Fix Unknown Caller Name ACR | Call Recording Apps


I am going to write about how to fix unknown caller name problem in acr and other call recorder applications for android after Google has denied phone number access permission for all call recording apps. we are receiving lots of requests about it from our customers, they are facing unknown caller name problem from few months.

Full Working ACR Call Recording App

This is Google’s policy and only applies to the Google Play store. they are going to release fully functional version of ACR called “ACR Unchained” on other app stores such as Huawei and Samsung and keep required permissions for accessing phone number during the call.Unfortunately Google Play Store policy prevents them from providing direct apk downloads from their website.

How to fix unknown caller name?

Because of Google have full control on Google Play and Android security is being improved day by day. Google not going to allow these apps to access phone number during calls so call recording apps developers are bound to follow Google’s policy if they need to be in Google Play. but i have a solution for unknown caller name for your you today.

How it works?

As we all know that android apps developer must follow to google policies and keep apps updated as per policy changed to compliance with new Google policies. But in this case we know that previous versions application was working well. So we can find old version of call recorder app or any other app before the current version which is not working for us due to some changes in in application.

Android apps developers can’t leave Google Play store because this effect directly their earning from Android applications. Let suppose someone made a best application and selling directly from their website, will this work for them. no this will end up with failure because 99% people prefer using free applications including me.

So developers earning are totally depends on Google Adsense ads, so they are publishing apps on Google Play to get maximum downloads for their apps.

Installing working version of call recorder app

So we are also going to install old version of ACR apk to fix unknown caller name problem due to changes in new version of ACR apk. Before we move forward we must have downloaded old version of ACR application. if you still have not downloaded the application.

Installing an Android application is not a big deal but some people still don’t know about Android application installation process. we can install apps on an Android device via two methods. this first one is via copying apk file to internal memory and second  one is via adb command.

Update: Now we have fixed version with latest version on Galaxy Store , so you can download directly from Samsung Galaxy Store on your Samsung phones.

      If your recordings where already was unknown name then these will not be renamed. You should install from Samsung Galaxy Store to fix unknown caller name but remember this will work on future recordings not previous.
