Touchscreen unresponsive - Nexus 4 Q&A, Help & Troubleshooting

I received a Nexus 4 in mid December. Since then, the touchscreen has become unresponsive 3 times for extended periods of time. The hardware buttons work, and the phone continues to function normally in all other respects as well.
The first time (12/25) I chalked it up to some edge-case bug. The second time (1/1), I called Google and requested an exchange (As with many others, the replacement device has yet to be shipped). I went through a factory reset via recovery with tech support. The touchscreen remained unresponsive after the factory reset, which suggested that the problem was either somewhere outside of the Android userspace, or in the hardware itself. I packed up the phone and waited to hear about a replacement. After a few days passed without word from Google, I decided to try the phone again, on a whim. It worked! Until today (1/8). We'll see if and when it becomes responsive again.
Anyone else with this issue?
Here's an observation I can't explain: 12/25, 1/1 and 1/8 are separated by a constant number of days (7).

Sounds like a screwed up digitizer. I'd get a replacement before the 15-day period is up. Regardless of whether it's working perfectly now or not. Three occurrences in such a short period can't just be a random bug. Sounds like a hardware issue especially if you're stock.

That's right--I am stock. In ancipation of precisely the situation I'm in now, I thought I'd wait a month or two before risking any modifications.
I passed the 15 day period, but I did receive an RMA authorization one week ago. Now it's just a question of when the replacement will be shipped.

Looks like a replacement has shipped. 5 business days, within the quoted 3-5 business day range.

Received RMA replacement. So far, no issues (touchscreen or otherwise). Currently at 4.2, and I have not accepted the update to 4.2.1. I have no evidence that 4.2.1 had anything to do with my issue, but I can wait to update just as well.

touch screen stops working

Been using mine for a couple of weeks, but just now the touch screen has been acting up. Sometimes it responds sluggishly and sometimes not at all.
At first I thought it was one of my apps running in the background, but even after a soft-reset, the touch screen still doesn't work. Can't even enter the PIN to my sim card.
Found that if I gave the screen a few solid taps here and there, the screen would start working again.
This happen to anyone else?
I've got the same issue. I can't find any reliable way of getting the screen to respond apart from to get someone to call me and then after some bashing on the screen it starts working again. I've even updated to the latest ROM in the hope it would cure the problem - but it didn't. I contacted HTC support they offered to repair the device...

Yep, that happened to me plus the screen started jittering with some weird actions. I sold the device and ordered a new one, to be delivered dec.19.

I've contacted Handtec about the issue, my phone's just marginally inside their 28 day replacement policy so hopefully I can get a new one out of them.
I tried a hard-reset before, didn't fix it. And I've found that if I place my entire palm over the screen and give it a bit of a squeeze then that restores life to the screen for hours or days at a time

Sounds like the connectors under the screen came loose, either because it was dropped or just shouldn't have passed QA. Definitely a candidate for repair/replacement.
By the way, if this happened even after 28 days you would still be covered by warranty...no matter what some dodgy resellers say

Oh of course, but the regular warranty process is to repair the phone. Being so new, I'd want a replacement.
For what it's worth, I posted a message asking about this same fault a couple of weeks ago but with no replies. I emailed HTC and they said it was probably a hardware fault and to either send it to them for repair or contact my supplier (O2). I spoke to O2 and they suggested that it might be because my SIM card is a few years old and suggested trying a new one. I thought this was worth a go so they sent me a new card but the screen still becomes unresponsive and the fault also survives a reset. In fairness to O2, they are now sending me a replacement unit which should arrive on Monday.

The same thing happened to me. I think it was because I left it in my hot car. HTC fixed the problem, for free, inside warranty, and just sent me back my phone 2 days ago. It's even got a brand new screen. NO SCRATCHES>

I sent my back and the first time it came back and worked for a week and then stopped working completely. I sent it back a second time, they paid for shipping and ordered a new screen and replaced the old. Nice thing, I bought the phone used and the warranty was still intact.

