I had an older smart phone and it just barely worked on such apps. Now that most smartphones have better CPUs and such, I rarely hear of this issue. What is this phone?
Try end tasking all other apps first.
Every time I make a call on Whatsapp, after about 3/5/8/10/15/20/30 minutes the sound goes bad like I can barely hear the other person, voice doesn’t sound clear, like I’m hearing them through a microwave or something. I hang up and call back and it does the same thing after a few minutes. It doesn’t do that on regular phone calls so it’s not my phone, and it does it on WiFi AND 4G. I have no idea how to fix this and it’s very annoying. Any solutions?
