To take a screen shot with your galaxy s phone. hold down the back button and click the power button once. I couldn't do this before I updated my phone. so if this doesn't help you take it in and update your phone.

You can take your galaxy S 3 phone to the manufactures if you want its screen replaced.
Take it to a repair shop. The screen is probably damaged and needs to be replaced.

You can send your Samsung galaxy S 4 back to the manufactures for cracked screen fix.

Screen size seems to be important. The G2X has a 4.3 inch screen, bigger than the first Galaxy S 4G. However, the new Galaxy S II 4G has a 4.5 inch screen and a faster processer than the G2X.
oye
Samsung Galaxy S is better. Galaxy Ace has a smaller screen. But if you can't afford Galaxy S, Ace is also cheaper. In fact, Galaxy S2 is the best among all.
press the middle button and the lock button at the same time :)
Yes, scientists can look at space and take pictures of it.. the first time this happened was in the mid 1960's when the voyager was launched. It sent back picture's of space to Earth.. almost half a century later it has final reached the edges of our milky way and take pictures of beyond.
Your screen mirroring is probably toggled on. Go to the Galaxy S5's quick settings, tap the Screen mirroring icon to disable it and that should work.
The Galaxy S II is a great phone for taking pictures and uploading them. It has excellent picture quality and pictures can be easily uploaded to most social media sites within a few seconds.
