How to uninstall last software update??

Question

Since your upgrade to the newest software, I have a lot of problems. It's more "missing options" than problems. The silence option disabling data, no option to open contacts during a calk, only if going to menu and contacts, and in contacts additional window appears, so if I need Favorites, I need to go over the general window. The only 1 good thing in this update it's the camera. All the rest did awful experience of using sony.

Answer 1

I support this.
Much people have A LOT troubles with Lollipop. Not only bugs-n-lags but interface itself is user unfriendly.
And most of this peoples isn't experienced enough to do mentoned "geek procedures", and/or have no time for study them.
So they just blaming SONY and bying new phone. Throwing away or trying to sell their old Xperia Z*/compacts.
In fact, there is MUCH Xperias on local second-hand goods markets after the last update. If in January most ads was "bying SONY", now it's "selling my xperia". Some trying to sell 3-month old devices for the less than half of the price.
I find it's totally abnormal.
