Samsung Galaxy Note 20: Why is my touch not working with my finger but my S-pen works fine?

Sun, 07 Jul 2024 10:20:58 -0700

As of three days, my touch on my note 20 isn't working with my finger but works with my S-pen. It worked one night, woke up the next morning and the touch stopped working. How is this possible? Was it a bad update? Screen going bad? I have warranty but don't wanna wait a couple days without a phone or drive 2 hours away to samsung. Thanks !

Samsung Galaxy Note 20: I dropped my phone and now the bottom 1/8 of the screen is a white bar

Tue, 16 Jan 2024 16:43:32 -0700

As context, I currently have a Spigen case on my phone, so its pretty rigid, having survived wear and tear previously, even worse drops. However today I tripped up and dropped it so that it fell, then bounced into my radiator. This now means that the screen is in one of two states, normal apart for a white bar at the bottom, presumably where the screen hit the radiator; or desaturated colors through the screen, with flickering white streaks. Attached are photos of both of them.

I have booted my phone up in safemode, and the damage is still there, so I can rule out it being a software defect.

There appears to be no noticeable damage on the exterior of the phone apart for a few scratches on both the screen and edges from general use.

Does anyone know specifically whats broken within my phone? I assume its internal and most likely something to do with the connections to the screen. I'd just like to know so that i can decide whether its worth attempting to fix on my own; taking to a store to get fixed or replacing it entirely.

Any and all help is appreciated :)

Samsung Galaxy Note 20: Device is not charging with cable but charges wirelessly

Thu, 30 Nov 2023 13:39:22 -0700

Hello, my note 20 stopped charging via usb cable, I tried to chage it wirelessly and it works. I thought it was a charging port issue so I gave it to a local shop to fix it and they said it's the capacitor.

I'm not an expert but if the capacitor is failing then why is it charging wirelessly?

Mon, 16 Oct 2023 12:06:26 -0700

Hello there! I have fixed many phones with glass back covers, but this Note 20 was my first device with a plastic battery cover. I used my T9000 liquid glue that use for almost all repairs but this time, it desolved the color layer of the back cover? Did I do something wrong here and have you had this issue before? Thanks😉
