I've got a samsung A52 4g version for 3 days now which I'm using. After the android 12 update I've noticed that my 4g sign with the up and down arrow goes missing after 20 to 30min. It doesn't return even for a whole day. The data works perfectly and apps like YouTube and Facebook works 100% but no 4G sign or up and down arrows. Ive tried changing sim cards. Tried different network settings. I've done hard reset nothing. If I switch of data off and on again then it shows for 10 to 20min and then it's gone again. I think its the update.
Are you talking about 4G or did you mean 5G or LTE ..who is your phone carrier...are your sure your using the correct APN settings for your device and carrier?
