[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:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
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!

Battery drain problems

My gpad the wifi version running Android 4.4.2 got problem in retaining battery. It drains about 4 to 5 percents of the battery when the pad is in idle for about 10 hours. The pad is new so i don't think is the app i downloaded that is causing the problems. It must be something have to do with the manufacturer. Are you folks having the same problems? May be i need to flush it and reload the android to get away the apps installed by the manufacturer. Any ideas? Thanks.

Sound better than average to me (I've had quite a few tablets&phones ... but only have this GTab for 2 days).

that is actually quite good,mine use to lose 10+%.got it to only lose about 2-3% by using clean master.just kill everything when i go sleep.give it a go.

Thanks will give it a try. There are just too much possibilities here. Need an expert to figure it out.

Download App Ops Starter from playstore. Look for apps that keep your tablet from going to sleep and turn off that setting. Also you can turn off their ability to spy on you.

what's the problem?

My tablet seems to be messed up...
I get constant app crashes even when just browsing, watching a youtube video is almost impossible due to lag and antutu reboots the device or the app crashes and when I get a benchmark done I get this....:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
That's almost as bad as the Galaxy Y....
My device is clocked at 2.0gHz(or 1.7 or 1.5 it does not matter)
Trust me I've tried every rom... from kitkat cm11 to stock 5.1 and it's all the same
Is this thing broken?

Restore stock clock speeds, then maybe someone can help? Revert to stock kernel and ROM, replicate. That would be the first order of business.

Save your stuff and perform a factory reset: delete everything, flash the latest 5.1.1 factory image.
I guess you have dirty flashed your ROMs too often ? Some leave thrash behind and some so called "developers" like to use some tweaks which are no use anymore ( and have been made for Android 2 or even older ..)
If your device behaves like this even in a 100% Stock environment, it might be faulty indeed..

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

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.

Question Universal GMS Doze Module

Anyone tried it on A12 yet? Does it still bring any battery saving benefits?

...for some reason I can't paste a Link here via Android Chrome :S

I've had it installed and didn't really notice any difference. Removed module after a couple days

I installed it. To be honest haven't really focused on battery, so couldn't tell u if it's helping or not. I always have a charger nearby, so never really have to be paranoid of it making it x number of hours.
On a side note, I know there were issues where it would not work properly unless you have the find my device service turned off. So may need to do that as well to take advantage of what this module brings.
