What was strange to me occurred in the first moment that the packaging looked as if it had been already been opened (I had ordered a new device).
On the cardboard taped a piece of paper which contained three indecipherable letters.
This struck me though Spanish before, but I did not want to think about it because I finally held my latest treasure now in his hands.
After the first start to Android 4.2.2 JellyBean was on the tablet.
After 4 (!) Updates to 4.3, 4.4, 4.4.2 & 4.4.4, he was calm and I was finally able to marvel at the (really good) display.
After two days I noticed that the tablet at the back was excessively warm.
An app showed me at 53 ° C under normal surfing the preinstalled Chrome browser.
On the Internet I found a possible reason: The processor of the Nexus 10 will default to 2 cores @ 1.7GHz operated. This could be one reason for the heat.
So I have rooted and down clocked the CPU manually.
Used has nothing.
Eben, the back has strongly curved outward and the temperature rose to 61 ° C (2 x 1.1GHz).
I'll return the tablet now and order a new one.
I'll post an update as soon as something is happening.
