I recently had the pleasure of looking at my Photon Q to find a mess of cracks in what had previously been a pristine display. I have no idea how it happened, since the phone had been in my pocket for about ten minutes while I was shopping and it definitely wasn't cracked before that. My only guess is that I bumped into something while I was shopping. I'm guessing this detail is irrelevant, but I'm including it in case it's of-interest.
I've done replacement surgery on phones before, and I was in no mood to do it again so I took it to a local shop. They managed to replace it, but when it came back from the shop it was stuck in landscape mode. I checked out the accelerometer with Z-DeviceTest and it seems to be just fine. It seems like the logical culprit is that the phone always thinks the slider keyboard is open, even when it's not. I don't know how to test for this, though, and I haven't been able to find a Google search incantation that tells me anything of interest.
So my questions are: Does my diagnosis seem plausible? How does the Photon Q detect when they keyboard is open or closed? Is this something that probably got borked in the process of disassembly/reassembly? The phone is going back to the repair guy shortly because he also broke the earpiece speaker and he needs to replace it (at no charge, of course), and I demonstrated the won't-do-portrait-mode problem to him before I left the shop. Is there something along the line of "make sure that you screw the flibbertywidget into the whoozamawhatzit" information that I can give him?
Thanks in advance!

Nah, when the keyboard is recognised as open, auto-rotate won't work.
A possible workaround is to use a terminal command to simulate keyboard open/close, but I'm not sire if it would work. I'll post the command later.

Thanks, both of you. I've confirmed my diagnosis, I think-- I've noticed that the keyboard backlight stays on even when the keyboard is closed.
Think that's normal, I us backlight off app to turn it off.
If you paid good money to get your phone fixed, may take it back and make them do it right?

In adb shell:
Code:
dumpsys window | grep mLidState
mLidState=1 means that hw keyboard is out (at least the lid sensor says so)
mLidState=0 hw keyboard is hidden

That's certainly not normal, keyboard backlight is automatically turned off when the keyboard is hidden.

test magnet sensor...

Solution
This problem is caused by a small magnet being removed during repair. The magnet isn't held in place by screws or tape or anything, it just sits in a small open space between the sliding keyboard tray and the LCD display layers of the phone. The location of the magnet is on the right side of the phone if you are looking at it up-right and about an inch below the volume buttons. Without this magnet the phone thinks the keyboard is out the entire time and the screen won't rotate. Replacing the magnet requires nearly complete disassembly. I've found you can save several minutes and a headache by taking the phone apart until you get to the sliding keyboard tray and taking off the 6 or so screws on the right side, then lifting the right side several millimeters and popping the magnet in from there. This way you won't have to take off the touch screen digitizer and other fragile ribbon cables. Once the sliding keyboard tray is re-attached with screws the magnet can't go anywhere. Good Luck.

Having problems with the touch screen on my sensation and this has now happened on my secound phone! both phones were ok out of box but after a few days first noticed problems from lockscreen as phone would not always unlock when draging app icon into circle then slowly geting worse until would take several swips on screen to even unlock! then started noticing similar problems in norm opperation? sometimes works ok but some times freezes up have tried factory reset and no differance. very strange having this problem on two phones?
Does the touch screen stop working completely?
Mine did that on Monday, had to get a replacement.
it seams to stutter once awake works slightly better? but still not responsive
I've noticed that the proximity sensor and gyroscope are being used aggressively to filter accidental screen presses.
For example, if I place my sensation flat on a table, the lock screen is very hard to unlock. If i place my other hand near the proximity sensor at the same time (or tilt the phone towards me) it unlocks easily. Until I identified this functionality I was beginning to think my right index finger was unsuitable for touch screens (since when placed on a table I tend to use my right hand, but otherwise use my left to unlock).
Hopefully this will be tweaked with future updates.

Many thanks I hope itd that simple?
I am having the exact same problem, for example on the lock screen I would swipe up but the ring will move slightly, and one icon I.e the camera icon will move towards the ring, another grip which is buggin me is that it will miss screen taps, I.e when texting or clicking an icon one tap will go unnoticed by the device resulting in either a missed letter, or the app not opening. This also goes for the 4 command buttons at the bottom, it happens on these too. I also get the occasional lock up.
Factory reset did not work

As I stated before, I experience this problem but it only occurs when the phone is laid flat and my hands are well away from the proximity sensor at the top left of the screen. I can say that the part you are describing with the lock screen is 100% the same problem I come across in certain situations.
Please test to see if the problem is still present when the phone is tilted in your hand and, if you are laying the phone flat when you experience the problem, try putting your other hand near the proximity sensor when you try to unlock.
If this happens as I describe then it is most likely a software bug which only affects users who have particular phone use habits.
Saying that, as you are having quite severe symptoms, during general use, it may be that you have a faulty proximity sensor in your phone - leading to missed screen taps when the phone thinks you are not touching the phone.
Well I laid the phone flat and unlocked it no less than 20 times, each worked flawlessly no problems at all..... Seems to have me baffled
Yes I've been having the same problem. First noticed it when trying to unlock it (phone was lying down), couldn't get the circle to move. Have had one complete touch-freeze. No input possible, however volume and power button worked. Took the battery out, restarted, and it worked fine.
I notice that input can be difficult sometimes, hit and miss or just have to push harder. Strange. Seems like a software issue to me.
edit: just had the same issue - circle wouldn't move. After picking the phone up I was able to unlock it, however still not as easy as it should be, a bit jerky.
Both my evo and my g2 had a grounding issue, for example if I had the phone laying down on the couch or bed, the screen would not respond to touch but if touch the phone with a finger and try to unlock it with my other hand it would work normally. So it seems to be a common problem with some HTC devices

