Changing default font needs to be simpler.

Just paid for Plus because before I tested this because I assumed there wouldn't be ANY WAY POSSIBLE for an email client in 2018 to NOT have default font selections on message compose. If you want to be taken seriously, this isn't optional...it's vital. Being sold on a product because of security and then failing to deliver a working product because of BASICS...unforgivable in 2018. Clean it up, learn what people actually WANT in an email client and you might have a chance. The devil's in the details.

I am reluctant to upgrade to a paid ProtonMail account because of the small font size in the Android app. When will an option for larger fonts be implemented within the app?

This works for me:
Settings -> Appearance -> 'Load classic theme' [so you can edit the CSS afterwards] -> in the field 'Custom theme' change

body { font-size: 14px }

body,
.pm_opensans {
font-family: 'Lucida Grande', Verdana, Arial, sans-serif
}

to the values you prefer -> Save

Need to be able to change default font and add a few to the short list available

Yes please....I have to change otherwise customers wonder if I am *********** when using size 14 font by default.

I am missing this feature too! Please add!

Please please please! I need the default font and size to match my default signature format, without having to go through multiple steps for each message.

agree

I would like this too. Most of my contacts what my emails in a larger font. So almost every time I compose an email I have to change the font settings. This really seems like an easy update.

Please, this matters

YES PLEASE!!

I just started using the ProtonMail Android app and the font size is a killer.

There really needs to be a setting for larger font size and pinch to zoom on any email.

And changing the system font and or display size just to fix this one app is not an acceptable solution.

On Android 7.1.2, ProtonMail App version 1.9.2, you can change the font size of an E-mail by changing the display size in the Settings App, in most cases.

Larger fonts

mobile font AND format is a joke...

Your font is too small, too difficult to use your service. May switch to another service.

YES absolutely. The inability to change the default font and font size is my biggest gripe about Proton Mail and is the one thing that makes we toy with idea of switching to another service or client.

I do NOT wish to use Apple Mail or Thunderbird. Hate 'em both. Proton Mail's web client app is really nice, but really needs this one improvement.

Zooming on Android enlarges the font, but the screen doesn't redraw, so the text runs off the screen.

Mobile app fonts are super small compared to the fonts in all of my other mobile apps.
