[Q] phone functionality - Nexus 4 Q&A, Help & Troubleshooting

This ones a bit strange but ill try to explain as best as i can...
Got my phone last week - rooted, unlocked the bootloader and reflashed within about 10 mins or so - you can't not can you...its what they were made for....anyway, im not sure what's caused it to happen but in the last few days when i dial a number as soon as the number is dialled the screen goes blank (but working in the background as i can hear it ringing....the other persons answers, and then when i want to hang up i cant get the screen go come alive again) unless the other person hangs up and then it does. Ive tried another image but its the same and ive just upgraded the phone radio firmware to the 4.2.2 version but i makes no difference....anyone else had this or is it just me?
Cheers to anyone that has a clue....

Have you check to see if anything is blocking the Proximity censor (top left corner)? The Screen Protectors often do this if they are in the way...
Otherwise the Prox Censor is fudge.. its the only thing that will cause the phone screen to turn off when a call is in progress (this is so your face doesnt press buttons)

is it my screen or the ROM?

hi everyone, this is my first official post on the forums, and well i need ur help on my phone, for some reason when i slide my phone the screen shows like random lines etc, then when i slide it back it does the same, and itll take like a good 30 mins to get the screen right to its proper look, usually itll show like blue, or green, and even sometimes i get that "White Screen" where id see it everytime i slide or slide it back so idk, and even when i soft reset, either the screen is out of line or itll show those random lines again also to add to that sometimes the soft keys on the front dont work at times soo idk if its the ROM i just put in which was from T-Mobile or my screen :/.....i need ur help, cuz i might consider getting the screen replace or load the bootloader....appreciate the help and btw heres my video i just posted to give a good clearance of what im talking about and when i show the phone up close im fiddling with the power button to show how it is, thnx
http://www.youtube.com/watch?v=-2Lnwzqkt8k
im sure its the rom, i used pdaviet's rom and it did that ****. i replaced it with a different rom and it never did it again.
well i just redid everything and EVEN on the bootloader still had the whacky look on the screen...
ok well i put the old rom, the one that came with when i first got it, and still no luck....could it be a faulty screen connection? or the screen dying? and btw the phone has a real irritating noise.... and also on bootup he screen wont be aligned....idk what to do...
God..... Vital information you didnt put in... if you hear the noise, then its a goner. it prolly has a leaky capacitor, or the screen is some how desoldered and shorting out the board.

well whats the best bet? should i get this repaired as soon as possible???? or get a new one? and doubt bout the second reason, cuz the noise stops when my screen is off(of course) and sometimes when its in portrait mode, ya the screen would be on and would be white but none of that hating noise

Some Help... Phone blank screening to a degree

Thanks for reading.
I'm currently using WM6.1 on the phone, and loving everything about it.
Since day 1, I've used a phone lock code, along with PIN1 code.
When unlocking the phone for after say an hours inactivity, the keypad will show, then the screen will go blank only showing the top bar of the phone.
Any press of buttons and screen will just make a beeping sound, and so far nothing I've done will restore the keypad to unlock the phone.
Is there anything wrong with the ROM i have, and is there anyone who can suggest how to correct this?
Please remember, the top bar still shows, and a reset allows the phone to work as normal (once logging back into it of course).
Thank you,
Hi guys,
Sorry to bring this back up, but this problem is still going on.
Not sure how to resolve it, so hoping someone would know how to solve this.
Thanks,
Posted twice for some reason.
Maybe is a sw failure,(50%) try to reflash with this fw: RUU_Hermes_CINGULAR_WWE_3625023_6275_1540700_108_UOOS_SVN05_Ship.exe
if your hermes its from att/cingular. after flash open and close the tap of hermes, if the blank screen continues or return this, the failure is hw (the flex component broken,bus, pcb) in this case you need to buy the spare part or send to sat.
good luck
other possible solution

