The trouble with Android is that aftr a while it ends up with brain rot.
My 2012 Nexus 7's physical hardware is fine, but I found it was getting slower and slower and some features weren't working, software was failing to operate correctly.
So I wiped the tablet and started over, and it's now snappy and responsive and glides along fine.
I found Nook e-book reader, Barnes & Noble's display and store interface, had a process running in the background of the tablet constantly. Its by no means the only app that thinks it needs to subvert your OS for poor reasons.
This leads to a situation where you either carry the minimum software on your tablet, or you install the software for the services you use and kiss goodbye to stability and response.
This would be poor if it was merely an Android problem, but it's also a problem on other operating systems.
My desktop PC is virtually unusuable for the first five minutes after booting. The log in prompt pops up in a few seconds, but then... Oh dear. THere's at least three apps which insist that they need to do a hard drive scan and a haost of otehr apps that wantt ot load up and stay resident, and all of them either want to upload a lot of data to cloud services, or fight each other over who gets to check for software updates.
And unfortunately it's all software I feel strongly that I want or need.
I think the next wave of OS features will have to address this.
