[Nexus 5 Q&A, Help & Troubleshooting] Madzy:
Static screen and freezing

Hi All,

Need help here with my 6 month old Nexus 5. It has been pretty good with no issues but since last evening, it started behaving weird. The chronological events are as follows

1. While browsing on Chrome some websites were not scrolling intermittently. This was only in the browser.

2. After about 10 mins of the above behavior the entire phone froze and didn't release itself. I had to force reboot by holding the power button down for about 10 secs. When the screen came on, it was the static screen

3. I again pressed the power button a couple of times but no use. Held it again for 10 secs, then phone rebooted and everything was fine.

4. Continued to use the phone and everything was normal until this afternoon, when the phone again froze while browsing a website

5. Since then the phone screen shows the static and if I press the power button once, the screen switches off and press again the screen comes on with the display showing properly. I can now only perform one touch which is registered and the screen freezes. If I switch off and on again the next screen / action is shown which is the action I did in the previous touch. Every time it registers one touch and I have to switch off and on again to see the next screen. Sometimes the phone just shows static and I have to wait a few seconds (30 sec) before using it again.

6. If I make a call to my phone, I hear one ring and then it is busy tone like I've cancelled the call. However the phone does not show the incoming call.

My phone has been intact and is well protected with screen guards and case. There is no physical misuse / abuse of the phone. I managed to shut down the phone and enter recovery. Here as well it only registered one touch, though the phone was processing and moving the next step. I somehow managed to initiate a factory reset through the settings, but no use.

Now in about 2-3 hrs the phone has become completely useless. I'm uncertain what the problem is, all my touch inputs are registered and processed. The screen just doesn't refresh to the next and requires a power off/on. I picked up this phone in the US and now in India. So I can't RMA the phone and I don't have warranty for this in India.

Any suggestion will be greatly appreciated.

I'm getting the same issue. Tried soft and hard reset. Opened her up and seated all cables. The issue is still persisting. Is replacing the USB flex the way to go?
[Nexus 5 Q&A, Help & Troubleshooting] nexus565:
Hey I have a nexus 5 32GB and the screen started to do weird things and now it isn't working at all. Its the same in recovery mode also do I think that it's not a software problem.

I think there is an issue with the motherboard. Please help me out.

Thanks in advance.
[Nexus 5 Q&A, Help & Troubleshooting] Elluel:
Most likely the flex cable

Anyone seen this colored screen?. I have been getting this past 2 weeks when phone is charging and screen is about to turn off. I am on stock not rooted.

[Nexus 5 Q&A, Help & Troubleshooting] KGAN5:
Same thing, Screen now black. Won't turn on...

Hey everyone, I know that this is kind of late to the thread, but I have what I believe is the same problem as everybody else here. I had my Nexus 5 in my pocket for maybe five minutes, and in between the times that I put it in my pocket and took it out again to reply to a text, the screen went all colorful and static on me (Red tint, almost as if I had twilight on, but I didn't). I tapped the back, and the colors went back to normal, but the digitizer wasn't responding to touch. Then, It went black. No color, the speakers weren't working, neither was the backlight on the display. I took it apart, and figured its either the USB flex cable (which looked frayed), or the mainboard. If its the USB flex cable, then I know I can repair it. If it's the mainboard... well, as a sixteen year-old who has no current source of income, I'm out of a $400 phone.

Pictures attatched. Thanks!
[Nexus 5 Q&A, Help & Troubleshooting] Madzy:
I took the phone the LG service center and the technician seemed to know this issue and immediately said that the USB flex cable needs to be changed. The entire fix took about 5 mins and the phone is working fine since then.

Sorry for the delayed response.
[Nexus 5 Q&A, Help & Troubleshooting] pezkiln:
I hate to necro up this thread but I'm having similar problems to the op with my nexus 5. About two weeks ago I saw my screen get grainy just like the op and many others mentioned and then the screen went completely black. The screen still "turns on" but it's just black with the backlight on. I can hear notifications and other things and I'm hoping that all I need to replace is just the flex cable. If it's a problem with the logic board then I'm screwed basically.

Anyway that's my story. Bought the flex cable and it'll be here by tuesday so I'll find out then if I'm lucky or not. Fingers crossed.
[Nexus 5 Q&A, Help & Troubleshooting] squirrelcity:
Hey man, did you ever try this out and get it to work? I have the same problem and was thinking of trying this out but wanted confirmation first.

Thanks!
[Nexus 5 Q&A, Help & Troubleshooting] Nicky J:
Just wanted to post here to say that this thread just saved me a lot of money!

Had the same issue (static showing on the screen). Local phone repair shop told me it needed a new screen, without even looking at it(!), and it would be £120 + labour. Told them I would think about it, and came home and did some more research, found this thread. Ordered a replacement USB flex cable from eBay, and fit it by following a YouTube tutorial, and now the phone is back working fine. brilliant!

