Samsung A40 (UK) won't charge

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, I would be interested to hear how you’ve got on with this please as we are having exactly the same issue with the same phone that is only 9 months old. No damage done to the charging port but I have ordered a replacement to try to fix it myself.

Thanks in advance

Hi there, I'm sorry, I can't really offer any advice. I've changed the part twice (just in case the first was faulty) but it's still dead as a dodo! We have been trying to sort it with the provider but due to their shop's being closed due to Covid-19, we haven't been able to sort it. Sorry I couldn't be of any help, please let me know if you make more progress than me. Kindest regards Claire xx

Hi, I have exactly the same problem, my A40 just won't charge. I cannot find any information on the software fix, my phone still has battery so I would like to try that , anyone can help ?

Thanks

von

Whilst your phone still has battery, does it have the most up to date software? To check go to settings, software update I think and it should tell you in there the last date it was updated. If not a recent date, try clicking on install and update.

Had the same problem - my first A40 stopped charging after 2 months and after sending it back to John Lewis under warranty they replaced the charging port, factory reset and returned the phone. My first charge worked and then after reinstalling my apps it wouldn't charge leading me to believe it was a software issue.

I got a replacement phone which worked fine until I reinstalled the Garmin app which I thought was maybe the problem. Removed that and still get periodic problems with charging - tonight being an example! Pretty sure it's a software problem rather than a faulty charging port, etc.

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,

Thank you so much! You are amazing and you just fixed my problem on my phone. Even as a 12 year-old tech savvy kid I couldn't find the problem.

I dont understand the other comments but @psecto 's suggestion to solve the A40 charging problem is worth gold. I dropped my phone and then it stopped charging hough there is no visible damage. I pushed on the backside right on the Samsung logo a couple of times - quite hard, indeed you feel the backcover denting - and it started charging! Thx! Harro

Well today we're opening the phone - or trying to.

My girlfriends A40 also stopped charging today, after we took a hike in the rain, so initially, I though that moisture ingress might have been the culprit. After pressing down on the Samsung logo on the back, it's charging again! Thanks so much for your suggestion!

von

Thanks so much! This happened to me when I fell off my bike, onto my phone. It seemed undamaged, but last night when I hooked it up it wouldn't charge.

This instantly fixed my problem, you saved me the trip to the shop, and them probably wiping my data.

Hi!

So, you already replaced the charge port, right? Did you tried with another battery? It could be the battery which is faulty and not holding any charge.

Hi koppie,

Yes, I have replaced the port twice. I haven't tried a different battery but I'm doubtful that it's to blame, given that I have researched this and there are many people saying that this is a common fault and repairable with a software fix, only I can't do this due it being completely dead! This phone is less that a year old and under warranty!

Kindest regards

Xx

Hi!

Did you recently updated the phone ? It's weird anyway, as it should boot at least to the OS to activate the bug in the software. Sometimes when you put a new battery in, there is still charge left so you can immediately back-up the phone at that moment (if it's still not charging) and then check and run updates once more to fix it if it's software related. There is not much more you can do at this point I'm affraid... Only to bring it in for warranty (if still possible after the earlier repair?) or to ask a local repair shop to do what I explained (guess they will not charge for a complete battery if not needed).

I have had this issue too. My A40 phone is 9 months old. After a very arduous 1 hour support online chat with Samsung, they arranged a contact- free collection by courier of my phone to take away and fix under warranty. I was told if it was found to be something I had done rather than the phone I would have to pay the repair bill. Given I know that nothing had happened to my phone, I sent it off. Went Tuesday and is due back tomorrow. Not sure what was wrong with it, if it is fixed or it is a new device as I have had zero contact from Samsung other than to say my phone is being returned . Crucially, I haven't been asked for any money either.

We bought the phone through Currys but their online advice during covid was go to the manufacturer as it is under warranty. I did that, so we will see if it is fixed. There is a clearly a pattern emerging with this phone. If it isn't fixed then I will see if we can claim on the credit card we purchased it on or will go back to currys and ask them to replace it ( and sit in their call queue for over an hour).

This is exactly what I have done with my phone although we did buy directly from Samsung. The phone was returned last week and now works and charges absolutely fine. No communication as to what was wrong or what they did to fix it though!

Hey thanks to the folk above with the tip on pressing on the samsung logo, I've had my A40 in for repair twice in the last week and was about to send it back to virgin mobile whom would no doubt refuse to comply because I've used an unauthorized dealer to attempt fix.

So far since trying my phone's now nearing a full battery

Hi there, my fix for the Galaxy A40 issue of NOT charging due to poor construction. So we know the issue is right here with the main flex

IGNORE THIS SOLUTON AS IT FAILED

THE RIGHT SOLUTION AT THE END OF THIS POST.

Block Image

I took adavntage of the flexible plastic backcover and I used little more than a half of a toothpick piece and placed it right on top of the problem

Block Image

Because of the cheap plastic back cover it adds just enough amount of pressure on the faulty flex by construction without braking anything.

Block Image

Block Image

close the phone back and it charges again

Block Image

at the cost of a toothpick.

I hope this helps, let me know if it worked out for you. Thanks and have a great day

UPDATE: it worked for a few hours so to speak, so ignore my solution, meanwhile i have found the solution to last also involving a piece of plastic that i have placed under the main logicboard precisely under the connector, now it works truly so far so good, cheers
