Sound

I have an iPhone 7 and my boyfriend has the new galaxy and I can hear him just fine but when he hears me its like Im coming through so loud the speaker cant handle it and Ive turned my sound down on my end but thats not helping have you ever had any complaints like this before and what can I do I used this app with the 6 and never had this problem weve used this app for a really long time and even tho it doesnt affect me I hate for him to deal with it I love this app its been super convenient especially when hes out of town
