I found this solution on desktop https://youtu.be/goMrvrcBh90. There must be a similar way on mobile, I just need to access the right files or know how they are called there..

@ginger1984 The problem is, I had my sync on and it never synced everything, no matter what. And as I said I couldn't really back it up, because of memory issue. That was in fact the main rason why I made the account. I've only ever had Opera for mobile.

Today I accidentally deleted all my opened tabs on my Android tablet. (Tried to delete my passports and cookies, forgot tabs and history were preselected) I thought I would retrieve them from my synced account but of course for whatever reason it synced just 90 out of all my ~250 I gathered through many years(most of which I regulary visited, some were sort of like history of my train of thoughts), and couldn't really back them up, because of self filling memory issue. I tried to use "restore recently closed tab function, but it`s not showing up anymore. Now I don't know what to do, because I don't want to overwrite anything, Or risk restarting the device and loose some retrievable data.

I would be insanely grateful if anyone could share any knowledge if there's any other simple way I didn't think of, or any programme with which I could restore the lost session, or maybe find some normally inaccesible files where all that data was stored I'm ready to risk my device If I could only restore all the tabs chronologically, including the search history of each (left-right arrow)

Thanks in advance
