Don't know if anyone else is experiencing this with their Play but as of a week or two ago the backlight started acting strange. The backlight will randomly stay off when I push the power button with the slider gamepad closed. Only way to make it come on is to pop out the slider. It seems to be random, and if I push on the slider edge slightly with my thumb with the slider closed the backlight randomly flickers, ranging from slight to severe.
The display is still working despite the backlight issues, I can open apps, and use the phone normally but the backlight flickers on and off. Makes it especially hard to use the phone in the dark.
Phone has never been dropped once.
I've replicated this problem with a variety of roms, both custom and stock. It's definitely not app related or even custom kernel related. It happens on a fresh wipe with stock rom with stock kernel. It happens on CM7 with custom kernel.
I'm curious if anybody else is experiencing this. It would tell me if it's just an isolated incident or if others are having this problem.
Sounds like a faulty connection to the backlight to me.
I had the same problem 2 days ago. Then I couldn't get my phone screen on at all!
I sent my phone back to Sony, even thought I bought it second hand. Phoned them up and talked to them. They asked what time of year I bought it so I said around August and then they gave me the address to send it to. Now I'm just waiting to see what happens next.
If your going to send your phone to Sony for repair then make sure you put the fresh firmware back on and un-root your phone as that breaks the warranty (unless they don't know about it)
Hope I helped you. If I did then click the thanks button
Sounds like a faulty ribbon cable to me. (cable that connects the screen to the rest of the phone)
You wouldn't need to drop it for that to go bad, It could just be a case of opening and closing the gamepad or lot.
Yeah good thoughts, most likely the ribbon. That really sucks because I've only had the phone for 7 months, and I've taken excellent care of it. Sounds like a major design oversight.
Mine is probably near complete failure at this point. It's taking a lot more effort to keep the screen on now. Fearing soon it won't work at all.
In hopes that this might help someone else down the line, I was able to fix my problem. Yesterday the screen pretty much quit and I had no choice but to try and solve it myself or buy a new phone.
Using this disassembly video as a visual aid I carefully pulled my phone apart: http://www.youtube.com/watch?v=-3n5ZfkqhzE
You'll need a torx T5 tool to pull out all the screws but they are cheap.
Underneath the phone and jammed into the screen ribbon was a rather thick hair just hanging out. Somehow it buried itself in there. I removed it, unplugged and replugged the screen ribbon and cleaned the dusty inside with a q-tip and reassembled it all together.
It works fine now, so hopefully this helps someone else avoid having to pony up for a new phone. For those under warranty probably best to send back but for those like me with no warranty it's worth the shot.
So lately I've been having problems with my DI2. Occasionally, when I unlock, it appears to receive what it thinks is a touch at a lower portion, usually around the middle of the lower portion, of the screen, and this results in things like Home being activated, or the app drawer. This will happen even if no part of my hand is near the bottom of the phone (front, back, and sides).
More recently, it has become and indication of random touching on lower parts of the screen. I've had it completely freak out and type random stuff in input fields. When it gets really bad, the touchscreen stops responding, but I can lock and unlock to get it back, usually.
This has made typing in portrait mode quite difficult, and it's becoming very annoying.
Is my touchscreen digitizer failing, or is it possible there's some sensitivity adjustment I can make? Is it possible it's related to static or something and I can use a cleaning solution or something to correct it?
I really want to avoid paying a lot to fix this issue. I've already seen places where I can buy a replacement digitizer if that is needed, but it's not cheap. I'm really hoping this phone will hold out a lot longer than it is right now as it's been an otherwise good phone.
You may want to try recalibrating your screen.
Go to Settings > Language & keyboard > Touch Input > Text input > Calibration tool.

i think this only calibrates the keyboard. there is an .apk around somewhere that will calibrate the touch screen, some roms have it built into the settings.

Well, I'm not having much hope with calibration apps. This looks like a very device specific thing, which is understandable. Besides, it doesn't really feel like a calibration issue. When it's not going haywire, touch accuracy seems fine.
I'm not really keen on going for a replacement. Besides, my physical modifications (antenna improvement, improved access to power button, etc) may prevent that
If I can't find a cheap/free solution, I'll just jump on replacing the digitizer. This is not a task that bothers me, was just hoping someone came across this issue and found a better solution.
Harbor Freight has the hot air blower for $12.00.
This may be a dumb question but i didn't see you mention it. Did you try a factory reset? Perhaps you have an app or something conflicting with screen response somewhere in there.

