[Q] Screen flickering under WiFi data transfer

Hi,
I have my sgs about 2 months and I'm very happy with it. The only problem I have is, that sometimes there are strange displayinterferences.
It looks like there are moving waves from top to down.
Does anybody have this troubles too and has a solution for it?
Or is it an hardware error? The problem is that the error isn't reproducable.
Maybe somebody can help me, please!
Thanks in advance

I think I have also noticed that once or twice. I believe it can be seen when you have the android drop down menu (notifications etc) open and you start or stop WiFi. It must be some kind of interferance with wifi hardware. Normal wifi operation does not cause it, only the startup of the WiFI which lasts one second or so.

Yeah, i think this could be true. I also see it often, when I open die Notification bar. But I also have the same interferences, when I am working in apps. Maybe also the 3G connection could be the reason? Does anybody else have this problem.
Is this a problem, which I have to life with or could this be an error of the hardware(warranty)?

I have the same problem. Never on wifi tho.
Which firmware are you using?

Hi,
my firmware is I9000AUJF1(A1 branded from Austria). I don't know if the problem in your posted thread is the same. The interferences I mean only exist one or two seconds. There are horizontal dark lines which moves from top to the bottom. After some time everything is OK again. It looks like anything interfers the display(wifi, 3g?).
The problem of warranty is, that I'm not able to show the problem, because it's not reproducable.

Screen flickering under WiFi data transfer
I noticed this problem a couple of days ago.
Whenever there is some data transfer going on over WiFi, wherever I am browsing or some service syncs up the screen starts flickering and I have what I can describe as faint scan lines crossing the screen vertically like there is some sort of interference.
These are mostly noticeable on white and light grey backgrounds.
I have gone trough 2 firmware updates currently being on stock JPK rooted.
I have searched around on google and found on some forum one guy that was saying the cause is an interference between the WiFi module and the screen refresh rate.
Has anybody encountered this problem or these symptoms ?
Is there somebody around more knowledgeable in this issues that can confirm that this is a hardware problem ?

wow! , you might have a defective phone then.
I use WiFi very often, Wireless N at aprox 87 Mbps
that should be high enough to reproduce the problem you experienced, if i had a faulty screen
the description of the scan line reminds me of interference when you are in close proximity with another LCD or CRT screen causing the distortion field

OMG, I get this too. Usually happens on boot or when I'm browsing a data heavy website or using Android market. Are our phone defective? Does anyone else have this problem? I wonder how common it is.

does the scan line comes from bottom up
or goes from top to bottom?
very slowly or fast?
if you are pluged in and charging, also are you in a 120v or 240v?

They tend to be random and I'm on battery power atm. Also they're quite fast but don't last very long. They'll start then stop then start etc ..

Hi,
just for your information. I've sent my phone to samsung on friday. Maybe they find the error. I report, if there are new information.

Yep i have the same problem. Can t find the source though....

The lines appear from top and travel the screen fast.
Imagine a TV who for a second has problem with reception.
I am on 240 V.
Also the issue is much more noticeable when not plugged in.
If I have the phone plugged in its barely noticeable.
I will try to call the service and ask about this issue. I have a strong feeling that this is a hardware issue. But Besides the screen being defective I also think about the battery. Maybe when in high load (WiFi) it's voltage varies and affects the screen.

It seems if I uncheck Power saving mode in Settings>Display and also uncheck Automatic brightness things improve a bit.

Another issue to worry about .. God starting to think about selling this phone and getting something else. Stuck in a 2 year contract though

some one already reported this on another topic
it does seems that some version of the phone are prone to WiFi interferance
we still haven't found out what causes it exactly
for example i can not replicate the issue on my phone when using WiFi

found it
http://forum.xda-developers.com/showthread.php?t=793944

Cant reproduce it.
Not that I'm unhappy with it...

If this is a hardware issue Samsung should replace my phone. I am waiting though a little bit before calling the service to make sure that it is a hardware problem.
If I find that it can easily be fixed with a software fix, it's not worth the hassle of trying to replace it.

can anyone in North America confirm this issue?
i got a huntch it might be an Europe only issue related to the high voltage of the electric interferance nearby, like lights, tv, radio, wifi, etc.

