Iphone se wifi signal lost or to weak
I bought a new iPhone SE 2 days,then i bought a rubber case to protect my iphone SE.. My question why after putting on rubber case the wifi signal continues drop and almost lost and continues lost any time,but after i remove the rubber case from my iphone,the iphone keeps a strong wifi signal... why..?? whether the iphone SE can not be wearing any case to protect?? i really disappointed in this issue, i hope that apple company or in this comunities can solve my problem
