BroadcastReceiver not triggered

view story

http://stackoverflow.com – I'm finishing my application and got to test in various devices. I have tested into Galaxy SIII running 4.0.x and 4.1.x versions, and with some 2.3.3+ devices (I have heavily tested into 2.3.x devices, because on my mind, the bugs was to appear more into OLD devices). My problem comes with Sony Xperia U. When I tested with 2.3.7 ROM, my application worked fine, but when I upgraded these devices (I have access to 2 xperia u devices), my application Broadcast Receiver of SMS isn't being triggered. I have double checked my permissions and I repeat: It works in various others devices. After look (HowTos)
