I believe you are correct Sir, this is not a hardware problem (well at least for 99% of the posters here...), but a Samsung problem - one which they, Samsung seem to be ignoring. I spent almost 6-8 weeks+ on and off trying to fix this problem. What a waste of my life.
- It has cost me money and will continue to do so for many months.
- I have lost my warranty trying to fix the issue myself, one which Samsung should have fixed in the first place. - I have had Samsung's 'Out of Warranty' services visit my home and had the Engineer simply turned around and walked away, simply because I updated the software manually using Odin (Samsung's firmware updater)! - There appear to be many potential many solutions, some temporary, some permanent. - There is no one specific fix it seems. - There may be no fix at all for your issue.
- There's a chance it could be a hardware issue, either a manufacturing defect or one caused by the user.
- I eventually had to get another phone and contract (having 3 in total!).
My frustration led me down a dark road but, I have overcome the issue by rooting and installing an alternative operating system (LineageOS - see https://forum.xda-developers.com/galaxy-a70 forum threads for the A70 details if you're interested).
This allowed me to install alternative Official Samsung Firmware, and I'm now using the following for some time and have done my best to try and break it (from speaking in the rain, using a car charger bought from the dollar/pound store, to using a cheap USB C charging cable) and the problem has not come back using the following firmware from Samsung: AP_A705FNXXU3ASI2 BL_A705FNXXU3ASI2 CP_A705FNXXU3ASH1 CSC_OMC_OTF_A705FNOTF3ASI2
My regards to Samsung as a 'quality brand' and long-time user for many, many years, has gone from loyal, devoted and trusting, to utter disdain.

@Amarsingh - glad to hear it worked and I hope it keeps on working. Either way, to have to go through what you did, it's just not right - Samsung should get their head out of their a***s and fix their software and NOT have to make us wait hours to download software or even worse, pay for f****** faster download speeds. F*** them.

If you do get it changed, whatever you do, don't upgrade the firmware at all. I had to buy another phone because Samsung said it was out of warranty - I've had it for several weeks with no issues, installed all the software I would normally use and have even used a 'non-Samsung' USB C cable to charge it - no problems.

I did the same, my friend - my phone had a gel case and glass screen protector from day one. I treated it like a f****** baby. I still cleaned it with an anti-static brush and isopropyl alcohol and dried it. I then used a watchmaker magnifier to view the port and there is absolutely no sign of any liquid or water damage (I know, I used to repair mobile phones 20+ years ago). Sad times. :(

I feel your pain my friend. I read on another thread that Samsung said it was water damaged because he was using the phone in the rain. What?!?!?!
Samsung repair (out of warranty service) refused to even look at my phone because I had upgraded the software and rooted my phone. They wouldn't even let me pay for the repair (a software repair too!).
I had to get another phone and contract - I now have 3 contracts and an A70 as a doorstop. FML and F*** Samsung too.

I've tried everything within my capability. I eventually went down the road of:
- Rooted my phone and installing a customer ROM, which worked. I did not like the ROM and reverted back to stock firmware, but now the warranty is invalidated.
- I made an appointment with Samsung repair, who came out knowing full well that I was prepared to pay for the repair, but they refused and said because the software had tampered with - a new phone motherboard is required, which costs 88.99% of a new phone. The call-out engineer said if I had dropped it in the toilet and then called him, he could have done something about it, but I was too honest, he wouldn't even accept my offer/bribe of pizza to fix it.
- Going back to stock firmware brought the problem back.
- Updating to the latest firmware worked, but it's a tease, all of it. - IT WILL BREAK AGAIN.
- Took my phone back, Samsung told me 'buy a new phone' you rooted it, bye-bye.
- I bought a new phone, I have had it a few weeks now and will NEVER upgrade the firmware, everything works and I have a spare to use as a door stop.,
- Lessons learned.
-- Don't root your phone.
-- If you have issues, throw it in the toilet and then get Samsung to repair it and 'bring it back into warranty' (THEIR WORDS!).7
I almost love Samsung, the wiley ****s, I just wish I didn't own any of their products now having been through their super-duper ****y customer service these last few weeks.
I hope you get a dry one shoved in your pie hole Samsung, your mobile phones, your slow download site for firmware updates, and the audacity to charge users if they want to download your cripple-ware-firmware.... faster? Shove it up your prolapsed *********..
Click click, deleted....banned...cheerio people, it was good whilst it lasted.
Warmest of regards Samsung you ****s.