[Q] HELP - Unresponsive Screen

Hope any of you guys can help me on this. Last night my Leo's screen went totally unresponsive.
Could not get past the screen lock. Removed the battery, rebboted ... could not get the PIN code in.
I had seen this already two nights ago, but it got away once I moved in an area where I could get a reasonable signal (ultra-crappy where I am now on vacation).
Now Im'm beginning to think the signal thing was just a coincidence and that the problem is way more serious.
In total despair, I even tried a hard reset. To no avail.
Phone boots up fine. I can even sync to it (so yes, I can get to the registry). But since the only control is the screen ... not really a lot I can do with it.
I need to be in touch for work and I badly need the voice and internet connectivity (right now I'm using the wife's phone ...).
Any ideas besides getting an RMA from HTC?
Thanks a lot in advance.
Update: spoke with HTC support.
It looks like the issue is somehow triggered by the lock screen.
As suggested by HTC, I flashed again the 1.66 ROM upgrade and everything ran smoothly until the phone went in standby the first time.
Then, I was (and still am) unable to unlock the screen. And if I soft reset screen is unresposnsive again.
Right now I can just receive calls (I removed the PIN code from the SIM temporarily).
HTC told me to send it in for repair, but everything in Italy is closed until Aug 23rd and the only option I have is to ship it at my own expense to the UK and back (HTC will collect and deliver free of charge only within the same country).
Total bill some 100+ Euro plus driving 100 KM or so to the nearest courier collection point. A nightmare.
What really troubles me is that the problem surfaces only once the screen locks.
On one hand I follow HTC's support that if flashing 1.66 did not cure the issue, it cannot be software.
On the other hand, if it is indeed hardware, how come it freezes only after the first lock screen? Lock/unlock is a software thing. Screen should behave exactly the same way before or after the lock - shouldn't it?
Anyone here seen/heard of anything like this?
wow, gotta love those "closed for the summer" euro vacations.
If you reinstall the ROM, then why not disable the lockscreen until you can get it fixed?
You can install BSB tweaks and that has an option to disable autolock.
i had the same exact problem; it started freezing only on the lock screen then got worse and started freezing at random times while in use. I finally broke down and sent it in to HTC to check it out. I'm waiting to hear back with there diagnosis and I will pass along whatever they tell me.
Good to know the problem has come up somewhere else (if you're the only one you are most likely to hear it's your fault before they replace the most expensive component in the phone). Where are you located slimster?
How long have you been waiting for? HTC policy should be 7-10 working days from when they receive the phone at the lab (so they told me and I remember reading it somewehere here in xda too).

HTC Repair Diagnostics?

I was just wondering, but does HTC perform truly extensive tests to ensure that the problem with a device in present? The reason I ask this is because even on stock winmo, my HD2 suffers from random reboots, sometimes it may take almost 3 hours, sometimes 30 minutes. I am sure this is not rom or battery pin related.
I suspect that they will do as few tests as possible for them to find a fault or decide there is no fault.
When I RMA anything I always include a full explanation of what, how and when it fails and how to recreate it if possible - it normaly works
That is what I was afraid of. I do not want HTC testing it for 5 minutes and decide there was no random reboot.
just got my hd2 back from them yesterday not only did they replace my screen they fixed my camera and outer case for no extra charge, 120 cheaper then insurance and less hoops to jump through , although after you recieve email that says they got your phone call them dont wait for call back wouldve saved me 5 days still all said and done 2 weeks 120 and almost a brand new phone hope this helps
Was your touchscreen dead? I am supposing that that is a easy test for HTC. But trying to a find random reboot?
If I had to guess, I'd say that their process is something like this....
Check for obvious hardware fault...
If found, fix it or send out a refurb
If it's not a hardware issue, check SPL...... If its stock, reflash. If it's not, send it back.

