Just purchased an A53 5G and disappointed in the preinstalled stuff that nearly made me take the phone back but with perseverance and searching endlessly online I have solved most of them. This shouldn't be necessary.
The phone was taking screenshots endlessly and my gallery was full of them. One 2 hour walk resulted in 39 screenshots. Now disabled.
Switched off Palm Swipe too as this seemed to be activating itself.
Uninstalled all the software that was possible to do that I didn't want.
Email only showed mail from the last few days. I wondered where it had all gone but then found out I needed to search online for an answer to this too. Needs syncing "All Time". Another silly thing to have to do.
Turned off "Analyse on-screen text" as this is unnecessary.
Had to put on "Accidental Touch Protection"
Gallery is messy, shows photos randomly instead of those last entered, now have to press the three lines to view recent.
Gallery has limited facilities compared with that on my previous Huawei P20 lite which was excellent. Biggest nuisance is no sharpening tool.
The biggest let-down is the camera. Wow for a 64MP camera it's shocking, how come? Zoom in and it looks like something from outer space, can hardly make things out. Again, comparing it with my P20 lite which was excellent.
On the whole I love the product but feel some of the items mentioned above need addressing. Probably most important would be to provide a leaflet in the box with all the features that are enabled/disabled to save having to look through every single setting in the phone before being surprised by what is happening.
