I'm looking for a new suitable cell phone?

Since I notice that my LG G6 is slowly blessing the time after almost 3 years, I would like to slowly take care of a new cell phone, unfortunately I still don't really know which one it could be… It is important to me that the cell phone is not too big (the display, if possible, not larger than 6 inches), that it has a strong modern processor and that it has a very good camera. Whether rimless or not I don't care, only the price should be less than 600 euro. And it shouldn't be a Huawei phone. Who can recommend a good one?

I recommend galaxy a50 is great.
