S21 slow loading apps on wifi

Hi
Over the past week multiple apps on my S21 ultra are running extremely slowly when connected to WiFi e.g. Twitter photos and videos not loading, BBC weather app opening slowly, Samsung members app not loading, etc. There is nothing wrong with my WiFi as all other devices are working fine, and the issue seems to go away when I toggle WiFi on and off though returns after a couple of minutes. All apps are functioning as they should when using my mobile data.
I have tried forgetting WiFi and reconnecting, restarting phone, starting in safe mode to no avail.
Has anyone come across this issue and are there any solutions to this?

I have a S21 Ulta and for the past couple months I've had the same issue!! Apps taking a lifetime to load including Google sites. It annoying!! You would think Samsung would send and update to fix this. I feel it's a bug in one of their updates that causing this issue.

I eventually resolved this issue via a second reset of my WiFi router. Following that it's been working perfectly so try giving that another go if you have done it already.

This problem just started with me on my Samsung S21 G+ ad my A51. Other home people are iPhone, not sure problems are reported. If I turn off the Wifi it is fine. 

 

I did a speed check from my 21 5G and i am at 500Mbps, so it is definitely not the connection, but I do not put anything past the router. The main router and extender were rebooted this morning but seeing a post about a 2nd reboot I will try again tomorrow while everyone is where they need to be and not here. 

 

I have uninstalled apps, cleared the app, did a wipe cache, and nothing resolves it. Seems hard to beleive it is internal, but I see how it can point to that..... maybe the phones are just jealous I ordered a 22 Ultra... ??? 🤷‍♂️

S21 ultra 5g. Same issue. I have been through the ringer and about to demand Samsung replace my phone. One of the apps that is not cooperating is a work apps I have very poor service at home and rely on all of my wireless features thai I spent $1300+ on to outperform. Not leave me frustrated with lack luster speeds. Oh and the speed test that rubbs it in your face. Thanks. 🙄👍 That won't do! I've done Factory, data, network and the 2 hour repair tool. Many times. Nothing. REPLACED MY ROUTER! which had nothing to do with it, because it acts up on every wifi network. I have very poor service at home and rely on all of my wireless features thai i spent $1300+ on to outperform. Not leave me frustrated.  Every tip and discussion string that i could read. No avail. It got tho the pointi was factory resetting so much, I quit customizing it. A waste of time.

I just picked it up from ubreakifix after a 4 hour complete software wipe and reinstall. still having issues with wifi. I broke out old note 8 and used it today while this was in the shop. What a complete breath of fresh air. I gotta say, it was realllllllly hard to go back to this paperweight! Why does the s21 ultra, the flagship phone fore that gen, make you think twice about putting your 2016, note 8 away again?  I also feel like this issue occurred about the time Android 12 was forced on me. The app would not let me put it off any further or let me progress 

I have been a loyal customer to Samsung since the first GalaxyS phone. My s3, I still use to this day as a universal remote for my entertainment system. Loved the note 3 even though i was constantly breaking the screen due to Phablet disease. Samsung has never disappointed until today. I even owned the spontaneous cubustion model a few years ago. (We don't talk about Bruno) Completely satisfied even having a phone that could explode at any moment. Thank you for making that recall painless.

This is obviously an issue. There are so many discussion groups with many topics about this issue.  People are fed up! We should have the option to downgrade our software. Remember windows 8?? I had no problem with using android 11 and did not want to update to 12 so quickly. For just this reason. Please give us the option to downgrade.

Just tried to check if my system was up to date. Obviously not! I just did a factory reset yesterday, but it reports not since February 7th.

Unfortunately our issues certainly appears to be different. I am starting to believe mine is the router. I will not have to deal with Verizon. I am able to perform normally on the Guest Network, I also have no issues on other WiFI's. Additionally my iPhone kid says he has some issues, not as severe as mine. Finally my old tablet has the issue and so does my wife's newer Tablet from Samsung. Absolutely frustrated.....but not sure it is on the Samsung side for me.

I don't face issue in wifi, but i face same slow app load issue in Mobile data. For anyone, who how issue in mobile data then

❤️🔥Solution🔥 : In "network mode" Do not select 5G network. Just go with "LTE/3G/2G" option. My problem with mobile data solved by doing this.

I'm having the same issue. Certain apps take forever to load, but websites load fine. The wifi speed is excellent and other devices work fine. I've tried rebooting my router multiple times with no luck. Definitely an issue with the Samsung Galaxy s21.

I'm also facing this issue. I noticed that it is happening since my last update. Some apps like banking apps, twitter,etc wont work on wifi, and when I switched it to mobile data, it works perfectly. But the moment I connect to wifi, it stops working. This is really annoying, sometime it works if I wait for like two minutes. Did anyone find any solution to this without resetting the phone?
