iPhone SE is the king of small smartphones. I’m sorry, people. You can still get new ones from some carriers and there are a million people in the used market. Running the latest operating system, clean, without bloatware, runs, respectively, since I’m just an iPhone 6s reduced to a 4 "phone. Slower than an XR, but certainly usable, you do not feel compromised, And don’t forget that it has a headphone jack! I repeat once again, I really like this model so I suggest you buy it! All the best to everyone! Buy iPhone SE: D There is also the Samsung A40, it is good but I understand that there are problems with the battery.
