How could arise call recording issue?

– You might have another call recorder on the phone. Please note, technically 2 call recorders cannot work at the same time in an Android ecosystem. If you have one installed, you are requested to get it removed otherwise our application will have problems recording phone calls.
– Target device might have poor internet connectivity due to which application is not able to upload all call recordings in time.
– If there are battery/power savers or security apps with similar functionality (e.g., CM Security, Clean Master, etc.) installed, they will prevent our application along with other background applications periodically & prevent recordings and other data be uploaded in time.
