I've made the LR Camera (Android) my daily driver recently, but it really could do with touch-to-focus like the stock camera (and other camera apps). At least have it so that it centre-focuses on-demand, rather than at some arbitrary interval.
Thank you for the feedback.
I will pass it on to the concerned team so that they can work on this feature.
Just in case you have other awesome feature requests in the future, feel free to post them here: Lightroom for mobile | Photoshop Family Customer Community
Other users go there to up-vote features they want to see and our engineers lurk there to find issues that might be bugs and consider feature requests.
Thanks for posting your feedback!
I've discovered that this is an issue with the Camera API2 support in Oxygen OS on the OP3. Community Build (Open Beta) supports TTF.
