This is what I would do
1. Get a brand new MICRO SIM card, make sure that it is a MICRO SIM card and not a trimmed SIM card.
Double check the APN settings, make sure that you have the correct APN settings
Check with your network for any LTE coverage issues
Which version of the Z Ultra do you have? which carrier and country?
2. This is more of a preference, it'll be good to have the option to keep the screen off even while answering a call.
3. That's an Android issue not Sony, you should contact Android devs or check the Android forum.
4. It'll be wise to
a. reformat the SD card
b. reinstall lollipop with PCC, it will smooth things out.

Well, first update to my situation. My SD Card is genuine SanDisc. I checked it on the PC — there is no mistakes/bad sectors at all. And File Commander gets I/O errors every time. Since I have not rooted device I can't use any other software to write to SD.
upd: card is exFAT. it was no problem in KitKat, but maybe it is in lollipop?

total commander can write on sd in not-rooted devices.
how exactly did you check your sdcard?

After the recent update, my phone's battery drains very fast. I used to love the battery feature in my ultra but now it reduces very very fast except that it also charges very slow.
And after update, I'm unable to reduce the home screen grid size on my Z ultra as it can be done in the previous version.

IVE GOT A SEVERE PROBLEM IN MY Z ULTRA,
Just updated it to lollipop from perfect kitkat, battery was 97%, after update it was 61%.
Kept using it and enjoying the new UI until it reached 15% and battery notification popped out. Kept it in dock charger which i have been using with no problems for almost a year now (because my micro usb doesnt work).
Came after 30 minutes, it was 2% and a message saying it's draining faster than charging. Tried my mate's Xperia Z Ultra which was still Jelly Bean it charged perfectly, so hardware isnt a problem here.
MY PROBLEM IS:
IT NEVER GOES OVER 3% battery percentage even after 5 hours of charge while off, and drains in 10 minutes of being on even with charger plugged in!!!!!!!!!!! Sony promised that this update will be worth it, I don't think it is!
Please find me a solution because deleting and restoring isnt going to help me, as I'm a student and got very important documents and pdfs in it!!!
I really thought I can depend on Sony, dont let me down now!

you should be keeping backups and not relying on any single piece of equipment for important data.
Use sd card, google drive, dropbox and offline storage in multiple locations
