navigation button are not working

Hey
few days ago my HOX ATT fall down. all the buttons were ok but after some days they had stopped working. i have tried to do factory reset but it didnt helped. all the touch screen works but the buttons not. i sent the HOX to Repair shop and they told me they have not seen thing like this before that only part of the touch digitizer working.
can you help me solve the problem?
Thanks.

The fact that the repair shop has never seen it before, does that mean they won't even try to fix it?

He said that he need to order this part to fix it and he even not sure that it will work.
is this hardware problem?

Since you dropped the phone recently, I'd be inclined to say yes.
I'd try to RUU, and if the problem persists, its probably a hardware failure caused by the drop.

Please search the forums regarding LCD changing. It's not an easy task.

You must buy the entire LCD - Digitizer -light guides bundle . It's almost impossible to separe the screen from the LCD, so buying the digitizer is a waste of time if you dont have the LCD.

the same thing for me, i have tryed everithing and not fixed yet, in a few weeks you will see how other parts in the touch screen will not work too.

As javierarenas has said, Purchasing the digitizer alone is a bad idea. Nearly impossible is an understatement. even with a heat gun and an unlimited amount of patience you would be lucky to separate the digitizer from the LCD.
As Redpoint said, if RUU doesn't fix it, you will need a new screen.
Take the phone apart prior to buying the screen. Check the colors of the ribbon cable and try to find the EXACT same screen. This will save you a lot of trouble. Make sure to keep the old screen in case you need to sync the new screen otherwise you are totally screwed.
Good luck.

I tried taking apart my phone and it was not an easy task.....AT ALL! MAKE SURE TO BE PATIENT!

Funny thing is I never had to take mine apart. But did have to reattach the screen, sat down with phone in back pocket and when I pulled it out it had separated the screen from body and had to use some iPhone screen double sided tape to glue back down.

Hi,
The whole thing (LCD and Digitizer) will be replaced and LG will charge you anything between Rs.7000-8000...

[Q] Digitizer not working after reassembly

Hi everyone.
So i tried to replace the cracked screen in a Moto G (I just replaced the display+digitizer+glass module). After the reassembly everything worked except for the digitizer (it worked before when i tested it). I tried to reconnect the digitizer connector (the tiny one which connects the digitizer controller to the display connector ) multiple times, but nothing worked. Has anyone faced a similar problem before?

Hi, I have exactly the same problem.
In my case, it's my second screen, so I've already eliminated the screen+digitizer and the cable connector like the origin of the problem.
Has anyone any idea?
Thanks!
PS: Ening, did you get to solve your issue?

much sad

Bad news. My digitizer cable is damaged. On both original phone and the donor. I was not careful enough: the closer inspection showed it. I am going to order another screen or a donor phone (like a used verizon one or something) and try it again.
So the thing is that the video on etradesupply shows it wrong. You have to unstick the tape covering the digitizer cable connector, then unsnap the clicky thing, and only after that should you unplug the screen master cable (the one that goes into your PCB). Otherwise, it is very easy to damage the touchscreen controller cable (the digitizer one).
I really hope you have a different problem and there is still hope for your phone :crying:

Hi Ening,
How do you check the veracity of the cable connector failure? I think I have the same problem than you, but I haven't a way to check it 100%, because I haven't anyone who can lend other screen to me, and the original screen it's now completely destroyed.
I suppose that I will have to send back the screen to the seller and ask for another.
Thanks anyway!

Hi, i gave the phones to a guy in a repair shop and he looked at it through a magnifying glass

agnobi, I have exactly the same problem, but tested several digitizers and same problem

The flex cable part that connects the controller to the rest of the cable is very thin and easy to damage, you've to be very careful or you're gonna screw it (like the OP did).
ofcourse there is a slight possibility that it came defective, but you should have checked it right when it arrived. So far I haven't seen any incomparable ones, but who knows.....

