FAQ

 

Do you support US bands/my country's band?

At the moment we do not, although we are actively working towards making a US phone with support for the common US bands. We understand this is something people really want and we are looking into it!

If we ship the device to your country, we support its bands!

(N.B. For Australia we only support Telstra!)

Do you support WhatsApp, Messenger and Signal? 

Yes we do! These also work with push notifications via MicroG or Google Play Services to ensure you get instant updates!

Do you support X banking app?

With the google variant many banking apps are supported. However there are a lot of banking apps that will not work on this device due to the Google Play Integrity check. As a good start - please look for your application in https://privsec.dev/posts/android/banking-applications-compatibility-with-grapheneos/

Note the above is not perfect however. We are working on a list of supported and unsupported banking apps.

Do you support Maps and GPS? 

Absolutely - the phone comes with Organic maps which supports offline maps and you can also download Google Maps

Do you support authenticator/2FA apps?

Yes we do - both FreeOTP+ (a generic 2FA application) and Microsoft Authenticator along with Authy are supported!

Will this device get regular updates? 

Yes - we have made many updates over the last few months including better battery life, improvements to our app blocker and the addition of MicroG.

Does the device support RCS?

Dumbdroid does support RCS on the Google Play version - please download both Google Messages and Carrier services from the app store. Please note RCS support depends on carrier support!

Does Android Auto work?

Android Auto does work - please use the Google Play variant for it to work!

Does Spotify and Apple Music work?

Yes both of these work!

Do USB-C to USB-C charging cables work?

Unfortunately, these do not work as the hardware cannot negotiate the right voltage. You must use a USB-A to USB-C charger

Do you support professional flashing/allow me to send you a phone to flash?

Unfortunately not, as this is time consuming and often the phones are irreversibly bricked when sent to us.

Do you support WiFi calling?

Unfortunately not at the moment! This is something we are actively working on!

How can the phone help me overcome smartphone addiction?

The 2.8 inch screen makes it quite hard to scroll through content for extended periods of time. It also comes with an App Blocker which allows you to temporarily or even permanently disable certain applications.

Is the device secure?

We make regular updates and ensure that we have the latest Android 14 updates. The userdata is encrypted at rest. However, if you are looking for a very secure device and have a very high threat model- it would be better to get an iPhone or Pixel with GrapheneOS as these have a dedicated hardware chip for the encryption keys. It's also worth noting that a mobile phone with a SIM card inherently gives away your location - we believe the best solution here is to minimise usage!

Can I make calls over 4G/VoLTE?

Yes – this is fully supported! As of a recent update, this works out of the box.

What bands do you support?

We support 4G on bands: B1/B3/B5/B7/B8/B28A/B; TDD-LTE B38/B39/B41

Can the phone be used as a Hotspot

Yes it can! I use this feature everyday and it works very well.

Do you support NFC/Contactless payments?

Unfortunately, the R77 Pro does not have an NFC chip so it cannot do contactless payments.
