Samsung's Dimise

Posted: Jan 31, 2013, 10:08 AM

Phone owned for more than a year

Well this is a good phone for what it is. It is by no means the golden child of Samsung. And I am surprised, because Samsung usually pops out some great phones. Usually if it's not Samsung or LG I wont buy it.

But I guess everyone is entitled to a few fails. This one though it can be inconvenient when it fails. "HEY! LET ME SHOW YOU SOMETHING ON FACEBOOK!" *phone freezes* It does the same thing when I go to my photo gallery.

But in the end the phone works for what is needed- calls, and sometimes text. I say "sometimes text" because when the phone decides to act up I could be writing out a text and it deletes the text and goes back to the message inbox which is highly annoying.

If I am ever to get another SideKick, it will have to have GOOOOOOOOD reviews, the fact that it was a Samsung, I just decided to not take a second look at it, and buy it. That was a mistake...

STAY AWAY BAD PHONE!!

Phone owned for less than a year

looks like a very good phone but when you start to use it then it doesnt work very well at ALL!
I am a very heavy texter, im a teenager. I dont recommend this phone to anyone! I have replaced the battery, the phone, and downloaded apps to help NOTHING WORKS. it doesnt even last through school and i dont text a lot at school. I turn it off and i send one text and its pratically dead when i turn it back on and after i text a couple times. As for the pros though the camera is amazing but i hate that there is no zoom and flash. the front camera is really good. the music player is good too, but if your a heavy texter like me, dont buy this phone!

I am on my 5 phone due to bugs in the system. My phone will turn itself off and do a partial restart, which just messes everything up. It will osolate like talking into a fan. when I have had to get support for it, they had to find someone who knew anything about them. I got one because my mom has one. She has had nothing but trouble with hers as well. Stay away from this phone. I would rather go back to a "dumb" phone than forced to use this phone.
