Wifi can't automatically connect if the screen is off [i9505]

My s4 i9505 can't connect to a saved wifi hotspot when the screen is off. If the phone is suspended and i walk into a known wifi area it doesn't connect automatically, but only when i wake up it. wifi policy is set correctly and i have this issue only with lollipop aosp based rom (cyanogen, gpe,...). it works fine only with tw rom. i've tried 4.4 and older aosp rom and i haven't any issue. i tried different kernels and it seems the problem is no related to kernel but only to the lollipop aosp roms.
Other users had this problem but none of them solved the problem.

sorry for my bad english, anyway i hope you understand the problem.

[Q] Help flashing Alcatel C7 that boots automatically when plugging the USB

Hello,
During the past days I've been trying to flash my C7 with no success. When pressing power button, it turns on and displays the Alcatel logo but stays there, it does not load the OS.

I have tried to use SPtools to flash it, I have the mtk drivers installed in my PC. When I plug the switched-off phone to the computer it turns on and couple seconds after my PC detects it (I can see the preloader mtk loaded on the device manager); however, one second right after it is detected, it is disconnected as it keeps booting to show the logo and stay there. Obviously, if the phone is not detected I cannot use SPtools to flash it.

Any suggestion will be highly appreciated.

PS: I have also tried to connect to it with adb, and dump a ROM using sideload with no sucess, the PC recognizes it from the recovery but after copying the image nothing new happens on reboot.

Volume Notification wont automatically disappear - am I missing a trick?

Since Marshmallow I have noticed that if I adjust the audio in for example a video, the pop down volume notification wont automatically disappear unless I press the screen.

This is pretty annoying as this causes some videos to pause or other screens to pop up.

Has anyone else noticed this, and if so, is there a simple fix?
