I don’t follow the market as whole that much – if repairability plays any role for the fans you mention, this is always a big plus for Fairphone. The screen (“spider app”) is probably the most immediately relevant part to bring up in that context. So I don’t see why you could not bring up that point with regard to Samsung, Vivo and Oppo as well.
Good idea, I will emphasize the repairability again.
Repairability is crucial because people can’t go a day without using their phones.
Taiwanese people are unfamiliar with this product; they perceive it as too idealistic and impractical.
In response, I mentioned that the European Union supports FairPhone, and it already exists in the world.
You might want to check first (if you don’t know yet) how Fairphone spare parts provision is dealt with in your country. From far away here, I simply do not know if Taiwan Fairphone users can directly buy spare parts domestically from the Taiwanese company (companies?) that sell Fairphones over there or if they only have spare parts for warranty cases. Fairphone’s online shop does not provide for customer accounts in non-European countries, so there needs to be a different way in Taiwan. If you cannot figure it out, you might want to find out through Fairphone Support.
P.S.: If you find out, let us know. I am sure I’m not the only who’s curious about this.
