Screen flickering and camera hangs

I bought xperia Z1 a month ago. Since then i have this issue of screen flickering. i ordered for replacement and the phone i got after replacement has same issues as well as the camera hangs.
Any suggestions why this happens ?!!!!!!!

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
I suggest that you to run your phone in safe mode for a while to check if you still experience this. If not this may be caused by any downloaded application.
How to boot into safe mode?
If it's the same while in safe mode, I suggest that you try to repair the phone software using PC Companion..
Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.
How to backup?
If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.

Just upgraded to OSX mavericks on macbook pro mid 2011 version. Having a big issue here that whenever my mac comes back from sleep, i.e after I open the lid, the screen flickers and there is an error of Finder not opening properly. Any fix to this?

My daughter has had her Razr for about 9 months now. About two weeks ago she picked up her phone in the morning on her way to school when she noticed two cracks, both starting at the camera lens. One goes completely to the bottom and the other goes sharply to the side. She has never dropped it and me and my husband went over it with a fine tooth comb. We looked under a magnifying glass and could no find any reason for the glass to crack. Not one ding, scratch or bang. Our daughter really takes good care of her stuff, but we still wanted to make sure before we sent it in for repairs. Well we did and we got a reply from Motorola with a picture of the cracks saying this was customer abuse and that it is not covered under warranty. Even though they did not find any physical damage to back it up. Well I e-mailed them back and told them I did a little research and found pages of people having the same problems. Well I did not hear from them until I received a notice from Fed Ex that they were sending the phone back. NOT FIXED!!! I went to look up why and guess what there is no case open any more for the phone. It has been wiped clean. I put in the RMA # it comes back not found, I put in the ID #, the SN# and all comes back not found. Yet a day earlier all the info was there. I know there is a lot more people like me and all of you, but they just don't want to be bothered so they pay to have it fix, just to have it do it again. Unless they have found the problem and only fixing it on a customer pay only set up. I am furious and will not be recommending this phone to anyone. And to think I was considering this phone for my next up grade! NOT!!!!

Why the screen flickers and moves from one app to another by itself without being touch?

Have you tried a reset to see if that fixes it ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

Are you an owner of a yogo 2 pro? If not, then you have no idea. You can't sit back and defend lenovo by modding us or hindering any potential efforts via discussion. You can't in good concience sit back and believe this to be ok.
Regarding paragraph 1:

Regarding paragraph 2:
1- I have a Y2P, but don't have the issue described in the thread.
2- The moderation applied was not a defense. It was an application of the Guidelines.

Why is my iPhone 6 Plus home screen flickering and freezing up?

Why is my iPhone 6 Plus home screen flickering and freezing up?

Try these steps as needed:
1. Reset phone - press both home and lock buttons for at least 10 seconds, releasing when the Apple logo appears
2. Restore to factory settings:
Use iTunes to restore your iOS device to factory settings
3. Get warranty service from Apple in the country where the phone was purchased

Screen flickers and goes black on boot up.

Have an older white MacBook that when I boot up, screen flickers and goes black, MacBook does power on.
Any suggestions?

I am seing a similar issue with a 13" White MacBook.
Powers on ... chimes ... then screen goes blank as if the machine has gone to sleep. Hitting the Return key or the power button wakes it again, but only for two seconds ... and repeat!
Any help gratefully received!

My screen flickered and now all I get is black and white pixels - any ideas for a fix before I take to the Genius Bar?

MacBookPro is about 8 years old now so has had a good innings. Last night the screen flickered, and then went off. Turning Mac back on again brought black and white pixels - small rectangles all over the screen. In background is little apple in middle of screen with the round rainbow timer thing vaguely visible. This then sticks and I just have the pixels nothing else.
Any ideas?
I have booked with Genius bar tomorrow but am feeling bereft!
Thanks in advance.

It's certainly a hardware problem that only Apple techs would be able to properly diagnose. Keep your appointment...

