Well having broken my previous phone I am back to my Samsung Galaxy S4 i9505, that's right, S FOUR.
There is official Lineage support , and also an optimized Lineage15 alpha build.
Currently I am using an AOSP developer build of Android 8.1 on my 5 year old phone and it is still running perfectly!
I've got three Galaxy S5 in the family all running LineageOS 18.1 (Android 11) and still getting updated once a week. It runs really well and is the best of many Custom ROMs I've tried for this device. However, the (very) few hiccups include:
- VoLTE and Wifi Calling don't work (and unlikely ever to work on these older Samsung devices with Custom ROMs) so ALL mobile calls mobile calls must use the 3G connection. Aslo, with Lineage it probably won't ever work. In many countries this will become increasingly a problem as the 3G service is shut down to free up resources for 4G and 5G.
- While Android 11's in-built SIP does work excellently over both Wifi and 4G, there are two configuration settings which revert to default after every restart:
- "Make Calls with">"Ask first" reverts to the GSM SIM, and
- "Caller ID">"Hide Number".
Having tried Lineage 17 and Lineage 18 on the Galaxy S5 I can recommend this device
except if your 3G service has been already been shut down or soon will be. Used S5's are very cheap these days e.g. including international postage costing less than $US 50 on eBay to where I live.
