Is there a definitive solution to the S25 Ultra Lag issue yet?

I know there are similar questions, but quite frankly, I'm tired of reading them all.  I'm tired of troubleshooting. How can something so expensive be the worst Samsung device I've ever owned and over them from the very 1st until now. 

I have an S25 Ultra 512GB. I do not have anything on the device really other than the essentials and of course all the bloatware. Still,  there is no reason in my mind why this device is so problematic. it's constantly lagging. I have to stop what I'm doing and go into the settings to optimize every few minutes. I can not have more than 2 or 3 tabs open in the web browser.  

it's driving me nuts.  I also have the S25.  only 128GB which out of that I only have 11GB free.  Yet on this device I can have 152 tabs open be uploading things and watching videos while streaming music and have no lag ever. I let the phone auto optimize while I'm asleep.   I never have to manually optimize.  

yes every thing is up to date,  all of the apps are up to date and when I say I have no apps I mean nothing other than what it came with and I even disabled some of those.  

This device is seriously on my last nerve.  I've tried all kinda of different troubleshooting tips that I've seen on other posts online and nothing works. 

If I return device I'm going to be charged all sorts of fees on top of the restock fee meaning I'll have wasted all the money I've spent thus far. My other option is to keep it and pay for a device that doesn't even come close to my expectations.  I have been a die hard Samsung user since the beginning, but boy all the sudden Google Pixels are looking real nice. 

P.s. The global locking of the bootloader, just another slap in the face. FIX THIS PLEASE!

The lag you're seeing isn't normal. I'm not aware of anyone else who has the same problem with the s25.

Have you tried just resetting the phone? It might be an app you have or something you've changed that's causing issues.

Oh and for the bootloader thing, I read somewhere you can contact samsung and request an unlock if you have proof of purchase. It's to stop stolen phones being unlocked and frp bypassed

Same, it's the fastest phone I've ever owned! I'm in agreement with some of the other responses... in where you bought it from and if it is indeed a knockoff and not an official device.

Easiest way to tell is...
Settings /about phone /status information and scroll until you see phone status... It should say official!1757909044125.jpg

That's a ridiculous statement! I got mine from Samsung and it's doing the same thing.

It's definitely not normal and I just got my phone last week and it's doing the same thing!! I'm taking it back to SAMSUNG.  They can fix the issue or hand me a new phone on the spot.  This is insane.  I took 6 screenshots waiting for my text message just to open! Insane SAMSUNG!!
