Hi everyone new to the nexus 6 jumped ship from the Note 4 after months without root or lollipop. I'm loving the nexus 6 Roms but have come across some problems leaving me with only stock or clean ROM available. Aosp Roms ex. Euphoria, chroma. No voicemail visual or regular. Whenever anything happens with voicemail I get cryptic texts repeatedly. Verizon support was no help. I thought maybe it was a carrier issue. Cm based ex. Candy, cm12 unofficial. Bluetooth audio is highly sped up and skips around when connected in my car regardless of app. Both problems have been driving me crazy. Any help appreciated. TL;DR aosp has no voicemail, CMs audio plays sped up.
