Internal memory problem W10 Mobile [Lumia 735]

[GeRy Katina]

Hi everyone, my Lumia 735 updated a month ago and since then I`m having the following problem...
The internal memo (not SD card) is almost full (6.03 gb used of 7.28) inside it says;
* 3.31gb system
* 2.58 apps and games, but if I check whats installed it shows:
Whatsapp 249mb
Instagram 112mb
and then mail, edge, froove, fb messenger etc but they all are are all light, the most heavy are whatsapp and instagram, and if I count all the apps it doesnt weight 2.58gb as it says on the menu... I had to delete instagram and whatsapp so I can reinstall them and their weigh down.
But I dont know what else I can do to liberate space, I tryed using some programs but they didnt make any space :/
What can I do to liberate internal memory space so WP does not show me the space warning anymore? thanks!

Delete all superseded apps such as, Lumia Camera, Lumia Selfie, Nokia account, Storyteller,Photobeamer, MSN health, Msn travel and food apps.

Lumia camera cant be deleted, the rest are all deleted since the first day.

Why? I was able to remove it. Just connect it to internet and open the app, you will receive a notification to move to MS cam app.
