I even wrote to spiegen to make case for f3 few days ago and they told me they might ^^. So you say it's confirmed now . Spiegen is my No. 1 too.I tried those nilkin cases before but I settled with the Spigen cases. I am comfortable with their rugged cases, sadly still not available for our devices until now and according to their facebook/twitter official page, it will be available within a month (( maybe today up to may )). Still waiting for the release and currently using free case from poco sad
Nillkin frosted is too stiff for me. It's not elastic at all. I bought one for my mum for moto gs5+ and it didn't even cover full phone on bottom. Hope that camshield I ordered is at least bit elastic. If not i gonna return it and wait for spiegen+1 for Nillkin "Super Frosted Shield".
Provides protection without the bulk, if you want some extra protection you can get a HydroGel back protector also.
The HydroGel protector is not too thick and Nillkin case should still fit right over it.