Well after a long 3 days of waiting i FINALLY got it =)
I plan to test it with the different firmwares of the tab and post up my progress as well as the different plugins since there isn't much online about it.
Well as of other reviews yes it seems like disconnect issues, but only when i turn it on from being off (not standby) it just connects then disconnects but it eventually connects. I've had similiar issues with my headset and my car kit for media both being connected and both would get disconnected so it leads me to more that it is software related than all being hardware.
So far It stays connected, this is only from just having it in the charger and testing.. im running tasker so it will alert me if its disconnected or connected everytime soo.. so far it looks good with the JM6 firmware on the TMOBILE TAB. I will test with the latest firmware after i run all the tests im gonna make a video review with the tab as well.
I really hope this works well because this will be the perfect accessory for keeping the TAB in our pockets while receiving calls and messages.
I'm gonna wait to have it fully charged before doing extensive testing, but i have recieved calls and missed calls and txt messages and it works great as well as a contact call plugin =)
I will also be looking for alternative wrist bands, even though the original one is ok its only slightly uncomfortable because it is somewhat elastic.
12-10-10
Currently uploading 3 videos of my initial review of the first day of use, as well as a video of the custom wrist band i had put on to replace the wrist strap it originally came with, the videos are gonna take a few hours to upload since there 1080p and about 2gb's a piece and this is the second time since the first time failed uploading at some point so hopefully it will get uploaded fully or else i will have to reconvert the vids to 720p and try again later but for now here are pics of the new wrist strap i put on.
This is a wrist strap i got at a local mall , the strap cost me $35 installed and its a 24mm band but trimmed at the mounting points to 20mm to fit on liveview's wrist strap mount, there is a issue though doing this will expose the back and allows the live view to popout of the mount, im looking into how to remedy this by putting some sort of thick fabric or something behind to help prevent it from popping out.
When my videos get uploaded you will see how it pops out.
also in the pictures there is a custom zagg protector put on just the other day , got it for free so its a crappy job by zagg lol. Can't complain for free.

12-13-10 - RECONNECTION FIX TEST'S
Sooooo good news after having some issues here and there really not as bad as others with other android phones, I may have found a solution to fixing the reconnection issues, I rarely get disconnected, so I'm unsure if this fixes that issue, but the problematic issue I had was reconnecting from the liveview being off or when my bt was off as well as being disconnected, but I found a way and still testing to make sure its a viable solution to fixing the reconnection issues.
Ironically I waited the whole day waiting for a disconnect after trying the fix the first time and it seemed to work so just need further testing
12-20-10 - RAIN TEST
So a test i wasn't intending doing, happened..
Its been raining a lot in california and i was rushing it outside to get into the car and as soon as i was inside i noticed my liveview had popped out of my watch mount.. i search everywhere in the car and decide to go look out side in the rain.. well
it was in a puddle =\ fully soaked in water..
i grab it run into the car, the screen still works fine doesn't seem like theres water inside maybe a lil but it wouldn't connect to my tab. So i turn on the heater and put it on the vents and leave it there for about 10mins or so, as i do this i keep checking and still not connecting tried doing my fix for reconnection and no luck as well as restarting the tab..
Well finnally after doing my fix one last time i was able to connect, ironically the liveview was pretty hot but the screen was fine no water or anything.. so i guess the liveview can handle some rain even a puddle .. few..
Video of my reconnection fix up this week.. sorry holiday delays.
12-23-10
So i figured out how to keep the watch from popping off i'm going to post a video of what to do but basically what i did was use a piece of clear scotch tape and ran it through the opposite side of the usb charge port on the band (harder since the band can't be easily removed with how tight its attached to my watch mount) and just left enough tape to put on the live views side and some on the bottom so now the tape acts like a hinge so when i need to charge it i just lift it up without removing it from the band and i can charge it and NEVER have to worry about it popping off anymore =)

Thanks man, look forward to the updates as I'm interested in one of these too. Currently on sale at play.com in the UK for £50

UPLOADING VIDEOS NOW daym 3 parts 2gb's a piece gonna take a while to process lol.
and i did find a wrist strap that works great on the LiveView, it uses 20mm standard strait end bands, i was able to get a shop to use 24mm rubber straps and trimmed the mounting points to fit 20mm so the strap looks wider and looks great with the liveview's wristband mount.
i will have pics up later on as well as u can see the wrist band on the videos when there uploaded.

