Moto G5S XT1792. My stock 8.1 Moto Camera was unstable, mostly after starting the app by double twist, the camera would take the picture but not save it and the camera app would crash. I lost too many pictures because of this behavior.
I finally decided to try this Pixel Experience ROM.
My first attempt I did just a simple wipe of the partition. The result was not good, will not elaborate to keep this post short.
Using bootloader I flashed removewarninglogo.bin to remove the annoying message at every reboot about phone being rooted.
I decided to do it all again. I took out the SD card, (my SD card is set as removable storage) and used TWRP to format everything, except for the SD card. Flashed the Pixel Experience ROM and before the restart, I did a dalvik/cache wipe. I did not restore the Google backup, so every app and settings were installed/configured from scratch. I put the SD card again, set it as removable storage. I noticed that the speaker volume seems lower than before.
For some reason, I did not need to reflash removewarninglogo.bin because the annoying message about phone being rooted is not shown anymore.
Everything else is good, I enjoy the many improvements of 9 Pie over 8.1 Oreo.
But the camera app is ruining my day. I am using default settings, except for the storage folder (selected the sd card). As soon as I open the camera, phone starts to become warm. Sometimes after taking a few pictures, the camera app restarts. If I try to use the "Lens Blur" option, after taking the picture the screen will freeze for several seconds and the app will close. For selfies, the front phone flash will not work, the app will only use a white screen to simulate a "flash". The result is terrible: a black picture with some highlights in green, just trash.
Short movies seem fine but I did not made extensive tests.
My SD card is a 32Gb Sandisk Ultra class 10, Micro SD HC 1. I wonder if I need to reformat it before installing the Pixel Experience ROM and/or I wolud like to hear from you if there is something I can do to make the camera app stable as expected.
