Never had a single issue with Samsung or Pixel Phones. I dumped Samsung due to ads put on Android and their lacking software policies at the time, but they've since improved and I would consider them again.
My POCO X3 died after waranty period, manufacturing fault. samsung flagships are garbage with AI, dead bateries, green screens, LG never had water protection, slow cpu, no more app updatrs. nokia is piece off plastic.
A lot of smartphone makers have multiple sub-brands to address different market tiers and regions. These sub-brands don't always survive in the long run, and that's what happened with OnePlus, but it now looks like there may be another sub-brand on the chopping block.