I seem to have dead spots once in a while on my touchscreen. Doesnt really effect day to day usage but can be annoying when trying to click something. Like a link on a webpage, sometimes I will have to scroll up or down to move the link before Im able to click it.. spot seems to be centrally located but has happened in a few places.

Not a dumb question at all. I did not mention it, and it's completely valid. However, I have gone through a couple of full resets since the issue started, and the behavior has persisted.
In fact, I have tried a couple of different firmwares in the time it has started. I had thought maybe a build of CM7 might have caused it, but the ICS builds have the same behavior, as well as a couple other firmwares that I don't remember the name of offhand.

For me, it's not an issue with dead spots. For one thing, the issue is intermittent and in varying degrees of severity. Usually when it happens it's just something at the bottom activates and I can cancel it out and carry on with my session. Occasionally, though, it just goes haywire, as though a palm is resting on it or something is touching random places rapidly.
So far I've been able to kill the haywire behavior by locking the display, wiping it down a bit, unlocking the display, then continuing on. I haven't had to take any more drastic measures than that. It's still annoying in that it can happen while typing a message and I have to go back and clean up the mess it leaves, or it might monkey around with an app.
It seems as though there might be some static buildup or something because it seems worst shortly after taking it out of my pocket. If that's the case, I wonder if I can ground it out, or do something to dissipate it.

Sorry i didn't notice you mention it anywhere. Fwiw i get lockscreen issues kinda like you describe. i use the slide lock on cm7 and when i go to slide right to unlock, before it gets to the dot the lock releases without me lifting my finger. I know i don't have a dead spot because it only does it on the lockscreen and relocking and waking the screen fixes it. Only happens on cm7 and why i thought it might be an issue like that.

If you need to replace the screen/digitizer you will need to heat up the glue to remove the screen. Normally a heat gun is recommended

Bro I just went thru the same thing same week. And I've tried all the suggestion here, in the end it was the digitizer. I call Verizon and explain the problem and they are sending me another Dinc2. It sucks cause now you have to unroot and restore (s on) (which for me was a bit of a *****) to send the phone back , but trust me at some point the entire bottom part of your screen will not respond to touch.. You'll only be able the answer calls from the lock screen and to hang up you'll have to do so thru the pulldown bar. And the biggest problem will be you won't be able to access your key pad. Sorry bro but thoses are the facts....I'm waiting for the replacement as I type this.

It's not held in with a normal ribbon cable lock? It would be strange if they used a glue. I've been inside many of these devices in the past going back some 10 years (including at a repair center) and didn't face glued ribbon cables (either solder or ribbon cable lock).

They are held in with a ribbon cable lock but the screen and digitizer are glued onto the phone itself, like the metal part that holds all the parts
So I wasn't able to find a software solution. Not sure what's causing it, but it's causing some unwanted issues (hang up call and it immediately calls someone else based on a false touch). I ordered the parts I need and will report if this fixes my problems.

Where did you order from, how much did you pay?
Be sure to watch both of those vids on utube.
I live where the relative humidity is around 15% most of the time.
Still I notice that when I pull my phone out of my pocket, it has moisture all over the back where it was pressing against my leg.
I found putting it in a soft cover pouch keeps most of that under control.
Just for the heck of it , try putting the phone in a jar of un cooked rice for a few hrs.
Battery and cards removed, jar sealed tight.
If you have another phone to transfer your calls to that would be better.
If you are like me and your skin oil transfers to your phone allot, use a fine tooth brush around the area where the screen meets the housing.
Avoid pushing any debris further into the unit. Use brisk outward strokes.
If none of that produces any favorable results, look for a hot air gun or a blow dryer.
Keep us updated...

