Couldnt find anything on obsidian not closing properly, so I searched the forum for why obsidian was indexing everytime in did start properly and I found, atleast in one post for the problem to be related to indexdb file(on Android). Didnt understand it much, but can anyone tech savy take a look at this comment here.
Also had tried re-opening the vault on my linux and android but I couldnt reproduce the issue
