Weaker phone signal after Lollipop update

[Sam181]

Hi,
I recently upgraded to lollipop, and now have problems, the phone signal is weaker and cuts out during calls and it runs the battery flat quicker. Dies anyone know a solution?
Thanks

Since this is a major update, you should reinstall the latest update with XC

Xperia Companion (XC)

Hi thanks for the reply, I have 2 M2 phoned, I did install one with XC the other was not. Both have glitches since update. Such as the calendar crashing and the clock vanishing, but the worst is the phone signal and energy use.
