Usually people speak of this as an advantage but I also think it is a disadvantage, one of the reasons for wider usage of iPhones ……

• there are crappy android phones
• historically android was crappy (even if it is much better now)
• most android phones are loaded with bloatware.
• most android phones are poorly supported or for only a short period
• privacy and security can be a challenge for regular users
• inconsistent usability

Meanwhile, iPhones

• are always “good”, even the lower end
• historically held leads in usability, features, even if not true anymore
• no bloatware from vendors
• full support for 6 years
• claim privacy and security by default
• good usability
