The truth is the upgrading of my smartphone is not something that I have total control over because every now and then they send me notification for update. And even if I refuse to update it at the first time it's sent by discading it, they will continue to send it until I will finally decide to upgrade it.
There is something I've come to observe with my phone after upgrading it, the device becomes completely different from how it was. And this changes to me most times seem to be cool while other times it's just like waste of mega bite used in upgrading it. For instances, previously, my gadget wasn't having scientific function on the calculator. To my surprise, after upgrading it, I noticed this function was on the calculator(positive side of the upgrade).
But what I dislike a lot about the upgrade is the installing of apps that I don't want. The only thing they do to my phone is take up storage up, draining my battery and popping up annoying notifications I don't have need for.
