My phone updated overnight. It was working fine then i plugged it in to charge and suddenly my data wasnt working. None of my apps would load. 

I restarted the device, toggled airplane mode, toggled mobile data, did a soft reboot, turned the SIM card on and off, reset my mobile network settings, reset my APN settings.

My phone only works on Wi-Fi. Is anyone else having this issue with this update?

These automatic updates, that's insisted, with or without permission, or a decision if I want it or not, have lost some of my Important family contact info. I called to Samsung, and naturally you get AI, Samsung wanted to incorporate a $65/month charge on my debit/credit card, for a mistake their UI update made and caused the loss of my contract information. I'm glad my card was declined

Im so glad Im seeing all of these posts. My phone is brand new and its all messed up. Only wifi and when I want to watch TV I have to shut that off and turn on Hotspot Mobile tethering. Its got so bad that everytime my battery died or I shut my phone on or restarted it, my debit card would be deleted every single time that they froze my card and won't allow it to tap pay and now my direct deposit can't hit my account. Also I live in CT, last week I took a Uber and my location was Texas. Im buying an IPhone tomorrow and getting new emails and phone number. Screw Samsung

I'm having the same problem with my phone since the last update, my data doesn't work and all my apps only work with Wi-Fi, some of my contacts were deleted and have to reinstall my debit card. I never had this inconveniences with prior upgrades, mine is a Samsung Galaxy A16👏

Hello @phoenix9826,
I understand how unexpected and frustrating it is to have your mobile data stop responding completely right after a system update, especially when you depend on your device throughout the day.
Since you have already performed extensive network troubleshooting, please try these additional steps to see if they help restore your connection:

Boot into Safe Mode
: Turn off your device, then press and hold the Power button until the logo appears. As soon as it does, press and hold the Volume Down button until the phone finishes restarting. You can review the official Samsung Support Safe Mode Guide for precise visual steps. Check if your data works in this state to see if a third-party app is conflicting with the new software.

Contact Your Carrier: Sometimes a major OS update requires a provisioning update or a new eSIM/physical SIM profile activation from your network provider.

Perform a Factory Data Reset: If all else fails, returning the phone to its default state can clear out deep software conflicts caused by the update. *Please ensure your data is backed up completely before proceeding, as this permanently erases everything*. Navigate to Settings > General management > Reset > Factory data reset. Review the details, tap Reset, enter your security PIN or password, and select Delete all. For reference and more detailed steps you can check out the official guide here.

Give these addiotional steps a try and let us know the results so we can assist you further if needed!

One UI 9 needed more testing unfortunately so it's a bit unstable. Just wait another month, (I know it sucks) and the new security patch should fix it. Technically the patch should be out by the end of this month so ig less than a month

My S24 worked flawlessly... Now it reminds me of my flip phone I had in 1980... But then again I am coming up on my 2-year mark so I guarantee you they're trying to make me buy a new phone and I might buy a new phone but it definitely won't be a Samsung...

I think a lot of people are going to leave Samsung products. I know im going to look for something else when I get another phone.
