Recently I've been looking for a phone that will allow me to install an google-free OS. I've never installed a different OS on a phone before. I've been looking online but haven't really found a clearly best option.

Problem with standard recommendation

From what I've read GrapheneOS seems the best alternative OS. Unfortunately they only support the Pixel devices. I want to have local, offline access to my files (e.g. music files, documents) and don't want to be dependent on cloud services. The Pixel with the most storage comes with only 256GB and no slot for an SD card.

Possible options

There are some other routes that may be feasible that I've listed here.

Fairphone 6

• No USB 3
• Pricey for what you get, both in terms of hardware and in terms of fairness, at least according to this post).
• It has an SD card slot
• You can order it with e/os installed, very convenient
• No GrapheneOS

Fairphone 5

• According to this post, the FP6 is a lot snappier
• Not significantly cheaper than the FP6
• It does come with USB 3
• It has an SD card slot
• Can also order this with e/os.
• No GrapheneOS

Sony

According to the Bootloader Unlock Wall of Shame Sony isn't the worst of the bunch.

• Many Sony's from the LineageOS list of compatible devices have an SD card slot
• Have to install the OS yourself
• No GrapheneOS

Pixel

Get a refurbished Pixel anyways and get a separate dumb MP3 player for music.

• Might be an option but 256GB is still cutting it tight with what I want to have available offline.
• The 256GB option is a lot more expensive than the 128GB option compared to the cost of a 128GB SD card
• Extra costs from buying the extra MP3 player
• Have to install the OS yourself
• Can install GrapheneOS

DumbPhone:

Get a dumbphone for calls, texting, banking, govt stuff, 2FA app, and music listening. Have a separate linux phone for all the other stuff.

• Not sure how privacy friendly the dumbphones are, might still be using Google Play services?
• Two devices instead of one to carry around
• Extra costs for two devices
• Tinkering with a linux phone could be a fun project

Bonus option: don't get the linux phone

• Less screen time
• Only 1 device to buy/carry
• Can't go on the internet while traveling

Questions

• What would be your recommendation that allows plenty of storage on the phone?
• Do you have good/bad experiences with any of these phones/operation systems?
• Are there any good options I've missed?
