Re: Here is a phone I want to buy
My LG G5SE has your choices 1, 2 & 3. I don't know what a notch is (at least I'm honest). It doesn't have 5 or 6 but you can disable the pre-installed crap (e.g. Facebook) and it has a physical power button on the back that doubles as a fingerprint sensor. Of the 3 Samsungs and one LG i've owned, only LG has ever updated the originally supplied OS. I haven't upgraded my phone because the airtime provider don't offer any LGs currently & I don't want to change networks.
