Phone gets really hot when opening mendix app

Hello,  Im having a problem with my phone when i open a Mendix app that me and my colleagues created. Im opening the app via the Mendix mobile app (V4.4.0) scanning the QR code. But after a few minutes my phone gets really really hot, while other phones running the same app are totally fine. So i thought maybe its just my phone but a buddy of mine has the exact same phone and this one gets really hot aswel. The phone that im using is a Sony Xperia z5. Does any of you experienced something like this before ?

We do want to give people a warm feeling, but this should not be the case ;)
