Wifi Problem - SG Ace 2x (GT-S7560M) - Galaxy Ace II Q&A, Help & Troubleshooting

Hello everyone,
I'm in desperate need of some help here.
My wifi suddenly stopped working and im not quite sure how to describe it so ill post a photo.

}
But when the wifi does successfully turn on, it cant find any networks, it just keeps on scanning.
Please help.
Some additional information
Rom: Stock SG Ace 2x (GT-S7560M)
Phone is rooted.
I've tried everything I know that might have fixed the problem...this means factory reset (data/cache wipe), reflashing the stock rom and turning the phone off and removing the battery for a few minutes.

Update: This morning, I turned the phone off and took the battery out and left it like that for around 14 hours and when I put the battery back in the wifi was able to see networks and connect for approx 15 seconds, then it turned off again. Halp please..

I noticed that removing the battery for prolonged period of time would return the wifi to a functional state for at least 1 minute before all the networks disappear and it cant connect to the wifi again.. what do you think this means??

[Q] WiFi not turning on and other problems

A relative has recently given me there Note 10.1 2014 LTE (Model number: p605) which is currently encountering some issues, in the hope that I will sort it out for them. The issues are all to do with the WiFi.
The device has absolutely no modifications, and running the stock ROM. Here is a screenshot from the "About" section:

}
The problem is that WiFi sometimes refuses to turn on. You slide the toggle, and then it just turns grey:
After a minute or so, it will then return to the off state. The funny thing is, rebooting the tablet will temporarily fix the issue, allowing WiFi to be turned on again. However, once idling for a few hours, the issue will return.
My relative says that this issue never happened on JB, but only started happening once upgrading to KK. So my question is: have any other p605 owners experienced this? If so, how did they fix it? If nobody has experienced this, could anybody recommend a good way to fix this? I was thinking about a factory reset, but this should be a last resort, as they really don't want to loose all of there data!
Thanks for the help!

As you can see, uploading arrow is active but downloading arrow not.
I should say that I tried a lot of way to fix wifi but I couldn't. In addition I was connecting wifi before.
I wanted to try this rom Diamond Rom v7.0 L but I did not like it, after that I installed my previous rom Dr.Ketan Custom ROMV14 , I came out this problem.
I tried
*I install rom again
*I tried another rom
*I used N7100_wifi_fix_for_old_bootloader from dr.ketan
*I tried another wireless network.
*I tried *#0011#
*I made securestroage false from buildprop
WHAT CAN I DO?
HELPPPPPPPP
Try wifi analyzer. Just select the best channel over which your wifi gets more strength . It may help. I was facing some different type of wifi problem but it helped.

[Q] Massive cell standby battery drain when on WiFi Calling

Has anyone noticed this on their Edge? I'm running the latest software release including the OTA. On my previous phone the GS4, I never had the same issue with WiFi calling and this type of drain in the same location.
So far, I've tried turning off VoLTE, but I'll need a few days to see if it makes a difference. Any one else have other suggestions?

There is a discussion going here about this:

Some are saying turning off wifi fixes it. I'm testing it now
Turning off WiFI fixes the issue. This is what you should do: Turn off wifi, fully charge phone, restart.
Thanks, I'll give that a try. It should be a permanent fix correct? Hopefully there's a software update soon.
Ok...So here are my current stats. I had Wi-Fi off the whole time. About twenty minute phone call, web browsing, about 1.5 hours of audio streaming with screen off.
I am okay with this and think it will just get better as the phone settles in.
Lost about 8-9% overnight while sleeping.

Wifi drain on Marshmallow

Hey guys. I have a M5 dual, Android 6.0, unlocked BT and rooted. Since I updated to 6.0, my battery stands for less than one day. It used to last at least 2 full days.
Looking at the battery usage, Wifi seems to be the problem. However, I'm not using wifi at all. For testing purposes, I disabled wifi, wifi scanning, and location is set to device only mode, but it still reports that Wifi is eating more battery than anything else.
The only way to stop wifi from appearing in the list is setting the device to airplane mode. Does anyone know what it could be?

Ive disabled adaptive brightness and wifi scan and now the battery life is better.... But not even close to 2 days life
I kept looking for a solution and I found one that worked at least for me. It's worth a try if you're having the same issue with WiFi being what drains the most battery life.
Settings, backup & reset, Network settings reset.
This will wipe all your network data, including your stored WiFi passwords. If you had to download any configuration data from your carrier to make your 3g/4g work, you'll have to download it again.

Android 10 Update Bug Screen Flickering

Have a look at this ...
scary :laugh:
https://youtu.be/2K6OfvVCSus
My 835 did something similar the first "real" restart after Android 10 got installed, went on for ~20-25 seconds I would say, then I pressed the screen on/off button twice, all came back and I could unlock the SIM and continue ... hasn't happened since ... but was indeed scary
Marcher
I had the same problem too. Another reboot cleared it.
Didn't have this issue. But I noticed new battery settings and turned on the "protect battery" feature and now seemingly my sot has improved by a crazy amount I'm not sure if it's a bug.
The feature basically just makes it so your battery won't charge higher than 85%, and then when it says 100% after restart, it's the same as just 85% before. I can't post image for some reason, but I'm currently at 53 minutes of SoT and I'm still on 94%..

Got the same issue randomly (twice since Update), thought itˋs Hardware(GPU) Problem. Iˋm going to do a Clean Android10 Install if i have the time to.
