What everyone expects is that it will at least match the 7-year OS and security patch updates that Samsung's tablets have. It would be a tough competitor and would likely sell many more tablets than its current tablets, which only have 4 years of updates.
OnePlus has now announced its plans to present the OnePlus Pad 3 globally on June 5. The tablet is expected to be similar to the OnePlus Pad 2 Pro which launched in China recently and will launch across Europe at the aforementioned date. Details of a US release remain unknown, however.