Screen flickers and photoshop becomes slow

Hi,
I have been using photoshop for quite a while now and have never faced any issues until now. I upgraded from windows 7/64 bit to windows 8.1/64 bit and the problems have started. When I turn on the ruler view my ruler flickers and also the photoshop becomes slow. If I hold the spacebar(hand tool) and want to move to some area it's not smooth. When the ruler view is turned off it's all fine but as a web designer I can't do without the ruler. Earlier I had the whole screen flickering issues but I did some search on the internet and have tuned the drawing board to basic and that has solved the issue but not the ruler flickering issue. BTW I am using Photoshop CC. I am unable to work on it and I need some help please help me guys.
Thank you

Why is my 2007 HP V17 monitor screen flickering and going black?

I have an old 2007 HP V17 monitor attached with a VGA cable to an early 2008 Macbook running on OS 10.6.8 software via a DVI- mini connector (this is also my desktop computer).
About 6 months ago, the HP display started going white and sometimes gray for a few seconds before the image would return, and a couple of times I had to unplug it and restart the Macbook before it came back. I followed Apple's instructions for testing whether the problem was in the computer (= resetting the system by resetting the Mac's parameter RAM and SMC), but the computer tested okay. I then purchased a new VGA cable and DVI-mini connector, but the problem persisted.
Today the HP screen suddenly went black (first time going black) and stayed black. The power button stayed lit and if I pressed the Volume or Auto buttons, the "Volume" etc. message boxes did appear, so the device's backlight is apparently working and not burnt out (unless the backlight has nothing to do with the message boxes showing up, which for all I know may be the case). However, the Desktop showed up only on the Macbook.
I checked all the connections, removed the DVI connector and plugged it back into the Macbook several times, but the HP screen stayed black, so I removed the DVI connector in order to type this message on the Macbook. Then, as I was writing this, I decided to plug it back into the Macbook one more time--and sure enough, the display is back!
I love this monitor, which is the perfect size and ergonomic height for my setup, so I'd hate to have to replace it. Can anyone tell me
Given the information above, what's the probable reason for the flickering and going to black? If it's the computer, what could it be? Can I solve this problem myself? (See above; I couldn't find any other ways to test the computer in the Apple articles database.)
If not, could a monitor this old be repaired?
If so, how much would repairing it cost, since buying a new monitor that I probably wouldn't like as much would cost upwards of $300?
Thanks so much for any advice out there!

Hello @turtlewiz,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand that your HP V17 Monitor has gone black and is not displaying anything. I am providing you with some steps for you to try below:
Step 1. Unplug the power cord from the back of the monitor and the wall
Step 2. Hold the power button down for at least one minute
Step 3. Plug the power cord back into the monitor and then into the wall outlet (not a power bar or surge protector)
Step 4. Press the Menu button on the monitor
Step 5. Navigate to the Factory Reset option and select it
If the issue persists after this you can try the monitor on another computer to see if it continues. If it does it appears to be a physical issue and I think it would be best if you contact HP Technical Support for repair options.

