For me, it's the HUAWEI honor 7S. Been using it problem-free for almost a year now. Although it's about the cheapest of the HUAWEI models, so far, I'm quite satisfied with its performance.
I'm currently using Samsung Galaxy S10 Lite 8/128. A very successful model. Performance plus great camera and not expensive
Iphone 11. Everything is A+ about it in terms of functionality, appearance, design, etc.. the only issue is the fact that I chose Sprint as a carrier lol
I have a Vivo phone with an Android operating system. It runs extremely well and has a good camera and battery backup option.
