I live in border area and I always need to set network to manual. Sim 1 is on auto and when I click slider to bring it to manual, I get normal pop-up saying it will disconnect data service etc, but when I click OK it just return me to "Network & internet" menu. SIM 2 is working without problems for network search.
Also, "Preferred SIM for" is gone bonkers - once some network disengage option "Calls" will go from "Ask every time" to other network without my knowledge. Mobile data switching between two sims also causes lot of misbehaving from phone (displays X on network signal from which I switched, etc).
Anyone have same problem ?
