It basically killed my first android phone, which was very low end but fine for my needs when I got it. But it came with a ton of non-removable apps which were fine at first, but then they slowly grew to take up more and more of the storage as they updated, til nothing left. I could downgrade them again, I think, but they would soon update again and use up the storage. I guess I could have disabled update, but I wanted that for other things. Ended up jailbreaking my phone so I could remove them. But then other apps like the one for online banking refuse to run because "security reasons"
