Get your SD card out of phone before trying to update

last time when i tried i had it out of my phone. but didn't work... btw does it have anything to do with the flight mode? i had it on flight mode last time because the instruction says that i cant answer calls. so i did that so that calls doesn't come at the time of updating.

i am stuck. after it has finished downloading stuff a dialogue box appeared saying kies firmware update has stopped working. i had two options one saying stop firmware upgrade and the other saying check online for solution. i went with the second option and the box disappeared. than there was another box titled "prepare for firmware upgrade"... it is saying "preparing firmware upgrade components". it has been more than half an hour but it hasn't been able to finish preparing. what should i do now???

About the firmware upgrading and sdcard problems, I've followed the two suggestions from here and the suggestion to modify cache size from here using SD-Booster (I set it to 2048, not to 2024) and everything is working ok. No more "SD Removed Unexpectedly"
Btw, uninstall and install Kies again to get rid of the error message. Don't forget that it's crucial to remove sdcard before upgrading firmware with Kies.

try to update using odin or you can update using OTA.
sorry for my bad english

I used to get the same error when I was on 2.3.6 KK1
After I upgraded to KL1, my problem was fixed.

Okay, I need some serious help with my phone.

After running on a stock ROM(but rooted /w TWRP), I decided that I wanted to install a custom ROM so that I could tether if needed. Well, big mistake. I wiped stock and accidentally wiped my stock backup when going to flash a custom ROM and so far I've tried XenonHD, Jedi X19, IllusionROM, and now I'm on a Stock-Tweaked. So far, every single ROM has caused massive delays in receiving SMS messages and syncs from stuff like gmail.
Data is definitely working, and i've tried both the epc.tmobile.com and fast.tmobile.com APNs but my phone keeps hanging when it trys to send some texts and, if I have texts "waiting" to be delivered to my phone, I only receive them once I turn on my phone screen or only if the screen is on. So what the hell is going on here?

Don't mess around with roms and flash the stock-root injected one via Odin.

Download goo to install latest twrp and then download stock ROM for your device, wipe first 4 options not internal or external and not otg USB at least 3 full wipes then flash stock ROM and wait and you should b good

I installed the stock rom via Odin and still having this issue. =/

It seems that if I go to 4G/3G/2G mode only the issue doesn't persist. Or at least not as much. But then I can't use LTE! =/

Call tmobile tell him you did a factory reset on your phone and that you're having this problem and they will reset the network on their side. This happened to me before in the past and a quick call to them fix my problem. Hope this helps

I just had the same exact issue in the Pittsburgh area. I had to replace my sim card and now all is well.

In Odin uncheck reboot phone before you start, reboot manually and flash twice.

Android 10 broke my phone's Mobile Hotspot Functionality.

Samsung Galaxy A50 (SAM-A505FN)
Android 10
One UI 2.0
Hello,
I updated my phone last night with the above updates and for some reason, Windows 10 now no longer sees my phone's hotspot.
Other devices in my home connect to the phone just fine. No updates were applied to my PC before or after the phone update.
I've reset everything on the phone multiple times. The network isn't hidden. Encryption doesn't make a difference. Changing the band doesn't do anything either.
The phone connects to the internet fine via USB and Bluetooth.
Does anyone know what could have happened and if there is a way to solve this issue?
Thank you.

After updating the device, did you boot into recovery mode and select the "wipe cache partition"?

I already tried this. No change.

Well, basically, after applying stock updates, if factory resetting and wiping cache in recovery isn't fixing the issue, about the only other option is to flash back to your previous stock firmware.
But, your issue might be caused by some other app/apps that you have installed. To test that theory, try booting into "safe mode", if the issue does not occur while in safe mode, that means the issue is caused by something that you installed.
Or, this issue may be caused by some other setting in your device settings that needs to be changed.
Did you update via OTA or did you flash the updated firmware via PC/flashtool?

No, I updated over my carriers update roll out. No flashing or anything. Just doing things legitimately.

Try downloading that exact update version and then flash it via PC. It usually does a better job than updating directly over the air.

Hi if you have any problems try to reflash to previous version via ODIN
