Chosen Solution
Hi there, Firstly, the phone we have was not listed. My son has a samsung A40 (UK) after only having it for a few months the phone stopped charging. We bought a new cable and checked socket etc but still nothing. We contacted the provider who told us to take it to car phone warehouse. They said that it was a faulty charging port and that it wasn’t covered under warranty. They also said that they will wipe the phone should we chose to have them repair it, as this was their standard procedure. My son had not been able to back his phone up as it had died at this point and didnt want them to wipe it. So, as I have repaired a fair few phones in the past, I bought the part (a small circuit board pba) and easily swapped them over, however, the phone was still not charging. I even bought a second one just in case the part was faulty, but it still won’t charge. I cannot perform any software troubleshooting as the phone is dead. Any help would be greatly appreciated. Kindest regards Claire xx
Hi, Same here, I’ve tried every possible workaround on the web. In my case it is certainly a physical issue. Due to the poor construction of this phone, it seems that the back case which is very very very thin and cheap is causing the MAIN connector cable to move from its socket. This basically disconnects the SUB board from MAIN board, causing the issue.
I’ve opened up the phone and tried various methods to fix this. There is no bulletproof solution as the back-plate which is supposed to keep it in place is very very cheap constructed and bends like butter. In my case, pressing relatively hard behind the phone (just below the Fingerprint sensor (On Spot on the SAMSUNG logo) makes the phone charge randomly. That is the place where the plug of MAIN connector cable is located. I hope this helps, I don’t know if I will ever invest in a samsung phone ever again. This is the second one randomly dropping down on me, funny stuff after an S9 display simply failed. I had to mention that my iPhone 5s is still fully functional with an almost dead battery after almost 7 years Best of luck,
Hi, I have a Samsung A40. After some months it wouldn’t charge via its Brick (2A Samsung Brick/transformer). It would only charge by USB on my PC. Later i found it would also charge from an Alcatel 2A Brick and an Alcatel 1A Brick. It soes not charge using my XIAOMI 3A brick. Using the AccuBattery app, it seems that the Alcatel 2A Brick produces 1.7A. I tested the 2A Samsung Brick on my XIAOMI and it produces 2.1A. It seems that the Samsung A40 will charge if i use a power source that produces less than 2A.
Hope that this helps.

Hey i have this problem too every now and then. And i tried everything like software updates and bying new cable, but ofc nothing of that worked. But i later dropped it (from 30cm height ca) by accident and after that it charges again. So i have fix the problem with both my brothers and my phone, by gently hitting (not destroy it) 3-5 on the back where the charging port/battery is located, cause it seems to be a cable in there that has loose contact or something. Idk of it helps you guys, but it might be an option :)
