Oppo will show its first foldable smartphone at the Mobile World Congress in Barcelona in February 2019. The confirmation comes straight from Oppo's Product Manager Chuck Wang.
While he didn't disclose any specifics about the foldable phone, Wang has mentioned that Oppo will deliver a 5G smartphone in 2020 and will also aim to release its first phone with a display cutout in 2020.
Foldable phones will likely prove a key focus in 2019. Samsung already provided a glimpse of its Galaxy F foldable smartphone and is expected to give it more screen time at the MWC in February.
iPhone is a brand by Apple. So your answer to that is that it works on all networks...lol
I don't think they're working on anything... They haven't come out with anything really new since the i phone 6. All just more of the same with a much bigger price tag.
