Wifi+bluetooth performance drop

Watching YouTube in my GT-I9500 over wifi is usually a pleasant experience with a fast HD video buffering. However, after pairing my phone with a bluetooth speaker, my wifi performance drops dramatically. If only bluetooth keyboard and mouse are connected this signal drop is softer but definitely perceivable.
I did some digging and found pretty similar issues in other devices.
This thread has been very informative: https://code.google.com/p/android/issues/detail?id=41631
but I am still not sure if this is a physical and not solvable matter or if there is still room for improvements via software
So far, I only know for sure that Android 4.3 did not fix it (in other devices).
Have you experienced this? Any workaround or advice?
I hope this helps and thanks in advance
So say we all!! from my GT-I9500
Well, it's 2018 and Marshmallow has the bug just like Kitkat, and Lollipop did. Why haven't they noticed this in 5 years?

D802 does not want to wake up (backlight is active, but screen stays black)

After upgrading my 16GB D802 from a beautifully working CM 10 to CM 13 the following problem occured:
After the screen shuts off (either by the phone going to standby or the proximity sensor in case of phone calls), it takes several attempts to activate the screen (you see the backlight turning on, but the screen stays black, then you have to click the power button to go into standby and try again til it works; tapping and pushing the power/standby button to wake the screen up work equally bad)
I tried going back to CM 10. On CM 10 the screen activates and deactivates as it should, but I had problems with very very unstable connections to wifi and cellular (which I had not before). (Also: I was stupid enough to not have made a backup of the previously stable CM 10 installation.)
All in all, I tested CM 13, 12, 11, and 10. 13 and 12 have the screen problem and 10 and 11 have the connection issue.
For all testing I used TWRP and the hybrid bootstacks.
Has someone experiences similar issues?
I would greatly appreciate any help.
Thanks so far!
Kind regards,

Cyanogenmod does not seem to be the problem. I've got the same issues with e.g. Mokee (MK51.1) and the Turbo ROM (Turbo-d802-4.0).
Might the bootstack be the culprit after all? Is there something that could have been gone wrong?
I tried the (zipped) stock ROM: the problem remains
Edit:
Flashing the modem (with a flashable modem) solved the issue with wifi and cellular on CM 11.
Software or hardware
Hello, I have the same issue but in addition the device is extremely lagged. Although I am still with stock mod and no root, by the moment. Could you help me?

Green is when I applied a temporary fix, switching airplane mode on and off.

Some of your bugs are covered in Q&A section already. Please search for it:
-screen burn
-Battery draining in case of bad cell signal
How many screen on time do you get from the screenshot?
Do you have any comparison phone where cell broadcast work or mobile network is better?
