Samsung Behold 2 :: Screen - Color Banding - Flickering
Jan 16, 2010
Just wondering if anyone else had noticed faint flickering issues with their Behold 2 screens? I especially notice it with smooth gray scale gradients, soft focus wallpapers, or solid color mid tones. Also, some color banding in grey mid tones... looks like faintly alternating horizontal lines of green and magenta. I work in digital imaging professionally, so I really notice such things. Can't decide if I'm being overly critical, or if my phone has an issue.

Seems my original post ("ugly pngs...") somehow disappeared :( nvm.
I have a problem with a png resource that has gradient fade-out alpha.
The png looks great in the emulator, but displays an artefact known as "color banding" (http://en.wikipedia.org/wiki/Colour_banding)
Has anyone surpassed this issue ?
My designer wants to trop a shadow behind his icons, and that's where the bands appear.
What are my options ?

I have a strange problem with Galaxy S, can somebody please check if they do experience the same thing.
My battery is low (about 13%), I'm connecting SGS through WiFi to the Interent. Any time the device is downloading something: web page, image from Picasa, etc. on the screen appears flickering tiny lines, like magnitic distortion. Once page fully loaded screen become nice and clear. If I plug power, USB, the screen and download happens normally. I tried different setting (brightness of screen, vibration on/off, stay away from electronic devices)

I can't seem to completely figure out how to change the color. I found a status_bar.xml in the framework-res.apk but am at a loss as to how I can edit it. Someone want to give me a nudge in the right direction?

Tried rooting so I started off flashing r8 of bh_man's 1.6 rom. Went through the setup, odin turned blue to pass and I let the phone run past the android system and then the screen turned off.
Thing about it is that the phone is still being detected by the computer and odin. It's like my phone is on a screen lock but not responding to when I push unlock.
Ive tried every custom rom and each one does the same. I try to go back to stock and most of the time the program closes, when it doesn't I try to flash it and it goes through the process but goes on forever. One time I let the timer go on for 2 hours and it was still on 5/9 completed.

I'm using GLSurfaceView to create a simple OpenGL drawing application. Since the elements drawn in each frame must remain on screen in order to be composed into the whole drawing, I don't use gl.glClear(GL10.GL_COLOR_BUFFER_BIT) at the beginning of each frame. But not clearing the color buffer leads to substantial flickering. Is there any way to eliminate flickering while still not clearing the screen at the beginning of each frame?

Had my desire on charge last night as usual, woke up in middle of the night, hit the button on the top of the desire so i could see the time, but rather than the screen lock appearing my homepage appeared but it was rapidly flashing between that and a white screen and was unresponsive. I have the spinning earth and moon live wallpaper for weeks now and the moon was moving back and forth a tiny amount much like when you press pause on an old VCR.
After a few seconds swiping with my finger it eventually responded and the flickering went but came back when i swiped screens once more. i unplugged it from the charger and it did it again.
I then took the battery out and put it back in and since then it seems to be working normally. I also noted that the clock had been frozen at 00.15, when i resolved the prob it jumped to the true time of 03.30. 00.15 was probably about the time i put it on charge so has plugging it in caused it to lock up?

I was using the camera this morning and after a few seconds the screen started flickering, it then turned a shade of purple and the view split so the bottom of the picture appeared at the top. I rebooted the phone and it was fine for about 30 seconds and then did the same. Second reboot and it appears to be ok. Just wondering if anyone else has had this issue? All software is as standard the phone has not been rooted (yet).

I bought my Droid 2 last week, after trading it in from an LG Ally. It's quite awesome! But little droidy is sick ): The screen is constantly banding and flickering, sometimes at different strengths. At points it's hard to look at the screen and hurts your eyes. I heard this happened with the Droid X's as well. Sadly, the day after I got my Droid 2, my 30-days (I got it at best buy) to exchange the phone ran up :<
Is there anything I can do so they can exchange this? They sold me a defective product for $200! D: I think they should listen and give me a working model.

My device is a local re-branded and enhanced Xolo a500s/it's like a karbon a5 a think. After successfully updated my device via OTA and after my device rebooted. My screen started to flicker randomly. My phone is not rooted and im still using the official stock rom. I found a temporarily solution by doing a Factory Reset, the flickering would be gone but it will come back after my phone screen goes off and on.
I suspect that the new lockscreen bloatware system app that comes with the update causes this, I can't disable it(googled already, and the only way to freeze/remove it is to root.) I can't root my device for something like a hunch. I'm waiting for a software update that would fix my device's touchscreen collide bug.

