    I don't know if it is a coincidence or not, but after enabling the "kids corner" i haven't blinking issues until now. For those that have the flashing screen, can you try this? Let me know the results!

    I saw it once or twice, but more rarely with kids corner. I have my eye on the phone for the last 4 days, it seems this is a small fix. However it is something they should be fixing in fw.

    I have had kids corner enabled all the time, before the denim update and after it. The flashing screen appears every day and I have not found anything that makes it less often.

    I sent the phone for repair, hope they fix it. Of course if they even manage to reproduce it, because on the description of the problem the guy in the service just wrote "sometimes display blinks".

    However before sending it I tested with flight mode, and turned off auto brightness, enhanced touch, other ease of access options. None of these fixed the problem. I'm pretty sure it is not caused by any 2G, 3G, 4G, WiFi or other radio interference and improper shielding. It is something else for sure.

    If they cannot fix it probably should wait for a MS update.

    this exact same thing happened to me as well. And just like you ive come to the conclusion that its a HW problem where it seems to have a bug in the power circuit of the display. hopefully they can release a software fix, IF THEY LISTEN TO US.

    I have the same problem. Seems like pure software glitch. When scrolling fast there seems to be some flickering like the picture is not updating correctly and some bits of earlier frames show up just a fraction of a second.

    It's good to read all this, since i thought my phone screen is broken again. Hope that the flickering really is on the software side and an update fixes everything more sooner than later :D

    It started doing that after some updates, so it should be fixed in some update hopefully soon.

    I suspect the flickering is there to stay. The AMOLED screen has a zillion LEDs to turn on/off for the three primary colors that are used for each pixel, Red, Green and Blue.

    IF the CPU is busy doing other stuff, then the processor time is shared between all of the different things. It may be weighted in favor of the screen, but not totally, so the flicker coming and going is normal. That some are experiencing worse flicker after Denim suggests that time share priority to each CPU cycle has been changed.

    To test this theory you could turn off all background tasks that you can. Then disconnect wifi and turn off radio (if possible) and then let it sit for a few minutes to let the CPU load (if any) settle down. Then, test for scrolling jitter and flicker where the CPU has little other stuff to share it's time with.

    Just look at the PPI (440) of the AMOLED versus the LED (around 290-330) screens and understand the work load that has been thrust upon the AMOLED. Little wonder that the next phones from msoft are going to have 800MHz processors, maybe even 64-Bit, the 200 and 400 are not cutting it with AMOLD. Also note that 64-Bit will not make much difference to the screen performance though, but the 800MHz will.

    This is not a very clever consideration. I'm sorry if you are offended by me, but it worked well before the Lumia 930 got updated to Lumia Denim. And this issue occures on my Lumia 930 mostly while browsing (no other programs opened at this time). The phone is not hot or warm at this time, so the processor does not have too much work to do.

    One time the issue occured (I was browsing), I turned on the flight mode, but it does still this flickering (the phone was totally cool). Other Phones have also AMOLED Screens, even with higher resolutions, and they don't have this flickering (and these phones run on Android, which needs more cpu power to run the system then WP). I also have no jittering, the flickering is my only issue.

    @Ivaylo Badinov what happened to your L930?

    Unfortunately I had to return my second 930 due to this issue. It seems to be exacerbated by the Lumia Demin update, though I noticed that the screen did flutter slightly on Cyan - not enough to affect usability, however after updating to Denim the flickering got worse and worse until it was actually worse than on phone no 1 - the flickering was based on horizontal lines all over the screen. The flickering is so bad that it would surely be a danger to anyone with epilepsy. Microsoft need to be alerted to this as it could get them in trouble.

    The phone also got warmer than the previous phone, the screen kept going black (not anything to do with sleep) and crashing - all I could do was restart the phone - I didn't have this issue with the previous phone.

