Using Signal with disappearing messages set to a really short time is probably the closest thing you can get. You can use a VOIP number from Cloaked behind a VPN to sign up anonymously.
Google is a shitty big tech corporation and wants everyone to use their garbage browser that collects and sells all of your data. Thankfully we have great solutions like Invidious and Piped that allow you to watch YouTube content without ever having to visit the ad-infested YouTube website. You can use these in combination with LibRedirect to automatically redirect all YouTube links, it’s awesome. No ads, no delay, no tracking. Just some free and open source software.
GrapheneOS is built to work with a locked bootloader, in fact, relocking the bootloader is a step in the installation guide. It’s not rooted by default and the GOS team highly recommends against rooting, all apps should work as long as they only require SafetyNet basic integrity. If they require full integrity, they won’t work on GrapheneOS because the OS has to be manually whitelisted by Google in order to pass the full integrity check. Most apps (including banking or government apps) only mandate basic integrity though, full integrity is rarely required. It should definitely work better than LineageOS.
For security reasons GrapheneOS doesn’t allow the modification of system files. You can achieve the same thing with DNS though. Either self-host a Pi-Hole or AdGuard Home, or use something like NextDNS.
A Google Pixel running GrapheneOS is your best option. Graphene doesn’t have any Google services by default, no bloatware at all, maximum privacy and security. It’s super easy to install, you can check out this video guide or just read their official documentation.

I recommend this after the install: https://youtube.com/watch?v=BymH90zFe30
That probably won’t solve your issues, but I can tell you a little about my setup:
I really hope that your issues get solved soon, I wish you good guck
Super pro tip: Do the same for any device that does not absolutely need internet access. Don’t buy IoT garbage that needs to connect to some cloud server. Use local solutions like Jellyfin for media streaming, Navidrome for music, Home Assistant for home automation, etc.
There are so many other things you can self host, Nextcloud for your files, calendars, notes and other stuff, Immich or PhotoPrism for your photos, FreshRSS for news articles and other sources that support RSS feeds, Pi-Hole or AdGuard Home for DNS. Definitely check out !selfhosted@lemmy.world.
I really like their VPN, in fact, I put my entire home network behind Proton VPN. I also use Proton Calendar for shared calendars, for my personal stuff I use a self-hosted solution. Sometimes I upload something to Proton Drive. But probably the most useful Proton product (other than Mail) is SimpleLogin which you also get Premium access to when you subscribe to a paid Proton plan. It allows you to generate an unlimited amount of alias email addresses and all messages are forwarded to your inbox, it’s awesome, I love it.
Nowadays privacytools.io has some really questionable recommendations. Check out Privacy Guides instead.
The Signal servers don’t do the encryption, it’s done on your phone. That’s how end-to-end encryption works. Also, Signal’s Server code is FOSS: https://github.com/signalapp/Signal-Server
From their website:
Snowflake is a system that allows people from all over the world to access censored websites and applications. Similar to how VPNs assist users in getting around Internet censorship, Snowflake helps you avoid being noticed by Internet censors by making your Internet activity appear as though you’re using the Internet for a regular video or voice call.
Did you know that Snowflake proxies are operated entirely by volunteers? In other words, a user gets matched with a random Snowflake volunteer proxy, which is run by a volunteer like you! So, if you want to help people bypass censorship, consider installing and running a Snowflake proxy. The only prerequisite is that the Internet in your country is not heavily censored already.
The classics: uBlock Origin to block those pesky ads and trackers as well as Dark Reader so I don’t get flashbanged everytime I visit a website that doesn’t have a dark theme
LibRedirect is awesome for avoiding tracking websites and replacing them with alternative FOSS frontends
Bitwarden to manage my passwords
Violentmonkey to load custom Userscripts
Snowflake to support the Tor network
there are many apps which use root access to increase privacy
If you mean apps that allow you to restrict permissions of other Apps, there’s App Ops, it works with Shizuku
customize the system
You can do some customization with adb/Shizuku but for some things you might need root. But I would definitely value security over customizability.
manage battery charging
The OS can do that pretty well
enforce firewall for apps and system
GrapheneOS has a built-in firewall that you can use to block network access to any app on the system.
block trackers
You can do that with DNS services like NextDNS
backup the system
GrapheneOS has a built-in backup solution
On average I get like an hour and a half of screen time per day. I use my phone to message people on Signal, I connect it to my bluetooth earbuds and listen to music or a podcast when I go for a run and I occasionally like to take photos. I don’t waste my time scrolling through TikTok for 8 hours like many other people unfortunately do. One week of battery life is pretty rare, but it has happened before. As I said, usually I get 2-3 days out of it when I it charge up to 80%. (charging up to 100% is bad for battery health, so I try to avoid it). I’m sure you will be fine. You can get a Pixel, install Graphene, try it out and give it back and receive a refund if you don’t like it. That’s the good thing about Pixels, installing a custom OS doesn’t void the warranty or anything like that. You can just revert back to the stock OS and everything will be fine.
I’ve been using a Pixel 6a with GrapheneOS and the battery life is just fantastic. Sometimes I can go for a whole week without charging, but this is the exception. But under normal circumstances, I still get like 3 days of battery life. You don’t need to be worried about that at all, battery life is even improved on GrapheneOS compared to the Stock ROM.
