Samsung D800 and D820 (SGH-D800 and SGH-D820)
“The Samsung D800 and D820 are two sliding phones very much in the style of the previous D500 and D600 handsets. What’s baffling about these two phones though is that they actually not as advanced as the D600, and yet their model numbers would indicate that they should be better.
The D800 and D820 are very slim phones, but they’re not particularly lightweight. At 14.9mm thick they are substantially slimmer than the D600 and other sliding handsets. But they’re not particularly pretty phones, and for some reason Samsung have chosen to cripple the D800 and D820 needlessly when compared with the D600 phone by including less features.”
