If my current iPhone malfunctions continuously, will that malfunction pass on to brand new one?

I had an IPhone 6 (or 7) Plus & it seemed to have a mind of its own. I would write a text, and a different text would appear. I would get texts & voicemails late (over 2 hours late), Facebook often stopped after 10 posts. Upon examination, Apple said it was fine. Then When I purchased my new IPhone 11 plus, I had my old information transferred… & was told it could not be affected by an older malfunctioning iPhone. Whether you call it a virus or something else, neither phone worked correctly. I am therefore reticent to transfer anything onto the new phone I hope to buy. Any advice… besides reassuring me that IPhones don’t get diseased? Thanks for any advice you can pass on.
