Pro: Light weight ,very nice picture on a bigger then adverage screen ! Con: Claims it comes with games installed ,no games on my phone ,cant thing of anything else I do not like about this phone ! Using experience: 2 months I actually purchsed this phone for my young son ,I liked it very much plus its bluetooth enabled . My phone a Samsung A850 did not have Bluetooth ,however its a flip phone with all of the other features on the R400 .Well one day my son asked if I would trade him phones I jumped on it and Iam glad I did ,it has a larger screen then the A850 ,bluetooth ,which in Ca. will be very much a needed feature ,a new law is making it illegal to hold a cell phone while driving ,going into effect July of 2008 ! I really like just about everything about this phone the R400 ,we have 4 cell phones in my home and all of them are Samsung ! Less
