Wi-Fi reception from the cell phone bad?

I have a Huawei Mate 20 and I have noticed for a long time that this cell phone very often has poor Wi-Fi reception, or sometimes even none at all.

No matter whether I'm with me, my parents or my partner, the problem is almost everywhere and sporadically every now and then. Sometimes more sometimes less.

It can't be because of the routers or the distance, as laptops, TVs and the other cell phones also work without problems.

Anyone have an idea or can help me?

The solution is very clear and easy to understand:
Either the device generally has poor hardware or something is wrong with the device (defect).

I think the solution that you generally emit such strong electromagnetic radiation in the ISM bands is unlikely and would result in the recommendation to go to the emergency room of a hospital quickly

Did you just completely restart it?

I've had the phone for over a year. Since I have already restarted it several times. 😂

It goes without saying that it has to be on the cell phone. That's why I wanted to know what you could do about it, in the form of an app or setting.

Since the error occurs I mean… Some never restart their cell phone for a year

How in the world should an app repair hardware?

I do not know if it is the hardware or if you can use an app to set anything that could solve the problem.

If you do not know that, you either have never had physics classes on the subject of radio - or you have not paid attention. 😉
These are basics that you learn at some point between grades 5 and 10 at school.

To put it bluntly: NO! You can't improve something like that with any app in the world.
