S4 couldn't enable wifi Bluetooth and hotspot, how can I do it?

[AC Question]

S4 couldn't enable wifi Bluetooth and hotspot

Sent my S4 phone to phone centre
They told me They need to reset factory due to software problem
I thought there's only some problem with wifi antenna thingy
Does it necessary to reset? Or it is a scam?

Re: S4 couldn't enable wifi Bluetooth and hotspot

Which variant do you have? Which carrier?

I would try to restart the phone first before doing a. Factory data reset
