[Q] Replacement Digitizer Problem

So I finally replaced my cracked screen and I've been having issues with my new digitizer. It's one of the LG digitizers, not the ones that say T-Mobile at the top. When you touch the extreme left side of the screen, it acts like you're touching the extreme right side of the screen at the same time. It's very weird - when I try to capitalize, it also backspaces, and my a's all have l's after them - stuff like that. It's like that all the way from the top of the screen to the bottom.
I got in there and cleaned a couple of specks of dust that I had accidentally left between the digitizer and LCD screen and it didn't seem to help. I used compressed air to clean the contact where the digitizer ribbon cable connects to the motherboard and tried to get the ribbon cable itself to sit under the motherboard nice and straight (I had a little trouble with it the first time and it could have been crooked, I guess, but I'm not sure if that would even matter.) I've also tried soft reboots, removing the battery, full wipes, and even have experimented with a few different ROMs. Acts exactly the same.
What do you guys think? Do I have a bad digitizer or is there something else I could try to get it to work properly? Thanks!

I buy broken phones of Craigslist and fix them. I have put digitizers on 4 g2x as of yet never had that problem. I'd make sure the connections were nice clean and seated correctly. I see you've done that so my conclusion is that you have a faulty unit. Run a calibration app and see if that helps

I had bought a digitizer with the LG logo on it and it was not as senseative to the touch and as well when touching the left or right sides of it where off a little. I used the ones with the T Moble logo and all works like new.

Hi, my screen cracked, so I got a replacement digitizer and installed it. When I reassembled the phone, it worked fine, except the buttons at the bottom (home, back, etc.) and the bottom 15% of the touch screen do not register. The rest of the touch screen works fine.
Do you know if that part is connected differently from the rest of the phone? Or any other reason it might be broken.
This may be dumb on my part, but my package didn't come with adhesive, so I used superglue. Could that be messing up the sensor somewhere? Or is it not likely that?
Any thoughts/comments would be greatly appreciated.

You probably got some glue in the wrong place. I used 3M double sided adhesive, that way I could be exact with the placement

Superglue + Electronics = BAD!

Hah what he said.
You should never use glue of any sort on electronics. If the manufacturers don't do it, then you surely shouldn't.

SPen tight fit in the slot

Does anyone have this problem? I think it's only on the newer devices because my old Note 10.1 didn't have this issue. In addition to being a tight fit in the slot, the pressure sensitivity didn't work very well until I sent it back to Samsung for them to adjust the potentiometer. The pressure sensitivity now works great but it's still a tight fit in the slot.

This is affecting the S Pen sensitivity! The lines I draw are skipping instead of having continuous pressure. It was the same problem which was the reason I sent my S Pen to Samsung to get the potentiometer tweaked. After it was fixed, the S Pen worked perfectly. The force required to remove the S Pen from its slot must've messed with the nib. It's happening again!

[Q] Any forklift drivers experiencing this problem too?

Hi all, I'm a forklift operator and I have a problem when I'm on my lift. I set my phone down on the tray, which is directly above the battery by about 10 inches, and the screen will randomly turn on by itself. If I'm off the lift, I don't have this problem. I'm no electrical engineer by any means, but is it possible that 2 ton, 1875 amp-hour battery is giving off enough of a magnetic field to trip a sensor somewhere in the phone? There's plenty of wires and metal, but it's really the only thing I can think of. My old EVO 3D did this too sometimes, but I chalked it up to being a bad ground somewhere along the line.
Anybody else share this issue on their lifts or similar machinery?

The nexus 5 does have the smart cover sensor so that is likely the behavior you are describing but I wouldn't have expected a fork lift to be giving off that strong of a magnetic field to interfere with it

as alex said i dont think its the forklift....
this is most likely linked to your proximity censor...

The smart cover sensor is magnetic. It shouldn't have anything to do with the proximity sensor.
It's just weird why it's triggering your phone.
Your forklift could use some form of magnetic resistance for lowering which would might explain the triggering

I've seen all sorts of proximity to random items trigger the hall effect sensor using magnetism. It's fairly common.

Magnetic hydraulic servos on some forklift, very strong localized magnetic fields in places.

Appreciate the replies. I tested the magnetometer with STools and it does seem like there's a magnetic field towards the front of the lift. At least, the lines moved a lot more. So when you say magnetic resistance, makes sense. One more question, does anybody have any ideas of how to potentially block it? I plug into a speaker while I'm working so that's why my phone sits there. The brass gets real uppity about earbuds.

You'd need a Faraday cage or the like, then you'd essentially have no cell at all.
Grab a BT speaker perhaps, some crank out near 100 watts an can be heard easily in a small cab wirelessly.
Or a longer patch cord.

notepro sleeps intermittently and then buttons are disabled

hi guys,
not sure if you're facing this issue.
i recently bought a protective cover, and after fixing it, noticed that the device is behaving odly.
it sleeps intermittently during use (as if you pressed the on/off button) and when you press on/off to turn it back, the home button and capacitive buttons are not functional. Back, home, and the task buttons can't work... after a few minutes of on/off, then it's ok.
however, when i take it out of the protective cover, it doesn't happen.
any of you have that problem?
Thanks.
Regards,
Liang

Yeah, I've experienced this problem too. I have a case that can flip the orientation of the screen. It seems that if I flip the tablet around the capacitive buttons come back. Very strange problem. I hope they can fix it in an update.

Hopefully the sensitivity of the magnetic sensor that controls smart cover functionality can be reduced via a software update. Until then being cognizant of it and realizing what orientation we have to keep our cover flaps away from to keep from triggering the screen off feature is all we can do.
Some cases have weaker magnets than others.

hi,
the cover i have does not have magnets.
where exactly the sensor that tirggers the sleep?
thanks.

The sensor is approximately 1.75 inches to the right of the G in the Samsung Logo and 1.5 inches from the top edge of the tablet.
Have you run a paper clip along all surfaces of the case/cover to determine for sure that there are no magnets embedded within either side of it? Magnets used for the on/off functionality in covers are thin and hidden inside the cardboard that is within the fabric/leather linings.

thanks... but what exactly am i looking at? or is it internal?
you reckon that it's the magnet that's causing this? funny, it was a cheap case, will run through a clip along the surface and check it out.
thanks

The sensor is internal. If you pass a magnet over that spot it will toggle the tablet screen on and off.

[Q] Note 12.2 stylus / screen problems .. help needed

hi ..just got my note 12.2 from pc world .. was actually undercutting amazon so couldn't resist
anyway ... the bottom of the screen about 3 inches in when you try to draw a straight line you get a curved line and in two directions so its almost forming a circle of some kind .. ive just tested my stylus and my girlfriends edge sylus and mine of my note and it is doing the same thing .. however when you use your finger the curving of the lines does not happen ... so its obviously stylus related at this point of the screen only
has anyone run into this problem and do they know how to fix it .... or do i need to take this tablet back to the retailer as faulty ?? does something need to be calibrated ?? i havent seen an option to calibrate
picture attached of what its doing

Are you're using a case that has a magnet? If the answer is yes, take it off.
The Spen uses a magnetic sensor. Anything with a magnet in it will interfere with the pen.

Thank you for your information on that one .. i take exposure would not cause any permanent damage as lots of cases are magnetic ??
of course thats annoying as i bought the case to protect the note .. from possible drop damage and now i cant really use it much when drawing on the note now ... this one has a bluetooth keyboard so was quite nice from amazon
anyway thanks a lot there my girlfriend and i were panicking .. lol
the magnets are a top flap magnet to keep the case shut with the keyboard and i think one at the back that holds the back stand in place

What case is it exactly?
