Hello there

i have the same problem that you have, 4G got very bad when both sim work in mobile when one removed every thing is good what ever the slot you are using , i have talked to all support agent chats  live support no one gave me any answer i tried factory reset and install new ROM and the problem still the same,

after Dec 19 security update installed i can't roll back to older version to fix this no available solution works till now , this month we've got security update i don't know why and what issues has been fixed no one care about this, so soon i will leave this mobile company to another one care about it's customers  how much time we have to submit reports about issue to solve it  customer satisfaction is not important for you very bad support and very slow solution
