The protective sleeve is certainly no life insurance for all types of crashes, the smartphone should unfavorably fall on display, for example, on a stone, so you have to expect a cracked screen.

That alone is a reason to use the cover, since the "naked" device is all smooth, slippery and looks very fragile. Therefore, the use of the casing is worth in any case.
