I have been considering replacing my nearly 7 year old iPhone (although very reluctant) and I was checking for options. Really the only phone that caught my eye was the Sony xperia 1 V, but I found no information about how to degoogle and lock down the device. I really like the features and the built in camera apps, etc. Is there a way to degoogle the phone without loosing the funcionality/ease of use?
De-googling inherently causes functionality loss on Android because Google provides a lot of basic services via things like the Google Services Framework. It might be best for you to buy something cheap (secondhand Pixel?), install LineageOS, and then see how you like that before committing to something costly like an Xperia, especially since you're coming from iOS.
The only functionality I've lost after migrating to a Pixel with GrapheneOS is the Android Device Policy (aka Work Profiles, the spyware your employer requires to use certain work apps)
Quite a lot of apps cease to provide real-time notifications/messages, if they work at all, when Google Play components are not installed under GOS. At the very least, Google Services Framework is required for many mainstream apps.
Isn’t there maybe a way to keep the factory os and selectively disable google services. Sort of no-script style? Not too familiar with the android ecosystem tbh, other than google is on top of the food chain, haha.
You can use Universal Android Debloater (updated fork here) to remove some applications, but it's nothing on the level of a custom ROM. If you are really set on the hardware of the Xperia 1 V then I would recommend taking a look at this guide, written by @TheAnonymouseJoker@lemmy.ml. It has some advice for how you can achieve greater privacy on a non-Pixel Android device.
In principle, one could probably do this to a rooted phone by removing all the Google apps, and all the Google services, and giving up the other apps and services that depend on them. It would be a nontrivial task, and the steps would likely be different for each phone model (and possibly each OS version). I don't know of a project that does this successfully. You might try searching xdaforums.com for someone who has done it.
However, I wouldn't depend on Google services staying disabled when Google still controls the OS.
IMHO, it's safer and easier to replace the entire OS.
The 1 V is officially supported by LineageOS. Installation instructions can be found here.
EDIT: I will add that support for this device is quite recent, and it is still very expensive even second-hand. You are relying on a volunteer maintainer who makes no commitments about how long they will support the device for, so I think it's financially risky to buy the device purely based on it having LineageOS support now. You might want to consider the Xperia 1 III, which is two years older and significantly cheaper on the seocnd-hand market, but is otherwise quite similar to the 1 V. It has also received official LineageOS support for a longer period.
All the Sony Xperia phones consistently & eventually make it to LineageOS mainline (so LineageOS for microG support too), but these ROMs don’t tend to come until near then end of a device’s 2 year warranty. I would assume that this is when they get cheap/used enough that developers can get their hands on them. Sony provides all the tools to unlock so it isn’t difficult or locked behind some centralized server for unlock keys. However, the nice cameras the come with… well you need their proprietary app unfortunately or the camera becomes a plenty bad device with the default LineageOS software.
On the plus side you get to support the only brand still shipping flagships with microSD, a headphone jack, and the ability to unlock bootloader (bonus the the 5s are <6" screens which is rough to find smaller phones now). Google Pixels won’t get you a headphone jack or microSD & Asus Zenfones don’t have unlockable bootloaders.
I have an xperia 1 iii running LineageOS w/microG and I was able to get and install the sony stock Photography Pro, Cinema Pro, and Videography Pro apps, however several features of these apps are missing, such as the ability to do panorama shots and other stuff.
DivestOS is the most degoogled (removes the most proprietary blobs) android ROM. See if your device is on this list: https://divestos.org/pages/devices
Yeah, any security focused android ROM won't include root because it breaks the android security model. Breaks the ability to have secureboot and system safety checks by apps.
Isn’t Sony far worse than Google in locking you into their platform and basically stealing your data? They gutted Helldivers and thru all their players under the bus by adding a PSN account requirement retroactively, even in countries that didn’t have the service. They only backpedaled because of the massive negative backlash. They have a history of installing root kits and treating their customers like absolute trash. And you want to go with them?? Yikes.
You are way better off getting a Pixel and then liberating it with Graphene.
