I am looking for a 4-inch Lumia phone. I've heard lumia 435's screen to be easily breakable. Is this phone sturdy? If not, which one among 430,435,532 is the most? I am looking for something comparable to 520.
Lumia 532 does not have Gorilla Glass protection, so it is more breakable than phones with Gorilla Glass 2 or 3. Lumia 535 has Gorilla Glass 3. Lumia 525 has scratch resistant glass.
So the answer would be, NO, Lumia 532 screen is not sturdy.
But if you use a soft silicone TPU cover case, it could protect your phone from falling onto the screen on flat surfaces.
