Poor Bluetooth Connection

When connected to Car Audio system, the sound quality is as poor and pathetic as it can get. When i stream music via bluetooth from Mi4i to my car audio system, it sucks big time. Not even a single line is complete without breaks and issues.

Is there any solution for the same ?

Poor touchscreen latency?

Has anyone else found the scroll/swipe speed to be slow on the Nexus 5X compared to other handsets? Annoyingly, I can't find any settings for this.

The issue is global and not limited to one app. With pointer trails on, there is visible lag between my finger's input and what happens on-screen. I've never seen this on any other device.

Thanks,
Ian

Poor battery life due to constant notifications. Any fix?

Hello everyone, I recently picked up a fire phone. I am running the stock software but I used bootstrapper to downgrade back to 4.6.3 so I can install the play store and nova launcher. The battery life is atrocious and it seems to be stemming from the screen not staying off due to a constant stream of BS notifications that turn and keep the screen on. Some were from apps but most were from the system regarding wallpapers, lock-screens ect. I left the phone on the desk untouched and watched the battery drop 30% in a couple hours.

Has anyone else encountered this problem, and if so how did you resolve it? I could not find any setting that would allow me to stop notifications or stop them from turning the screen on. Thanks in advance.
