Samsung Galaxy Note 20 Ultra 5G: How to clean the usb-c port on my mobile phone?

Fri, 01 May 2026 10:06:33 -0700

I have problems with the usb.c port of my mobile phone (note 20 ultra 5g), most likely dust. I have seen that one could use a spri on a wooden toothpick (like Stickum), but my doubt is: after using it inside the usb-c port, it will be sticky and then it will be worse. Alternatively, can you list other Stickum-type products that do the same thing but do not damage the mobile phone? Lária compressed I think worse would be a mini but strong hoover as an alternative Other ideas?

Samsung Galaxy Note 20 Ultra 5G: Modification Galaxy Note 20 Ultra Motherboard did not go as planned.

Sat, 27 Sep 2025 05:43:32 -0700

I had 2 Galaxy Note 20 Ultra Motherboard that is in Normal Condition. One is the Hong Kong Version and the other one is the Japanese Version.

I bringed both motherboard to a repair shop to do a Sandwich Board Seperation, because I want to swap the top sandwich board to modify the Hong Kong version of the motherboard to have the 5GmmWave Antenna.

After the Sandwich Board Seperation is finished, the Hong Kong Version of the motherboard is able to power on but it restarts every minute. The other motherboard the Japanese Version is able to power on normally, but it shows an Unknown IMEI and Baseband do the repair shop decided to redo the Sandwich Board Seperation.

After few times redo the Sandwich Board Seperation, both motherboards are completely died. Can you tell me what caused the motherboard to completely died?

Samsung Galaxy Note 20 Ultra 5G: I just replaced the screen, and image and touch problems

Sun, 17 Aug 2025 16:11:02 -0700

Just replaced the screen, back glass, frame, and battery.

I've run the diagnostics, and that runs fine. But when I'm operating the phone normally, swiping up (i hate the real estate taken up by the button options for home, back, etc).

It also seems like I received a display for a smaller phone put under the note 20 ultra glass (the corners are cut off, but screenshots show the processer is putting out the full image).

I am unable to update the TSP Firmware (via *#2663# [says FW update failed).

My fingers don't register when I try to swipe down the notifications/settings menu, it might be an issue of my fat fingers, but i didn't have this issue before the screen swap.

When I touch the screen to make a phone call, it shortdown the number quickly so that I cannot push on the phone icon in order to make a call. This malfunction last for about 10 minutes or thereabouts and then it resumes normal functions again. When this happens, the camera button will not work and the videos on the phone freezes or goes into a slow motion with intermittent pause.

Samsung Galaxy Note 20 Ultra 5G: NFC no longer working post Battery replacement

Fri, 08 Nov 2024 10:39:04 -0700

Initially, my phone got hot to the point I realised the back cover naturally just came off and my phone was discharging quicker than usual.

Found the battery was swollen a bit as squeezing the back cover back on was not possible.

Ordered battery replacement for 4500mAh and found NFC no longer working and the phone discharging a lot faster than usual (ie I'd leave my phone at 30-35% at midnight and wake up at 7am with 1%.

Thought it was battery issue, ordered a high capacity battery 5000mAh and replaced the battery, lasting slightly longer but still a fast discharge rate and NFC still not working.

Appreciate any help with resolving both battery dissipation issues and NFC no longer working.
