[HELP] Problem with color - Samsung Galaxy Core

Hello,
I have a problem with my phone. Sometimes, when I unlock my mobilephone the color of screen fades. I need to lock and unlock mobile to restore in normal color. I sent my mobilephone in service. The first time they changed the screen and format it. The second time tested it for two days but they didn't t find any problems. Is there a problem with Rom (Original ROM of Romania)? The mobile phone has never been rooted. I try to use it in safe mode and I have the same problem. What's wrong? Can you help me?

Same here but it happens only 1 out of 80 times so i guess it's not a big issue. It happens just after pressing the power button (before unlocking)
I though that i was the only one getting this error. But i got company. jus' kidding! Taking it to the service centre would probably fix it.

Hello my friend,
Thanks very much from your answer. Yes, it happens just after pressing the power button. I sent my phone in service twice but nothing change. I called Samsung and I told my problem but nothing again. They told me to send it again in service. I am very disappointed and I don't know what to do. Moreover, one friend have the same problem.

Must be that core if born with this defect.
Let's see what other members of this forum say. :laugh:

That mean that mobilephone have a problem in hardware? Why service can't find the problem? It is very irritating!!

Although d colour problem won't be fixed bt cyanogenmod definitely will improve d performance. My dad has s advance and he found great improvement in performance after installing cyanogenmod!

I don't have any issues with my Core.
It works smoothly..

I have this problem too! But it appears less than once in a week. And I noticed it only happens right after heavy usage, like after I play online games, and lock it, the screen color fades. Samsung won't even bother on fixing this type of small issues, even though they have tons of heavy issues to fix too!

Have you tried flashing it with amother firmware? I suggest you should bring it to the service center so they can take a look. By tge looks of it, it may be a harware problem.

It's definitley a hardware fault. Just to make sure, bring it to the service center to have it checked. Yours have the same symptom as my sister's phone.

This had happened with my previous phone - moto milestone. Replaced screen twice, and the problem happened again. Sold it off and bought my i9003.
I think it is due to electrostatic charge building up on your body that affects the electronics. That is my (unproven, unscientific) theory.
I'd recommended you get it fixed and immediately exchange it at your dealership for another phone. Peace of mind that way.

So many errors...

Hello im Andy from Austria
I got this phone now since 1 month and its my first
android phone. But i have to say that this is not the phone i expected... It all started when i got the first deep sleep on FIRST day. I thought it would go away after some time but it didnt stop. Then i read this things about flashing etc. I tried flashing many firmwares, custom ROMS and kernels... Nothing helped against the deep sleep.But this is not the only Bug the phone has. Sometimes when i want to call someone i cant hear anything. I have to call like 3-4 times to get it work (very annoying). Sometimes i cant do anything (freeze) , 3g doesnt work , cant boot without putting battery out and in again and even more things. No wonder why the phone got out of stores. Currently im on NeoRom 1.0 . But i read some posts where people got their phone dead randomly, and so i want to revert to default config like i got it from shop. The problem is my binary counter is currently on 4... Is there any method to get it to zero without paying? And another problem is maybe because i have removed simlock from it so i think warranty is gone anyway...
Maybe i try to completly reset the phone and then sell it to someome to get some other phone...
We also dont have any CM and i wonder about this because many unknown phones do have CM... Like Galaxy Y or etc...
It would be better to get some GS2 or GS3.
At least there are no deep sleep issues.

First of all:
Deep sleep is not an issue! It's a good thing, it's the state when your CPU rests and save your battery. The problem you mentioned is called "sleep of death" (when device becomes unresponsive after screen off)
You can reset your counter with USB-jig (if you have Odin protocol v. 2, if you have 2.1 it's a way more complicated))
It sounds stupid.....but did you change the WiFi sleep policy to never ?

My SGR touch was also not responsive, installed stock rom and took it to service. Now working fine.
So there are galaxy rs that work fine?!
Some said it needs new motherboard. How can i check if i really got a screwed phone?

I agree with pudup . You should visit your service, and explain to them your problem, but even this does not guarantee that you'll get a replacement of motherboard. Maybe you can ask for refund than
i think in austria there isnt even a SSC.. :'(

Crazy Backbutton

Hello,
my Backbutton activates itself. While I am watching Videos, or whatever I do it stops shining and I am out of every application I'm using. After about half a minute it's shining again and I can use it normally. It's like pushing the button multiple times. Does anyone has an idea how to fix it? I tried different roms but it looks like an hardware failure to me.

Happened to me as well it is an issue sometimes with samsung but covered under warranty bring it in to sprint
Hit the thanks button if i helped
Sending it back for support is not an option for me. I imported my device from the US to Germany. The support at Samsung Germany told me that they are not responsible for AMOLED devices.
My second problem ist that my IMEI is crashed since I flashed a rom where the dev made a little mistake. So Samsung won't give me any support.
I thought about changing the display but the price for a new one is about 190 Euro. Way too much... I can assemble and disassemble the device but I think that cleaning the device will not solve the problem.
Any suggestions?

It has nothing to do with the display though.
That's likely the part failing:

Verify that the one you currently have isn't simply not connected right.
Thank you. I will have a look if the part is not right connected.
Maybe I have to replace it. But in that case 25 Euro are much cheaper than 190.

This happened to me once. A day later my display completely died. I could turn on my phone, answer calls, etc the touchscreen worked, but I couldnt see anything. I had to get a new one..
I had this problem too.
I flashed a different radio, and boom!! issue resolved
I occasionally get this too. It only comes up when I'm using cm/cm based kernels though, very odd. I'm on matrix right now and it seems to Beowulf, anybody have some tips or suggestions?

I tried a different kernel and it looks like the problem is solved. I know that you should not count your chickens before they are hatched. But I really think that the kernel was the problem.
Anyway, I am just happy that my phone is working properly.
And now I am waiting for jellybean.

I don't see how the kernel would have anything to do with the backbutton. Although if it worked out then hey that's awesome. Amazing how much I have learned by reading the forums on this site.:victory:
Just clean off the the backbutton, and maybe it will stop or you have a software bug.

Had the same problem. Go to setting-battery and see if Android OS drains more then 50%. If it does one of your applications is responsible for that. Fastest way to solve problem is to reflash stock rom, you have tutorial on this forum how to do that.

It happens to me too alot of times.. It happens when apps consume too much of power. Try disabling some of the rarely used apps with greenify

It's clearly a software issue. Reflash might help.