MacBook Pro screen flickers and freezes after Snow Leopard/Safari 5 updates

Hi guys,
I have a silver 120GB 15-inch MacBook Pro from Summer 2007 with 3GB RAM and 25+GB free space which has recently begun to freeze irrecoverably. The first appearance of these symptoms seems to coincide with my installing the Snow Leopard 10.6.6 update via Software Update.
I'm not particularly well versed in computer technology, but will try to describe my problem as detailedly as possible.
What happens is this:
1. I start the computer as per usual, with only a couple of startup items. Everything's fine.
2. I start working. Use a lot of Safari 5 for browsing websites, often with some kind of Flash or "Flash-type" content such as banner ads, videos, even full Flash designs. I may also have programs such as QuickTime, VLC or an image editor open, if not necessarily "actively" doing anything. Everything's still fine - I'm able to both browse websites and watch videos as usual.
3. After a while of active working - say, 1-3 hours - I notice browsing websites gets a little choppy. Display features such as the file list view in Finder may or may not appear properly. The rotating wait cursor may or may not appear from time to time.
4. Immediately after symptom no. 3, the next time I start to watch a video, either via Safari 5 (say for example something on DailyMotion.com) or a file via QuickTime, something goes wrong.
Following no. 4, one of three things invariably happen:
5a) The video freezes and the entire screen flickers from black to the screen view very quickly two or three times, after which the computer or screen appears to freeze. The cursor still moves, but nothing reacts to it - open windows become completely unresponsive, nor does the top or any other menu react in any way to clicking. The "menu row" of application items, which normally appears when I move the cursor to the very bottom of the screen, doesn't appear. Restarting "blindly" by pressing the Off-button once and pressing R doesn't work. I'm forced to do a hard reboot, after which the computer is once again fine until the next two hours of active working. This usually happens ONLY when I try to watch a video in Full Screen-mode.
5b) I notice the video freezing only just in time, and am able to pause it and "esc" out of Full Screen-mode, and the computer remains operational. However, as soon as I again try to play video in Full Screen-mode, everything described in 5a. happens.
5c) The video stops playing, and the screen reverts momentarily to pale blue before switching to the login screen. I login again with my details, and everything appears to be fine again until the next two hours of active working. The computer "starts up" a lot faster than with a hard reboot. This usually happens ONLY when I've tried to watch a video in its original size, i.e. when not in Full Screen-mode.
This happens 1-4 times a day, and it appears to depend directly on how much work I've been doing on the computer. The less I use it in the course of a day, the longer it takes until the next time it freezes.
So, in a way, I'm able to replicate this problem. 95% of the time the screen has frozen while watching or starting to watch (usually already when starting to watch) video footage, but it has also frozen a couple of times just switching between e.g. Safari 5 and an image editor or browsing a website with a Flash banner ad or embedded video content (which however hasn't necessarily been playing); today, the screen froze when I tried to open a website made entirely with Flash.
Although it could be just a coincidence, I believe this issue first appeared when I updated Snow Leopard to 10.6.6 via Software Update alongside some other pending updates, including as far as I recall one for Safari 5. The update process appeared to have gone well at the time, though, and was not interrupted in any way. I have never had this specific problem with the computer/screen before, though.
I've read a couple of threads here regarding very similar issues with newer MBP models than mine, in which it has been suggested that the fault may lie in a malfunctioning NVIDIA GeForce graphics card. Now I've had that replaced already once because my screen went unexpectedly completely blank after a forced reboot 1-2 years ago (I don't remember exactly), but according to my System Profiler info the card still a GeForce 8600M GT. Can it be failing again?
I've also had some kind of a RAM card failure once. As far as I understood it, one of the RAM cards had fried and was preventing the computer from starting up. I replaced the bad 1GB card with a new 2GB one and the problem was resolved. Before the computer died, there were also other symptoms, but they were not similar to these.
I'm also doing the Apple Hardware Test tomorrow. Any other suggestions, though, than the graphics card?
*Could this have to do with Flash or Safari 5?* Just hear me out. Even though my computer has frozen from watching a video in just QuickTime, Safari 5 has always been open in the background at the same time, and more likely than not with websites with "Flash" content open. And come to think of it, before I performed the Snow Leopard and Safari 5 updates, I used to have daily problems viewing Flash video in Safari 5, the video content either suddenly showing up as "Plug-in Failure" or crashing the browser; I've had both Safari 5 and the Safari 5 Flash plug-in "quit unexpectedly" countless times in the past, almost daily. Sometimes the "Plug-in Failure" could be fixed just by refreshing the browser view; at other times, Safari 5 would stop showing Flash content altogether - Flash banner ads (such as Google ads), YouTube and other Flash videos, everything - until I quit and restarted Safari 5. BUT - since the day I updated everything via Software Update, I don't remember this happening; it never gets to "Plug-in Failure" now. Could it be worth trying to use e.g. just Firefox for a while or is there something (e.g. Adobe Flash) that I could try reinstall? Or am I just clutching at straws here?
Thanks for reading this long, long post!

