As far as makeup goes, a little foundation goes a long way, find a tonr that works for you (plenty of guides out there for picking the color) i use a full-coverage, it makes blemishes and facial hair shadows blend in. A concealer can also help if you have particularly high contrasting "blemishes". Searching you favorite video hosting platforms will yield many make-up guides and tutorials. Find a streamer/creator who has similar hair color/complexion as you and wing it. Worst case scenario you grab the makeup remover wipes and try again.
Yeah, i just run a very heavily modified android now. Hard to find good phones (with features that i want and need) with enough software support. Couldn't get lineage os working on my zenfone, it was a horribly buggy experience and I couldn't get mobile networks working. I needed more reliability and stability, so i manually debloated and stripped almost all telemetry. Rooted this thing and blocked anything that isn't whitelisted.
Not OP, but when i was running custom ROMs on my main device I carried 2 devices, i had my main phone in my pocket and my secondary in my purse. The secondary ran "Android" so i could use tap pay and the like.
Any time my players try to do stuff like that i have them roll initiative and start a turn order, the "victim" NPC rolls with advantage b/c shop keepers are gonna be explicitly keeping an eye on stuff (unless they are distracted). There's a lot of nuance to it too so each encounter. I do hate making character sheets for every NPC though.
I personally am all for flair, but it must be optional, i have so many silly bits of flair on my phone that l chose to be there, it makes it mine. I refuse to use an apple product (unless absolutely necessary) due to the lack of being able to personalize it.
Speedy thing goes in; speedy thing comes out.
