Accidentally deleting/saving activity by swipe! GARMIN: Please make one more step in-between pause and save/delete activity!!!

Can't really help you with the issue other than suggesting that you submit this as a request using the Share Ideas form.

You do have a slim chance of recovering those deleted files as long has you haven't used the watch too much since the files were deleted - how do I get my activity back if I delete it?

yeah, I've submitted similar request myself a while ago for Vivoactive, hopefully they would rethink the way how to control pause of activity a bit, maybe physical button confirmation.

I also have this problem and it is a NIGHTMARE. I have done the same as you and submitted a request on the 'share ideas form'. If I could I would badger Garmin every single day until they fixed/changed it. It really is the biggest user oversight of the GarminVenu.

Maybe that's a planned behavior to convince us that buttons are better than a touchscreen? ;)

+1

I know the screen sensitivity is is a bit messed up sometimes --  I am not questioning that.

However, if you like operating the watch with buttons, why did you get a Venu 2? Isn't every other watch Garmin sells operated with buttons.

Nah, I love touchscreen and that was a conscious choice, I know about advantages and disadvantages of buttons beforehand.
Also the watch has unique set of features necessary for me, the only other option which would have it would be Fenix which I wasn't ready to buy at the moment.

So as long as Garmin could do something about how pause works that would be great.

This thread is far less active than I would have imagined - this is horrendous human engineering, with an almost trivial software fix - perhaps new EPIX users will pile on to supplement us lower-budget VENU users. I have either saved or deleted a run/walk activity by some accidental screen touch about 5 times so far, generally by a shirt/jacket sleeve while the activity was paused (notice they were smart enough to require a button press vs. screen touch for pause/resume?). I've contemplated writing my own RUN activity to get around this, but there's just so much to have to re-invent that I don't think is available in the public domain. A touch screen IS GREAT for scrolling through options, selecting an item from a list, changing data screens, re-arranging lists, etc., but it is NOT a suitable interface for making irrevocable decisions to save or delete an activity. The developer of the breathing exercise activity demands a button press to confirm deleting one of those activities; how did the run activity developer miss this problem? The breathing exercise activity doesn't ask for a button press to confirm activity save, but those activities have a defined end, while run, walk, hike and similar activities need the user to tell the watch that the activity has indeed ended.
On a peripherally-related topic, I hate that the RUN app "auto saves" the run when it's been paused for a while - it makes it virtually impossible to take a 20-minute nap during an ultra race and maintain a single continuous track. (I concede that it asks if you are ready to save and allows you to extend the timeout, but A) in the absence of input, it decides to save; and B) it's the same human interface where the touch screen is used to accept the irrevocable decision to extend the timeout or commence the save).
I know some have asked if the RUN activity couldn't "resume" a previously-saved activity, but I'm on the developer's side with that one as being "not worth doing".
Again, maybe new EPIX users, who've paid a lot more than us VENU users, will have voices more easily heard on this topc.

I will be an Epix user soon, but I think that I will not have such problem because I will set the touchscreen off during activity

This should be the default setting on an epix. This is the way it is on mine and I haven't changed anything.
