Extended pistons retract for a second when the world is loaded.
From MCPE-19086:
The extended state of pistons is not saved in the file, instead their state is recovered on the chunk load by ticking them with some delay.
In the screenshot shown above, the sticky piston is permanently powered and thus should never retract. But if you reload the world the piston momentarily retracts and triggers the dispenser containing a water bucket.
Original description:
When loading the world extended pistons that aren't in the same chunks has the player will retract for a second. It seems to effect 3 to 4 chunks away from the player.

After further testing, I have concluded that this bug is the same as MCPE-17464, where redstone components update upon world-reload. Some contraptions with pistons may update during world load and cause pistons to be momentarily unpowered, resulting in this problem. Closing this ticket as a duplicate.

Could you provide screenshots of the pistons that you have seen retract upon world load? It's hard to tell what is going on if we don't know what is powering the pistons. A world download would also be helpful.
Confirmed to occur in 0.16.0. (Tested on Windows 10.) I was loading my redstone testing world and could hear some pistons retract as the world loaded. It happens every time I load the world. Not sure if it happens to all pistons or not. Will need to do more testing...

I have found out that this is in fact a separate issue from
MCPE-13608.Attached screenshot & test world from
MCPE-19086.True in 1.0.4
1.0.5 affected
Confirmed. 1.1.0.8 affected
This got much worse for me in 1.1 update (win-10 PC). Previously I'd have the pistons retract maybe once in every 10 world loads. Now, it happens every single time.
1.1.1 affected win10 and honor 8
Still happening, 1.1.4
