I would like to ask the U960 owners, what are the drawbacks of the device?
As any other phone the U960 is not perfect and has some things that could be better.
On the HW side there is not much to say.
The screen is made of glass, is sensitive and well contrasted, but could be a bit brighter for better readability in the direct sunlight.
The screen lacks also any high tech antifigerptint treatment/coating.
The camera is not crap as in most dual sim, but don't expect a Nikon.
The rest is on par if not better than a middle class single sim smartphone.
Very good sensitivity, good battery life, good audio, good CPU performances.
Speaking about SW:
The original ROMs weren't rock solid, and the original baseband SW for SIM1 had some incompatibility with certain SIMs.
All this is SOLVED thanks to our efforts.
There are still some minor glitches:
The received calls and SMS may be displayed with or w/o the international prefix
The USSD replies aren't working on SIM 1
The incoming SMS lacking a caller number are simply ignored by the default SMS client, an alternate SMS client fix this (fully on sim 2 and partially on sim 1)
The dual SIM management, like on the XT532, is relatively basic and is handled better on cheap clones.
Really not much for a single representative of his class, which is still in his infancy.
