Samsung Galaxy Z Fold3: Samsung Fold 4 Frame Damaged and Will Not Fully Open

Fri, 02 May 2025 13:25:06 -0700

The phone was dropped and landed on the bottom corner where the hinge is located. The affected area's side will not fully open and feels stuck when attempted. I can only half open the fold.

I viewed teardown videos but I am not confident that opening the front LCD will reveal the affected area and that I can fix it.

Does anyone have tips or might have an answer on how to fix this?

Samsung Galaxy Z Fold3: Why will Wi-fi not function on phone

Tue, 29 Oct 2024 08:03:29 -0700

Problem: Wi-fi toggle switch will toggle for a few seconds to minutes but not connect and turn back off. No new updates or apps. Bluetooth works, data works.

Attempted Fixes: Restart, cleared partition, reset network settings, factory reset, Removed smart things. What else is there to do and how?

Samsung Galaxy Z Fold3: No sound working on the device

Sat, 20 Dec 2025 07:58:32 -0700

My phone does not have sound, doesn't matter if its folder or not. My camera said recording failed when i switch to video. When I call someone, the speaker button is stuck on. Also if i call someone, if they answer the phone call, it drops. While to phone is on, to the right of the rear camera, it starts heating up immediately. Tried resetting and safe mode but didn't help.

Samsung Galaxy Z Fold3: Can I switch foldable screen for ordinary flat?

Thu, 30 Nov 2023 07:37:33 -0700

Is there a way to replace foldable screen with ordinary OLED display? I have this question because if it is possible many "dead" phones with broken front panel could be revived as makeshift powerful tablets and reduce waste.

What do you think about this idea, is it feasible?

Samsung Galaxy Z Fold3: The 2 Screens not always working

Tue, 25 Apr 2023 08:04:16 -0700

I dropped my phone

The front screen didn't work, but the inside screen worked. I used the tap and massage the phone technique. The outside sceen now works, but the inside screen doesn't work. If I partially open it, I can get the screen to work intermittently. But once it's about halfway open the screen doesn't respond. I opened the phone to see if reconnecting the ribbon cables would work, or if I could find anything loose. I tried clearing the cache in safe mode. I've tried taping and massaging it more, no difference.

Is there a board or cable that I can replace, that might be a likely culprit? Is there a diagnostic software I could use to find the faulty part? Or any other ideas?

Thanks Dan Mayer

If I purchase a new fold3 main screen, have the replacement screens been improved to be more resilient (like the Fold4 supposedly have)? Or will this next one fail in 3 months, too?

Samsung Galaxy Z Fold3: My phone wont unfold flat.

Fri, 02 May 2025 13:46:27 -0700

One day out of the blue I go to unfold my phone to use it (as I normally do) and it won't unfold all the way. It has about a 10 degree fold to it and won't lay flat. I've put a little bit of pressure on it but I'm afraid to do more for fear that it will break.

Samsung Galaxy Z Fold3: Vibration motor intermittent flex or motor fault?

Thu, 05 Dec 2024 06:43:39 -0700

I have a z fold 3 hasnt been dropped still has majority of the factory stickers still on No sooner did warranty end the motor decided to play up

Whilst typing sometimes the haptics totally stop working sometimes I have to close the fold which gives me a buzzing vibration feedback much louder than what the usual vibration sounds like and it'll start working again at times I have to tap the back of the phone where the motor typically sits and that gets it to work again

Is this possibly a motor issue or the main flex
