[General Topics] adamchap:
Question on my next device. I've got a Galaxy S5 at the moment, rooted and running Lineage 14.1, Magisk and a ton of good apps. I'm conscious that it's getting a bit physically old and battered and I'd like to move to a newer device.

I've considered things like the Ulefone Gemini Pro 2 and the T1 as they're great looking and good performing devices but have concerns around them (ability to root, no Lineage option, etc). So I'd like to ask my xda colleagues their advice.

I'd like the following minimum specs/things on my next phone:

Screen size - not fussed but not phablet. S5/S7/S8 screen size is MORE than enough for me

Funky features - I really don't care for 'squeeze the sides', 'edge devices' or full screens with notches in them (Essential Phone)

Battery - big as it can be. If it's removable then fantastic as I currently carry a spare battery in my wallet, far more convenient than a battery pack.

Memory - minimum storage of 64GB, 128 if possible. If 64GB and I can add an SD Card so much the better but I'm alright with no SD I guess

USB - don't care on whether it's type C or not

Charging - fast charging is nice, really don't care for wireless charging (too inconvenient, too slow)

Processor etc - anything has to be faster than my Galaxy S5, so something 'decent' - I'm not a massive mobile gamer, so good solid 'no lag' performance able to be a bit nippy when it needs to be

Sound - I don't need a special audio stack, 3.5mm jack would be ideal but ok for USB C headphones too, not a deal breaker due to adaptors

Camera - I'm happy with my S5 camera, so anything these days has to be an improvement, right? I'm a happy snapper, not a specialist photographer or amateur enthusiast, so a decent back camera and flash works for me. I don't video chat or take selifes, so the front camera is largely irrelevant to me, but again it'll be better than I already have I guess.

Build - plastic or metal, I don't care. My S5 is plastic and the back is replaced with the built-in leather flip case.

Other stuff - NFC (need for Androidpay etc), Bluetooth (essential for speakers and the car), fast wifi capabilities, single SIM card fine though dual would certainly be attractive for BYOD at work.

Must haves:

Must be able to easily get root

Lineage OS either available - or a real possibility (i.e. that's why I won't go Ulefone, it just won't happen realistically).

If no Lineage just now, updates from the vendor are forthcoming (I don't want to be stuck on 7.1 forever)

Some decent accessories available - nice covers and able to get stick on glass screen protectors for instance, another reason not to go unknown

Open to odd Chinese etc brands based on the above. Must be able to buy SIM free and use at home in the UK on the 3 network (so GSM, GPRS, 3G, LTE - plus GPS (other stuff like GLONASS a bonus) - and travel round the world extensively - US, Asia, Europe, Africa - so multi-band essential). Warranty/support in case of problems a consideration but not a show stopper (if I can buy from a UK or Euro retailer such as Handtec and it's DOA or a problem I'll just go back there).

Can any of my xda friends and advisors suggest something as I'm struggling to figure the market out at the moment. I'm a pretty experienced smart phone user, from Palm to WM6 to Android since Gingerbread but the market is just so weird and fragmented at the moment. (Vendors if you're reading take note: if it's hard for me....)

Thanks in advance, sorry for HUGE post but this will determine my phone investment for the next 3-4 years.
