I just got a 2nd Samsung Galaxy S2 today in the mail... I noticed right off the BAT 2 things are wrong..

1) the screen has a yellow tent to the whites.. the other (first one) is PERFECT.. they are both set exactly the same in brightness and I have changed them both and they are still the same issue no matter where I put the brightness..

2) on the one I got today (also the one that has a yellow tent) if I go into mail I cant add the yahoo account to it.. If I go into mail in the first one it works great when i configure it for yahoo..

I sent into settings and found this..

Please guys help out.. should I send this phone back or can I match them some how.. I connect it to Kies and it says it is the updated version it says it on both of the phones.. HEKLP PLEASE

 

Yes from the USA and like I said the first one I got works GREAT everything and is Bright and the yahoo mail (can be configured) using the Mail account (and using the Add Account option)

The second phone isnt as bright (has a yellowish tent) and also always says "bad username or password" no matter how many times I try and configure it..

The photos show the new one (on the left) is less bright no matter where I set it and also the one on the right is the older one that works with yahoo and also is brighter

 

There is no US Warranty (I got mine on Amazon) but you can get it if you go through the country that it came from.. Pain but I hope I dont need to use it.. If you want all that I would wait till it comes out in a few weeks.. But I love the (home button) and the US version wont have that..

 

The US verson wont have the main home button on the buttom (like the iphone) but the Internation version does..

Also if you buy it from Amazon you have 30 days to send it back to them (they will pay for shipping and all that back to them)

I got mine from some vendor that sales through amazon