Thanks xda!
[Nexus 5 Q&A, Help & Troubleshooting] Djblue82:
I had a problem where my screen looked like an old CRT TV with particles flashing all over on anything with a static dark background. Any ideas
[Nexus 5 Q&A, Help & Troubleshooting] joshzz28:
Hey guys I had a similar issue on My 32GB Nexus 5 but all I had to do was boot into recovery blind and then the screen showed the android bot and then from there I attempted to wipe and do a factory reset but it was taking very long after which the screen flickered a bit and then I long pressed the power button and it restarted as good as new!

Regarding the flex cable that could be the issue but for now it seems to be working perfectly fine.
[Nexus 5 Q&A, Help & Troubleshooting] sugar shane:
I'm having a similar issue as everyone else here, my nexus 5 just went from a good screen to an old TV with no cable connection one night. I just read all the post and believe I have a spare USB flex cable in a spare n5 at home. I will try it out and post the results since there hasn't been a lot of resolution posted here. Cheers, long live the nexus phones!

UPDATE: Used the USB Flex cable from my "spare parts" Nexus 5 and it worked like a charm! I have looked multiple places and this seems like the most likely fix, if not the only fix for the static screen issue. Cheers guys!
[Nexus 5 Q&A, Help & Troubleshooting] :
Anyone used a repair shop to fix your phone with this issue? How much did it cost?

What's strange is that the issue came back a year after I used LG warranty to repair my phone with this crap. How the heck this flex cable gets broken? Looks like it's a flawed design from the start and this is bound to happen sooner or later.
[Nexus 5 Q&A, Help & Troubleshooting] T1xq3:
I have the same problem, it is not the flex, display or anything but port on motherboard where flex plugs in, if you press on it you can see the changes
[Nexus 5 Q&A, Help & Troubleshooting] direktive4:
ive had the same problem for the past couple of days and am waiting for a replacement flex cable to arrive. hoping it's not the port on the motherboard, since that probably means having to a buy a new phone altogether

[UPDATE]

flex cable swapped and nothing changed :(
[Nexus 5 Q&A, Help & Troubleshooting] Mkingxiii:
i did the same thing and mine will work sometimes, if i disconnect the cable while its running then reconnect it, but my board has slight watter damage. has anyone tried reballing the chip that handles the graphics processing on the board?
[Nexus 5 Q&A, Help & Troubleshooting] elkir:
Solved for me by fixing connection

I've solved similar static by reinforcing the connection between the motherboard and the daughterboard.

There is a bigger discussion on this topic on ifixit.com but I can't post a link to it yet.

[G2 Q&A, Help & Troubleshooting] robson2222:
Could you check your phones and tell me if you have different tints in left bottom corner and right bottom corner? You can see that on white background or transparent black background. Tint in the left bottom corner is more blue and in the right more yellow. Maybe it is connected with little backlight bleeding in right bottom corner? I hope you understand me.
[G2 Q&A, Help & Troubleshooting] Infinite Jest:
I have found the exact same issue on mine (noticed it the second I received it in the mail and powered it on). Most noticeable when your on screen buttons are white or you have a gray keyboard, the left half being blue tinted. I'm going to try a replacement this week and see if it's any better, but it looked like a store model had the same issue. Attached is a pic in which you can make out the subtle blue tint in the upper left corner of the photo creeping its way along the edge of the phone. I'll report back when I have a replacement. Otherwise, this screen has much better calibration than the display units and is less blue overall.
[G2 Q&A, Help & Troubleshooting] mrm43:
Replace with warranty.
[G2 Q&A, Help & Troubleshooting] Infinite Jest:
Have a black replacement on the way. I tried to get a white one as Verizon released it after the black version in hopes of getting a newer display batch, but the guy wouldn't do it. I'll post an update on Friday or Monday when I receive it.
[G2 Q&A, Help & Troubleshooting] paniczklos:
And? :)

I have the same, but for me it's more a yellow tint on the top that blue on the bottom ;)

It's visible when you have your keyboard on, while in vertical mode. The left of the keyboard is yellowish. I had the same thing with Z1, so maybe it's a "thing" with LCDs ? ;p
[G2 Q&A, Help & Troubleshooting] Infinite Jest:
The replacement exhibited the same behavior to a lesser extent. However, it also has a huge spot of dead pixels, so I'm waiting for another replacement . I think the blue at the bottom is a panel design flaw but the gradient at the bottom from left to right varies from unit to unit.
[LG Optimus G (International)] j0e74:
After having some problems to unlock the bootloader and having softbricked my E977, I got to unbricked it with KDZ UPDATE TOOL, but something went wrong and I managed to get 25 out of the 32Gb of space. I guess it has to be a partitioning error with stock rom I put when unbricking it. Anyways, I decided to install Cyanogenmod 11 nightly (NOT STABLE).

