Hi,
First thing first, I am aware the device is old by now, so I know what to expect from it.
I don't remember exactly when the problem started, but at least I have endured it for the past two years.
When I purchased the device, it was running Android 7. After a period, there was a slight slow down but I thought it's because I had too many apps installed.
But then, when the update gave me Android 8, things were suddenly speeding up again, buttery smooth. Right after the reboot, menu sliding were very responsive, launching camera, taking screenshots, etc. Alas, I didn't have the chance to launch any app to test it, since the speed-up lasted only for one minute or so.
The same thing happened again with the Android 9 update.
At this point, I'm certain Samsung is throttling the device. Wiping the cache partition and factory reset didn't resolve the problem.
Does anyone else had the same problem, and perhaps even share the solution?
Thanks.
