So Development mode in iOS has a way to emulate slow networks, Iโve used for testing several times and depending on what the application under test does you might come up with some interesting scenarios. There is now way to do that from a physical Android device as far as I know, as a workaround I would just setup one of the iOS devices as a hotspot and use that network to test Android
Now for those that want to test a website you can use Chrome Development tools that has a throttling option while emulating a mobile view
Just found a couple of tutorials that show where and how:
thanks for the reply and the great idea of using two phones to connect with each other and then to close the connection while using the other device! When I tested in different mobile networks I found so many issues, one canโt believe :D.
Thanks for the great resources attached to your post, they will help learners to go even further!
