I just got my tab yesterday and i'm wondering if my specific one has a problem or if this is a known problem. The brightness level of the screen changes spontaneously. Sometimes its while i'm reading a page but other times it's when im moving between pages on the internet but it doesnt seem to bounce back to the level i've set. I turned it off auto-detect brightness but no change.
Help is appreciated. Thanks.

I've been getting this too. I think you have to be careful not to cover the sensor with a finger, otherwise it thinks it's dark and dims the screen. But it does also respond too slowly when you uncover it again.I'm also not quite sure exactly where the sensor is.

The sensor is the front facing camera. The auto setting became too much of a bother so I switched to manual. If you turn off the auto mode brightness should not change by itself.

In Settings/Display settings/Brightness. Un-tick Automatic and turn brightness up full.
Also in there is a Power saving mode which I always have checked.

Go look for the widget BatteryLife V1.3.3 and install it. You will then have a constant check on your home page of not only the % remaining, but underneath that an indication of the health of the battery.

If it's anything other than "good" then I would refer your Tab back to your Supplier.

Do you mean power saving mode unchecked? as soon as I check it it dims. I did everything you suggested.

Ok, once I figured out what a widget was...::sigh:: and found it ::double sigh:: (big learning curve here) I installed it. Says battery's good.

Now, how do I unstall the other widgets I accidentally put on the page in the process?

If I'm looking at the wallpaper and it's bright, as soon as I hit browser the brightness dims and it remains that way. Does that happen normally? I don't mind taking it back to the store and asking for another - I just don't want to look like an idiot if this is standard. However, if this is standard, I don't like it at all and might not keep it. And that would be a shame because it really is fun.

1) No I said my savings mode was checked.

2) To un-install anything other than a core program, go to Settings/Applications/Manage Applications.......select the Application you want to un-install, and on the alert screen select Uninstall.

3) It is not standard for the brightness to dim when entering a browser from your home page, but for the life of me, I can't say if this is because of an internal setting, or a fault with your Tab. The idea of installing a battery widget was purely to get an idea of the health of your battery.

Perhaps other Members can chip in here with a possible solution, just in case there is something obvious that has been missed......

I think the power savings, as it says, responds to screen content by adjusting the brightness. So, if checked, the brightness changes.

I was having the same issue with my new toy as well. I just unticked the "Auto" next to the brightness slider from the pull down from the top of the screen and all is sorted now.

I had to sign in and post since i've encountered the same problem with my new Tab. The solution is to open your broswer and then select the "menu" button on the device. It will give you a list of options, one of them is to adjust the browser brightness. I have no idea why some idiot at samsung decided the browser needed its own adjustment...

If you haven't already done this, then try this.

1. Slide down the notification bar which is at the top of the screen.
Then untick "Auto" at the Brightness line.

2. As mentioned earlier, if you are using the standard Android browser, then you need to select the
Menu button, Settings, Brightness. Adjust it to your liking. Alternatively, get Dolphin Browser HD or Opera Mobile.


I hope this helps. The auto dimming is because of the auto function. If it still dims, then maybe
check with the vendor.

Ah! Thanks! This has been driving me nuts for a week now! I whole-heartedly agree! Browsers with power saving features? Geeze.
