Alternative operating systems for older or low-resource mobile devices.

[tool50]

This is one of my first posts on the Vivialdi forums, I don't know how it is customary to do in this medium but here is my question, I have an old cell phone with a shortened battery life due to years of use and I have searched in search engines and I have found options like Ubuntu Touch and Lineage OS which are alternative operating systems to Android and iOS, but searching for installation methods I have found that there are lists of devices on which those operating systems for mobile devices can be installed and well my question is if there are ways to install those alternatives even if they are not on those lists, in search engines and tutorials I have not been able to find solutions applicable to old low-resource devices like the one I have, as I am somewhat curious and new to these issues I want to know if I can give that device a few more months of use, obviously I cannot install Graphene OS because that old device is not a Google Pixel. Any comments I will be grateful.

If your question is "Can I reanimate old smartphone to use is again?" The answer is not easy.

Ubuntu Touch and Lineage OS support only modern devices. There's postmarketOS, but many features don't work on this OS. You may search for custom ROM for your device, but this is not easy. You don't say what device you use.

You also probably want to ask "Will Vivaldi team support this old devices?" It's hard to answer this question, because Vivaldi is heavy dependent on Chromium project. You need Android 8.0 to install recent versionof Vivald. Firefox require Android 5.0. The best option for you it to buy cheap used phone with Android 8.0.
