OnePlus Open, one of the popular foldable smartphones on the market right now, supports pen input. This news comes from a Reddit user Rashed341who posted a video of the pen working on both the main and cover screens of Open.

The only pen that works with OnePlus Open is the Oppo Pen designed for Oppo Find N2. This is a bit surprising because OnePlus hasn’t mentioned stylus support in any of its marketing materials for the Open.

There’s also a pen menu page in the Settings app, which suggests OnePlus plans to include pen support at some point but hasn’t announced it.

In both cases, users can start using Oppo Pen with OnePlus Open by pairing the two devices. Once connected, the stylus can Write, draw, and interact with the On screen like other stylus-enabled devices.

However, there are a few points to keep in mind before using the stylus with the OnePlus Open. First of all, OnePlus has not officially confirmed stylus support for the device; Therefore, it is possible that using a pen may damage the screen over time. Secondly, the Oppo Pen is not officially available in the US, so US users may need to import it if they want to use the pen with the Open.

All that being said, it’s a pleasant surprise that the OnePlus Open supports pen input. However, it is important to be aware of the potential risks before using the stylus with the device.
