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.
Hello, I bought the Xperia Z1 3 days ago and I've using it ever since, but I've noticied a bit of a flicker as if the refresh rate is too low, it becomes so apparent at gray coloured areas of the screen, but what's confusing me is that it doesn't happen all the time and that it only happens when I turn the data on and sometimes it doesn't flicker but when it flickers the data is definitely on, I've updated it to 4.4.4 in hopes thats a software issue but the problem still persist.
I don't think it's a hardware issue as it doesn't happen all the time and it's always related to data being on, any advice on how to fix this?
Help please, Thanks in advance
Update 1: I noticed that the screen only flickers when the data is GSM only (2G), But when I turn it to WCDMA only (3G) the screen doesn't flicker!

Hello all,
After 2 week I bought my G800H, the GPS star to take too long to get GPS Signal. Some times more than 10 minutes
Even with 3G (H+) working well and the configuration in "High accuracy".
Other thing that happens is the GPS notification keeps blinking even when no app running.
Anyone with the same problem?
Thanks and B.R.
I have the same problem. Didnt find any solutions yet. Reboot, apps, settings. For me i could be the OS or the sensor. I have a S3 Mini and the gps signal works as a beauty!!!!

Happened to me also few times, but it happens only when I try to use GPS in car. Outside it works without any problems and gets lock within a minute.
Sometimes in car it gets lock and then looses it after few seconds and has to reacquire it again, which takes few minutes.
Maybe there is some interference?
i've similar issue with my sm-g800 f with 3g connection disabled (ten minutes to fix), when i enable connectionless tha n 1 minute.
I my case problem is wrong server in gps conf file (north america server), but i'am in europe. I dont' know any method without root device to fix it
(changing server with right one, and reset agps data with gps test is the ony way to fix i know)
I have narrowed down my problem to Sygic BlackBox.
If I disable this addon, GPS works correctly and is able to fix quickly. When enabled, I experience poor quality of signal for the first 10-15 minutes, even with data enabled.
Create an issue with sygic, hopefully they will have some tips for me
Today I was experiencing GPS issues again but unfortunately it was not related to sygic.
I have searched around internet a found a bunch of people complaining about GPS signal on S5 mini (both single and dual sim).
Reset of AGPS data and restart helped, but that's not really useful.
Anyone else here experiencing weak GPS signal? I will try to ping Samsung support on Monday...
Here the same problem. G800h mini on my s5. poor gps fix and very inaccurate. I flashed to firmware G800HXXU1ANK2_G800HXEO1ANL1_G800HXXU1ANK2_HOME.
Anyone a solution?

Hi! Same problem on my S5 mini duos using MAPS ou WAZE. Any news about a solution?
It seems to be fixed for me, at least last 3 days I didn't have problems and I was able to navigate with sygic without any issues (2x 150km trips).
I tried GPS Status application and that was not able to get signal also, so I have tried to do factory reset, whether this is software related problem, but that did not help either.
So I though it might be some issue with antenna and connection to motherboard. But S5 mini does not have any bolts or anything like that, everything holds together by strong adhesive.
So I decided to heat the back side around GPS antenna (left upper corner if you are looking at the back of cell phone) with hair drier and push it hard inside when it was warm.
After that I have tried GPS Status application and it locked in 21 seconds and was able to lock on 15 satellites (Before I didn't get more then one or two satellite after 15 minutes even with data enabled).
Don't know if it will help anyone else, but might be worth a try.
that sounds interesting.
Guys, any news ou resolution about this issue? I bought mine few weeks ago and the GPS is the worst i' ever had! I can't use WAZE ou GMAPS properly because of this!!! First time this is happening to me....

i could fix my wifes s5 mini too with the hairdryer, thx for the idea :good:
1. remove backcover, lay it flat on a towel (face down)
2. heaten up the upper left corner (backside) as described above,
3. then push it hard down for about 5 minutes til cooldown to be sure it is fixed in position
4. profit
:laugh:
edit: before the procedure the phone received 4 to 5 weak satellites in gps test, now the phone receive 16 satellites after 10 seconds.
Glad to hear it helped to someone else also.
I know it sounds stupid but works
@dawaldi Please can you portray a picture of it?

Here is picture of the phone with the back cover opened up, there are some kind of springs and glue inside the "doors"
Personally I have pushed down both side, just to be sure.
thank you! Today I had tested on my phone. Heated with a hair dryer and then the finger pressure on the body. It is better but the pressure is not sufficient permanent.
I will test tomorrow.

Here too!
I have had the Z3C for about a week. I am really happy with most things but a couple of things are really poor.
1: The camera performance is really bad. Even in pretty bright conditions, the pictures look dull, washed out and pretty grainy! My old Razr i took better pictures!
2: I am on the Three Network, and for some reason, Data Connection only works if I have 4G enabled! Surely it should work on 3G too. I keep 4G off otherwise the ads eat up all my data allowance as they load so quickly!
Anyone else having these problems... Its the camera that the biggest dissapointment. What am I doing wrong. I have tried manual as well as Auto mode... Bumped up the resolution to 20M... and the results are still poor.
Maybe post some poor results. I have to say, mine is pretty solid considering it's only a phone.
And i'm also using Camera FV-5, which will show a huge difference once Android 5.0 RAW DNG drops.
Try other apps like Google camera. The results will be more consistent. It's mainly the stock app that sucks.
To me it seems that camera performance is the worst if you shoot towards the light source like the sun. They turn out washed out then, like I have a greasy layer over the camera glass. But otherwise, i'm amazed by camera, especially macro shots.
For some reason it keeps dropping the data connection. If I flick 4G off in the settings I get no data connection. When I flick it back to 4G the connection re-instates for a period of time before being lost again. It seems that when the signal/connection is lost, it does not get re-established once the signal returns! I have to manually flick it to 3G and back to 4G to wake it up or go to Airplane mode and back out! How stupid is that. I read on the net that it has something to do with the Three Network. Anyone else suffering with this....
Just seem to have problem after problem with this phone... I'm thinking of just returning it and forgetting about it totally!

Orange Slovakia as the operator here, using Generic Central Europe Z3C and no issues with 4G like the one you described. I have a strong feeling that this has to do something with the network rather than the device.
I have just got Verizon LG G2 32gb.. and I am facing severe reception problem. Previous i was using Sony Xperia L and in the same room, it was catching the full signals while this LG G2 is not even getting any reception.
Any solution ?
I have tried changing the settings from Global to GSM but didn't work..
Please if there is any suggestion then guide me..
+1 im also having the poor reception
Same here. I have do to get back my signal a lil quicker is turn on/off airplane mode. Its not a solution but it helps me a lil.

but it wont be helpful for longer because soon the signals will drop too.. so how many times airplane mode has to be enable/disable again n again :/
its very annoying problem
I have serious signal issues as well, Motorola's seem to have a better reputation with reception thinking of trying a Moto X?
