Happened within 3sec of your video shoot ? That's strange. Were you doing any heavy tasks/gaming just before this shoot ?
My phone totally empty at that time 😅. No games, no photos,
Brand new phone out of the box having this might create a big problem in a couple of days only. Report it to OP if that's the case & get your device exchanged.
I brought it from Amazon. And i contacted them, buy they deny to exchange.
Seriously 🙄 I also bought it from Amazon. They'll replace it within 7-10 days else you can take it to the nearest OP service center.
