So I have this iPhone 6s po, GPP LTE siya (iOs 10.3) ok naman nagagamit and all pero recently lang, yung wifi connection niya, ok nakaconnect but when I try to open some apps like FB, Messenger, Twitter, Snapchat, IG etc bigla nalang naging unstable yung connection niya for example sa Messenger, it keeps on reconnecting siguro mga 30secs din siya magreconnect then ganon ulit after few seconds. I tried to reset the wifi modem naging stable naman for like 3mins then ganon ulit nangyayare sa connection ng phone ko. what should I do? Is it safe to reset network settings kahit na GPP LTE to?