Cheers look forward to it, also will want some decent alternative straps too. My watch battery just died and it'll cost as much to send off and have done professionally (otherwise will lose water resistance in a regular shop) than to buy the LiveView for now!

Hi hope you can solve a issue. I also want use my Lv connected and working with my Samsung Tab.
I hope you can help me
thanks in advance

I am also interested in the Sony Ericsson LiveView to use with my Galaxy Tab. But did not find many information about it and especially in combination with the Galaxy Tab.
I am very interested in your findings!

UPDATED FIRST POST
still uploading the videos but updated with pics of the wrist straps if anybody has questions or would like me to test something pls let me know, i still need to do more tests since its only been a day since i got it to see if this is ok for daily use.

what issues are you having? i know there are common issues with disconnects but from my experience keeping ur memory about 50mb's seem to be working for me, i always use advance task killer and fast reboot pro with the live view and plugins exluded to keep everything in top shape, i will post up the apps im running as well as services in my daily testing.

yup thats the reason i did this, i found one but they only showed a pic of the galaxy tab with it but not actual tests along side it.

UPDATED first post with my the link to the first part of my video review!

A Sony MBW-150 Watch will also work with the Tab, one has to use a software called Openwatch that can be found on the Market.

my issues
Hi nice video (and nice home page in your TAB!!!, is it a wallapear or application?)
I have some issues with my tab as you can read in many blgs on the net.
It seems works well but avery 15-20 minutes ( refreshing time I think) it will crash!!! you can't do nothing... a tab start to vibrate... it is very, very slow.... you can't use task killer (it too slow) and you MUST restart it!!! no alternatives ways!!!
reading an blog we are waiting some patch from SE... maybe.
Mow I use a LV just like a clock!!!
Any idea? ( i will waiting your video)

Thx, the homescreen is just launcher pro with a simple background and i just have different widgets for easy access i tend to clutter my screens a lot so i can get to things with a single press.
I really recommend to check what apps you have running in the background and see if it runs better with certain apps uninstalled or forced closed, i know there is a issue with sony ericssons part but with my recent tests i do have disconnect issues even with freed memory but not as much as when i run out of memory so when i leave it sitting alone i don't get disconnect issues for a few hours , it seems ok to me for now until i run into a time when i need to know whos calling and its disconnected and i have to pull out the tab.. i'm hoping thats not gonna happen but time will tell and further testing.. i really feel that the sony liveview app is to blame for a lot of the issues.
seriously check on the app "quick reboot" try the free version and see what happens the pro one i paid for so i could exclude the live view and its plugins from restarting, but when live view is acting up i use the free version that will restart all the apps right away.. so two icons on my screen to easily remedy the connection issues. I will still have to run tests to see if i can recreate the problems and fixes.

any idea?

Where did you find the "phone connected/disconnected" audio file?

anyone knows how to find a screen protector for live view?

[Q] HDMI problem in CM10?

I'm absolutely delighted with the smoothness and functionality of CM10 as of now. Obviously I've been experiencing the usual problems of immense battery drain and call quality, but I'm sure those will be fixed in the short run.
However, another problem I think that is overshadowed by all the other problems is the HDMI. This is probably because barely any people actually utilise it on a regular basis, but some people do.
The phone connects to the TV and projects the image fine. However, it is ALWAYS shown rotated 90 degrees so that the projected image on the TV is always horizontal. This is quite frustrating when I'm trying to watch downloaded TV shows. I've tried disabling the rotation in settings completely; however, no matter what I do the moment i connect the HDMI and then turn my phone on, the image is always portrait and rotated.
Maybe time will fix this. However, I wanted to post this because I was afraid that this problem would be easily overlooked and never fixed.
Thanks!

