HTC devices compatibility


I have developed an Android app using Estimote Android SDK and it works fine on my testing devices (Moto G 1st gen and Nexus 5) but I have tested also in HTC One and HTC One Mini 2 and the app can't find the iBeacons. Moreover, I have tried to find the iBeacons using the Estimote official app and they appear but after one second they disappear (while other devices can still find them).
Has anyone experienced the same issues?

I was facing a similar issue on Galaxy S3, with the device's Bluetooth stack crashing after a few seconds and the beacons disappearing. Couldn't find any workaround so far—if anyone knows anything, please share!
