[Ionic 4] Cannot read property 'call' of undefined

My app is developed with Ionic 4 and it is available on google play store but some users can use it because receive the error Cannot read property 'call' of undefined and no icons are visible,

The app is compatible with Android 5.1.1 and on my Galaxy Tab S4 it works fine, the screenshot shown below is taken on huawei Y6 (5.1.1 too) but other devices are affected by the same problem but with Android 6.x

On the huawei Y6 I have updated the Android System WebView from the play store but without results

How can I fix this? And most important how can I “detect” which device will not work?
