I have two Android tablets (Both installed Amaze file manager 3.3.4, via Google Play):
The previous one (ZenPad) has smaller resolution, but can always show the sidebar permantely; while the later one has larger resolution, but can't show like that, very inconvenient for a tablet:

BTW, the behavior of mouse right clicking on file should be showing the menu of it instead of back to last page, I think.
@VishalNehra i invoke you
Moved to 3.6 as we don't have bandwidth for this ATM


Sansumg Galaxy Tab S6 (SM-T860), issue seems disappeared at AmazeFileManager v3.4.3 , as long as adjusting system display zooming to minimum value?
Yes, it's basically dpi dependent. Display zooming changes the dpi.. let me see if I can define one for your device default value, shouldn't be difficult.
Device details:
model = Lenovo Tab 4 8 Plus (TB-8704X) android version = 8.1.0 (stock os)
resolution = (1200, 1920) ratio =0.625
system Font size set to Small(minimum value)
Portrait mode doesn't show sidebar permanently but in Landscape mode it does.

Tried but couldn't find the solution. @kuanyui Please use lowest display size for now.
@shuvashish76 I tried on 7" opened navigation drawer didn't really look good. Not much space was left usable.
