Ever since the update to Android 10 on July 1st, every time my tablet screen is switched off the wifi will also switch off on the tablet. I've been through all the settings including the developer options and I can't see anyway to stop this. I've reset my settings too, but to no avail. I've had to download an app on the Play Store to keep the wifi on.
I also have the same problem, i have 2 Samsung S5e tablets and it has the same problem on both devices.
I have tried everything to correct this problem but nothing works.
So I guess its watch this space
My issue is a little bit worse: it crashes. I have two AP with fast roaming. When I stay in a place where both AP are weak, android crashes. It never happened with android 9
my S5e just downloaded and installed the patch https://doc.samsungmobile.com/SM-T720/XSA/doc.html. initial indications are good- wifi has been on and stable for several hours.
Downloaded patch couple days ago......still had to toggle wifi on/off this morning to see any wifi networks after switching on😫? Seems to have have been stable throughout day, no problems coming out of sleep mode but, but problem always been intermittent.
Currently away for the weekend and I'm not getting the same wifi issue that I am at home.
I'm thinking it might be an issue with the SSID not being split on my home router. So it's picking up both the 2.4ghz and 5ghz and hitting a conflict. Do any of you have your SSID's split? If not, it might be worth testing.