The wildfire (my friend's got one) has this problem too. You have to keep touching the metallic housing for it to detect any taps.
You are correct, aim1126. I never considered grounding to be the cause but after re-testing it clearly is.
I guess it is a side effect of having a conductive unibody. So basically there will be no software fix, we just have to keep constant contact between our hands and the unibody. I wonder whether a rubber bumper would actually make this problem worse?
Edit:
Actually, the screen seems to adapt to not being grounded properly after a couple of presses. It works fine for me by the third time I touch the screen - weird. Well at least it is only a minor annoyance!

My wife uses a G2 and I wouldnt call it a grounding "issue" honestly seems like more of a feature to make sure you ment to engage the screen.. Its kinda cool IMO
As far as the screen being laggy this sucks since I wanted to upgrade from my Vibrant to the Sensation.. I also am not sure its a software issue you guys are having.. I am running Sense 3.0 with gingerbread on the G2 and it is very smooth.. The option to silence a call or tirning on speaker phone by turning the phone over is neeto torpedo..
I'm having the same issue, from lock screen I drag the circle up and it just stutters. After a few tries it usually works, once unlocked the touch screen appears to work fine. I'd expect the issue would continue after unlock if it was a hardware issue.

That's very bad. Flaky lock screen is not good, and the example of not being able to scroll through apps without it running one is a killer. There are many times when scrolling through a list of selectable items is necessary.
Are you going to exchange the phone?
Have my hopes set on the Sensation, so would really like to find out what the resolution is.

EDIT: Alright, I did the reset completely now and it seems to be working, still kinda reluctant to work in portrait mode. Suggestions/comments/help highly appreciated.
Hi, I've lurked this site for years but I only joined just to ask this question.
Now, I currently have this phone, the Mytouch 4G Slide for T-Mobile, for about 8 or 9 months now. Everything is fine. Except when I dropped it.
I dropped it and now the touchscreen sometimes doesn't work, no matter if it's in portrait or landscape. The keyboard still works and the face buttons work but the touchscreen is iffy. I thought it might be the digitizer but after doing some research on Google, if it were that, it would NEVER work from what I understood.
So, from then I thought it had to be a software issue, which is understandable as I did install a bunch of apps within the month, one of those including a compass. I removed and saved everything, then did a master reset/clean wipe and restarted my phone anew. I turned it on, and the screen came on. I went to slide the ring, and it didn't slide. Everything else works, touchscreen is still being pissy.
I notice when I let it sit for a bit, with it off and with the battery out, and turn it back on after about 5 to 10 minutes, it works okay. Either the screen will work in both portrait or landscape, OR only portrait or landscape. And sometimes, rarely, neither will work.
Is it possible for the digitizer to be -slightly- damaged? Or is it one of those things where if it's broken, it's noticeably broken? I'm not sure how to go about this as I've done everything I could think of. Some assistance would really be nice.
Digitizers can be partialy working, I have ran into this many times. To me it sounds like a bad digitizer or flex cable, but more than likely the digitizer

So, should I open it up and see what's going on or just replace it completely? I already know how to, I just have to go and buy the kit.
I have torn open many phones in my day, and this is without a doubt the most pain in the ass! If it won't cost you much to have someone else do it, say less than 50, it may be worth it. But it will only be 20 if you buy a new digitizer from ebay and do it yourself. Its easy to tear apart untill you get to the "screen assembly" for lack of better words.
Here there is soooo much sticky it can be hard to take apart without cracking lcd. So if you do this, use ample heat for like five min or more to seperate the chasis from the lcd back.
If your curious on my expeience I posted about it here

After having a duff sd slot on my original surface my replacement arrived today, all good, left it doing updates and installing my apps for a while, all was well, or so I thought..
The keyboard is now not responding after a while, connected, works, close the cover, open it again, screen doesn't come on, press power button screen comes on, keyboard not responding, close cover, screen stays active, disconnect keyboard and reconnect it and it works again..
Had a quick look through the settings and there's nothing I can see that relates to keyboard sleep or power management..
Tried it on my old surface and its fine :\
Wondering if anyone has seen or heard anything similar, otherwise another tech chat with support tomorrow...
You might want to try rebooting the new Surface, and make sure the connection port where the cover links up is clean, but otherwise I don't know what would cause that problem. I've had cases where the cover wasn't recognized, but disconnecting and reconnecting it fixed that.
Only issue I ever have with the cover is if I remove it while the tablet is sleeping and when it wakes it thinks it is still attached.
It's been rebooted many times so dont think its that, had a poke thru device managet last night and looked for power saving stuff but nothing relavant..
Connectors are all clean and it works in the old Surface.. :/
Maybe the keyboards just missing the tablet it came with lol
Still nothing, hard reset, power offs nothing, have now noticed that the edges of the touch cover are peeling apart at the corners so might get this replaced as well, so far the support guys have been spot on, the device however while really promising just lacks finish :\

Two options....
1. Return the cover..
2. Bring your surface bad cover to Microsoft store and let them figure out what is wrong...

