Bluetooth Low Energy is dropping characteristics

Question

I am currently working with a Bluetooth Low Energy device for work. On some phones I can stream data and the signals from our peripheral come in just fine. In other phones on the other hand several characteristics are dropped while streaming and the app does not work properly. This is mostly the case with Samsung phones. Any idea why Android Phones might drop characteristic values and how I might be able to get around this issue ?
