How come when I am in the Gallery and I want to view a landscape photo, when I rotate the phone it doesn't automatically rotate the photo, I have to hit the 'rotate' button in the corner of the screen? Auto rotate is ticked in Settings/My device/Display/ Auto-rotate screen and also when you pull the screen down 'Screen rotation' is on.
Can somebody please help me. Thank you.
the SAR value is different for different location,is it possible...?
i don't think so...
i think, they cheat us..
nish, 15 Sep 2013anyone knows why the phone keeps on restarting?bc this phone is been made it to be oven and oven restart .)))
The phone is really good very powerful I jumped from S3 which was already solid in performance to a real super performance S4, that being said if you want snappy quick then dump Touchwiz for Nova Launcher, HUGE difference and zero lag. .. Nova Launcher should be the default Launcher for all Android phones
Asrarul Haq, 15 Sep 2013All features are rocking. But the battery backup is not good enough. The Actual talk time is 1... moreBATTERY ENDURANCE =69hrs according to gsmarena -very good -better than most
I have a Samsung GT-19505, password protected. If a text message is received, the name of the sender and a part of the message can be seen by others. How can this features be disabled?
All features are rocking. But the battery backup is not good enough. The Actual talk time is 1.5 hours and the approximate standby time is 24 hrs.
note 2 is the best phone made by samsung but for s4 its work better in cold countrys like alaska and eskimo its a oven not a mobile when i use 3g its so hot, i try all phones till now the best 2 phones i found was note 2 and iphone 4s

rsnsvs, 14 Sep 2013I haven't found on my s4. Did any other user found this update????keep checking ota and via kies daily .. google august 2013 update for s4 and you shall find enough news and links ..
rsnsvs, 13 Sep 2013Samsung didn't introduce any update of the phone then how are you getting this update.LAST known official update==19505xxudmh8.. wed august 21
10.57.33 KST 2013.. OTA or via kies ==2 hrs nearly to complete..
Using this phone. everything is fine except the battery. actually android is a laggy os. it always use minimum 700 mb of ram. if all feature is on than the usage of ram is 1.4 gb!! lol. The battery should be 15000 mAh. not joking. my set was stand by. but per hour 2 percent charge is going down. i am doing nothing. Actually this is the fault of android not samsung. At least we need a 3 gb ram and 10k mAh battery. then it will be equal to 2000mAh windows mobile
Chan, 13 Sep 2013S4 1080p PenTile is not true 1080p
https://medium.com/what-i-learned-today/995... more"To get the total pixel count, we divide it by 3, because technically each pixel is made of 3 subpixels. So, 4147200/3 = 1382400."
This statement is incorrect. Each pixel is made up of three sub pixels in a traditional display, but not in a PenTile display. You're forcing it to conform to the standard of a traditional display, even though it's different technology that was designed to have/use less sub pixels.
Technically each pixel in a PenTile display is made up of 2 [unique] sub pixels.
S4 1080p PenTile is not true 1080p
Full HD means 1920 by 1080 and it gives us 2073600 pixels since 1920*1080 = 2073600. On a traditional 1080p RGB panel (like on the HTC One), itís the same but on a Pentile display, things are a bit different. See, each pixel on a RGB panel is made of 3 subpixels. On a PenTile display (like the one on the Galaxy S4), it is made of two and the missing subpixel in each individual pixel can be found in the adjacent pixel, which means on a standard 1080p RGB panel, there are 6220800 subpixels (2073600*3 = 6220800), but on a 1080p PenTile display, itís 4147200. How?
Since 1 subpixel is missing from each pixel, we subtract 2073600, which is the number of missing subpixels on a 1080p Pentile display from 6220800, which is the total number of actual subpixels on a 1080p RGB display and we come up with 4147200. To get the total pixel count, we divide it by 3, because technically each pixel is made of 3 subpixels. So, 4147200/3 = 1382400.
So we now got the actual total pixel count. But how do we convert it to resolution? Itís easy, we divide the horizontal aspect ratio by vertical and then vice versa.
16/9 = 1.77 and 9/16 = 0.56. Then, we multiply each by the total pixel count:
1382400 * 1.77 = 2446848
1382400 * 0.56 = 774144
Then we take a square root of both:
sqrt(2446848) = 1564.24
sqrt(774144) = 879.85
Rounding each number, we come up with 1564 x 880