[Q] Atrix touchscreen problem

I just purchased this phone and I am having a problem with the touchscreen not working correctly, at seemingly random times (but very often). The screen, as well as the capacitive buttons, will freeze up and I have to lock/unlock the screen for them to work again. Sometimes it will freeze up after only one touch after the screen is unlocked, other times it can be a good ten minutes of working fine. I've tried factory resetting it and the issue is still there.
If its that new try a factory data reset. settings/ privacy/ factory data reset. If it doesn't solve it return it and get a new one.
Sent from Rob's Atrix
I tried that already but the problem persists. I would return it but I've already had to return one for a different problem and would not like to do that again as the seller doesn't pay for return shipping and it took about two weeks for me to get the replacement, especially if I am just going to get another phone with issues.
I had a simmalar problem took it to the store I got it from and they sent it to Motorola and 1week later I got it back with replaced screen and internals. Worked good ever since.
Ps Mabey third time will be the charm.
I guess it's just a hardware problem then? I might hold onto it for a bit and then if it gets worse I'll send it to Motorola since the factory warranty should cover it, right? (last night it's been a little better since I took out my sd card, I'm not sure if it's just a coincidence though)

How reliable is the Yotaphone 2 Hardware???

I am asking this because I have my YP2 for 2 months now and it´s already the second time I have to send it in for repair...
The first issue was a clear hardware defect - I left it on the kitchen table around 4 weeks after my purchase with the e-ink on top, and when I returned later during the evening, the clock was ~90 minutes behind, did not move, and the device was not reacting to anything. I´ve tried the 10 seconds reboot thing on the on/off switch (a few days earlier I managed to get me into a software loop while fiddling with the stupid multi-user mode of Android 5... and the hotline guy gave me the idea for a reset with this 10 second thingy) and nothing happened... I had to send the device in.
10 days later it came back, "new mainboard" with a new IMEI, from the outside it was still the same (even my sticker was on).
Then a few days ago, only 2 weeks after the return, my camera did not switch on. Standard Android failure message. Then I realised that if I press the two screens a bit together _sometimes_ the camera comes back, from time to time with a dizzy, blurry picture, sometimes with a strange split screen (upper half of the picture down, lower half up) and sometimes just snow. And then again most of the time the Android failure message and no pic at all.
So the phone is going back to the service AGAIN... Seriously, I have never had any kinda bad luck like this with any other phone in my last 20 years before! Of course the whole setup/install procedure has to be done again (and since I am using the phone professionally, with that amount of files and apps and widgets that takes at least 3-4 hours - although I am starting to develop a sort of routine here... ) and so on.
In conclusion - because in some other topics some of you already mentioned RMA issues... - my question would be: How reliable is YP2 in your experience? Does it make sense to keep using mine, or should I sell it as quickly as, and with the smallest possible loss possible on ebay and return to more satisfactory models? I mean, I LOVE my secondary e-ink screen and things I can do with (and thanks to) it! This makes my decision even harder, since the other contestants with double screens have next to NO software support on their devices for a proper use of the e-ink, at least compared to Yota who really invested into that as well...
Sounds like you've been cleaning out Yota's monday models for everyone.
Personally, I've had mine for 6 months now and only run into some software related problems. Yota has said that they are working on bringing Android 5.1 for yotaphone 2. Hardware has been working flawlessly.
You should create a full backup of your phone before sending it in. Then when you get it back just restore it and you're up and running within minutes.
If you keep running into problems but appreciate the epd, you could sell your yp2, get some cheap replacement phone for 6-12 months and then buy yotaphone 3.
Well, in the first case when the phone completely froze there was no way backing it up
I considered doing so however the last time before I sent it in for the camera issue, but specifically _because_ of all these Hardware-issues I wouldn´t want to mess with the rooting option - and without root, there is only so much you can backup...
Still, my K9- and Nova launcher settings were done within seconds, as were the messages and call logs and google-related stuff. For the rest... well, as I said, I´m starting developing a routine Hopefully it is worth the effort and once it comes back now, it will do it´s job like ALL my previous phones did. Otherwise I will sell it and return to Samsung and never touch a Yota again...

To create a full backup, you don't need to root, but you will need to unlock the bootloader. Basically you would first unlock the bootloader, then boot (not flash) into a custom recovery, create your backup, transfer it to your computer, and you would be done. The only thing that would have changed and detectable afterwards would be the unlocked bootloader. However, I don't think that they would turn down your hardware related RMA because of that. That is not a verified assumption though.
Edit: It would seem that some manufacturers might turn down the RMA for unlocked bootloader, and some might not. Yota has not made their stance clear on this.
