Done the latest software updates and my phone is in a terrible starte!!
What I've done
It's that bad I've got my old iPhone out and using that!!!
HELPPPPPPP before the hammer wins
Since upgrading to build 23.4.A.0.546 my phone has had a few serious issues that it has never had before. It could be related to my screen because I had to have a replacement fitted a few days before the update came out, but I can't be sure which is causing the problems.
I mostly notice it in messaging apps (the default Messaging app, Facebook Messenger, InstaMessage and WhatsApp) but it happens in the Music app and Google Play as well.
It looks like the app keeps refreshing itself, there is a very fast wiping and redrawing of the screen. If I'm in a messaging app it is very noticable because it causes the keyboard to disappear (I've tried a few different keyboards and the result is the same).
*edit* It is far more pronounced in WhatsApp, which over the last 2 days has started acting like I am pressing the screen all over, opening menus, calling people, trying to take photos etc, all without me touching the screen at all! *edit*
In the Music app and Google Play it makes opening the side bar menu almost impossible, because even before the side bar has slid out, the screen refreshes and it disappears.
Can someone who knows tell me if all this refreshing could possibly be a screen related hardware issue, or is it software/firmware based? A colleague with a Z3 compact said he had noticed similar issues since the latest firmware update.
Any help would be appreciated 
I'm afraid that this sounds like a hardware issue to me.
I recommend that you contact a servicelocation or your local support team for assistance.
My phone no longer recognises the USB for file transfer. It does not show up as connected on the phone or the PC however is still charges but i seem to be getting a lot of the problems listed, battery life seems reduced, phone gets hot and my apps randomly shut down. The phone is only a month and a bit old and was fine until a couple of weeks ago. Any help on the USB issue will be much aprrecitated as this is a replacement phone for another xperia z2 which camera stopped working the day after purchase.....
Anyone have any ideas?
Bugs I encountered so far:
I really regret having to update my Z2 with 23.4.A.0.546. It is just a shame why would Sony push this update with these bugs like it did not undergo strict testings. Tried already factory reset but it did not fixed the issues.
UPDATE------
Thought I would update on how I'm getting on. Been using old Iphone for the last few weeks and Z2 has been sitting in a drawer collecting dust. Was gonna stick it on Ebay and buy another Iphone but desided to do one more PC fix again (5 or 6th time since problems started) and it seams a lot more stable!!
SO FAR SO GOOD!!!!
Hi All,
Read a few post on here with regards to the annoying notification tone when signal is lost and regained, but has anyone found a solution to this?
It's driving me mad as I live in a low network coverage area and it's like every 5 minutes, I'm sure the misses thinks I'm having an affair!!! Below are a list of things I've tried and have not worked
Thanks
Hi Bearings,
Thanks for taking the time to advise.
I have already run it in safe mode and erased all the apps that are not factory set.
Still the same problems.
Thanks anyway and I'm sure this might be useful to others.
Thanks

Glad to hear that your phone works better now.
Regarding the SD card issue. Could you download this app and have it installed for a week or so and see if the SD card is mounted/unmounted: https://play.google.com/store/apps/details?id=com.sdcardmonitor
If you could test your SD card with a PC and a card reader with a test software like h2testw as well to make sure it's not an issue wioth the card.
