My wiza200 touch screen intermitten - G4

Hi all,
Has anyone experience with a problem when the touch screen intermittently works, especially when you press/hold hard on the sides of the face of the phone. Without pressing down on the side, the top menu (start... x) most of the time are either unresponsive or respond as if you press elsewhere on the screen.
I'm thinking of open up the phone later tonight to troubleshoot, guessing the screen digitizer is loose or, HOPEFULLY NOT, cold solder somewhere. But if you'd heard or faced this problem before or even have an idea on what has caused the problem, I'd like to hear from you. Please help!
Thanks!

Adding info
Oh yeah, did I forget to say that not just the top of the screen, the middle part as worst. The only part of the screen is still responsive is the bottom. If I press down or punctual around the face of the phone tightly enought(?), I'd be able to have the good touch screen for a little while (5... 10 minutes) before it gone weird again.

Fixed... for now
Well, I jammed a couple of thin plastic to the bottom of the screen within the housing facelet behind the t-mobile logo... and it works... for now.
I still intend to disassemble the dawn thing as soon as I realize such quick fix has become unpractical or no longer work.
I will check back to this post again, so if you are interested, don't hesitate to reply, I'll try anything when desperate.

How long have you had the phone?
How do you carry it around?
If you got the phone recently and started carrying it around by putting it in your pants pocket, then you find the screen sometimes doesn't work well, those facts are related. A couple of years ago people used to always complain about this, and some recommended rubbing your finger firmly around all edges of the screen for a temporary fix. Others recommended forcing a business card under the metal at the edges of the screen. I got a leather belt case for mine, and the problem went away.
If you've had the phone for years and it just now started acting up, the problem might be related to a cable, connection, or something. There is a wizard service manual online. I've used its instructions to replace a screen, with no bad issues.
Good luck with your phone. The wizard is a bit old, but still pretty nice.

[Q] NEWBIE HERE! Really F'd my HD2 up!!! HELP!!!

So, about 2 weeks ago, I got my HD2 off of Craigslist with a cracked screen. It worked perfectly fine with the exception of the hardly noticeable cracks. I knew I could get the replacement digitizer/screen for $40-80. I got my screen in the mail yesterday and, following the "YouTube" video tutorial found on this site, I......ugh.... replaced the screen....................I SCREWED UP BIG TIME!
First, I broke the ribbon cable for the Side "Volume Up/Down" buttons. Then, I broke the ribbon cable for the "soft keys." Ah, crap, but oh well. I figured I could use the touch screen for pretty much everything i needed to do. Well, while prying the cracked digitizer screen from the LCD, I went a bit too deep & peeled the tinted film off of the LCD. I thought nothing of it at the time. I'd already done enough damage. So the display would be a bit brighter than normal oh well.......WRONG! I put the phone back together and once I get it to power up, all I get is a white screen. I thought I missed something. So I disassemble & check 3 more times. Still a white screen.
Well, after all of this, the new digitizer/screen doesn't want to stay in place very well. So, being pissed off and curious, I pull it out and away and notice in the backside reflection of the digitizer that I can slightly make out the phone display. So, apparently the "Tinted Film" that I accidentally peeled off of the LCD makes images visible on the phone screen. I kind of damaged this film when peeling it off. Therefore, I am unable to put it back on. Does anyone know of a simple fix without replacing the LCD?
SORRY FOR THE "SHORT STORY LONG."
I was brainstorming and thought that maybe the film was polarized. So, I grabbed my sunglasses, which are polarized, and wearing them, I can faintly see the display. Anyone think maybe polarized window tint might fix my problem?
Hey man I have some electronic devices that need repair, can I send them to you to fix them?
SURE!
You can pay me in HD2 parts.
Sir i can only say 1 thing. search ebay and replace everything you damaged. only that way you will get your hd2 in perfect state.

I'd go one step further and say bin it and get a new one!
You sound just like me. That is why I never try things like that anymore. Hope it gets sorted but might be better looking for a used one.
I've got it functioning...
I found the film that I ripped off, put it over the screen and........I CAN SEE! However, the top half has lines through it. So, I must've damaged the LCD. The good news is that my phone is useable again. I just have to do everything via the touch screen and can't let the screen hibernate unless I have my charger close by. I'm just gonna keep my eye out for a cheap busted phone and eventually have a 100% phone again...
I sympathize with you. I broke HD2 while I was trying to check for loose WiFi card cable(cuz i was getting weak WiFi signals). The cable turned out to be fine but the external speaker stopped working. I opened it up again and adjusted some parts and it just got worse. the HD2 didn't power on at all. I tried fixing it but to no avail. I ended up sending the HD2 to a repair shop and was charged $170 for the repair. the repair guy said i messed up the power IC and the connector for the external speaker and he had to replace the power IC and resolder the connector.
I think I'm gonna stop trying to open up expensive phones. i was stupid thinking that since I have successfully replaced digitizer for my previous Palm T3, E2 and T5, opening up HD2 wouldn't be a problem. Should have known HD2 components are really fragile...

