Thanks. I was able to fix my partner's z flip 4. Her phone was shutting down whenever the phone was flipped. I thought something was loose inside so I watched your video and tried to disconnect and reconnect everthing. After that, phone is working just fine. Thanks, bro!

Great effort, but would have been better if you kept on tearing down. I'm mostly interested in the new hinge design and updates to the display.

Maybe down the road you could show how the hinge assy is installed since lately many users are reporting failures without any type of over use or abuse. with the hinge failure the phone is pretty much unfoldable. Great video should come in real handy for all the bad Flip 4 phones.

Good video. My other halfs phone has just packed up. It works fine when open but after its closed, it refuses to come back on. If you tap it, eventually, it comes back on. Sent off under warranty and they refused to repair it, saying it had been damaged. It literally hasn't got a scratch on it. Always kept in a case, never dropped. Samsung want £425 to repair. My response this product isn't fit for purpose.

Question.... would you know why my z flip 4 disconnects from battery when i close it? It's either getting a short somewhere or the hinge is pulling the battery cable somehow? It only works when it's open. The second i close the phone it turns off and i cannot turn it back on until i open it up again.

Amazing video ! You are by far the Master of teardowns ! I have a couple of questions for you. How much heat was applied and for how long in order to remove the back covers and what do you recommend for the heating ? Hot air gun or rework station heat gun ? Also, can you point to where the test points are located for model F721W ? Thank you !

Super thanks bro! Very educational indeed

This was very informative. I can see how both battery capacities add up to 3700 mah. I'm waiting for this phone to ship. Thanks for the info on its internals.

Used this video to repair my phone. I found one with a bad esn on ebay and used it to exchange the screen. I just took the motherboard from my phone and put it in the ebay phone. Worked flawlessly and was easier than trying to get the screen off the frame.

Thank you for these step by step instructions. You should give lessons to everyone on how do create viewer-friendly DIY videos!

Hello, thank you for this amazing video. By the way, Im having a network/sim problem, I tried all the troubleshooting steps and nothing work, so I think the problem is the hardware? Do you know which part do I need to order? Is it the PCB?, Wave antenna? Qualcom x65 modem? Please help. Thanks

Thank you sir much appreciated for a professional level explanation 👍 ❤

Watching from my flip 4 and I love it. But in paranoid about the screen breaking like the flip 3 so many complaints and pictures and reviews of the crack on fold

[Sarakh]

Hi I need to change the bottom battery but have 5 screws that won't come undone. How could I go about getting them out? Thanks

[tims]

Always love your disassemble videos sir. Any chance you would consider doing a video on removing or replacing the screen on any Samsung Foldable device?

[insenjojo]

What do you reckon? does the overall engineering and build look durable for a 2 year span?

[jerickohjiroyun]

what is the reason why when some of the flip phones are blinking when flex mode? is that related to screen or other hinger related problem?

[Highlanders]

I have a question... If the pcb board charger are faulty, do affect the signal network?

[roudolphoforisomuah]

I went to know if the flip is not opening how would I do it

[ossi.dackel]

Thanks for this great video, can you tell us where to get parts for it?
