I don't know what is wrong with this device. Periodically I can see the red icon telling me I don't have GSM signal. All of the mobile functions are lost (3G/4G, voice and messages). After a few seconds everything is ok again.
I have the lastest version of official software and even without any third part applications the problem occurs.
Anyone has the same problem, or know some solution/workaround?
Thank's in advance.
