I've M20. I bought it a month ago. I have no complaints. Great battery life,smooth gaming(COD, PUBG,..), slick design. However, A20 is also good, it has better screen (Amoled) than M20, however the A20 doesn't have light sensor i.e you don't have auto brightness. You have to adjust it yourself everytime. If you don't mind adjusting the brightness everytime you go out for a walk, go for A20. Otherwise, go with M20. P.s Xiaomi Redmi Note 7 is the same with M20 but cheaper, it hard to find it in Ethiopia though. Xiaomi has the best UI, it looks just like what iPhone would be like, if Steve Jobs were alive