So I did root it with Framaroot apk

Then I unlocked the bootloader with FreeGee via

installing TWRP recovery and choosing normal/classic mode to unlock it.

Everything went fine this time.

Downloaded the last nightly in Cyanogenmod page for e975.

Downloaded Gapps.

I did put these two zip files in my /Downloads directory and proceeded to reboot in recovery mode.

There you do a wipe in data, cache and Dalvik.

Then flash the rom and the zip with gapps in that order. Reboot.

You can flash SuperSU also, but installing from play store did no difference for me.

This is optional, if you want NFC to work fine: Downloaded the patch here, and then with any root explorer or any other you can change permissions, copy it to system/vendor/firmware and change permissions to "-rw-r--r--" reboot and NFC should be working fine.

Download Cyanogenmod 11 NIGHTLY

Download GAPPS

AS USUAL, IF YOU WANT TO DO THIS YOU ARE DOING IT AT YOUR OWN RISK, AS I DID!
[LG Optimus G (International)] cyraxx84:
It is normal and you will always have only 25 of 32gb, the other 7 are for system. I would suggest you to choose the new unlock method in freegee instead of the classic one because of that "dead battery" thing.

Btw. its better to do a full wipe, means format system too.
[LG Optimus G (International)] j0e74:
That's what I been told about the other 7Gb. The new unlock method (the mako thing?) in freegee left my phone soft-bricked, so I tried the normal/classic method and it worked fine. Should I do it again?

What about that "dead battery"? So far no problems with the battery, unless you mean something else.

Thank you for your notices.
[LG Optimus G (International)] cyraxx84:
Yes that mako thing, but if all is working its ok. Problem was(classic method) when your battery went empty before you put in for charging it's sometimes hard to turn phone on again. On new method freegee uses now mako bootloader and that one works better. But if everything is ok let it as it is.

[Sony Ericsson Xperia Neo, Pro] Dagh:
Hi everybody,

first let me say thank you to this incredible community that saved my phones many times.

I received an xperia neo mt15i that is bricked. When I turn on the sony logo appear..after xperia logo and restart in loop mode. I don't know anything about what have done the last owner but I suppose he tried to change rom and made some mistakes. I tried many guides with flashtool, with emma, with update service..but nothing works. The point is that the phone is not recognised when I've to connect to start the process. If I press the back button when I'm connecting the cable a green light turn on (blue with menu botton) but is not recognised. What I can do?

Thank you very much!

P.s.: Sorry for my English !
[Sony Ericsson Xperia Neo, Pro] martinusbe:
Are ADB drivers correctly installed on your pc ?

Have you tried with another phone ?
[Sony Ericsson Xperia Neo, Pro] Dagh:
I think that could be. I've downloaded the flashtool and in the folder drivers I started the program flashtool-drivers and installed all the drivers (just in case ;) ) it's correct? I've to do other thinks ?
[Sony Ericsson Xperia Neo, Pro] martinusbe:
cant be windows 8
[Sony Ericsson Xperia Neo, Pro] Dagh:
I'm using xp so I don't think. Few weeks ago I installed the adb drivers for a lenovo p770..maybe I've to uninstall it?

[7" Kindle Fire HD Q&A, Help & Troubleshooting] bagels6969:
If anyone could help, i'd really appreciate it. I was successfully able to root my kindle, but after rooting i tried installing TWRP via adb it never came back after it's final reboot. I have a fastboot cable and even with it, the kindle won't turn on, doesn't show up in devices on either linux or windows. Does anyone have any ideas how to recover it? I'm thinking that the bootloader is somehow missing or corrupt in a way that even fastboot doesn't work.

Also, if it is not recoverable in it's current state, is there somewhere that i can get a replacement system board to get it back up and running. I'm very technically savvy and am completely comfortable changing system boards, i'm just not familiar with android bootloaders enough to know how to fix this.
[7" Kindle Fire HD Q&A, Help & Troubleshooting] stunts513:
If it hard bricked, which it probably did, you can either replace the board or wait for kurohyou to map out the emmc contacts on the motherboard like he did the kfhd8.9 and kf2, and you can do some soldering and reflash the boot loader from Linux. Otherwise replace the board.

For me they most do not work but some are proved to be working only a few and by few I mean REALLY FEW :)

The system scans build.prop for the lines ( those build.prop tweaks you add are merely placebo ) because they are not in Android's Source Code

In simpler terms the system scans them and renders them invalid so skips them they absolutely do nothing :) in my opinion
