Backup problem Z5

[Cs1575]

Hi

I got my sony xperia z5 a couple of weeks ago and encounter backup problem today. It was running as usual a week ago.

I went into Setting => Backup & reset => More => Manual backup 

then try to change the "where to store file" to my gmail account but it wont sign in.  It kept on saying "online account not signed in".  Not matter what it wont let me change to online account, although the backup account section has my gmail signed in.

My gmail account is signed in in the accounts section as well and I cant find any other area that I need to sign in.

Could someone please help.   This is the first time it happen since I got my z5..

Thanks thanks...

After five days I've solved this problem. things that I had done at this time can be seen below

• reflash ftf
• perform a factory reset
• Make Google Drive trash emptying and if you reconnect than it does.

I heard from  Sony helpdesk to send my phone to the Sony repair center, what nonsense.

For me it works only if I disable the apps backup.

And it doesn't matter how long I wait, it will stick to 50% on all items.

Even so it doesn't matter whether I keep my phone alive or not.

Phone has also been on power adapter and both WiFi and 4G.

This is still an issue. I've got an Z5 and no matter wath i do, the backup failes at 50 % on the apps. I've tried restoring the Xperia Companion for lokal backup, issue is still there. I've updated my Google drive to 100 GB, the phone fails at 50 % with message storage is full (only used 2 GB of 100 GB, so no, my storage is not full!)
Have just opdated my phone to the latest system version 32.3.A.2.33.
Any ideas to fix this will be appreciated:-)
