Owner of two zenpad 10 Z300, I'm facing consecutive problems on switching on the most recent one (new, with only 2 month). Every time I need to switch it on, I have to presse the button for several seconds. Today I had it on fastboot mode, solved by pressing during 20 seconds. This is not normal nor correct on the device. Guess I have to deliver it.

How can I default Google voice assistant my phone please help me