How to remove "moisture under screen"

Hi all,
I had a big spot (3'') at the middle of my tab. It seems it is related to case warping and NOT related to temperature, etc. What I am describing worked for me and my tab now has a perfect screen (this is the 7th day).
I solved it by doing the following:
1) put the tab on a flat table. The screen should face upwards.
2) with two fingers push down at the top left and top right corner at the same time. You should try to "bend" the top corners towards the table. This will pull the screen away from the digitiser.
While you do this you should see the spot shrinking. If it does put some more pressure until it completely disappears. Don't put too much pressure to break anything
If, while you push, the spot doesn't shrink then stop and try the bottom left/right, perhaps your tab is bent there...
Hope it helps.
DISC:
I am describing here what worked for me... it might not work for everyone... don't blame me if it doesn't work or if it makes the situation worse.
Putting in the fridge less than 10 minutes works for me
Sending mine back to Samsung to have the LCD replaced worked for me. It's obviously a flaw in the design and the rush to get it to market without thoroughly testing it is the root of the problem.
Why on earth would you try to fix something like this yourself? You won't fix it, and its likely you will make it worse (battery damage etc)
This is why manufacturer gives you warranty, with gtab you have 2 yrs of it... I just send it few weeks without won't kill you but at least you will have fully functional device...
Sent from my GT-P7510 using xda premium
Mmmm Sure this helps?
I'm kinda scratching my head over all these fridge repairs for the Newton's rings problems. There shouldn't be a single 10.1 Tab anywhere on the planet that isn't in warranty. Just get it repaired/replaced.
None of the published fixes worked for mine anyway. Tried refrigerator, freezer, blowing, pushing, twisting, etc.
Verizon is replacing it. Just get it fixed right.
My biggest concern is the couple of reports of folks getting it back from Samsung and having the exact same problem reappear after 2 months. I am not sure anyone has conclusively confirmed an "improved" screen being installed during warranty service.
Could indicate the hardware is just fatally flawed for being subjected to heat >80F and any kind of pressure on the screen.
Keeping my fingers crossed that I get mine back with some sort of new and improved screen.
Works Like Charm
Tried this myself and it worked perfect!!! Thanks so much!!!

[Q] Dust underneath camera lens

Hello.
I've been having some problems with my Galaxy S II recently.
When taking a few pictures, I noticed that there are several black spots that won't disappear. I've attached a picture to help you visualize.
Honestly, I didn't expect the phone's camera to be this horriffic. I've got both a big red spot that's clearly visible on every single photo that I take and several dots that just cannot be unseen.
Having done some research, I found out that there is as of now no way to fix the red-spot problem, as it is caused by some phones' hardware.
I have also used the search function and Google to find information about the black spots I'm also having problems with. Turns out the only way to get rid of them seems to be taking the phone to a professional, in my case T-Mobile.
Having rooted the phone to gain full access, I'd have to get a JIG stick (not a problem, a friend of mine has one) and reset the flash counter. Then I'd have to send my phone to them and wait several weeks for them to fix/replace it.
Unfortunately, I haven't been able to find another possibility. Is there a way for me to get the what I suppose is dust out of the area beneath the lense? Should I try using compressed air to blow it out?
And if I sent it to my provider and they replaced it, is there a chance of me getting a I9100G instead?
Tl;dr Is there a way to get the dust which causes the artifacts shown in the picture out of underneath the camera's lense that doesn't involve sending the phone to a professional and hope that they'll be able to fix it?
Thanks in advance!

I'd recommend no self-medication,you should un-root it and send it to T-Mobile. It's better that the professionals work on it rather than us. But if you still think you can do it then jsut open your phone with a screw driver? and clean it?
I have the same issue, one day on a boat tour in NY the camera suddenly got spotted with black dots. No warranty so I bought a eyeware repair kit and took it apart and cleaned thoroughly. No improvement. Dropped it in a toilet by accident 3 months later, took everything apart, cleaned more, left it in a bag of rice = still black spots. But its working nonetheless. I'm putting a case on my next phone.
I also noticed a big black spot on mine.
Cleaning lens, nope. Tapping on the back where the camera is, nope.
So I took the back off which was easy. Make sure you remove your sd and sim!!!!!
Take out the screws and use your nail to open. Start prying the back off. It will look and feel like a no go in the beginning but all of a sudden your nails will slide in between and you can work your way around to get it off. I recommend you start at about 2cm or like an inch above the bottom of the device and then go to the bottom corner. The volume and on/off buttons might fall out but no worries, easy to stick m back in.
I took a look at the inside of the cover but nothing that could cause a black spot.
Now when the back is off you can still attach the batt, just make sure you don't make sudden moves as it is not locked in. Also you do not need the sd and sim in to test.
Start it up by gently pressing the power switch with your nail. It boots up like that.
Now start the camera and you will see the spot(s). I would give it a bit of a blow, don't spit . If it is not moving or going away, like in my case, start tapping with your nail on the lens (no harm done). If you tap with the backcover still on you don't actually tap directly on the lens so there is almost no effect. In my case I could see the spot move. I tapped untill the spot was gone.
There was no 'void' sticker on mine and it took me like 10 minutes so if you feel adventurous I would give that a go.

