SaifulNasrullah if you want for just protection, you can just use normal case, CMF if much durable than normal phones, it has flexible glass that don’t broke easily, just get extra scratches, and if back broke , you can get replacement in just 499 inr, in service centre, repair cost of CMF if much cheaper, just don’t throw in water. I don’t know how, but they give display replacement in 2999, when display itself cost 7000.
