You're not wrong there, with the constant development of smartphone software and the like there are so many new changes every time you come to upgrading your phone. It's similar for me despite growing up and having tech as a hobby, yet I'm only 29 haha.
Saying that though, Huawei / Honor's EMUI can take a lot to adjust to and this is coming from someone who has been using Android for years, it is one of the more complex customized OS's out there - so many options / tweak adjustments available that are only found in menus within menus. To be honest I still prefer OnePlus's OxygenOS as it's much more refined in my opinion, but over time you will find your way round EMUI just like I did and it isn't as complex as what it once was a couple of years ago.
Strangely enough I used to be with EE up until a couple of years ago but then moved over to Giffgaff as I experienced terrible signal issues with a new build that we moved into and also signal dropouts when at work. It used to drive me mad at home and at the time I simply put it down to the new area we were living in, but the Mrs who is on O2 never had signal issues. As soon as I moved over to Giffgaff - problem solved at home and at work.
That also reminds me - managed to sell on my old OP5T over the weekend, aaaaaand DHL have only gone and misplaced the parcel. They've already conducted a thorough search their end and have concluded that it's no where to be seen & have started proceedings to reimburse me... frustrating times indeed.
