regarding apps deleted automatically

[GOLUSURYAWANSHI1]

In last 5 days i am noticing some apps deleted automatically on my phone Samsung on7 prime like Facebook lite,ludo king,vlc player,uc browser etc. 

I don't know what happening. When i was search particular app it's show for again install like when we download new app from play store. 

I think it's hacking. Can you help me what's that.🤔🤔

My device also not rooted and i was not doing any illegal activities with this phone.
