I can't hear my friend voice

I can't hear my friend voice
=> Android 9, 10 disabled the call recording feature. This is the reason why your own voice is good but the caller's voice is very weak in recordings. No matter what recorder you are using in the market the result is the same. You can test and confirm this fact.
I have checked the Android source code, Google added new limits to block the call recording feature. It is IMPOSSIBLE to bypass the limits without root. So to fix the problem root is the ONLY way to go.
If you root the phone Boldbeast Recorder can fix the problem perfectly, you'll get crystal clear recordings at once. If you don't root the phone there will be no solution in the whole world without doubt unfortunately.

Also the contact number or names does not show on the call recording list. It's show only "unknown"
=> Please install Boldbeast Recorder from https://www.boldbeast.com/android/call_recorder.html directly to overwrite the version in your phone, at once the telephone number and contact name problem will disappear.
Why? Please see [007] in this page http://www.boldbeast.com/android/call_r … oting.html to know the reason.
Don't uninstall the app then reinstall it. Instead please install and overwrite it directly, so that all your settings and recordings will remain unchanged.

the autospeaker turned ON
=> Please disable the option "Call Settings - Fix Recording Issues - Auto Switch Speaker On" in the app.

I send email to app administrator so many times but nobody contacts me
=> That's because you just sent the email template to me without a single word of yourself. Basically this means "I don't want to tell you what the problem my phone has, instead I want you to guess it". This sort of emails were ignored directly.