I've worked in microelectronics in the past and know quite a bit about moisture control, static control, etc. I had to help manage a sizable clean room at one point.
Unfortunately it's possible that my digitizer is just flawed and the flaws are just now coming out. I don't think it's moisture, but rather most likely electrostatic. I live in a rather dry place.
I normally would not use a screen protector, but I might consider it now as it might add an extra layer of insulation from static in my pocket.
The digitizer I found was from a seller on Amazon. For all of the parts needed (I don't have the tools for properly working on this device), including the small double sided tape, I spent around $32.
The double sided tape comes in a big roll so if anyone else needs to do this kind of repair, I will ship the remaining tape for the cost of shipping (this should save you about $5).
Hi,
I have had my HOX for 3 weeks now and since yesterday (so, not a new thing), I keep losing the signal in my appartment, in some places outside. Oddly enough, signal is OK (tho just 3-4 bars) in my office.
1. Could this be related to the WIFI antenna issue even tho it's not WIFI issue? In other words, is there a chance that by fixing the WIFI antenna issue, I can get solve this?
2. If not, what are my other options? The garanty is already voided so I cannot send it to HTC for repair (voided by an "unofficial repair center" after the screen got smashed by dropping it from like 1m... - it's very possible that the fall or their repair broke something else, but the repair was already 2 weeks ago)
Thanks for your help!
First thing I'd ask is are you rooted? Have you been playing with radios recently?
If not, the next thing I'd look at is trying to find someone else with a micro-sim, and asking to borrow it. If they still get a good signal on their network on your phone, it might be your sim card. I had a faulty one once which just started dropping network like you describe. It can happen.
If their sim card also shows poor reception, you might have an aerial issue caused by the unofficial repair centre opening the phone up. (Although from the feedback on the WiFi issue thread HTC have worrying repair standards too).
If you can't find another micro-sim, just try finding someone on the same network. This phone (when working) has excellent network reception (better than my previous Desire S) so if a side-by-side comparison shows a big difference in signal strength, again I'd think about getting the sim replaced.

If your replacement sim still has the same problem, then I'd consider opening the phone up as per the video guide in the WiFi Issue thread in the general section. Seems to be quite easy if you are careful. It is unlikely that the same aerial for the WiFi is also the 3G one, but I've looked at the tear down pictures, and can't read chinese! If i find out which one it is, I'll update this post. If not, just check all the connections.
Hi,
I have also been having this network drop issue but only near my office. The reason I think is that my office is between two towers and every now and then it tries to balance the traffic on the networks and hence keeps disconnecting devices from one to connect to the other one... However, I have cut out my normal sim into a micro sim and that was done by the guys at the shop from where I bought the device and they had said that if there are any issues, then please order a proper micro sim and use it....
I think that might also be the problem.....

