Speakerphone not working with dialer apps from play store, works with stocker though

[cannabiscure]

I prefer a good smart dialer, and am quite fond of True Dialer I think it's called. Well with the OnePlus 5, the speakerponhe option does not work, you press speakerphone it just stays in regular earpiece mode, will not activate speakerphone. I tried other dialers and had the same problem. The stock dialer works fine on speakerphone. It seems like a permission is missing or something? Can anyone else tell me if their phone has a working speakerphone with aftermarket dial apps?
