I’ll consider a Linux phone as long as the following are met:

• Battery life is decent (for me this means a minimum of 24 hours of light use and no mystery drains).
• Reliable enough to not fear for my life when traveling.
• UX is polished enough to not be painful.
• Email notifications and communication apps work correctly (Signal, Telegram, WhatsApp).

If these are met, I’ll buy whatever is available in a year or two.
