I would like to request improvements to the system optimization on my Samsung Galaxy M35. The current One UI experience often feels slow and slightly unresponsive. When closing one app and switching to another, there is noticeable lag and occasional stuttering.

Another issue occurs when I receive a call or a notification. At that moment, the phone sometimes lags for no reason. Even the control center (quick settings panel) occasionally hangs when I swipe down from the top, which makes the experience feel less smooth.

I believe the UI needs better optimization. In the next update, it would be great if Samsung could improve the overall performance and responsiveness of the device.

There is also a problem with RAM management. Even without heavy usage, the 6 GB RAM remains almost full most of the time. Because of this, only about 1 GB of RAM stays free, which sometimes causes the phone to lag. It would help a lot if the system were optimized so that more RAM stays available in the background—ideally around 3 GB free—so the device can run smoothly without lag.

Please consider improving the optimization and RAM management for the Galaxy M35 in upcoming updates. I chose Samsung because I have been a loyal fan of the brand, but it is disappointing to see a new phone lag like this. If these issues are not improved, I may consider switching to other brands in the future. Even though some Chinese phones may have fewer features, they often feel much smoother in daily use.

I sincerely hope Samsung addresses these issues and improves the experience for users like me.

Samsung doesn't provide premium experience in the budget segment including FE models.

Only S&Z series provide clean and smoother experience.

“We are not asking Samsung for top S-series features. We were only talking about the mobile lag and hanging issues.” 😄

Okay, I think I can help you.
The processor is weak, so there can be delays in operations. Secondly, 8 GB of RAM is the minimum requirement. How much of storage does your phone have and are you using RAM+?

I have 6 GB of RAM and 128 GB of storage, and I haven’t used any kind of RAM expansion.

Bro.. 128 GB of storage is not sufficient nowadays. You should free up space by uninstalling the items that you don't require. That's the only solution left for you.😊