    I also discovered that despite taking photos of the same objects / views (did not take out of the house as still within returns period) the photos were coming out very dark and the camera could not take decent photos even in good light - this was on auto setting. There was nothing wrong with the camera on the first phone - I compared similar photos taken in similar light on One Drive - I cannot remember whether I took the photos whilst on Cyan or after Denim on the previous phone, but I feared that the camera sensor was faulty so that was another reason to send it back.

    The headphones would only come out of one ear when inserted into the phone, however if I restarted the phone I got stereo. I also had this issue on the previous 930.

    I wanted to run try out the phone a bit more this weekend and send it back on Monday but this time when I printed off the returns label Amazon requested an immediate return instead of allowing me another 30 days to return it as the previous time so it had to go back on Wednesday. I could not get a replacement this time either as Amazon had suspended the phone from sale - it's now back on sale but I have decided to leave trying out a replacement until after Easter one year after the phone was announced in the hope of getting later stock. I think after this month this phone will go out of production as Microsoft have announced that they are closing the Nokia factories in China at the end of the month - hardly a surprise given the quality issues. I doubt production of this phone will get transferred to Vietnam as it wouldn't be cost effective and it has lost nearly half it's original value.

    I had a email conversation with a support employee of Microsoft. It seems like they're working to fix the issue. That's the answer I got yesterday:

    "Hi XXXX,

    My name is Riley with Xbox Global Escalation Support. I have looked into this a bit more and want to share what I was able to find.

    Looking into the case notes, I found that you are encountering a known issue for which our engineers are currently working on determining a fix.

    At this time, I am looking to get an estimated timeframe as to when a resolution will be deployed. Please be assured that your case is important and I will make every attempt to provide you with an update and/or resolution as quickly as I am able.

    I will follow up with you in a few days to let you know if I have heard anything. If you have any questions in the meantime regarding this issue, please feel free to let me know and I will be happy to help.

    Thanks again for bringing this to my attention and I look forward to getting this resolved! Expect to hear from me soon.

    Sincerely,

    Good to know they are working on it.
    Hope they'll find a fix, not as Google's Android bugs (on their fooking Nexus device) that never fix or even care about.

    Thanks for sharing mate! Please update if you got any news.

    I think that the xbox support is responsible for both xbox and Windows Phone and that there's no seperate Windows Phone support. We've had a longer conversation then just one e-mail, he first gave me some Basic instructions.

    After I've done that, I wrote him that nothing has changed and I think that he inquired at the section responsible for phone updates/fixes, because it actually took some time until he wrote this e-mail.

    I just use the microsoft live chat (UK) and ask them a few questions about any minor update and about this specific issue, if the team knows about it and working for a fix of it.
    They said that there have been not reported issue about this one. (pretty weird)
    Anyway they'll pass it to the team for 'invastigation', also I mention this specific forum and topics about this issue around the net, that probably casued by the last update (Denim).

    I guess we all need to report this bug (customer support, live chat, whatever...), if this issue still not a "well known" by customer support team then we'll get WP10 and the bug will persist! I bet they won't back to the desk that fast to fix this "little" issue after the big wp10 update.

    BTW - anyone knows if this issue is only on 930's or other devices too?

    Display issues which I face on my 930 are pretty similar.
    1) Slight flickr when scrolling the screen.
    2) Millisecond blinking of display (becomes black)
    3) Green and purple tints usually appear for few seconds and then the normal colour is retained. (especially before unlocking).

    I did think of giving my phone for repair, but the Nokia care men said that the device is only like that, nothing can be done.

    I also checked out my friend's 930, his phone too had slight flickr. I don't think its an hardware defect because many phones have the same problem.
    May be, the display itself is like that or it might have some software bug.
    Have to wait and see how MS responds.

    Btw my lumia 930 runs on denim in India.

    In the german Mobile Community forum of Microsoft, a support member just answered in a thread about this issue.

    The answer is: "Our developers were able to reproduce the issue. They're working on it and the issue will be fixed with the next major update."

    So, the question that remains is: Will the next major update be Windows 10 or will it be earlier?
