Test No. 1 and No. 2 now

Got on Friday my first copy of the Lenovo A1. At first I was pleasantly surprised, good workmanship and no dead pixels (became). Ran to the charger, then in the evening the first Test: Device will not turn on :(, strange behavior, every few Miniten tempted the tablet on its own mute, there appears briefly the Lenovo logo, the speaker pipst, then it goes out again, all very strange. Well, a little surf, trying again and again, then suddenly it went on and ran from then on also without problem. I kinda played around, Softwareaktuallisierung conducted tested SD card, all good. dannn in YouTube app much me, more than Gepipse does not come from the speakers, headphones, everything was ok, manure, unfortunately the built-in speaker does not work, unit defective.
Let's see how fast that goes with Amazon, have never been to reclaim something that'll get when the exchange has arrived, very much hope that then everything works. Unfortunately, so far only 2 star, hope to be able korregieren next week :)
