When sending photos through messages, the clarity can be reduced due to several factors, including compression, network limitations, and the messaging platform used.
The reasons are as follows:
1. If you send a photo via MMS (Multimedia Messaging Service) instead of RCS or a chat app, your carrier automatically compresses the image to save bandwidth;
2. Different messaging apps apply varying levels of compression to reduce file sizes and optimize delivery speeds;
3. If you send images over a weak Wi-Fi or low mobile data signal, they will be further compressed to speed up delivery;
4. Please check the following settings: Open the [Messages] app, tap the Profile icon in the upper right corner, and tap [Messages settings], then check if [Send photos faster] is enabled. If it is enabled, the resolution will be reduced for faster sending.
