Thanks for your feedback.
I'll wipe my phone, re-install LineageOS and see how things go over the weekend.
Hi,
I wiped my Galaxy S4 and re-flashed LineageOS.
Sorry, it took a lot longer than expected, as I had lots of data to back up.
This is how I've proceeded:
- I downloaded the latest official rom file (i.e. lineage-18.1-20230515-nightly-jfltexx-signed.zip) onto the external sdcard of my S4
- turned off the phone and took out the microSD card.
- booted to LineageOS recovery (Home + Volume UP + Power)
- Factory Reset -> Format data / factory reset
- turned off the phone via menu entry from recovery
- re-inserted my external sdcard
- re-booted to LineageOS recovery (Home + Volume Up + Power)
- 'Apply Update -> Apply from Android', then navigated to the file 'lineage-18.1-20230515-nightly-jfltexx-signed.zip' on the external sdcard and flashed it.
- 'Reboot system now'
Then the phone seems to work fine, but unfortunately the functionality still doesn't work.
Settings such as sounds and notifications naturally seem to have been reset, but closing the lid of the flip case just turns off the screen, it does not display the clock-face.
Maybe I'm missing some very simple setting which should have been set up upon booting the freshly installed OS?
Also, what I don't understand is that Google PlayStore is installed by default, despite the fact that I wiped my phone and did not side-load Google Apps.
So I suspect the above procedure does not completely erase the previous installation, and I hope someone will point me in the right direction with regards to doing this properly.
On a related note,:
- At some point in the past I unsuccessfully tampered with Google Apps entry within '/addon.d/' to fix PlayStore which kept crashing, which made LineageOS unable to boot. Upon applying mindgapps addon from LineageOS recovery, LineageOS booted again, PlayStore was not fixed, though.
- Around that time, I also tampered with '/system/build.prop' to deal with an app which refused to run on non-stock firmware. As I could not make this work, I reverted the built.prop file to its original version, but I'm not entirely sure about this.
I wonder if my messing with the above system files influenced the OS not to be properly wiped.