Sounds like you ran into some good luck there my friend! I'm having a similar issue here, well, a frustrating mare is what it is, caused by actions without a doubt and I put my hand up, inf fact, I'm standing in line at the pharmacy to get as much Anusol cream as I can, I need it. I have a 4-month-old A70, here in the UK, it did an OTA update the USB kept going on/off/on/off/charging/keeping the screen on and draining the battery. There are few temporary workarounds but it was getting on wick (UK slang for Moobs etc), sitting on the couch across the room with it flashing on and off like a confused, lost little girl/boy/train Anyway, I rooted mine, and the moment I did that, I could no longer connect to any mobile cell/voice network. Removed TWRP root, flashed stock, no errors, just like new, except for the small tiny part of not being able to makes calls I took it to O2, they returned it with a letter saying, 'unauthorized rework' - buy a new phone if you want to stay with O2. W"haaaaaaaaat?!??!! I've already got two contracts, pay monthly ones too. It's ab-so-lute-ly mental. So I contacted samsungrepair.com, they are authorised by Samsung to repair their shh--ttt..er.er.erbert-stuff. Guy called an hour before he was due to arrive, said 'No Serice? I don't normally do that, only broken screens, charger ports, speakers etc.) But said he'd have a look. I told him the story and like someone else posted, I too was fully expecting to pay, was happy to pay, and wanted to pay! I need a phone. Then guy left, couldn't wait to leave. I get it, we messed with their software and bootloader, but (and I asked they guy) - are you saying I can get drunk, drop my phone is the toilet, phone you and say 'loops, bit of water may have touched my phone, can you please come and fix it?'' They guy said yes! Then, then it'd be "brought back to warranty status" - I've never heard these terms before, bring your screwed up phone you peed all over back to life AND WARRANTY! Anyway, anyone got any thoughts on how I can proceed? - Can I get Knox back to 0x0 (I know I know, just asking? - I've already taken it to the store I bought it from, they sent it away under warranty, had zero communications from O2 Repairs at all, just 'You're phone is 'plucked', you need a new one. - Father Christmas, I've it only had it 4 months, plus I'm still paying the other monthly contract phone (sim only now). The O2 space-cadets called me this morning asking if I'm happy with their tariff’s etc. (LOL poor woman had no knowledge of the situation.). After all, is said and done, yes, it *****ty when you defecate on your mobile and they'll charge a small fee to 'bring it back to warranty'. Plug it into a computer and root, Samsung is just driving a point home, it's just being driven into an awkward body cavity . Yes, I get it that there are other factors at play. with Service Providers and carriers all over the world. But yes, anyone with an idea that brings even tiniest glimpse of hope back (even as small as a fly with a nipple stand on a cold night lol), would be awesome people Thank you so much for reading and kudos to @Chuy for persisting and updating. --------------------------------------------------------------- Finally, I knew the risks, took them and now Mr Shafty is having a go at me. It's my fault, I just wish SS weren't such ---------------------------------------------------------------

See my last post on page 7. THE FIX - FOR ME AT LEAST: - Open the dialler and type *#0808# (it's normally *#2873# on other Samsung mobiles but it did not open the USBSettings app on my phone at all). - As soon as you press the last '#', the USBSettings menu will appear with several bullet-point style options: MTP PTP RNDIS+DM+MODEM RMNET+DM+MODEM RMNET+DM+MODEM+ADPL I selected the last option, pressed 'Apply', exited, confirmed the setting stayed the same, pressed 'Apply' again and then pressed the 'REBOOT' button. It's been a number of days now and it's been rock-solid for me!

Hello, finally have mine working. It looks as though there may be several potential causes to this annoying problem. I tried the following: - Cleared cache/data - Didn't work. - Factory reset - Didn't work. - Tried fudging the notifications by turning off all the notifications I could find (Apps > (Showing system apps) > USB Settings). - Partial fix, no pop-ups etc but the phone will sometimes randomly switch the screen on and its downhill from there. I have a new A70, only 6 weeks or so and, have a gel casing and gorilla glass (installed from day one). I treat this phone like a new-born baby and guarantee I've not dropped this in any water or sat in a steamer at the gym, ahhhhh. I only noticed this since a recent update (maybe 2 weeks or so ago? I'm in the UK with O2). I checked the charging connector with a watch makers lens/magnifier under excellent lighting and could not see any corrosion whatsoever but, I still gently cleaned the contacts with an ear bud (most of the cotton removed and cut in half with a blade to thin it out - used a little isopropyl alcohol and quickly dried with a hair dryer on a low setting. Still did not work! THE FIX - FOR ME AT LEAST: - Open the dialler and type *#0808# (it's normally *#2873# on other Samsung mobiles but it did not open the USBSettings app at all). - As soon as you press the last '#', the USBSettings menu will appear with several bullet-point style options: MTP PTP RNDIS+DM+MODEM RMNET+DM+MODEM RMNET+DM+MODEM+ADPL - I selected the last option, pressed 'Apply', exited, confirmed the setting stayed the same, pressed 'Apply' again and then pressed the 'REBOOT' button. It's been several days now, and the phone has been rock-solid and stable. I can imagine that moisture on the USB C port can cause this type of problem, along with physical damage due to mishandling - I have no doubt Samsung would have cherry picked either one. The Engineers more than likely simply change the charger module (PCB/Flex) as step number one as this is probably the fastest solution. Performing software calibration/diagnostics/updates after that might be done as well but, I guess we'll never know. You might get lucky and have it repaired under warranty, but I can't be without a phone for 3 weeks and get plunged back into the dark ages whilst I wait for the repair diagnosis and must pay for it as well (potentially). I read a thread on this forum, might even be this post, not sure but, the OP stated the Cause' was 'Talking on the phone in the rain' - I guess that could cause issues with your phone, but here in the UK, the rain is very light most of the time, the charging port faces downward too. Most of us use covers or casings too. I really like the A70, it's a fantastic piece of kit, but man, I sometimes wish I just had my old Nokia 3110, 2110 or Ericsson 337! GOOD LUCK and post if you have success so others can benefit too!
