Hi,
today I had an interesting (?) chat with Amazon. They want me to install the last firmware. I told them I had 5.13.2. After some conversation they mean that they had installed an new one, called
Software-Version 039-juno_1302_cognac_zelda-366142
After restart it is still 5.13.2. They think the Oasis will work well now.
And a wonder: The reading time error is still present. Nice present
