i don't know what happened, but its not due to download through smart switch or other computers way, as this is a safe way to update. however i didn't tried but I can't say that it is cause any error. try to remember did you download any location based app or anything like that
you flashed your firmware by Odin or used smart switch? because this is the proper and recommended process only ... but at present I don't recommend smart switch because new pc version creating problems for everyone ....otherwise it's impossible that mobile data or wifi have better priorities than firmware flash as software update allaways needs stable carriers otherwise software loop hole may be come ....why saying because this August security patch i have installed over smart switch only then i noticed dangerously battery drain...after that I flashed that firmware from Samsung service center now its fantastic...and after all samsung service center use odin only because it's their official software
do one thing...whatsapp to samsung in that number which they have given in notice section....in this covid situation they are providing technical support team to receive your device from your home if you will allow them 👍 it will take 236 rupees otherwise it's free within warranty period of device
yes you are right..not possible every time to go service center....but i am now fears about software update by samsung...because most of note9 even recently note20 also gone just after simply install software ....samsung provides non A/B partition type Ota software not like other companies hence firmware flash is only proper process bro ....thatswhy google mandate must to give A/B partition type Ota from android 3.0 it's compulsory to every companies
i don't know about what an A/B or c partition but i know only that this is practically not possible to go service centre to get software update and pay for that it is not good at all. and why not samsung inform us to do so? and why at software page telling that updatw through WIFI. why? if samsung knows these things then should inform us. but actually it clearly mention that use wifi to update. so my question is i should listen samsung or others view which is not officially proved?