All,
After checking that my SIM card wasn't in cause (used a friend's HTC One X to test my SIM card and test with his), I broke open the case and saw the problem.
The problem is the damn design of those antenna contact! I saw probably around 10 of those small metal piece that are supposed to be a bit "up" and somehow touch the contact area on the back cover.
I found that 2 of them (in two different pairs, they all seem to be in pair to create a closed circuit I suppose) were a little bit lower than their counterpart, so with a flat screwdriver, put them upright, closed the case and voila, I am enjoying network with full bars since yesterday.
If the issue comes back (and it probabl will, if they got bent the first time it probably means that the metal already was bent beyond its elastic deformation area), I'll probably end up buying a soldering iron a add some patch of silver to increase the height of the contact zones. That's .... just lame I am sure they had a good reason to do that, but seriously!?
Guillaume
Glad you got to the bottom of it. Yeah I think the design choice is forced from having the main body of the phone slide in at an angle into the outer case. If the two parts just clamped together like a more traditional phone build, then they perhaps could have used a different approach.
I'm putting off opening mine up (I have the dreaded WiFi drop issue) as my current case puts just enough pressure on the screen to act like a permanent squeeze, halting my problem.
Would be interested to know if the problem reoccurs like you said it might. Keep us posted.
Hey guys, like many Toro owners, I had my MicroUSB port finally go out on me. Followed unfortunately shortly after a tumble caused by a cousin just giving my phone to her 3 year old to play with at a family holiday party. This resulted in the screen being cracked all to hell, as one could imagine. In a stupidly rushed attempt to repair the screen glass with a spare piece I had from a friend, I messed up the digitizer, and decided to get a new screen assembly and start over. Unfortunately, after ordering both parts and starting to install both, I realized the mUSB board was no good and had to be exchanged. I slapped the old one back on, installed my screen, and went about my day.
The second time around, I actually remembered how to work on computers and went through my whole usual litany of prep and breakdown. Bled off all my static charge, made a mostly sterile work area, worked in gloves when I could, and proceeded slowly and carefully through the phone teardown. I made sure (to attempt) not to damage any ribbon connectors or even the LTE antenna coax cable and both ports for it.
All this only to notice a short time later that I was having poor call quality, call drops despite a couple of bars, random signal drops, all those good times. This was all with mobile data turned off entirely, but when I turned on mobile data, it hit straight to 4G full service and data was snappy and page loads/searches were fast. However, I cannot tell if it is area signal strength or phone error, but I'm inclined to believe I may have messed something up either in my first botch job, or in my second serious repair.
If there was any repair errors, I'm inclined to believe one of a few things happened. Either I screwed up one of the in-frame antennas the first time around, putzing about trying to pry the old screen off the frame. Or I somehow cocked up one of the CDMA antennas on the mobo itself the second time, but I find that very hard to believe. Or the old mUSB board with it's mic got screwed up, but I highly doubt that too.
Anyone have any ideas, further questions, or (preferably non) snide comments? I've tried to give as many details as possible in this post without overloading it, but let me know if I've left out anything useful. Yet again, it's a Toro, 32gb, running SlimKat's 4.4-1825 weekly. (Can't remember build date right now, and phone's in pieces again for visual verification/pictures)
Any help is greatly appreciated, and thanks!
I thought this was worth sharing, this is my second thread ever on XDA and hope it helps somebody.
Quick story about my case:
I tried software fixes, ROMs, and made a lot of reading, when I finally figured it could be an antenna issue, I decided to give myself a try on my cellphone repair skills, turns out I turned a “nearly dead” GPS taking 10 minutes to lock into a “better than average” GPS taking 20 seconds to lock. Time taken for the task, 15 minutes, time suffering from bad GPS signal, 1 year, go figure.
Let’s see if you are a candidate to try this solution:
- You must be sure this isn’t a software related issue (i.e. my GPS works with X rom but it doesn’t with Y rom, that would certainly be a software issue).
- You CAN get a GPS lock but the signal is weak (i.e. constantly dropping signal in an area where you are sure another phone works fine) or GPS locks takes up to 5 minutes (and you already tried a software fix to speed up GPS lock).
- You’re phone is relatively old (i.e. it was bought when it came out, although I’m sure the quantity is low, I assume there are still E98X phones which are brand new and I would not recommend disassembling a brand new phone).
- You have experience opening cellphones (i.e. experience using small phillips screwdriver, gently popping frames/housing/covers, putting back in position plastic buttons before re-assebly).
Before we start, quick explanation on what may be happening to your phone if you are a candidate:
- Presumably, the GPS antenna (and Bluetooth, 3G/4G as well) is making poor contact with the springs on your phone.
- This phone uses contact springs for pretty much everything (see attached picture for springs locations of antennas), so these springs and/or the antenna contacts eventually bent away from each other and lower your GPS, Bluetooth, 3G/4G signals.
Here is what you need to do:
- Remove the back cover, and remove the back frame (See the following video from minute 0:00 to 1:50 for disassembly of backframe https://www.youtube.com/watch?v=S9OJRtf39QA).
- Inspect every spring and antenna contacts (see attached pictures for antenna springs and pad locations), make sure they are not rusted or damaged, else you need a replacement part for it (for antenna pads, you may want to clean those with isopropyl alcohol if you have some).
- Using a soft, thin, *plastic* tool (thinner than a credit card, but sturdier than paper), lift every spring you see up to 10 degrees (see attached picture for reference) and wiggle it up and down to force it to stay tilted up about 10 degrees (don’t force it up more than 15 degrees when wiggling or you risk to break the spring, there are quite a few of springs, I remember at least 5 pairs, so make sure you get them all done).
- Revert all disassembly made (See the following video from minute 6:32 to 7:51 for reassembly https://www.youtube.com/watch?v=9QxLa5rXX7Y), and VOILA!! your GPS signal came to life again (and hopefully your Bluetooth and 3G/4G are enjoying the new perks too!)
-Additionally, better 3G/4G signal does save battery, your cellphone amplifiers require less work and produces less heating too.

