I have had my S7 Edge for about 2 weeks. 5 Days ago, upon restarting the phone... ALL google services stopped working over Wifi, but still work in 4G & LTE. Mail would not sync, play sore will not connect, play music gives a "connection error". Literally everything that involved my gmail account stopped working over WiFi. I tried the "tricks" eg: removing google account from phone, forcing stops, clearing caches and data. Some of these things work, sometimes. The same "trick" never works twice... and EVERY TIME the phone is restarted, we are back to square one with NOTHING gmail related working over WiFi... it's INSANE !!! I have never had this much trouble with a cell phone in my life. I want my crap S5 back. It had AWFUL battery life, but it worked properly. Any suggestions, or anyone else having this issue ?
