vivo is working on the V70, the successor to the V60 launched back in August. This series refreshes twice a year, with the V50 having arrived in February, so it's unsurprising to see the V70 already getting certified for sale in India by BIS. As is customary, this certification doesn't reveal any specs for the phone, which will have the model number V2538. It does however confirm that the phone is headed to the all-important Indian market.
