Android Lollipop - a massive backwardsbackwards performance step

Try clearing your Dalvik cache. Shut it down, restart into Recovery, select the option to clear the Cache, then restart it again.

I thought Lollipop ran on ART and not Dalvik?

Whoops...old habits...

Wipe the cache partition 🙈

I have the Sony Z1 also and have had the exact same experience since the forced upgrade to Lollitulipe a few weeks ago. I was very happy with my phone on Kitkat but now it is horribly slow, unresponsive and buggy. It crashes often, overheats and locks up for no reason. It's a shame we can't choose the android version to stay on.

Is there any way to fix this?

You could flash it and downgrade it back to KitKat bare in mind you'd have to flash it would a KitKat Baseband before installing the ROM, XDA has some really good guides and ROM's on their site.

If wiping the cache partition doesn't work, then before trying to revert to KitKat, do a full system reset and reinstall. I resolved issues on my old Nexus 7 tablet doing this. It was unusable after the update but fine after the reset

I'm exactly the same. A Z1 compact and it's been doing my nut in the last few weeks. Whenever I send a text, it's like I'm having a stroke.

I gave up and just got another phone (only to find it not much better - Note 4)

I'm in the market for a new tablet and rather than waiting for the new Z4 which should be out any day now I am going for the old Z2, mainly because it doesn't have this rubbish LollyCrap.

Blimey I'm still using a Nexus 4, but running lollipop it's fine with none of the problems reporting

I've noticed though that it uses more memory than it used to though, and being Android when you close apps it doesn't really release the memory so you need to do that yourself or use another third party app to do it