I've had 2 bad units now, don't think its the cover as it worked on the first surface before I returned it.
I'll get onto surface support when they are back, I don't seem to be able to raise a ticket on the new unit, touch cover might end up going back as well at this rate...

I've had the same issue with the type cover. Sometimes it works fine throughout. Other times it seems to fall asleep until an adjustment is made.
I've caught the connection off by a few millimeters at times (although that doesn't explain why the initial connection would work), but you can look and check for that as well.
From now on I'll simply restart from the Power button without removing the connection to see if it's really a 100% mechanical issue.
Ha I've had all of these problems you've named
On Live Chat with support now, the MS forums seem to suggest a reset, I've tried it a few times tho, will see if they will fire out another cover..
Right, cover is being swapped out on AR as well now, hope they hurry up and take the hold off the card though, the hold is for more than it would cost to actually buy the bloody thing new again..
Well this is weird. This morning I woke up and grabbed my G from next to my bed and the touch screen is being all slow and not responsive. I can't swipe left or right without doing it very slowly and deliberately. Same thing with bringing down my notification drawer.
Its making the phone near unusable. Even to type this all out I couldn't use Google keyboards swipe typing feature and have to hit each individual button really slowly.
Anyone know what could be causing this?

Install this and see how it behaves https://play.google.com/store/apps/details?id=multitouchpro.tests&hl=es
Thanks for that useful little app. It registers all my fingers fine, and its good if I swipe slowly, but if I swipe too fast it loses my finger for a second, which I guess is why I have a problem swiping.
I have no idea what's causing this still though since its been working fine for the past month.

Have you tried turning it off and on again?
Do you by any chance have the charger plugged in while doing this? (My nexus 4 screen acts that way when I connect the wall charger)

Same here, part of the screen is unresponsive, except if you move your finger very slowly.
I have the problem described by OP if I am charging with a high ampere charger. It is solved by me by turning the screen off and on after unplugging it.
I forgot to update. The problem just kind of fixed itself over a few hours. I took it to work and it was still having the problem, and then I took it out of my pocket a few hours into my shift to check a text and it was working like usual.
I dunno. Magic I guess.

Guy who did a waterproof test on the Moto G encountered the same issues you described. As the phone dried out the screen slowly came back to life and became responsive again.
I suspect that you have moisture egress into the device, it could cause a strange capacitance differential affecting the digitiser, or even just a short.
Have you used the phone, in shower room, in pocket while exercising. In rain. Taken it from cold outdoors, into very warm indoors. All these things can cause moisture to condense inside the device.
If it happens, the symptoms will reduce as the phone completely dries out...

after a while the screen start to response in a normal way...
i tried swift keyboard and guess what.... the same issue again....
this is weird...
note: try to remove the grip shell
Solved,
Okay so I had this issue just now and i got worried, but there is nothing to worry about. The problem is in the charger, use a different charger
my 2 have done this a couple times and I think they were charging at the time. I unplugged the charger but no change. Then I removed the silicone cover I put on and it immediately worked fine both times I did it. I did not turn phone off or reboot. It did not start this trick until I put the covers on. Covers barely touch the screen on the sides. When I replaced cover it still worked until the next time it became unhappy with the cover. Anybody else...................
Update-just checked my other phone. I removed cover w/o unplugging and it did not restore it. Unplugged charger and it was fine. Almost seems like both are contributing to it. more research necessary..........
Maybe the phone just wants to be fondled???????

thank god for this, how long will it take to final all dry out?
The front face buttons dont work, just under the touch screen, the home button, settings, back, go and enter button, right at the bottom of the base. not the slide out keyboard. I have rebooted the phone several times, if I slide out the keyboard I cant use the buttons under the screen. yet my slide out keyboard buttons work just fine. i hope its not dead and its time for a new phone because I only like phones with keyboards, I hate touch screen keys. Do I have to buy a replacement part and is it hard to repair yourself?
If it helps anyone I also noticed that the center or enter key is red but if you look closely at it, its always on it just wont turn off like it used too, and now Im getting prompts that read superuser has been denied. I dont understand why I havent done anything or updated anything. not sure if I should flash the rom again and start over its been working fine the last 8 or so months all of a sudden its been acting up today
There is a small ribbon that connects those buttons, more than likely this is all you need to replace and you should find it for 10$ or less on eBay
Disassembly is easy except for getting to the LCD (which you need to do) just need a hair dryer to loosen the sticky on the back of LCD and be careful taking it off so not to damage LCD, the rest is simple
Best of luck
