I'm having trouble starting my A40. When the charger cable is plugged in the percentage charge is clearly displayed (100%).
Before the start problem there was a time lag between pressing the side bar and the phone display lighting up.
Memory was low .
I had an informal chat with my local repair shop and they mentioned a new mother board, something I'd like to avoid if at all possible due to losing all my app data ,stored passwords etc!
Any help would be fine. I've tried the various start combinations.#
My apologies if you've tried the following methods.
I appreciate what your local repair shop thinks the phone may need but I would strongly recommend going to a Samsung Experience Store or Samsung Service Centre for support.
It may not be as drastic as replacing the internal board.
It might be software related.
I wish you all the best with this.
