Galaxy S23 Ultra: Phone nit charging after battery swap and calibration

Mon, 20 Apr 2026 09:29:43 -0700

Hello yesterday I swapped the battery in my s23 ultra i tested if it would charge while I had it open so I closed it up and let it surcharge up to 100% then after a normal usage day i let it drain till it shut down but now it won't let me charge it anymore i can charge it wireless but it drains extremely fast afterwards charging port seems to be fine too cuz if I try to put my charging cable in while wireless charging it tells me that the device was connected by a charger and that it stopped charging it i used the wireless charger of my s26 ultra

Galaxy S23 Ultra: Just front glass, OEM quality?

Tue, 14 Apr 2026 18:24:17 -0700

I'm hoping to find just the front glass. After years I managed to crack it and it spidered out. Wouldn't mind but it messed up my fingerprint sensor lol. OLED is fine, so I'd love to avoid $320 and just get the glass. I'm experienced with repair and already replaced the battery once. I just don't want to buy just glass and get some fragile garbage - preferably as close to OEM as possible but just the glass. Sadly iFixit doesn't have it and I'm not usually working on phones (I repair usually game consoles and audio equipment, but do other stuff too)

Any ideas on a solid supplier of Gorilla glass s23 Ultra front glass assembly (just glass and adhesives needed for ipx rating)?

Galaxy S23 Ultra: Explanation on why alt OLED displays stop working after updates?

Tue, 03 Feb 2026 11:42:48 -0700

We've had this conundrum with our colleagues at our repair shop since we've opened up to repairing other phones besides iPhones, every time most of the OLED displays we buy for screen replacements stop working after any software update, does it happen to any of you and if so why would it be?
It's been a long time since we've tried updating a phone with an OLED display out of fear of losing the replacement part, so we don't know if this is an issue that has been resolved with the manufacturers.

Galaxy S23 Ultra: S23 ultra not vibrating, and mobile Internet connection is terrible

Tue, 20 Jan 2026 06:44:06 -0700

I dropped my phone on its back from a 3 ft height, it stopped vibrating (well, when I restart the phone, it vibrates weirdly (high pitched) then stops all together) and I've noticed that the mobile Internet is really bad. Like it might be working fine one second and the next, it can't load up a website ( I use the same carrier on my tablet and it works fine, so it's not that)

I don't know if there's something out of place or what to do. I'm very reluctant to take it to a repair shop, I don't want any extra damages, and the Samsung/carlcare center is too far away.

Please help!

I have a Samsung Galaxy S23 Ultra. It was exposed to warm water a couple of days ago. After that, I noticed condensation in the camera lenses. Now the phone overheats and keeps restarting even when it’s unplugged. It’s currently powered off

Galaxy S23 Ultra: S Pen is not recognized in the slot

Mon, 08 Dec 2025 13:09:34 -0700

I’m having a problem with the S Pen. Basically, everything works fine between my S23 Ultra and the S Pen, but not when the pen is inserted into the S23’s slot.

When I place the S Pen on the coil (see picture), the pen is recognized and the smartphone connects to it. If I lift the plastic cover with the coil and slide the pen underneath the plastic, it is also recognized. Only when I place the plastic cover correctly over the slot and insert the pen is it not recognized at all.

The pen is also recognized when I place it only halfway onto the coil.

I’ve also tried working with some distance above the coil (1–3 mm), and the pen is recognized. I placed a 1 mm thick piece of plastic on top of the coil, and the pen is recognized as well. But in the fully assembled state, when the pen is correctly inserted into the slot, it is not recognized.

What’s puzzling is this: When the pen is inserted and I place the phone on the wireless charger, the pen is recognized. When I take the phone off the wireless charger, the pen remains recognized. Only when I pull it out and insert it again does it stop being recognized.

I’ve really tried a lot, but it seems as if something inside the slot is interfering with the communication between the coil and the pen — but only inside the slot. I checked to see if there was anything stuck in the slot, but I can’t find anything.

Does anyone has an idea?

Galaxy S23 Ultra: Is the Samsung S23 Ultra replacement battery 45W?

Thu, 30 Oct 2025 08:31:05 -0700

Hello, on August 6th, I ordered Ifixit's Samsung S23 Ultra Replacement Battery. Is it 45 W ? I am askig because I wasn't able to charge it above 30W (I'm using a 45W charger and a compliant cable) and Ifixit's specification page doesn't indicate this information. It just says that it's an aftermarket product as close as possible to the original and it gives various numbers EXCEPT the wattage.

Thanks for your help.

Galaxy S23 Ultra: I think my charging port is loose or bad or dirty.

Wed, 27 Aug 2025 21:21:39 -0700

My phone frequently disconnects from the charging cable/Android auto I've tried new cables and it still happens. I have to unplug and plug it back in to reconnect, but if the cord moves a little bit, it disconnects again.

So I think it's an issue with my port on the phone.

Galaxy S23 Ultra: Screen not working after battery replacement

Tue, 12 Aug 2025 06:05:21 -0700

I changed the battery because it wouldn't hold a charge...Everything in install went good. I turned it on and Everything powered on, I put it to charge and it's charging good.. So i go to sleep leaving it charged. I wake up and the screen won't power on or anything. But when I do connect a charger it vibrates to indicate it's connected. I try connecting to a laptop but nothing appears but it does vibrate twice when you connect it. I re checked ribbon connections and everything is connected good...Not sure if the screen just went out....Never had a problem with the screen before this.

Galaxy S23 Ultra: Why is my bluetooth keep dropping connection?

Tue, 05 Aug 2025 17:04:06 -0700

I've tried every single method provided by Samsung, but I still can't figure out why Bluetooth drops and reconnects every 30 seconds or so.

The phone was fully reset, and safe mode was tried, but it's still happening.