[Hardware] Galaxy S3 display no power

Hi there,
my girlfriend smashed her Galaxy S3 sometimes. Now it's done, the glass is broken in the upper left corner. The screen worked fine. A few days later she dropped it and dropped it again... i think she needs some wooden sticks to make a bushfire to call her friends. After some drops the screen stopped working fine. The screen turns black and if i push the upper left side a bit, the screen apears... very purple. I watched some tutorials about replacing the glass'. So i opend the galaxy s3 checked the ribboncables and after reasembling the screen won't start anymore. The softkeys doesn't apears. The phone is booting and make sounds. That means, power is there but no power for the display. I only want to now if the display is okay or not, to buy a new glass. But now i have these power problem. Somebody know how i can fix it? Or do i need a new display with digitizer? It's not cheap... a glass is much ceaper .

Multiple posts on the subject including a you tube video on replacing .You need to search them and decide .

Not sure how that happened...
Thanks in advance for looking.
Ordered a screen replacement for my wife's busted S3 screen. Got it, followed directions....got the area around the headphone jack a little too warm, but continued and finished removing the screen. Once I had the screen off, I thought it would be a good idea to power it up to make sure everything was working, especially the top left corner of the screen that was closest to the over heated spot.
To my skeptical surprise everything was cool. Took a picture, looked at some higher res pictures....just to make sure everything seemed normal, to which it did. Powered down, removed the battery and the SIM card and continued on.
I cleaned the screen with alcohol as the directions stated, put everything back together..and NOTHING. The thing is bricked. Any ideas how? I wasn't doing anything remotely related/close to the ROM. The only difficulty I had with any part of this (aside from the aforementioned over heating) was with the two ribbon buttons at the bottom, which got slightly tangled in the tape.
Before I attempt to 'unbrick' this does anyone have any other ideas? Battery is good, phone has been plugged/unplugged while attempting to power up....I didn't take anything else apart so I can't think of anything else that would have goofed up this phone.
If your LCD was broken a new bit of glass wouldn't fix it. It's almost impossible to change just the glass without damaging the digitizer. Most alcohol will destroy an LCD so cleaning it with that is a terrible idea. If you plug your phone into a computer see if it connects, that will at least tell you that the phone is still working, just broken display.

Awesome. Per the instructions: "clean screen with Isopropyl alcohol to remove any excess glue"
Plugged in or otherwise, I get no LEDs, vibrations....nothing. Wondering if a jtag would even be worth it?

[Q] Issues after replacing glass: Black out and self typing during calls

Hello all, and XDA developers,
I'm a short time lurker, and flasher, but that's besides the point. I've started my own business repairing phones and I've gotten very good at it, I have extremely fair prices, and this is putting me through college.
I've ran into an issue and I can't figure it out. I try to stay up to date on phones since my job requires that I work on phones, and although I couldn't find all the information about the hardware under the screen of the SGS4 i decided to replace a broken glass screen any way..... well now I have a dissatisfied customer on my hands and i'm doing everything in my power to rectify the situation.
What I did:
I used a heat gun to lightly heat the screen of my customers broken phone, like I have done many times before with other models of phones. I scraped off the old glass, cleaned the glue out thoroughly with alcohol and a small piece of microfiber (like for cleaning screens and glasses). I laid down 3m tape (possibly in the wrong place). Put the new glass on, and PRESTO done.......
The result:
A beautiful new screen, but the wake up motion doesn't work any more (where you swipe your hand across the screen w/o actually touching it), and the screen automatically blacks out once a call is placed. This may be because of where i placed the tape, but a new issue has reared it's ugly head...... It's typing now... by itself.... during calls and at other times. She wanted a different color for the screen and i told her that I will replace the screen and fix the issues all in one motion, but I'm not sure what is making it type on its own. Does anyone have any clue as to what could be causing this issue? I have until the afternoon of 9/25 Central time (UTC-06:00)
Thank you to everyone for existing, this forum, even if it doesn't resolve this issue, is simply a work of art by mad geniuses from all over the planet. I love everyone of you.
