Which smartphone can you recommend to me - good camera and fast?

Are there right technical experts who are familiar with the latest smartphones? I'm looking for a device that can:

- Very sharp and colorful pictures, even in the dark and good zoom

- Fast response time and generally speeds up / opens apps

- 3.5 mm jack for headphones

- High resolution display and good speaker

- Under 500 euro

What I do not care: size, battery, color, fingerprint sensor, notification LED

I was thinking of the Huawei P30, but I'm still looking for alternatives. I'm basically only interested in Android, Samsung is quite expensive and seems to have diminished the quality of the camera. Honor I have had bad experiences and I'm currently unfamiliar with other brands. Can someone tell me if he would recommend the P30 and which device comes close?

Do yourself a favor and buy yourself a real camera. Even the "cheapest" cameras with MFT or APS-C sensor are far superior to any expensive high-end smartphone in terms of image quality, especially with regard to low light.

Also, most smartphones have no real zoom, at most a digital one. However, only the image is electronically enlarged, which greatly reduces the image quality.

Otherwise, you can of course synonymous with mobile phones reasonably good pictures without much to understand it. I myself have no P30 but reviews after it seems to be quite good.