Do you have access to an Apple Store? If so, it may be worth making an appointment at the genius bar and having them run the test for the NVIDIA problem. Since your replacement logic board still has the NVIDIA GeForce 8600 M GT video chip, it could be starting to happen to your replacement logic board.
I also agree with all of CMCSK's suggestions. Freezing is often associated with hard drive problems. You might also want to run SMART Utility:
http://www.apple.com/downloads/macosx/systemdiskutilities/smartutility.html
You can download the demo and run it several times for free. It will give you a very comprehensive view of the physical health of your hard drive. If you still have the original one from 2007, it's getting pretty long in the tooth and may be approaching the end of its average useful life of 3-5 years. I just recently had to replace my original 2007 Fujitsu drive.
If your drive is headed south, and is also too small, it may be time to upgrade to a larger and faster drive.
The software update probably didn't cause the problems, but it may have exposed problems that were already in existence.
Good luck!

Screen flickering and running hot

I have had this laptop for five and a half years and all of a sudden the screen is constantly flickering and changing color. It also seems to be running warmer than usual as well.
I don't want to have to buy a new one. What could be the issues!?

Any answer yet? Mine is also early 2011 model. 13 inch. OS X Lion

MBP 13" Screen Flickers and Freezes After Upgrading HDD

Hi There,
I have seen on here and a few other forums that people are having issues with graphics cards or overheating that is making the MBP screen flicker and freeze.
Mine has been fine until yesterday when I installed a new Seagte 1tb HDD. It works ok, but every now and then the screen starts to flicker, half of it goes black and the system freezes. Sometimes it's just for a few minutes, but sometimes I need to do a hard reset by holden the power button down for 5 seconds.
Here are the details:
MBP 5,5 13" (2008 I think - Can't remember)
Boot ROM Version:
MBP55.00AC.B03
SMC Version (system):
1.47f2
Version 10.6.8
2.26Ghz Intel Core 2 Duo
8gb 1067 Mhz DDR3 (Just upgraded, but before the hard drive and no issues)
1TB Seagate Momentus SATA HDD
As mentioned, I upgraded the RAM a week or so ago and it has been running fine. I put the new hard drive in last night and after a few hours, the flickering started.
I cloned the hard drive using SuperDuper and it all started up fine.
So far, I have verified and repaired permissions, checked SMART status and run a SMART Utility diagnostic. All comes back ok.
I cleared the PRAM and installed smcfan control as another forum with similar issues said it was a overheating problem and running the fan control program should fix it. I did that at 8am this morning and it has run great all day. Come 5.30pm, the flickering started and then it froze.. GREAT!!!!
It's so frustrating, I was really looking forward to having my MBP upgraded and running fast again.
Any ideas or tips would be very welcome.
Thanks in advance.

set old HD. If problem will gone - you have weakened power supply or internal power converters. Yours new HD draw more power during spinup or something - so voltage on internal bus lowers and memory or videocard freaks.
5.30 PM looks like a time when there begins a lot of load on city energy grid - so voltage in wall socket goes a bit unstable, it may also add to problem.
if problem is gone when you are on battery power - its power supply. If it persists or get worse when on battery - its internal power convertors.

Screen Flickering and Dimming?

A little while ago my iphone screen started flickering from bright to dim out of nowhere. Sometimes it would just keep flickering and sometimes it would stay dim. Ive read some forums about this and they say if you press on the upper right corner it should stop. I tried it and it just kept going. I didnt get it wet or drop it hard anywhere so i dont know whats wrong. What could be wrong with it?

Thanks so much Linc, that's really useful to know.
I had to do the same thing with my last Mac Book Pro when the graphics card completedly died suddenly!