It was said multiple times. Do not mind, that if yopu create thread for thios bug it will be fixed.
Cheers

Thread Closed, please use the CM10 thread to ask and search for bugs.
Thanks

[Q] Video Playback Issue

Hey guys, need a bit of help...
Been using the Z a few days now, and I'm having 2 issues...
WiFi and Bluetooth won't work together at the same time, one knocks the other off whenever I'm browsing and listening to music on my Bluetooth stereo... In the ratio of about 5:1 for WiFi:Bluetooth like...
That's one issue that's a little annoying.
Another is that video playback over WiFi is broken... If I load up a video on the YouTube app, depending on video length, the video normally freezes around the 40 second mark. If I load a video up in my browser, more of the video will load, but never the full video, could freeze 3 minutes in, 5 seconds in, but never fails to freeze.
I've reverted to stock YouTube app, cleared cache, didn't solve a sausage.
I haven't gotten to the end of a single video since I bought the device.
EDIT: Above issue is most likelyan android wide YouTube issue, if the comments on Play are anything to go by.
And that's on top of the Bluetooth/WiFi clashing that I mentioned above.
Not what I expect from a quad core device with 2GB ram like! Any ideas? Faulty handset? Factory reset? Return the handset? I've never rooted or used custom firmware ;so don't really know how to go about it, open to any suggestions to get the best out of the hardware...
Thanks in advance guys.

WiFi/Bluetooth issue
Seems the YouTube issue is an android wide issue, sorry for bringing it up.
Just leaves the Bluetooth/WiFi clashing issue where they keep knocking each other off while they're both being used.

[Q] What would make Google Cardboard rotate constantly?

I picked up a Google Cardboard for some fun, but the picture constantly rotates while trying to use it on my XZ. The axis of the rotation is that of going from portrait to landscape (Y axis??)
I've tested the accel, compass, and gyro using the service tests and they all seem to be fine. My XZ is completely stock and up-to-date (OTA).
Not sure what the problem could be? It works fine on my SGS5. I'd appreciate any feedback as the XZ looks and fits inside SO much cleaner than the SGS5, plus its not my daily driver so I won't have to take it out often.
I vaguely recall the same error happening on an app a long time ago, can't remember for the life of me what it was.

Hey. I also play with VR for almost month now(got two vr goggles with are WAY better lenses and quality than cardboard)
And also I have this problem of rotating screen. And to be honest its all depend on app and orientation provider. Most of the time app use indirect/direct sensor fusion but this method just suck...
I found only one solution for that and its to put phone on flat surface for few second with screen face up, and then phone calibrate sensor itself.
Of course its not helping for too long, but its always something...
My favorite VR game: Corridoom is best example for problem that we have.
Fast movement of device constantly move gyro starting point to one direction and when you sit in chair and look straight after a while you need to almost turn 180* because device lost this starting point. App does provide only simple calibration in main menu and Dev that I write about that said that for now its not gonna change this option.
So even if gyro in our xz is really accurate, because i use it as a VR goggles for PC gaming thanks to app Trinus VR
Only real solution for that is actual app that have option to block or reset roll effect. For example my main movie app for watching VR movies Cardboard Theater have such option and for most of time I dont have this problem when I watch movies.
I also tested it via service tests and you can see this problem, when you start app and this Rubik's cube is faced to you green move phone right and left and after few moves its not facing green, but red or blue... And for that app should have that option to reset yaw and roll when you stop moving, but for now most of devs that create VR apps and games just dont think to put such options.
And its not only XZ problem I tested it with galaxy S5 and galaxy Grand Prime and its also have that problem but not that often, mostly when I move my head very fast or for too long, screen start rotating.
maybe it would be possible to fix that in device it self to reset that roll effect but I dont think that anyone with knowledge would like to check that... :/

Trackers are pretty sensitive without some kind of reference point such as a camera. I expect a small amount of bias error over a duration, but using cardboard movie theater the screen turns 180 degrees (roll) in less than 10 seconds. The sensor tests are nowhere near as inaccurate.
Obviously any phone will have the issue over time though, they are cheap parts in small housing. There's multi thousand dollar systems with small degree of wander that are only IMUs. It's the severe amount the xz has that bugs me.
I'll try the laying it flat so it can reset its bias, might work. I noticed yesterday that when facing west it wasnt half as bad.
If you were actually able to enjoy a movie without locking the orientation then yours is far better than mine. My sgs5 I might have to adjust the orientation once every 30 minutes, the xz I have to reset it every seconds lmao.
Thank you for the input!
update:
Letting the bias adjust helped immensely. Thanks for the advice!

Hi did u manage to sort it out. I have xperia z and have same problem. I can play some games but everytime i use 'view in cardboard ' on youtube the screens spin, also when i use googke cardboard apps. Maby its a google problem and not our phones? Like you iv testedband recalibrated my phone byt to no avail
If you got it fixed giz a shout mate
Cheers
