RCS is a pile of garbage for many reasons. On Android, it’s locked behind Google’s proprietary, privacy-invasive Messages app, and there is no API for third-party RCS clients (like with SMS). The encryption is also implemented in that proprietary client, offering no transparency and meaning that it’s probably backdoored. No one should ever trust encryption software if its source code isn’t public. People should use actual private messengers like Signal, with open source applications available for all platforms, as well as all of the features you mentioned. The only thing it obviously lacks is SMS fallback, but it’s really unnecessary, because Wi-Fi or cell data are literally available everywhere nowadays.

Just use Signal. It’s private and secure, available on every platform (including desktop), you can send photos, voice messages and all kinds of other files.

Oh man, I just looked up the Xperia Z4 and noticed that it’s like 10 years old. Can’t say that I’m surprised that there are basically no ROMs.

I don’t recommend installing random builds from forums like XDA. GrapheneOS definitely doesn’t have an official version for anything other than Pixels, you might want to try LineageOS if you want to throw the tablet out anyway

Don’t let this misleading Wired article fearmonger you. I recommend this thread, which provides some nuance to this drama: https://grapheneos.social/@GrapheneOS/112967805820394815

GrapheneOS doesn’t include this, along with many other unnecessary carrier apps

It’s only compatible with modern Pixel devices, so unless you’re old tablet is a Google Pixel Tablet, you can’t install it anyway. But the installer is super easy to use (if you have a compatible device). It’s literally all in your web browser.

The GrapheneOS guys also explained why this isn’t nearly as bad as it sounds, and how Wired is simply fearmongering: https://grapheneos.social/@GrapheneOS/112967309987371034

The story isn’t nearly as dramatic as it seems. Maybe this thread can offer some nuance: https://grapheneos.social/@GrapheneOS/112967309987371034

I think the Pixel Fold might be the best option for a foldable phone, because (just like all other Pixels) you can flash it with a private, secure, open-source ROM like GrapheneOS.

Sorry, but this is really useless. I support the cause, but there is absolutely no need for this software. I think this community is meant for software that actually has a use.

That’s great

Does Google Fi allow for OEM unlocking (to install a custom ROM)?

Calyx is pretty insecure by default, it removes some default AOSP security features and is very slow to push security patches. And it doesn’t include any of the GrapheneOS security features like hardened SELinux, a hardened kernel, secure app spawning, hardened Chromium browser and WebView or hardware-based integrity attestation. It also uses a very flawed Google Play services implementation (microG) which requires root and has worse app compatibility.

It’s probably automatic

Using a device with no vendor-provided firmware security patches doesn’t seem like a good idea to me. Also, the Pixel 8a gets 7 years of updates. That’s plenty of time, and most people get a new phone after a much shorter time.

Bruh I’m just casually asking, what’s wrong with that question

What Magisk modules do you need to use?

GrapheneOS has so many advantages over Lineage, there’s no reason to use Lineage on a Pixel

Yeah I remember the OnePlus One like 10 years ago, it was genuinely a nice phone
