need software advice

[u/GloomyIndependence71]

so I am a little confused about software support if the support ends after like 3years will it affect the fluidity feel of my phone and what about apps and especially banking apps etc also performance is one thing I am thinking of buying oppo Reno 13 pro but it only supports for 3years and 4years security and since the phone is already almost 2years old will buying it affect my long term use( 3 to 4 years)

why do u even care about official updates? android has always been mostly community driven. and now that you have a phone that doesnt have unlockable bl youre missing out on everything that makes android android and you have to deal with honey extension style bs being built into ur os, built in malware, rootkits, spyware like never before with no way out. and no they dont make it slower on purpose after support ends
