[Q] Weird grid after replacing touch screen digitizer - Defy Q&A, Help & Troubleshooting

Hi All,
Been a while since I've visited since purchasing a Nexus 4.
Anyway, my Defy had a cracked screen so I got a new touch screen digitizer to put in it so my daughter could use it.
Got it installed just fine, without any issues.
However, shortly after installing it I noticed this odd grid showing up on the screen. It's only visible when the phone screen is dark colored.
You can see a photo of the grid in this post on Google+. EDIT: Also attached the image to this post.

Anyone have any ideas why that grid is showing? It's not a big deal, as my 3 year old daughter hasn't even noticed it. But if I were still using that phone it's something that would drive me insane. I'm mostly just curious as to why it's there.
Thanks!

I can't be certain but I also had the digitizer replaced and right away I noticed the grid. From what I understand each square is point to recognize touch. From looking at your pictures I would say that mine is not as prominent and I only see mine in lighter screens. I'm going to say its because it's not an original motorola defy replacement because when I compare with my other one (yes I have 2) there is no grid at all and the capacitive buttons are very different looking on the new one. I'm still trying to decide if I can live with it or not cause sometimes it does bug me.

Bottom of Screen Does Not Calibrate

I recently purchased an MDA off ebay from another member on this site. They claimed everything on it was fine, but upon receiving it I found that the bottom of the screen didn't respond. After playing with the calibration I found that the bottom of the screen wasn't completely "dead" it just thinks its being tapped on a different spot of the screen. The seller claims this is a software issue, but after several flashes from different roms the problem still persists. Has anyone else seen this happen? And does this sound like a hardware issue?
I opened notes and took a picture of what happens when trying to use the scrollbar in landscape mode to show how off the calibration is at the bottom. Thanks in advance for any help I can get on this.

I had this EXACT same problem. I had the mistake of pushing down too hard while applying a screen protector and it pushed in the screen on the bottom. From that point, I could never calibrate the bottom of the screen. I was able to get a replacement, because I told Cingular that it was broken and it was only a month into my contract.
So, I think the guy probably messed up applying a screen protector or accidently somehow pushed in the bottom of the screen. This is in no way a software problem....deff hardware issue.
Thanks for the response. I filed a claim with paypal for a refund. With the way that it was packed I'm amazed the phone works at all!
Im sorry to hear someone trying to get over on you. Hope everything works out.

Japanese Privacy Screen Protector

Has anybody used these with a pressure sensitive touch screen device and the Touch Pro in particular?
I've never seen one in the US but they're all over the place in Japan. It like a screen protector but when viewed at an angle over ~30degrees from perpendicular the screen is unreadable or black, sometimes with a image on it.
This page shows how it works, the page is Japanese but there's pictures.

The difference is they're stiffer and thicker than the usual screen protector so I wonder how well the pressure sensitive screens like the Touch Pro work. Since the pressure sensitivity is adjustable they might still work good anyway.
There's a Touch Pro specific one for sale here for $8 so I'd think that means it works decently.

And the next question is can anybody in Japan order these up for us? Maybe expansys can buy them in bulk and resell them to us?
I am sure this is nice especially in Japan where it would be annoying to have someone constantly trying to look at your screen so they could watch you weird cartoon pr0n.
Nice find... very nice. I'll try to get a few. You can as well go request this in Dealextreme... if the demand is high, they will consider of getting it listed.
Nice one, I will have a look at the shop on the way home tonight and see how they perform.
Pocketsolutions has them, just not for the fuze yet.

Screen response problems

My mom's G2 got the 2.3 OTA a week or so ago (maybe two weeks), and ever since then she's been complaining to me about her touchscreen being unresponsive.
I downloaded an app onto her phone called "Touch Test" which displays the points of response of the screen, and well, take a look at the rough re-creation in the screenshots below:
When you draw a line like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
This happens:
This is a semi-accurate recreation, but what actually happens is when you draw the line from the top (like say scrolling through something) to the area where the dot is on screenshot 1, the screen registers 4 other "touches" at random locations in that bottom part of the screen (screenshot 2).
At that point, the entire screen except the top half becomes unresponsive, including the capacitive home/menu/back/search buttons, and the only way to bring it back is to lock the screen with the power button and unlock it. The screen then works fine till you scroll again.
I'll try and upload a video of it later this afternoon.
Anybody else seen behavior like this before?
My phone did that to and I had to have it replaced. Something to do with a faulty sensor. Its a known manufacturer defect.

My mom took it to the store today, guy looked at it (luckily, the screen had froze just as we walked in, as she was using it) and said "welp, it's broken. $20 warranty exchange, ships today, 3-5 biz days. have a good day" and now there's a replacement on the way.

LG G2 VS980 Horizontal Lines after Drop

Soooo... My wife dropped her VS980 for the first time in 2 years. All seemed fine (hell I've dropped phones countless times) at least for an hour or two.
We got home and her screen started to do this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So, I researched it and found that insulation of some screen components in the phone are very important to keep insulated. So I popped it open, and it looked fine. But I threw a piece of electrical tape between the components regardless:
Phone still does the lines. A few key notes: Dark backgrounds don't really affect it, turning brightness up high really sets it off, if I cycle the screen on and off it seems to go away, for a few seconds at least, before it starts creeping back into the screen.
Any thoughts? I was hoping if I powered down and left it inactive maybe it would give the LCD time to reset? Sounds stupid though. Could it be anything else? GPU? Bad luck?

Bought a new LCD from Fixez.com. Just arrived today. Hopefully this corrects the issues. I'll let you all know if it does.

UPDATE: The new screen worked perfectly. Took me about an hour, and was able to get it completely changed. Working great now. I hope this helps anyone troubleshooting screen issues!

Blue smudge spot on screen

Hello - my phone is 1.5 years old and suddenly I have faint blue spot on my screen, mostly visible on white background. It's been there for a week ...

Any ideas if there is a way to fix this?
Tap it fast and gently on the 'smudge' for a minute or so. If there is any improvement, keep doing it till it disappears. If not, get a new screen.

Click to expand...
Click to collapse
Thanks for the tip but It doesn't seem to change anything.
If it doesn't spread I might keep it that way because changing the screen would cost me near what I paid for the phone!

could be delimitation, which means you need a new screen.
However try a screen calibration app first.
2nd a factory reset (this calibrates the screen on newer versions of Android)
if that doesn't work you probably need a new screen
The same issue arised for my screen, but it is fainter, think it is screen issue because when I was tapping screen during restart that part had a strange response. It appeared almost suddenly for me, any fix?