I think there is something else.
On my side, the 3 digitizers (old one + 2 new) give me same result.
The I think the problem should be on the mainboard or a hardware/software blocking ... or maybe something we didn't re-assemble well
and little question : what is the role of this part (see my photo) ???

Probably the last :>
That thin metal plate makes connections on the back of the PCB (its mounted right between the display and the PCB) and I think it connects to mass.I got no idea what it's role is (prolly its a fitting or some sort of heatspreader).I've assembled one phone without it and it worked just fine, but I've put it back afterwards, just for the sake of being complete

and your digitizer works fine ?
I think also that the issue comes from the connection PCB-patch or as you said software digitizer blocking.
So I 'll try to flash a retail rom to see it .... ...... The digitizer still not working

I've replaced 9 digitizers on 9 different moto g's.None of em had any kind of these problems.This leads me to the conclusion that you've done something wrong.
The worst I had is 1 dead pixel on one of the new displays ( I'm using digitizer+display+frame assembly ).

very interesting your experience ...
the strange thing is that we are several persons to have the same problem and the same symptoms ...:silly:

I've unsnapped the connector as they said in the video of etradesupply...
Maybe I've forgotten something.... you have followed this video ?
Edit :My screens are working except for the digitizer.

I've also reflashed a stock ROM ... no change
so it's not software/firmware related ...
so it's hardware

Never, all worked the first time and afaik they are still working fine.Gotta mention that the ones I`ve used are chinise ones, but look and feel like the original, even the glass feels like gorilla glass 3, altough I don't believe that's the case :>

I have a huge scratch down my screen and the local mobile repairing guy quoted £55 to replace.. I thought this was a bit steep.. I expect him to use real gorrila glass 3 @ that price

finally I've just fix my digitizer
It was 1 or 2 pin twisted on the right so there wasn't a contact between the PCB and the patch....
denseye I think your black screen can be fixed, you may see the pin on the left...." Bon courage " PM me if you have questions....
I've got now my earpiece which crackle but I thinks I'll not try to fix it....
Good night

You mean a pin on the pcb connector where thé LCD câble goes? (Français???)

A pin means a spindle which links the patch(LCD câble) to the PCB.There are many pins which compose thé connector.

Huawei Y511 does show only blank screen(white)

I have separated before minutes the digitizer from LCD and i dont see any broken or wrong with LCD.
What is the reason to not see a Lighting when put to charge? Is that a software problem/missing?

have you tired to enter download mode or heaweis equivalent

kinda need a little back story here

I work in service and the truth is i dont even remember if the display was showing correct, but maybe it was.
I have purchased digitizer and lcd from Ali and the digitizer is in me > just wanted to make the phone full functional.
What key combinations to try?

Is there the possibility that the display foil has gone off with the glass?

New (to me) Gear S3 Frontier, with black smudge on screen - suggestions?

Hi all.
I just received my Gear S3, an ebay purchase, and really happy with it. I knew about the issue on the screen, and as such, the watch was a lot cheaper than all others available.
How would I be able to sort the issue out?

If you make an hard reset that mark continues to appear?

Oh , I think I have seen this issue somewhere, don't have the link, but I am pretty sure its because the battery inside the watch is expanding and putting pressure on the LCD/OLED panel, I would suggest getting warranty repair or change the battery.
Either way get a warranty repair going. Though if you want to repair it by yourself try tracking down that thread, I believe it was on reddit.

Yes, I agree... if battery blows up... then pressure is really amazing...
But my Z1 Display was not missing Pixel... it was only little bit darker... Display moved to Touch glass closer...

Oh so you CAN see things, just darker? That really does sound like the battery is putting pressure on the display ( like putting pressure on a computer monitor screen) .

If you go to Service Center... IMHO they will tell you repair between 250 Euro and higher...
So you can buy new one...

Edit 1.
Maybe for "easy" test it would be enough to remove 4 Y Screws from Backplate/Rear Cover...
And if drunken enough... You could remove carefully Rear Cover...
Maybe this is enough to lower the pressure...
