Xiomi have been known to produce really cheap phones which contain the latest technology anx tge current features which can be seen in flagship phones.Mi A1 is a good looking phone and with the new and very loves portrait mode was going to be the go to phone for many people but it was not to be.A1 has been having heat problems from the beginning because of its aluminium body and glass panelling heats up to an uncomfortable temperature and this problem occurs whenever you charge the phone or overwork it.It is not properly optimised for android oreo and often lags when you open more tabs.If you are looking for a good performing phone then this is not suitable for you.