My Screen flickers slightly on the home screen. When I use 2g data it flickers alot and is really noticeable. Has anyone else experienced this problem with their Galaxy? Is it a software or hardware issue. Its like horizontal lines are going down the screen. Really annoying.

Has anyone else noticed some type of faint scrolling lines on their screens. I notice it more when on lighter backgrounds, like the blue ink splash. Both my behold II and a friends has the same thing. Is this a property of OLED screens, some type of refresh? They are horizontal lines and dont always cover the whole screen.I really read how awesome an OLED screen was supposed to be, but eh I think the Iphone screen is still nicer. Any thoughts on these lines, I doubt this is limited to two phones.

Is there any way to turn up the sensitivity on the touch screen?It seems decent enough, but it is no where near as resposive as my old iPhone.Why? It just seems like I have to touch everything on the screen twice.

Ok I first just want to say that this phone is so nice, and I was so scared to get it from everybody on this thread complaining but I don't see why.
-I had no mounting problems.
-Memory is awesome compared to the g1
-I don't see no lag. I think people say this because of the vibrate when touch method samsung has on it.
-I actually like the touchwiz interface over the boring silver android. Messaging is awesome with the picture of the friend you messaging.
-The cube is pointless though, but friends love it.
-It's plastic but it really don't feel cheap at all.
-Battery life isn't too good, but what smartphone battery is? What else do you expect from a phone with that nice of a display screen.
-No reboots
-I haven't had a force close yet, but when I had the g1 i had at least 10 a day.
-Has to be the nicest camera phone since my old n95.
-There was complaints about overlapping objects on the home screen. I love that it can do that.
-My only complaint is the 4 buttons on the home screen. They are just simply pointless.
I feel alot are just being too picky. This has to be the best android phone behind the nexus one. Some questions though...
1.Can the home screen go into landscape mode?
2. Anyway to lower the brightness of the camera flash. It's blinding lol
3.Im trying to install some apps from my g1. (cracked) Most install but some don't. Is this problem because the apps are only for android 1.6 + ?
4. Anyone have any super thin case's? Where did you find them?
5. On the commercial about this phone with the comic artist. He changed the color of the picture with some app. What app is that? Is it pre-installed?
6.Does the phone lag any with a new keyboard installed? I was going to install swype or better keyboard.
7.Is there not any light's to show that the phone is charging, or when you have notifications?
8.This might sound ******ed, but is the screen glass?

So I went to the beach with friends this weekend and had my phone in a ziploc bag along with other items. Well, it seems that one of my friends went into the bag to get something and had their hands completely wet. About one hour later I went to check the time on the phone and there was about two inches of water in it. I immediately removed the battery, SIM card and sd card and left it out to dry.
Got home some time later and did the rice trick and left it there for the entire weekend (just switched its position every 8 hours). Tried to turn it on this morning and it powers up, makes sounds and vibrates but the screen doesn't come on. If I touch the screen in some spots I still get vibration feedback and sounds but nothing else.

Is there any difference between locking the screen (screen being off) and "sleep mode"? If there is, is there a way to force not to go into sleep mode, but have the screen off?

I believe it's called boot looping? It originally happened after I rooted my phone (original 1.5 software) following these directions: How To: Root the Samsung Behold 2 | The Unlockr. After that, I deleted DinerDash2, Midnight Bowling, Where's Waldo, IM, Talk, Amazon MP3, MyFaves, Telenav, HotSpot, Audio Postcard, Postcard.apk. When I tried to reboot my phone, I was stuck on the Samsung screen. I finally got the screen to go away, but a message repeatedly popped up saying the TwLauncher closed unexpectedly. Then I tried using ODIN and installing BH_Man's factory v1.6
http://androidforums.com/all-things-root-behold-2/63612-port-behold-ii-factory-1-6-a.html.
I used the adb commands to delete the bloatware again. Restarted the phone and got the same problem. (Except I was stuck on the android screen.) I tried to install the factory v1.6 again, then immediately did a factory restore and then rebooted my screen once it loaded. Everything seemed okay. I uninstalled the stock games and rebooted again. It seemed to be working. When I uninstalled more apps (including CubeLauncher) and restarted the phone. What do I do? Did I uninstall something I am not supposed to? I think I might try installing the 1.6 No Twiz Kernel. I am sick of these "TwLauncher closed unexpectedly" messages.
