Re: Xiaomi are banking on issuing frequent, monthly or fortnightly updates"
An unresolved bug with the FM radio, not sure when it occurred as I have never actually used it, and an update in January broke the MiPC suite for a couple of months for some MIUI phones; although it seems the issue was more with the MiPC suite as instead of bug fixing the phone OS, they brought out an update for the MiPC suite.
I have been running the BETA update program since buying the phone over a year ago, and those are the only two bugs I have spotted.
No lock-ups and the only other issue is Googles fault - removing the GPS sensor On/Off switch ; sometimes my satnav software fails to turn it on (but doesnt warn me), and there is no easy way to force it to activate any longer - but that is true of all current Android phones. (My phone switches off sensors it isnt using to save power - I get an average 4 days out of a battery charge, sometimes 6 days.
