Tab from mi is waste of time and money, charging takes longer duration to full charge say 5to6 hours. Spares are not available in service centres, recently my tab got stopped working after full discharge, and it neither switch on nor takes charging. Mi Service centre people says lack of spares.
After 2 and half years, the perfect piece ceases its working upon a minor water entry through its headphone jack. The device doesn't boot up anymore and stays in the crystal-clear start screen displaying FASTBOOT. I can say that the tab was amazing in specs and it entered the market prior to the timeline. Beware of water entry, all users, otherwise its an invincible make. Farewell dear MIPAD.!
