OK, I'm gonna be the most specific as possible. I have an Alcatel One Touch 7042A, black color. This cellphone doesn't include the feature of changing the system font, as it isn't Samsung or LG. I wanted to change it, so I rooted my phone with an app which name is "Kingoroot superuser". The root was a success, then I downloaded a font changer app: "iFont: expert of fonts". There was a big list of fonts, I chose and downloaded "chococooky" which size is of 2.14 MB. I remember that, before applying the font, I had to select a change font mode, which are the next: "Auto (smart match), System mode (need root), Recovery mode, samsung mode, install mode, miui mode and huawei mode". I selected AUTO (SMART MATCH). My phone rebooted and the font applying was a success. Now comes the problem: Every letter changed, but letters in bold, italic and serif kept the default font. I don't know how to change it, I selected SYSTEM MODE in iFont again but the same. Can you help me? I hope I didn't confuse you with so many details :/
Your font package has come with bold, italic ...?
I think you need to download fonts for each type:
Font X, Font X Bold, Font X italic ...
