Problem solved!
it is a magnetic problem: there are some magnets at gps/antenna/wifi panel on bottom of mobile (under home button) put it for tasks with flip cover (like sensors)... magnets are more powerfull than reductor put it on it at several times... and take effects over antenna, specially when E band comes active and it will be interfered, magnetics of flip cover takes effect and screen being locked.

Sollution: made a "Faraday Cage Effect" over this reductor with a copper film (adhesive it is better because if isn't it adhesive you have to weld this film)
at several times, flip cover loss thier effect (if you have it)...