Hi there,
Its not white screening, or anything else, I think the next time it does this, I'm going to have to take a picture, to make sure it can be understood clearly.
Basically, when bringing the phone out of standby (from pressing off/on button) and attempting to enter my pin into the phone the phone will allow me usually to press at least one number of my pin, and then it'll black screen, where the start bar still displays, but no response.
The handset isn't problematic when being opened for use, or anything else, its just annoying to have to reset to load the phone back up again.
I hope this helps?
Further to the above, here is what i've been talking about...
Happened last night, typically as I was bored, and had to wait till morning to take the photo...
Still no movement on this post...
Would it be suggestable to upgrade the install of WM?
If it is, how easy (will read guides beforehand) is it to do (reasonably, hard etc).
Just this is now my only phone, so don't fancy my chances bricking it.
Thanks!
Sorry to be posting yet again, but this has now happened 3 times a in row since last night. I wouldn't mind knowing if a rom fix would sort this, and if so whats the best rom to go for...
Just keen to get this sorted now...
Thanks.
If it helps, I've nothing running when this happens. The exception of last night, where I was using Audio Manager when walking home, and had to soft reset once in the door.
Hi
I am almost certain you have a software fault here and need to reload a new ROM - take your pick - my preference is schnaps - it isnt that hard to do and should solve your problem
Just go to the Windows upgrading section on here and follow the process - you will be happy

Screen No Response but Occasional Response HELP

Hey I have an elf the T mobile version 64/128mb , phone has been working for 8 months now all of a sudden it wont respond but the call and end call buttons work fine the 4 way navigation key only work when lets say you go into the call records by pressing the green call button. You cannot do anything besides change time, answer calls and hang up. Please Help Tried hard reset soft reset, and the phone is unlocked to all networks using the network key method.
this looks a hardware problem may be the LCD or the digitizer
Is it fixable by software or maybe opening it up to fiddle ?
It is not the LCD, it is only the digitizer (the thing that is responsible for the 'touch') I recently had the same problem, until 1 week ago I purchased a new digitizer off eBay for $15.
Do not get LCD and Digitizer, just the digitizer to save money.
If there is no cracks or damage to the screen (bad cracks, pixel damage etc) you only need a digitizer.
I have a video I made of me changing mine which I'm editing atm. I do have photos.
This is the correct response. It is not software if it started to work occassionally and then stop, this is what happened to mine. 99% it is digitizer!
Thats cool please email me link [email protected] for your video I will order one now.
http://www.google.com/search?hl=en&...nge+digitizer+htc+touch+youtube&aq=f&oq=&aqi=
See the 3rd result.
Hey I read its going to ttake 14 days for my digitizer to come , in the mean time is there a way I can bypass the touch the screen alignment page when you first boot up?
you can get www.mymobiler.com
Cheers.
Tried it but requires you to accept the installation on the phone any other ideas?
Thats weird, mine doesnt.
it will auto install.
It says on the little status box installing mymobile to the phone then it dissappears saying not connect. this message comes up everytime you try and run it.
Sorry, I ran out of brain juice.
You have to stick with this for a while than, and bear the bitter pill.
MyMobiler should be able to install onto the phone itself.
But I really wonder why this doesnt work.
Hey thanks anyway found this whiel browsing aroudn on the internet fixed the problem it aligns the screen for you http://216.139.221.18/downloads/mobile_speak_pocket/release/MSP_RemoteAlignment.zip

and it does auto install its the part where it asks you to accept remote.exe and you have to tap yes or no for it to run on your device, havent bypassed that yet but atleast I can just accept calls and check texts but let me know if you have a solution for the whole remote.exe thing

HELP desire z screen wont turn on

Hi everyone, I got my desireZ back in November and it has been working perfect ever since, i have it rooted using VISIONary and everything was perfect until today. The phone was in my pocket and i was lsning to music, i looked at my phone and all i saw was a white line going from the top of the screen to the bottom, i pressed the power button to turn of the screen, then i pressed it again and now all I see is a black screen with the back light on.
I have tried to soft reset the phone, took out the battery sim card and left the phone for a while, came back turned it on and still the same thing black screen with the back light on... The touch screen works fine i still hear the phone receiving txt msges and emails, i can even receive phone calls, and answer them by sliding my finger across the screen like usual.
I am trying to do a hard reset of the phone but i can't do that cause even when i turn on the phone while holding the volume down key i still dont see anything on the screen
any help would be appreciated.
EDIT - after trying to open the keyboard a couple of times, now the screen turns on white... when i press the power button to turn of the screen and turn it back i see a fading effect where the screen slowly turn on from left to right (fades from black to white) and then stays white till i press the power button again....
Since i have rooted my phone, i dont belive i can take it to bell to fix it the way it is... and since i can't see the screen to perform a hard reset to remove the root (i dont have s-off) ... does anyone know of another method for doing this? maybe with connecting to a computer?

There is another thread on the forums about someone having the same issue. I believe there is a solution using adb on your PC to connect to the phone.
Not sure how 'tight' your service provider is, but if the screen is dead, and you are still under your warranty period, they may simply swap the device for you after doing some 'basic' tests and dump it into the bucket that goes back to the factory for refurb. The fact that it is rooted won't be discovered until much later, if ever, so it may not be an issue.
Good luck!

