit the button again to turn it back on.

When running completely stock, I experienced the same 2-3 second delay. Now that I am on EE4 with a custom kernel, the delay is closer to 1 second.

did you ever see black/white lines or static? I only ask because if its a common thing that most have exp then its really no big deal. ill root and flash to help fix the lag. But if its not then i would like to get it fix asap. Other then that i havent seen any other issues yet.

I see the lines and"static" on mine when the screen comes on. Not every time though.

I have seen it on occasion. It's much less noticable on a custom kernel and ROM.

I have that on mine too.
(Out of the box EE4 stock)

Thanks for posting everybody. It seams like its a common issue then. I just wanted to make sure it wasn't just mine or that i needed to return it due to some kinda of defect. Nice to know a custom kernel will fix it for the most part. Thanks again guys. This phone is so much nicer then the fascinate

I set a lock pattern on my phone, and I haven't seen the screen flicker once since. I'll switch back to the puzzle lock and see if it comes back....standby.
*update* switched back and still no flicker. Maybe that's the ticket.

I have it on two replacement phones I got through amazon . White lines for a split second . I got it replaced through verizon because both of the others had a dead glowing red pixel after about a week. The one I got from verizon works great I would get it replaced asap before u get the glowing red dot of doom

Help please, what are these horizontal black lines?

They only just appeared today, randomly when I took my phone out of my pocket. I've restarted the phone to no avail, and am panicking because I dont know where to begin..can anyone diagnose my problem?

Looks like dead pixels, but the image isn't really clear enough.
Take a screenshot with some app.
If you see that in the screenshot, then reflash your firmware & ROM or flash an RUU.
If you don't see it in the screenshot, then it's a hardware problem.

Thanks, I took a screenshot and it's not a part of it. The lines keep getting bigger and bigger!

Sounds like it needs to go for repair. Is it under warente? Best of luck to you!

I too have this issue. It was present from the moment I powered the unit on. I continued with the setup to see if I could adjust the screen or maybe an update might fix it. But sadly no dice. I'm calling Google tonight to see if they can send me another unit or repair this one.

Had the same problem earlier, when i dropped the phone accidentally.
Observation: It gets darker and grows when the phone heats up, and lighter (almost cyan blue) when the phone cools down for a significant period of time with the screen off.
i had to keep the phone near an air conditioner vent for a few hours with the phone turned off for it to disappear.
once the lines disappear completely they dont return back, unless if you drop them again (which is what i did a few days back again.. and the stupid lines are back )
If you have any other ways in which you can get it resolved pls share with us.
Cheers,

[Q] G2X screen not visible

Afternoon all. I know the title might seem like a BSOD post but my situation is different. I've searched but can't come up with anything.
When I turn my phone on, it completes the boot but the screen never appears. How do I know it's on? Three things, the ROM I'm using, Eagle'sBlood I think, has an engine revving theme instead of standard Android chime. Second,the menu, home, back space and search buttons on the G2X body illuminate. Lastly, if I swipe in the area where I think the unlock icon should be, the phone unlocks. If I hold down the power button and wait for the shutdown notice, I can guess the 'Do You want to shut down' and 'confirm shut down' icons and the phone turns off.
I've tried removing the battery, SD card, sim card and rebooting in each variation but with no luck. The phone has been rooted for over a year and so I tried booting into CWM (powerbutton, down volume). I think I'm getting into CWM fully but without the ability to see the screen I can't navigate.
This started happening yesterday. I was listen to Pandora and using a GPS app to track my run. The battery died during. I plugged it in for several hours but haven't seen the screen display since.
Any suggestions? If this is a hardware issue I'll get a new phone but without being able to see the screen, I'm not sure how to diagnose the problem. Other than rooting and changing the ROM, the phone is stock. The issue I had before this is the battery icon doesn't display. It just shows a battery outline with a ?-mark inside. The battery level only shows when the phone is charging and powered off.
Your help is greatly appreciated.
G2X - LG P999DW

ROM: Eagles Blood (unsure of version)

Really sounds like a dead lcd or maybe just the backlights. I don't really know how the backlight works on this phone but typically if there is video but no light you can put a flashlight onto the screen and barely make out the display around the flashlight. Either way it sounds like hardware.

