Replacing my Samsung S10 - any recommendations?

Go with the S20. I have the S20 FE and LOVE it. As for the lack of a headphone jack, you can get an adapter for it like I did.

Fairphone 🤔
The 4 is going to be released

As an audiophile not having a headphones jack is a deal breaker for me. Now that LG is out of the market, the remaining candidate are Sony and Asus for me.

Maybe look at the Zenphone 8 (strong value) or Xperia 1 mark 3 (expensive).

There's a new promising codec (aptX lossless) coming for those who can live without jack but don't want any compromises on sound quality.

I had an S6, upgraded to S9. Simply fantastic line. GJ Samsung.
If you had an S series before, I would recommend continuing the trend. So either S20 or S21. That said I do believe S21 is the better choice if you can afford it ^_^

Asus Zenfone 8 seems like a good choice as it does have a headphone jack and comes with a Snapdragon 888

next time i go to buy a phone im gonna make sure it has a replaceable battery. we have the right to repair our electronics and i will never again buy a phone without a replaceable battery.
so my recommendation is to make sure your next phone can be repaired. some country's protect there citizens by forcing phone company's to make products repairable but not all.
my current phone sold in other country's has a replaceable battery but the same model sold in america can not be opened. i dont know what the down low is on your current phone or the one's your looking at, but the ability to put a new battery in should be the first concern of any intelligent consumer.
if anyone reading this lives in america check out the right to repair.

Google Pixel 4a with GrapheneOS (ungoogled ROM) for privacy & security if you can live without Google Apps.

Google Pixel 5a is pretty great it has it has headphone jack

If you want a flagship, take a look at Realme GT.

Excellent thread as i need to replace mine as well. Will a look out for the answers

Pixel 6

i got a poco x3 pro 8gb, cheap and powerfull

I replaced my old S9+ with the OnePlus Nord 2, loving it so far. Charges from 0% to 100% within 30 minutes. Very clean Android interface, none of that Samsung bloatware crap. Great budget price.

It's battery life isn't as good as some of its competitors. But it easily lasts a full day, so that's enough for me especially with the insane speed charge. I dislike its speakers though, so if that's important to you I'd probably look elsewhere.

pixel 6 is coming soon so it might be worth waiting for that

I've been using a OnePlus 7 Pro for over two years now it literally still handles like a brand new device, only the battery life is not what it used to be, but it charges pretty fast, so it is usually not a problem, so I would recommend the OnePlus phones, they're really good. The only thing that has disappointed me in the newer OnePlus phones is that they removed the pop up front facing camera... The battery life of the 9 Pro is nothing special, but you know, those phones charge insanely fast. Also since you're a Samsung fan, you'll probably appreciate the phone, since they use Samsung displays, and the best one Samsung can offer at that. The android install is pretty clean. From what I've seen the 9 Pro and Samsung Galaxy S21 Ultra are pretty much neck and neck. The Samsung is a bit more durable since it has the new Gorilla Glass Victus, while the 9 Pro has the regular Gorilla Glass 5. When it is down to the cameras - the back cameras are neck and neck, in most aspects. The only thing the Samsung is clearly better is the Zoom, while the One Plus is clearly better with its capability of recording 8K videos in 30FPS, with both it's normal and wide camera. The S21 Ultra can only go to 24FPS with a crop on the main camera, which pretty much makes the feature useless. The OnePlus can record at 120FPS at 4K for some cool slow mo 4K footage, while the S21 can only go up to 60FPS at 4K. Now, when we head to the front facing cameras, well the S21 just outright wins. The OnePlus is just having a very mediocre front facing camera that can not even record in 4K. The S21 has slightly larger battery so it holds out longer. However, the 9 Pro literally recharges a few times faster with it's 65W charging and 50W Wireless charging and the charger comes in the box with the phone. The S21 Ultra does not, you have to buy it separately. The OnePlus has better cooling solution compared to the S21 Ultra, so it tends to run a bit faster, not that you would ever notice that with both running a Snapdragon 888( Don't buy the exynoss version of S21, never do that), you'd mostly notice the heat that is more intense on the S21. So it's pretty much a personal preference for which one of those you'd chose if you had to go with them. But in all honesty at this time of year, I'd probably recommend you to hold out until companies start releasing new flagship phones, like the Pixel 6, who knows, Google might have it right this time.

I just got the S21 recently to replace an S7. (Yeah, it had been a while). The S21 seems very good to me, especially as someone who is already familiar with Samsung phones.

I wasn't thrilled about the lack of a headphone jack because I use my phone for music when I travel, but I got an adapter and I love it.

I suspect all of the top-end major-brand Android phones are pretty similar overall, but I think if you're already comfortable with Samsung and don't particularly want to change brands, you'd be happy with the S21.

Check Asus ROG Phone 5
