OthersBoth handsets have connectivity features like WiFi with hotspot functionality, Bluetooth, 3.5 mm jack, GPS with A-GPS, and micro USB port. However, Samsung Galaxy Ace has an additional DLNA (Digital Living Network Alliance) feature, which enables sharing of digital media between multimedia devices.
The Canvas II is a dual SIM feature, and that certainly gives it some advantage over Galaxy Ace, which only has a single SIM slot. It also has 2 GB internal memory and a storage slot for up to 32, against Galaxy Ace's 158 MB internal and 32 GB expandable memory.
ConclusionIf you are brand conscious, then this comparison is useless for you. However, if you want a big screen with decent features, then we would suggest that you go for the Canvas II.
We have been using it for quite some time and are happy with its performance and looks. If you are considering the Galaxy Ace, we would recommend that you see the users' comments in our earlier stories.
