Upgrade needed for Nokia 8 as medium class premium phone requirements are expecting more. In the 25k Indian rupees, the requirements are growing. Android upgrades are there to Android 9 Pie. Top notch display is swiping away the premium market segments. Speed is the key component in a premium phone at this price range. So my opinion is to upgrade Nokia 8 like 6.1plus or 5.1plus by staying at the perfect price range.
