My 2 s 23 phones are not opening apps, or sending messages without great delays, sometime just up loading or downloading forever, started with last update of phone. Makes it useless to try and read news, send photos, text, just sits and twirls.
Go into settings- connections- mobile networks. Do you see Network Modes? If so, select it and make sure you are using Global Mode. If you don't see the Mobile Network option let me know and I will send you the information on accessing it another way.
The update caused the network modes to change. This can't be fixed within the settings menu.
• Open the Dialer app on your phone.
• Enter the ##4636## code. (also, the codes "##626*" and "##786#" may work for your Android).
• Enter into the Service mode > Tap on the Device information option.
• Scroll down to Set Network Type.
• Pick the Android preferred network type you'd like to use. (NR/LTE/GSM/WCDMA)
• Now, tap on the Run Ping test and look for the radio option at the bottom.
• Check whether the radio it is turned on or off. Press the button next to it to turn on the radio.
• You'll be prompted to restart the device > Tap on Reboot. Keep wifi and all other connections off and mobile data on. Make sure you have an APN selected and are registered on the carrier network. The phone will do the rest. Allow up to 1h, but should be fairly quick.
They didn't do anything? Issues with calls, texts, and mobile data are typically within the carrier's realm of responsibility to resolve. This service is included as part of your monthly bill. One thing you could try would be Settings>General management>Reset>Reset network settings. In addition to rebooting your mobile network, this will clear all Bluetooth and Wi-Fi connections/settings and you will have to reestablish them afterward. If that doesn't work, turn off the device. Press and hold Power and Volume up buttons until the Samsung logo disappears. Using volume keys, highlight Wipe cache partition, and then power to select and confirm on the following screen. On the original menu, use volume to navigate to Repair apps, and then power to select. This will reindex all your apps. If these steps don't work, kindly reach back out to your carrier and speak with their advanced/tier 2 technical support. Have them open a ticket for you and possibly perform further troubleshooting steps.
