I am samsung a50 user and this phone is worst. Many people didn't notice but the performances of this phone is going down as time passes, there are many bugs and glitch if you're onto high usage applications. shifting of network band is major problem of this phone, Data connection and network is not constant because of shifting network. I am not heavy user but still i don't like these kinds of problem in any phone. they are making lots of phone like a50 a51 a52 a53 a54 a20 a21 a22 and so on and they don't know how to make better software experience for user because of large production. They made some minor modification and throught it on air when they released the android 10 ..haha without testing it on other A50 phone. Plus battery estimated life is not close to approximation, sometimes downloading is slowing down when phone is locked even when you are downloading from playstore, solution are there by disabling optimization but this is not great understanding of OS that what is user want to do with it. I hope samsung will resolve all this by android 10.
