A54 5G speed extremely slow after 6.1 update

[SamuraiDan24]

Since the 6.1 UI update, my cell internet speed has slowed down immensely. It is to the point that it takes considerable time to open a website. If feels like using a 56k modem and I can't rely on GPS as well.

If I connect to home wifi, everything runs smooth. Once I use 5G, I can't even use Maps app accurately. I have a Galaxy a54 and I've had it for 8 months, it ran fast until this last update. Please help! Will there be another update to address this? I've seen many complaints in the community forums with the same issue: lagging, slow internet, etc. 

I have done the "reset all settings" suggestion, and the phone worked great for 12 hours before going back to being slow. Please help.

Resettingvthe network settings in General Management is certainly a good troubleshooting step @SamuraiDan24  👌

Another is to try your sim card in another phone just as a step to help rule out a sim card issue. 

Another is > Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 

There is a diagnostic test tool found in your Samsung Members App. 

Sending feedback via the Samsung Members App too can help. 

Eventually a Samsung Service Centre can assess your phone.

Thank you very much, clearing the cache files was the solution! My phone is back to normal again.

If you try 4G networks, what happens with the performance?

I have found exactly the same and most of these answers to be unsatisfactory as I did all the obvious things like reset clear cache remove any dodgy apps it seems to be linked to the transitions and visual effects of the phone I turn these off in accessibility and it seems dramatically better...
