What should I do if the handwriting of Samsung mobile phone becomes thicker?

1, want to change the font back, in fact, just press the volume button at this time, the font will change back. In fact, when you press the volume+or-,the font can be smaller or larger.

2. In fact, there is this option in the SMS settings, which is not checked by default, that is, the font size does not need to be changed by the volume button (this is the case with my mobile phone).

3. If you want to change the font size of SMS without setting the volume button, you can change it directly in the settings. Click the leftmost menu button (the one that lights up on the left of the middle home button) on the first interface where you enter SMS (not the interface with SMS content), select settings, and then check or uncheck them, so that the settings are successful.
