Android 6.0.1 Marshmallow Update

Here are some of the issues I have encountered after updating Z958 to Android 6.0.1 Marshmallow:

1. It won't accept 64GB SD card. Previous version can if it was formatted to FAT32.

2. Sometimes the ringtone won't sound for incoming calls. Need to restart.

3. Some apps won't work correctly..such as Power Amp.

To Whomever, I missed out on the 6.0 update on my zmax2 because the phone wasn't active at the time. I'd really like to get the update though.. I think (?) The problem is.. well "possible prob" is, I'm on the Straight Talk byop plan using an at&t sim. Anybody have any suggestions.. that do NOT involve dealing w/ ST customer service? Thanks

This ringtone won't sound for incoming calls unless I do restart issue is getting on my nerve. This could be a good phone except for this issue. Same problem on both Lollipop & Marshmallow.
