The Lightning Network is NOT a soft fork; it's a layer on the bitcoin blockchain.
In fact the bitcoin blockchain has no concept of the Lightning Network at all.
My bad, I always thought LN as a soft fork for Bitcoin.
The more I know, I guess

Ladies and gentlemen, I have already written a subject for the purpose of restoring the porflain after deleting all the data from the telephone. This is why I will ask you here
In order to extract bitcoin, I first have to dump all the physical memory from my phone and then run applications to recover lost data on it? ( it was years ago and app from google store - bitcoin wallet / galaxy-s4)
If so, which application will be safe? or maybe i should do it manually according to a guidebook?
Recovering an old data are not an easy feat, if you don't know what you're doing it'd be best to give it to professional.
Lost/Deleted data are not technically deleted yet by your phone, rather your data are marked to be replaced by a new data.
How many do you lost inside that wallet? if it's a lot you might want to consider to bring your phone to data recovery service, they have the tools and expertise to deal with your issue.
DriverSavers are one of the top company for recovering data, they managed to salvage data from HardDrive that sank on the river
