The phone's wifi sucks. Sometimes, the wifi is disconnected in every 5 or 10 minutes. Sometimes it doesnt even connect even if i am 2 or 3 meters away from the router. Even if it is connected , the download rate is 11 or 12 KB/s The internet connection is fine in pc, download rate being 3 MB/s . HUGE REGRET byung this phone. Wont recommend this phone to anybody.

I have to say (got today a new XZP): 5 GHz working better than any other device I have, but it's the opposit for 2.4 GHz.
My old Galaxy S5, the Xperia Z4 Tablet, the Galaxy S4 and my laptop all are far better in 2.4 GHz.
It goes so far that signal strength from the same AP is better with 5 GHz than the 2.4 GHz on the same place although it should be the other way around.
I also tested with two APs (AVM and Netgear) and also only running 2.4 GHz.
Result: I really like the phone itself and for everbody who is always close to APs it's fine, but really bad 2.4 GHz is a dealbreaker for me.

Could somebody with dual band AP compare 2.4 GHz and 5 GHz signal strength with an app like WiFi Analyzer and also compare to other devices who thinks his WiFi is working fine?

Wifi works great on mine too. Just because yours doesn't work properly, doesn't mean it's how the phone is. Do a little troubleshooting first before jumping to conclusions lol.

I don't know if it was to me or OP.
Speed and range is great in 5 GHz (got 450 Mbit/s what's nearly my full internet speed) and 2.4 GHz speed close to AP is also good.
But my problem is the 2.4 GHz range compared to all other devices I have.
Also do you get far lower signal strength when you place your hand around top left corner? I never had it noticable in such an extreme way.
And tell me what I can do else for troubleshooting than newest firmware, restart, reset, different bands, only 2.4 GHz, two APs?

No, I don't get lower signal strength when placing my hand around the top left corner.

To my understanding, the 5ghz's signal is supposed to be weaker than the 2.4. It's generally shorter because of the higher radio frequency. At the office where I work, we have dual bands. Luckily I sit near the router so I can use 5ghz just fine. :D However if I stray away from my workplace to lets say, fill up my water bottle, I end up reconnecting to the same network, just the 2.4 one since the 5ghz is too weak.

Then it's how it should be for you.
For me 2.4 GHz signal is weaker than 5 GHz testing with two dual band routers from the same distance.
Can you test 2.4 GHz in a place with 2/4 signal bars and place your hand than around top left corner and see if it goes down to 1/4 or 0/4 bars?

Magically it just worked suddenly without any obvious reason.
2.4 GHz signal was normally stronger than 5 GHz and 2.4 GHz distance was ok (not best, but ok).
Hope it stays like that.
Then at least the software is buggy.
