Allegro is a window phone produced by the acer, it is notgood phone, it has notgood shape and design I like it, it is 2g and 3 g phone, this is light weight phone, but it has small screen size it has only 3.6 inch with 16M colors really screen is notgood quality, it has window 7.5 Mango operating system.
And in this phone 1 ghz processor, no memory card slot in this phone it has its own internal memory 8gb for the user, it has 5MP rear camra with autofocus and geo tagging.
But don’t have secondary camera, its sound quality is notgood, which plays music very well, it connectivity like bluetooh wlan are average notgood, nits battery backup is upto 7-8 hours while using, the main drawback in this phone that is it don’t has camera FLASH, I used this phone only 4-5 month I have little bit bad experience with this. In this phone no hanging problem occur. I recommended to acer please improve this phone.
