Another unpleasant discovery. There appears to be protective circuitry in the headphone output -- can't get anything like the levels of my previous droids. I've tried various volume boost apps to no avail... workarounds?

Could just be a limitation of the phone's headphone amp, maybe it's just not very powerful. The Savvy Z750 is a budget and quite low-specced phone. Or if it is deliberately limited in hardware, either way it's very likely there's not a lot you can do about it except possibly use an outboard amp.
 
I read that the headphone output power has been cut back since the early droid days to avoid lawsuits and such. Maybe this phone is an example of the new level and my previous ones were of the old level... just guessing. I don't think it's a power issue, line-level audio doesn't take much juice; less than powering the dopey little built-in speaker.
 
Pretty sure headphone output is a much higher voltage than "line" but I could be wrong.
I think it's probably a software limitation though that could be fixed with a custom kernel if there's one available :thumbup:

There's also this.

"EU acts to limit health risks from exposure to noise from personal music players."

Could be that ZTE are now making their phones comply, even if they're not intended for Europe.

What I get on aosp firmware is if I have something plugged into the headphone jack and I turn up the volume above a certain level I get a popup warning about the volume and I just have to tap "ok" for it to let me keep increasing the volume. It's actually a pain in the ass but there's probably a (root [lol]) way around it :thumbup:
