I just replaced a 1.6 GPF toilet with a American Standard 1.28 GPF
toilet. It received a 5 Star (best) flush rating by using a 2-1/8”
trapway and a 3” flush valve.

The first thing I noticed is that in order to get the full flush you
have to hold the handle down for a second, otherwise the flapper
closes too soon. I haven't had any problems, in fact the short flush
seems to work for liquids just fine, but it's a tad inconvenient. My
other toilet (1.6) needs just the tiniest push on the handle to start
a complete flush.

I called American Standard and they said that that's how they work.
Yes, you have to hold the handle down to get the full flush.

Anyway, I was just curious about other 1.28 GPF toilets. Same issue?

The other thing that I was wondering about was whether the small
amount of water being used is enough to move things along once they
enter the pipe. *Doesn't a 20% decrease in water mean a 20% decrease
in "flow force"?

Sure, the toilet flushes fine due to the large trapway and valve, but
what happens after the stuff leaves the fixture? Is 1.28 gallons
enough to keep things moving through the pipe?

My "dual flush" toilet tends to plug up on a big "dump", unless I use the longer
flush. I had the same problem with its predecessor, a 30 or more year old high
volume toilet, but it didn't have an option for a longer flush. If your drains
are unusually convoluted, you will likely have more problems.

The lesser flush seems to not push waste all the way out of the toilet on the
new one. The problem often shows up on the nest usage. I just use the longer
flush on big loads, and have no problem.

You clowns should try reading (assuming you know how) the
instructions. The whole idea is that the partial flush is for liquids
and the full flush is for solids.

I like the "boom" of the full flush...at least you know that it is
working properly and the bowl is clean. Saving water is important in
many areas so I guess these new toilets will be around from now on. An
instruction manual might be helpful though for the "old-timers" who
haven't adjusted to the new reality of water scarcity.
