Thought it was cool...?

Posted: Nov 13, 2011, 8:32 PM

Phone owned for less than a year

So i got this new phone, i opened the box and i was like "WOW." Thought it was soo cool cause it was windows. But after i messed around it for a couple of days and the worst hit me.

1) Cant recieve or send pictures?
2) The shutter button can not be turned off, even if the phone was on silent (That bugged me) And you cant zoom in while recording a video.
3) Can't add your own ringtones. So your stuck with the ones they give you.
4) the battery cover is soo thin and the color on the cover scratched off on to the case i had for it.
5) No memo area? No note taking? wooow, even my windows 7 laptop can take notes.
6) its a fat phone with not much use, i guess.

The good things were that i liked the keyboard and the messaging. The key board was smooth and spaced out and was easy to use. Atleast it has a calculator and a calendar.

I was dissapointed after trying out the phone and it didnt have much.

Nice phone, but...

Phone owned for less than a month

Bought the phone because it had nice big text in the phone book, etc. Love the icons on the front screen. But then reality hit when my kids sent me my first text message. The font is incredibly small. Went back to the AT&T store where I found out that AT&T specked out all of their smart phones this way. They actually took away a standard feature of being able to blow up the text so you can read it. I called LG and they confirmed that this was done at AT&T's request and that they can't send out the fix until AT&T requests it. My wife contacted AT&T about it and they told her that they can't accomodate everyone and to return the phone as "buyer's remorse". My only remorse is that I'm stuck with AT&T on a family plan and can't go to another carrier who is more responsive to customer needs.
