Recommended ROM?

[DevaVictrix]

I only use my smartphone for OTPs... Authy, the Steam app etc and hopefully my bank account app. The thing is, the bank account app only works on Android 6+.

Given all that I want is Android 6 or above please can someone recommend a ROM. Something that works well...GPS and WiFi included. The phone doesn't have a SIM card and I'm thinking about using it to track my running.

Thanks for any help. I've barely used a smartphone since the s4 mini came out so I'm a bit overwhelmed by it all!

I don't use banking apps and GPS only rarely. Last time battery drain because of using GPS. Well, maybe because of Sunlight...

LineageOS 17 works well. Use the right version. Banking app with Magisk Root should be possible, but I don't know how.

A new cheap phone with original ROM and better GPS may be better for you.

Thank you for your reply. I'm sorry it's taken so long to respond... accidentally wiped my password manager file, lost my login details and forgot which email I registered with! Nightmare!

I'll give LineageOS 17 a whirl.

I'm sorry to ask a question that has been asked a million times!
Is there a straight forward set of instructions available to help me flash my phone? I would like to make a backup of the current (factory) ROM and then flash it with a LineageOS 17 ROM that hasn't been tampered with. No offence intended to people that mod released ROMs, I'd like something that has come from the initial developers.

Thank you!

EDIT: Yes, I have considered buying a new phone. I love the size of the Galaxy S4 mini and have seen that Sony (I think!) has released more recent phones of similar size. I may well buy a replacement if I can't get LineageOS to do what I need. Thanks

I should add that I prefer to use Linux (OpenSuse)... if Windows is necessary it's WIndows 10.