Twitch - Thanks for the reply. I'm not 100% sure what you mean by backlights though. When the phone is on and the screen is not asleep I see lights around the edges but the screen itself is black. For my own knowledge is LCD and 'digitizer' synonymous? I saw another thread describing how to replace the digitizer for $60-75.
I'll try checking it with a flashlight when I get home.

I know there is an opinion thing but what is a good upgrade from the G2x for a non-hardcore user? I rooted and changed the ROM b/c you guys made it so easy to do, not b/c I was looking for the phone to do more than it already does. Up until this, and the battery display issue, and a wifi issue I forgot to mention, I've been happy with the G2x but there is no reason to spend $100+ repairing a 2+ year old phone that I pickup used off CList in Q1, 2012 if I can find something better on the used market for $200

Yeah I'm not too sure how these phones are set up, I have more experience with lcd monitors and such. But I think it is all in one piece on phones.
If you're looking to upgrade pretty much anything that came after the g2x likely has a lot more to offer in development. Good thing about this phone is everything is an upgrade. I have a samsung galaxy s 4g that's nearly 3 years old and single core but it runs 4.3 like a boss! Aside from GPS...

Flashlight didn't show any screen images. I think the next step is just trying to guess my way into debug mode and connect via uSB to my laptop and retrieve data before dumping the phone or trying to replace the lcd/digitizer. I saw an app mentioned in another post that should allow me to mirror my phones screen on a laptop. We'll see.

Thanks again. Anyone else had this issue?

last chance
Last chance in case anyone has any great ideas. I'll be ordering a new LCD and digitizer (probably don't need both) but would prefer not to spend the coin if that isn't my problem. all suggestions welcome

Hmmm, this an odd and aggravating problem you have here lol. I've ran two versions of eaglesblood, their CM7 version on 2.3.4 and their ICS AOSP version on 4.0.4 and have never heard an engine revving in any boot animation so I'm not sure what rom you're running either. Have you tried the hard reboot? While the phone is on at the home screen (if you think you're there I guess) hold the power button and the volumeUP button and the phone will reboot. I've read on here from a more experienced user before that doing this clears or does something to the caches that makes for a more complete reboot or "reset" of the phone's condition. Try that and see what happens. The only other option I would try to take is to flash a new rom and before doing so doing a COMPLETE wipe (to include format /system) and full instillation of a new rom, gapps and kernel. Can you see any images if you boot into CWM when shining a light on the phone's screen?

Maybe I'm wrong about the ROM. The flash screen shows the android graphic in electric blue and a comet type animation zooms around. During the zooming, the sound is an engine revving. I was using the ROM for 2-3 months before this issue popped up so I doubt it is the cause just wanted to give those more knowledgeable than myself as much info as possible

That's my real problem, I can' t see anything! With the phone on, when I hit the power button and unlock the screen (guessing), the only illumination is the menu, home, back space and search buttons on the G2X body. I can tell from the haptic feedback once the phone is unlocked and I can occasionally guess the proper location to shutdown.
I tried the hard restart (Power, Up) but same result. I've downloaded an app called MobileGo for the computer that displays the phone screen but I can't get USB debugging turned on.
I have noticed another odd issue. With the phone turned on and the SIM card installed, when I call myself from a LAN line it goes straight to vmail. I know the SIM is good b/c I've been using an old nokia candy bar phone with the same SIM while troubleshooting. When re-inserting a SIM card, is there anything the user needs to do for the phone to recognize the SIM? Just wondering if this 'direct to vmail' is another sign of ............something.
Thanks

Sometimes when I take out the sim card my apn gets messed up. Ideally you'd just go into settings and load default apn and it'll work again.

