Mr. Ajmera's Review (A business user)

My smartphone, no doubt, has to efficiently performs professional functions such as Document Viewer, Pushmail (Exchange ActiveSync), which Sony Xperia U does well. A small device like this might neatly fit in my pockets, but that's all it can and nothing much with the cramped screen size of 3.5 inches. I more than often go for efficient devices like the as it present me with a robust call management; as I am hardly ever off my phone. Bluetooth in my smartphone is essential more for hands-free calling than file sharing. I am mostly traveling around and even if it is in known streets, I prefer having my GPS navigation guiding me along, in case of traffic or diversions.

Mrs. Iyer's Review (A homemaker)

I hate typing messages on the Sony Xperia U with its tiny keypad as I misspell a single word more than 3 times. Video recording is fun and lets me record all beautiful memories of birthday parties and the energy and excitement of a house party. A smartphone without a good camera is really not my choice, even if the Sony Xperia U sports other excellent features and fairly makes up. If you have as many photographs and videos on your phone as me, then you might have to delete a few because within few weeks you will face storage issues.

Ishan's Review (A geek)

The 3.5 inch display may be quite decent for a smartphone but I don't like it for my reading or gaming purpose. Gaming is really a turn off on this 1 GHz smartphone; reading is still bearable. Dealing with lags and slow load time really makes me impatient when it comes to gaming. An internal RAM this low isn't capable of handling any level of multitasking or gaming. A hardcore gamer true to his passion would never prefer a smartphone with such a low storage, even if it can accommodate most of the apps, music and ebooks.

Prachi's Review (A social butterfly)

The 3.5 inches display of the Sony Xperia U was the first thing that grabbed my attention. I prefer texting over talking but this screen size is way too cramped to do that easily. It's not that amazing to own a smartphone with Yes, 5 MP camera resolution. There are cheaper options available that too with better camera resolution. I click hundreds of cool pics with my smartphone and don't think the pictures will be so cool with this phone. For me, a smartphone with secondary camera means loads of selfies. Me and my friends are a huge followers of the selfie and groupie trend, we hardly stop clicking 'em. If you find clicking selfies as cool as I do then you should definitely opt for a smartphone with an amazing secondary camera. My smartphone should be doing more than messaging, browsing and emails and that too simultaneously. I feel 2G networks are not reliable when it comes to this. I like the GPS feature, especially for new locations and traffic updates. I don't worry charging when I can charge my phone with the laptop; I can even transfer files with this. I can't be choosing between which media files to keep and which ones to delete, due to internal storage as low as 8 GB. It's irritating to delete favourite files from my smartphone due to memory issues, so I always go with larger internal storage.
