Hello engineers of Sony. I recently upgraded my Sony ZR to lollipop. Big mistake!!!! It is extremely heavy and slows my phone down. Downgrading it back to kitkat is pretty tricky for a non-IT person like myself. So please either provide us with an upgrade that would enhance the performance or give us some app that would allow us to go back to kitkat. And please do it quickly. LIKE YESTERDAY! Thank You.
