Android okay but it inefficient code hence why need so much RAM & so many cpu cores . I install computer controlled manufacturing plant equipment that needs less ram than a android phone, it fooking ridiculous lol .
Android bit easier achieve many task but still many issue without rooting, Language font support being one, why the fuck Google do not have 100% support for all languages or an easy font linking folder for adding secondary font for unsupported languages is beyond me, they simply are not trying.
burmese language being a big problem but fortunately xiaomi devices is easier fix via a burmese zawgyi font added in a theme file rather than rooting and adding modded system fonts.
Advertising in apps is also a big piss off for me I fooking hate it :-)
Amount of google bloat sucks too .
Not that any other phone OS is much better these days, they simply not trying very hard.
Windows done some impressive stuff between 2003 & 2006, Iphone ios and android had not even been born but if you look at wm2003se & later wm6 you will see how similar android notification bar etc is and also see winmobile had bounce effect in menus when swiped to end so not an apple miracle idea at all.
also wm2003se had obd software and could connect to our R nissan obd1 for fault data & onscreen sensor dials etc and that was 13 years ago ...
Basically operating systems are not evolving much & becoming way less user flexible and way less hardware efficient .
Moaning post finished , lol ...
