S5 loses passwords

[IndieKid]

I've had my S5 for nearly a year now but it has suddenly stopped remembering passwords for wifi.

It has affected all of the wifi routers that I reguarly use and even after 'forgetting' the connection and re-establishing the phone fails to automatically reconnect and I have to enter the password again.

I'm on Android 5.0 - model SM-G900F

Thanks

Hi @IndieKid I am sure someone will provide a more technical solution than this ...but a search of the android forums suggested removing the battery and sim and reinserting them ..fixed this wifi connection problem for a number of people. Worth a try..

It's a known Google issue that can affect any handset.
There are many theories but basically it's the file that saves the passwords that gets corrupt.
The only solution with half a chance of success is a factory reset (back up first) but unfortunately it's no guarantee.
If you just live with it for a while it usually starts working again by itself.

My Note 4 has a similar issue. It remembers most passwords but as I use many different wifi locations during the course of a normal day, there are certain places that I have to reenter the password every time.

Hi @IndieKid

Have you tried both suggestions from the members? Did you remove the battery and sim and saw if that worked? Alternatively, did you do the factory reset? I found this tuturioal that might help you for that

Let us know how you get on..
