I hope to shed some light on this by sharing what we know about the issue and solutions that we attempted.
Background: We have installed about 3000 of these Samsung locks (P718 and variants of these) since 2015 and we do sometimes get “I am locked inside” calls over the years. Installation experience matters much more so (for this “push-pull” lock from Samsung). versus the traditional turn lever type of digital locks.
Issues and solutions
Issue #1: Unable to unlock from inside when pulling the handle but manage to unlock after a few times. This is due to installation issue where there is friction between the bolt and the strike (on the door jamb). Temporary solution: push door in with one hand while pulling the Samsung handle. Proper Solution: Adjust the strike plate
Issue #2: Unable to unlock from inside when pulling the handle but unable to unlock even after many attempts. We do see cases where the *bolt* is jammed so even if you have the mechanical keys , you cannot unlock from outside (because the internal bolt mechanism) is jammed up. Solution: get a + screwdriver and remove the rear lock body and plate so that someone from outside can remove the outer body and exposing the mortise. Stick in a ‘-’ screw driver into the slit (where the ‘ice-cream stick’ like shaft was) and apply force to forcibly turn to retract the bolt (note: may require a lot of force).
Issue #3: (mystery): We have heard of some users who solved the above problems after replacing the batteries and there are some posts in this thread that mirrors our thinking, that the mortise bolt mechanism went into an ‘in-flight’ state (that prevents even a manual pull to unlock). Cases from this scenarios resolved itself and the problem did not repeat (to our knowledge after). The sensitity to “in-flight” power loss is a mystery (perhaps to the person who designed the mortise.

Mine is DP728. I had the bad experience on Sunday. Unable to unlock from inside...Support center closed on Sunday. Managed to find someone and guided me to get someone to open door from outside using my PIN. One neighbor came to my unit and helped. After few tries, door opened. Was told such issue occurred only when batteries run low. But I just changed the batteries lesser than 3 months. There was no warning or indicator that batteries were running low. Agree is a potential safety hazard. If there's fire, I wouldn't be able to escape if this happened.

Hi Carlos, I have the same problems. Do you resolve the problems?
Thanks.

Hi Fábio, no, couldn’t find a way to fix it. But I noticed that the way you pull the door to open really mathers, I must always open it from the upper part of the latch, and use a second hand to hold the device. If you use just one hand to open without enough strength on inicial pull, the lock system will go into a mid status where it doesn’t back to lock status and can’t go further to unlock status, this is not visible but obviously the door lock stops working... It’s really boring and non pratical, but I’m used now to use both hands to open it, and I don’t live in USA so Samsung support is really bad here.

Don’t ever buy the push-pull models from Samsung. It’s a total fire hazard. The electronics can get scrambled by many scenarios: door slams (physical trauma), temperature shock (kids outside trying to burn your lock), etc.
The next lock I buy, I have to make sure I have manual override (to open) from inside. It makes no sense at all why the push-pull models have manual (key) override from the outside but not from the inside.
I hope nobody dies from being locked in. Meantime, I’m open for a class action to demand that Samsung recalls all push-pull models sold.

I don't think there should be any worry about the electronics being "scrambled". Slamming the door isn't going to hurt it. When is the last time kids were burning your door/lock? There are many ways to vandalize a house. Breaking a window is easier. Plus I believe this lock detects high temp and unlocks in case of a fire (inside at least).
There is no key override on the inside because pulling the handle from the inside unlocks and opens the door. The mechanism for the inside is very simple (level turns a pin which turns a ring in the mortisse and opens the door). Even if they provided a key for the inside, it would just do exactly the same as pushing the lever.
Pushing from the inside always works for me. However, from the outside I must push quickly and forcefully. If I don't, the lock goes into the state described above where it doesn't open (though above they say it happened when using the inside lever). Pulling the lever, then pushing forcefully does unlock it, but it makes me a little nervous.
