I am using Samsung Galaxy S21 FE for 6 months and I'm facing Carrier Aggregation issues. At the same place and time my Sister Who is Using OPPO F19 is getting Good Network Speeds and My Samsung Galaxy S21FE unable to send a message via WhatsApp. Especially indoors the carrier aggregation is very poor. Whenever I need to use High-speed Network, I need to get out of the house. Uploading and Message sending in Whatsapp are becoming a headache for Samsung Phone users. I noticed it on my old phone I.e Samsung Galaxy J4 and also on my mother's phone I.e Samsung Galaxy A series. Please note that so many people are facing the same issues with Samsung Phones and try to resolve this.
Check your Sim operation which may be slow, delete irrelevant video/ photo in your wh. up & restart your phone. Yeah Samsung device do have a slow network in some cases......Call the Samsung official.