I was looking for something like this. Thanks very much..........
Let me know if you need anything else (i.e. more detailed instructions) and report back your results, unfortunately for the audience, I didn't take pictures of the process since I wasn't sure it was going to work (and then just took the picture of the NFC springs), so if you can take some pictures of how the contacts looks in the inside, that would awesome, I can update the main post with these, there is quite a few springs inside so you want to make sure you get them all in shape.
I forgot to say in the main post, better 3G/4G signals give a lot less of work to the amplifiers, which means less phone heating and less battery consumption, this is a nice service to do to a 2 year old phone like mine.
Enclosed is a picture from a replacement mid frame cover. Could you please use something like ms paint to circle which pins you bent upward? Looking at my Optimus G Pro 980 Mid frame cover and motherboard/logicboard I do not see these........

UPDATE:
See main post, I got a picture from somewhere else for the spring locations.
Actually my friend, that picture only shows the pads for the antennas, try to match it with your phone and see where they contact, these are going to be the springs, they don't look like spiral springs, these are other type of springs which I don't recall the name but they are more like a V shape, and one of the sides is attached to the board and the other one "springs" up and down, let me know if you got it or I will open my phone again, just for you! (no kidding)
Also, if I were you I would try to do the same for all pairs of springs I see on the motherboard, there is a pair for the speakerphone and one more down the board for something else.
GPS finally fixing
Thank you so much for this post. Before this solution, I tried different roms, gps fixing apps, disabling carrierIQ, editing the gps.conf file to add "better" servers, etc. This is the only solution that really worked. Now I am getting a GPS fix in 10 to 15 seconds where before it was up to a minute or more. I have an LG E980 (ATT Version).
As directed, I turned off the phone, removed the rear case back, removed the battery+sd card+sim card, removed the screws in the back panel of the phone and then separated the back panel from the front panel to expose the circuit boards and spring contacts. Then, I cleaned all the spring contacts and their mating flat contacts on the back panel with alcohol. Then I bent all of the spring contacts up slightly, re-seated the back panel making sure the side buttons were in the correct place (I do not believe the quickmemo and power buttons are interchangeable even though they are the same size fyi), and then secured the screws back in place.
Thank you!
Way to go buddy, I'm glad I could help you and that you were able to follow those horrendous instructions, I can't be sure on your case since yours wasn't as bad as mine, but on my case it also improved 4G reception overall, these antennas are used for pretty much everything so it would only be logical to get better signal on all the services, this is a "must" service on old E98X phones, perhaps nearly half of the GPS and bluetooth issues on the forum are due to this plus a weak or faulty software filtering not helping.
any info how to increase the wifi antenna? could this be the white cable?
Sent from my LG-E980 using XDA Free mobile app
I've quit using my OG Pro because the GPS is so poor. Hard to get a fix and drops constantly. Glad I stumbled on this, and will give it a try.
Can you point out which springs are specific to the GPS antenna? I suppose I can try to work with all the springs, but with my luck, I 'll break something that was working fine.

I don't know which ones they are. I did all of them. They are a lever type spring contact so it is hard to break them. Just do so lightly.
Wow fairly simple fix with great results, thanks!

Just tightening all the screws fixed all my GPS issues. No disassembly required! Add this into OP.
Thanks
Just did this, really improved the speed and reliability of everything- gps, wifi, etc. Thanks.
A quick tip for those doing this the first time. be careful of the buttons. I've taken apart my optimus g pro a few times now, and those dern things like to fly out of you're not careful when taking it apart. Also, when putting back together, use a small piece of scotch tape on the exterior of the frame to hold the buttons in place when you put the frame back in place. make sure the tabs of the tape stay on the outside, and pul them gently as you snap the screen back on. It's easier to have the frame on the table on put the screen down onto the frame when done this way, and save those dern buttons from coming out of their slots.
I have two OG Pro (E980) developed same broken GPS issue.
Now, I think the problem is the two soft contact pads, when I bent little bit, the GPS 's issue got fixed.
Also, the method not to improve any 4g/Wi-Fi/Bluetooth.
LG made such low quality contact PINs
Two years have passed and this thread is still helping people with their now "ancient" G Pros. My problem was that the coax cable had popped loose. Still I went ahead and re-tensioned all the contact springs. GPS is now functioning like new. Thanks to all who contributed.