But calling should work.
Seems like a busted screen from everything being described here.
Try connecting to a tv using hdmi... maybe the ROM would allow it to display. Worth a shot.

also if you could get airdroid installed on tthe phone you might be able to do something with that. Cool little app that lets you control the phone through your PC using the same wifi network.

It's alive!!
My phone is alive, or at least it was.
I followed the directions on the youtube video I found to take the G2X apart and the first thing I noticed was the corrosion on LCD connector. I'd already purchased the LCD so instead of cleaning the old we just replaced it. The new screen worked, unfortunately I couldn't get a signal so we took it apart again to clean off corrosion on all the connectors. I'll let it sit for a few days to make sure everything is dry.
Don't be a fool like me, if you're going to do anything with your phone that might cause it to get wet, especially sweat, put it in a baggie or something. I'll post a follow-up if the thorough cleaning does any good.

I'm pulling for ya man, best of luck!

It works!!
The G2X is up and running again! :good:

For anyone else that runs across this thread, unless the digitizer or LCD is physically damaged I'd disassemble the phone and check for corrosion before buying new parts. I used the new LCD but that b/c I'm not going through the trouble of returning a $16 item.
Wi-fi still doesn't seem to be working, which is odd. Wi-fi stopped working two months ago, it doesn't even show available networks, but worked for a few minutes when I originally replaced the LCD last weekend. Both antennae are connected but oh well. if I had to choose network vs wi-fi connectivity, I'll take network!
Thanks again for all the help

Nexus 5 screen died today + dangerously hot lower screen

Went to unlock my phone this morning off the charger and the screen is totally dead. Couldn't unlock or do anything to it or even see what was going on, called Google and ordered a replacement ASAP.
Went through the not fun task of doing a nandroid backup without seeing what was on the screen and doing some trickery with screenshots then backing up my entire SD card.
However, here's the strange and potentially dangerous thing that I noticed later when I got home this evening. I went to look at the phone and go to a fastboot flash with the factory images and went to touch the bottom of the screen. When I went to do so, to the little bit of the left of the LED light was a SUPER hot portion of the phone. I almost burnt my finger it was so hot.
Not sure what to do about the issue, I feel like if I just call the support line they won't actually take in my concern legitimately. Any suggestions?

thats something quite strange
let us know what google says about RMA and this issue

Agree, maybe it's just your phone, maybe it's all the batch. Which batch/model do you have?

On my Transformer Infinity, sometimes the screen won't turn on at all. On a few occasions, if I press Power enough times, I get a glimpse of a message saying the Launcher process has stopped, but then my touchscreen doesn't register any input. The tablet is also sometimes running quite hot at those times. The only way I know to recover from this is press the Power button long enough to force a reboot, then everything is normal. Could this be what's happening? Do you know if the phone is still running under the black screen? Have you tried forcing a reboot, and did it work?
As for the hot phone, I've noticed my N5 does get a bit warm when I'm using it intensively (4G, WiFi, Bluetooth, GPS and screen on all at the same time and in use) but not enough to burn me. Could be hard to tell which component is heating up like that since I think it could be the screen backlight, SoC or battery... Do let us know if you find out more.

I had called them and reported the screen totally dead with lines streaking vertically and got a new replacement ordered. It wasn't until late last night when I got back and had the screen on in this dead mode that the bottom was extremely hot. I'll have to call them back and let them know

Yeah, no its definitely dead. There were streaked lines across it, rebooted it multiple times. I ended up going into the bootloader and recovery via adb/fastboot and all that jazz. It eventually just would not work now.
In regards to the hot part I definitely think it was the lower part of the screen. It was quite literally half an inch away from the LED to the left. Was super super hot then once I shut the defective screen off (I could tell by the backlit light or whatever) it wasn't hot anymore after a minute or so.

Is it black/white? 16 or 32? When did you get it?

