Xperia U generally received a positive response from critics with some calling it as a budget version of Xperia P and Xperia S. Critics praised the Xperia U for several features like a dual core processor, high quality Display, and its 5-megapixel camera but criticized it for the lack of external storage and no Android 4.0 Ice Cream Sandwich out of box which is available only as an upgrade. Natasha Lomas of CNET gave the phone 4 out of 5 and wrote "For Android lovers looking for a budget smartphone for dainty snacking on apps and mobile websites, the Xperia U is a worthy contender. It fits the budget and is cheerful, cute as a button and – provided you're not too demanding of it – fleet of foot."
The Sony Xperia U comes with 8 GB of phone memory, 4 GB of accessible internal storage and from the remaining 4 GB, 2 GB is kept for system memory and 2 GB is kept for applications.
