And the reboot takes a lot of time.&nbsp;</P> Tue, 20 Jun 2017 18:34:15 GMT https://community.sony.com.mk/t5/xa-series/phone-restarts-with-change-in-data-preferences/m-p/3551570#M12438 gr137 2017-06-20T18:34:15Z https://community.sony.com.mk/t5/xa-series/phone-restarts-with-change-in-data-preferences/m-p/3551571#M12439 <P>I tried changing sim cards and the problem is with a particular sim card, ie.