32gb black version. I ordered it immediately when they announced it that day.

mine gets really warm when i'm doing a TWRP backup then it goes into bootloop after and wont cool down. i have to force it to power off from recovery and let it cool, but i've always seen it happen. i wonder if yours was attempting to boot over and over for hours and cooked itself.....? i have a launch day black 32gb too, running Cataclysm with Franco at the moment but it was doing it on rooted stock with stock kernel

I had to send my 19 day old 32Gb Red Nexus 5 in to LG for the same reason. I was using the phone and all of the sudden had vertical lines and the bottom of the screen got burn your fingers hot. Waiting to see what LG does with my phone. The only thin I can figure is the synaptics chip which controls the screen is bad. Its the only thing in that area that could get that hot. I also noticed when I first got my phone the glass in the same area looked like it had a slight wave in it. Didn't think anything of it at the time. I'll let you know how it goes.

Is RMA/replacement applicable for Rooted and unlocked devices?

I don't believe its an issue with developer phones as long as the issue wasn't caused by something you did like brick it by flashing a wrong radio or something like that. It has to be a manufacture defect to get it fixed for free.

My device issue is related to power button. there is no software issue.
The power button is rattling since from the purchase of the device.
Hope my device gets repaired.

Like I said. Hardware issues that are production faults should be covered.

[Q] Suddenly, My Phone Will Not Power On

I've tried searching but no one seems to have this same issue. Or where I saw people with the same issue, they just stopped responding to suggestions and no resolution was reported. So if anyone can help me I'll definitely post until the end!
It started a couple days ago: my phone kept switching orientations (portrait/landscape) as if I were rotating the phone in my hands, but I wasn't. It would happen if it was being held upright, or even laying down on my desk.
Yesterday into this morning it got really bad. It would switch orientations literally every second. I started backing up as many apps as I could, but that was incredibly hard because the buttons moved every time the orientation rotated.
I was able to boot into recovery and make a data/system backup from there.
During the course of the day today my phone eventually just shut off. Now it will no longer power up. I have tried booting normally, as well as into recovery or download mode, but it responds to nothing. There is no screen flash; there is no vibrate. Absolutely no response.
I have swapped batteries with a friend who has the exact same phone. My battery works fine in his phone. His battery produces the same results in my phone: no response to anything.
When plugged in the phone behaves the same: no charging light, and unresponsive to any combination of button presses.
So... being that I'm rooted and likely out of warranty, is there any way I can fix this myself without going to Verizon?
Thanks a TON in advance to any replies! My fingers are crossed...

I've been seeing a lot of this (power button failures) lately. Are you on CM 10.2 by chance?

I was on AOKP Milestone 2, which I believe was based off of 10.2. I could be wrong, but it was either 10.2 or 10.1.
But this seems like a hardware failure, no? What would the ROM have to do with it? Not to come off as brash; just curious.

Try getting yourself a USB Jig off eBay or something or make one if you're crafty with electronics.
it should get you into download mode and then you can odin back to stock witch will atleast bring you a functioning phone
good luck
heres a video of the Jig getting this hardbricked s3 into download mode from the same Power on conditions you listed

Great find. Yeah he definitely has exactly the same symptoms as me. Although he bricked it by flashing things improperly. Mine just started out of nowhere.
Hopefully that makes no difference. I don't think I can wait for a "jig" to arrive. I'll probably try to make one myself. Anyone have one near Minneapolis that I could borrow for a few minutes?
I'll keep you all posted.

Well, good news and bad.
Good news: I made a jig. Bad news: it won't revive my dead phone. I tried the jig in an old S3 with a cracked screen and the jig puts that phone into download mode just fine. But nothing will wake up the other S3.
Could the micro USB port be damaged on my phone? What else could be causing this?

Not sure. It was working for a couple months just fine on that ROM. This feels more like a hardware issue...
Being that the USB Jig didn't work, I'm not sure what options I have left. Anyone know how a JTAG works? Would that be an option?
Or am I just hosed?

it might be a faulty motherboard. its like something wrong with the actual gs3. that or your battery is dead. but if not its definately a hardware issue. try buying a new motherboard to exchange the bad one