I am suffering the exact symptoms as the OP with my Desire Z which is rooted with visionary rom flashed - I would really like to know how to use adb to resolve this !

HD2 Black screen after a call?

Is there a fix for this? No matter what rom I use, Didn't try Froyo, but after receiving a call, the screen stays black, so I spam the hard keys to wake the screen after about a minute or so. Can anyone help?

I have the same problem with 2 HD2 phones. Not aways, but most of the time. I ask this question before - http://forum.xda-developers.com/showthread.php?t=1349809 , but i didn't get the answer.
May be it is hardware problem, but if it is it's gonna make me a problems every time.
If you figure it out, pls PM me.
Once in a while i have the same problem, but when I clean the screen (until it looks shiny ) and it gets better…
(I clean mostly the top of the screen)
I don’t believe it is the “solution” but works for me…

If you push the End button (or any other button) before clean the screen, what happens. Does the screen stays black???
I think that this is a software problem, because other ways every time when I press the End button (or any other button) it will give me Nothing.

I have the exact same problem. I am using the SD card android version. I've tried different ROMs, but with all I have this problem. When I boot into WinMo I don't have this problem at all, so it doesn't seem to be hardware related.
I can use the phone with anything else without any problem using the SD android version, only when I recieve a call or call out myself the screen blacks out and the phone seems unresponsive. After about 30 seconds to a minute the phone shows the lock screen.
I would love to work with the Android version for normal operation but because of this I still boot into Winmo within office hours...

Your better off doing what I did. In Android, sonewhere in the settings for calling, change the sensor to off so it never blacks out. In Miui rom its in program's, then calls.
Sent from my LG-VM670 using Tapatalk
Task 29 and start fresh. Only thing that got rid of it, test when you first start the rom to make sure it works normal, then start adding your apps and such.
Or increase the 125mhz CPU settings to 245mhz under cyanogenmod settings/performance/CPU or governor settings.
Sent from my HTC HD2 using Tapatalk
my screen stay black (off) when i take the phone away from my face EVERY call as well. this is what i do and it works everytime.
1.)pull the phone away from my face (duh)
2.)starting with it facing the sky, i turn it to face the floor (when i say facing i mean screen up ... then screen down)
3.)as soon as i turn it back over (screen face up) it turns on
im thinking its a sensor issue??? either way it works and i dont go on a hardware button mash fest to turn my precious leo back on.
if this helps please send thanks ... if not tell me im crazy :-D

I just download this apk and will try it ....
But I think it's hardware problem (may be with the sensor), because when I turn back on Win Mobile 6.5 i have the same problen ...
I think to bring the phone to service
... when I take it back will tell you what is exactly the problem ...
Task 29 then install windows, next install the right radio version , finally install the android
like dragonovus say´s try completly reinstalling android.
and please feedback here
BUILD.PROP baby!!! there is a tweak for this and i believe it works( in the prop ) dont know exact address but google "build prop tweaks" also use setCPU and set the lower number to about 350+ also try to use the end hardware button less cuz this has been addressed in another thread..... the button sticks or sum crap..... i use zmooth and never use the red end button........... good luck
Will try all, but now I use ' Screen stays on '
Sent from my LG-VM670 using Tapatalk
well ... for me Screebl Lite didn't help me
Reinstalling Windows is not necessary. Just make sure you have the right Radio and HSPL then do a task 29 before installing Android. But your problem is most likely hardware related. The end call button is most used and therefore prown the wear and tear... Try using the red end cal softbutton. I guess you only have that problem when you use the hardware button right?
In that case it's the problem with the button and not the software...
And at the end did anyone of u solved this? If u need help post reply or pm me. I think i have a solution for u.

Yes, man! I have the HSPL2.08 and radio 2.15.50.14 ... I think we all do. I can't use the soft buttons, because I can't see them. That's is the problem. The screen is black and won't lights up. May be I can't read you ... but I try to run back Win Mobile just to check is it from android OS or the sensor...
build.prop does not help
I tried the build.prop thing. I added those 2 lines at the end of the file:
ro.lge.proximity.delay=25
mot.proximity.delay=25
No change, still a black screen after any call.
Any other idea ? How to completely deactivate the proximity sensor ?
Fixed !
I finally fixed the issue by removing the screen protector sheet and cleaning the upper left part of the screen with a dry towel.
It works fine now. It was just a problem of the proximity sensor not being exposed enough.
I hope this helps.
