I have unlimited data and don't care if data is used to download or update. I get the option to choose update apps via network BUT DOESNT GIVE ME THAT OPTION WITH SOFTWARE UPDATE!!!!! WHY ? is there a way to get around this! I need to do my phone's software update! I have a SM-A5 16U
I didn't find my phone for the topic section so just picked that ???
because the signal must be stable to download sensitive file such as image file, boot file and firmware file. these files can not be corrupted otherwise when applying the update your phone may not boot. only wifi signals are preferred because of stability.
