Custom ROM gang: puts off updates for three months because you can’t be bothered to actually download the package and re-flash it manually, and it might also screw up your user data and require a reinstall
Granted, this used to be a way bigger problem in the Kitkat/Lollipop days, when CyanogenMod hadn’t become Lineage yet. Nowadays OTA updates work pretty well, but occasionally it’ll still tell you to flash it manually.
The annoying thing to me is my watch. I wear my watch to sleep because I like to track my sleep and I like waking up to the vibration as opposed to noise. I have auto update on for my watch but it only will do it in the middle of the night while on the charger. I can’t tell it to do it mid-morning instead. So I always have to remember to manual update after putting it on the charger in the morning.
That’s so frustrating. Smart watches seem to be in such an experimental place still.
