Something is making my S3 wifi get stuck scanning constantly. This part seems to be a common problem; the weird thing in my case is that even though the phone is constantly scanning it is not refreshing the list of SSIDs. So even though I am home and it is scanning, it doesn't show my SSID or any of the SSID's in the vicinity. It shows a bunch of SSID's which it picked up at some point while I was out and it is stuck on them. Also, when this is happening it doesn't show the "remembered" networks which are not in range. Usually you see all those at the bottom of the SSID list.
If I turn wifi off then back on again nothing changes. It displays the same obsolete list of SSIDs and keeps scanning.
If I toggle airplane mode then the phone actually refreshes the list of SSIDs and it stops constantly scanning. And it shows the list of remembered SSIDs which are not in range.
Keep in mind that updating SSID's isn't totally broken. When I leave the house it's working fine on my home SSID. After I leave it is obviously updating the list of SSIDs for a while but at some point it just stops updating the list but keeps scanning.
Any ideas? I'm stock & rooted 4.3.
I feel like I've posted a million issues in the last few days. I recently got a refurb S3 from Sprint that is a complete POS. My old phone was rock solid until the power button crapped out on me.
