[Galaxy S6 General] Truestark:
Why am I starting this thread?

- To make a proper issue thread, most users are reporting issues on various threads.

- If someone is to buy a S6, or has got a new one, they can resort to this thread for checking their handsets.

- Issues can me major and minor, and considering we have paid a fat buck, we cant settle for less.

CAUTION:

- read this thread only if you want info about your device and for cross checking.

- Once you know your device has any of the below issues, it will bug you forever!! so dont blame me, I'm just trying to be informative.

1 ) Uneven screen, Uneven brightness, Uneven color, Gradient on grays, Pink/Yellow tints:

Common issue with amoleds, Amoleds are manufactured by deposition of various layers on a Substrate (Glass, plastic). Then these layers are exposed to light in a procedure called as "Fine metal masking" . During this process light gets unevenly distributed across the big plate of glass from which our displays are cut. Why does this happen? The technology isnt as mature yet, earlier in 2010, it was worse, now it has improved but not perfect. Due to uneven exposure of light while manufacturing, some parts of the mother-plate do not get equal light and hence we get tints, gradients on grays, and uneven whites (pink tints). The more your display is cut from the center of the plate, the better is the accuracy, the more it is cut from the sides, we get uneven tints.

Here are some images:

What can you do about this? will this be fixed in a software update?

- NO, no update can fix it.

- only a screen replacement, or a RMA can.

- Replace your device if you cannot stand the tint, or if its bothering you (After all you have paid a lot for it)

- EVERY Amoled will suffer from this issue, ranging from negligible, to intolerable.

The note 3, S4 and Nexus 6 are affected by this issue majorly. Many live with it, some go for replacements and end up in a cycle of RMA's. If your display is tolerable or if it does not affect you, then dont go for a replacement.

2) Color shift at various angles

The display is glass, and it will show some rainbowing to an extent. Color shifts on pure whites are noticable . This does not mean your display is defective, it is just the way it is.

3) Auto-Brightness not working

The S6 shuts down brightness settings at low power to save battery. Make sure you're charged. Still if it does not work properly, check if you have any screen protector or tempered glass covering the ambient light sensor beside the earpiece. To cross check if your ambient light sensor is working properly, use CPU Z, go into the sensors tab and check for the light sensitivity, it should range from 0 to 30 or even more at brighter lights. if it is showing less value or no value, your sensor is not working. Get your device replaced or serviced.

4) Lines on display

Here's something new that I noticed today. If you subject your phone to direct sunlight, and full brightness, there are clear visible lines on the display. It is a manufacturing thing and it does not bother me. I do not use my phone is sunlight. I could not get a good picture, so I drew it in paint to show what it looks like.

Here's a picture:

I dont know how widespread this issue is, but its there on mine, clearly visible on lighter colors like (cyan, yellow) ONLY in direct sunlight. As it is not reducing my usability to any extent, I am not replacing or getting my screen serviced.

These markings look like some techie circuit lines. No display is perfect, there ought to be some or the other thing on it.

5) Flash always lit

This is a well known issue, as of now we cannot do anything about it. Even when the phone is switched off, the flash is on dimly. My guess is, it is the way it is, there is no current leaking into it as the phone removes current from the Motherboard when switched off. So this looks like the flash is manufactured like that, maybe some glowing material like phosphorous, (IDK). The flash otherwise works just fine. To see the issue, go into a dark room and observe the flash area, you will see a faint glow. Here is a picture by tenxo

6) Phone heating up

The phone will heat up on heavy use, it is very common on androids. I did not even needed to mention this issue as its not an issue. I read some people complaining, so I included this.

Androids will heat up. you cannot do anything about it. My Galaxy S3 and Nexus 6 used to heat like a frying pan (45 deg to 49 deg). Even my S6 heats up so much on heavy use, or while the Wifi Hotspot is on. (Lol. Hotspot). Anything above 60 deg is not normal. I have never experienced it, even on over clocking the CPU on my previous phone. The fast adaptive charger will heat the phone up, and it is normal.

7) Regional Locks:

Say, you have brought a S6 which is for some other country. There is a thing called regional locks, wherein you need to activate the phone using the same country sim. Idk why samsung has done this, but it is regionally restricted for activation. Once you have activated the phone, you most probably should be able to use it anywhere else. (Cant say as I havent tested it). How to remove regional lock? No info that I know of in that particular matter. If anyone has anything to share on this subject, please leave a comment as it will be helpful to others.

8) Heart Rate sensor always on?

Uninstall google fit, reboot the phone. Samsung health app has some problem with google fit. Uninstall google fit, and everything will be fine.

9) Capacitive keys always on?

10) High RAM Usage.

Apparently, a common issue. Samsung is really bad when it comes to ram management. It's a known issue that there are memory leaks in lollipop. Luckily software patches will be available soon, try closing all apps or disabling a few Samsung ones which consume ram. For me it is not a big deal as I am not facing any any lag whatsoever in any apps even after such higher ram consumption. The only problem is when apps are switched, the app may force close. Wait for an update, or flash cyanogenmod when it is available. Meanwhile try other stock custom roms in the forum.

Update :

After some minor updates over the last month, I've noticed some improvements in RAM usage. Earlier my ram consumption used to idle around 700mb free, now it's around 1 GB free. I have the same apps, same usage and I've installed more apps over time and still it has got better.

11. Uneven capacitive buttons:

One xda user reported the button backlit is uneven, I do not use the button backlight, it is always off for me. If you notice this issue please report.

12. Scratches on the screen

Scratches are not common and highly unacceptable. If you're noticing scratched screens, get your device replaced.

If you find this thread informative, or if you want to throw a stone at me for pointing out a flaw in your device, you are welcome to hit the thanks button. I have severe ocd when it comes to my phone, and I cant handle noticable flaws. :D
