Quite a few users on the Samsung forums have reported issues with their Z Flip 3's microphone. When trying to make a call or recording a voice note or video, there is distortion and no voice can be heard, just static.
Samsung has responded with some possible solutions to the problem but has yet to acknowledge whether this is in fact a hardware issue or provide a fix. You can try the below steps to see if this fixes the microphone problem for you:
Step 1: Remove anything plugged into your phone such as adapters, chargers, selfie sticks, etc. Also, remove any third-party cases or screen protectors — basically anything that is in contact with your phone and could be causing interference.
Step 2: Disable Bluetooth by swiping down from the top of your screen to open the Quick Settings panel, then select Bluetooth to turn it off (it should be grayed out when off).
Step 3: Then, restart your phone by holding down the Power button and tapping Power off.
Step 4: Wait for 30 seconds after your phone has shut down, then press the Power button to power on your phone.
Step 5: Once your phone has rebooted, use the Camera app or Voice Recorder app to record a short audio clip.
Step 6: Play back the clip to see if the microphone issue is resolved. If it is, the issue is likely being caused by a connected accessory or an app you recently downloaded.
If the issue is not resolved, the phone's hardware may be faulty, and you should contact Samsung to organize a repair or replacement.
Users on the Samsung Forum have experienced the Z Flip 3 overheating while using Android Auto. It seems this isn’t an isolated incident, either. Other users on the XDA Developers Forum have reported the phone getting very hot to the touch in the area under the cameras when playing graphically-intensive games like Call of Duty: Mobile. And perhaps worryingly, some users have also reported the phone gets unusually hot while doing basic things like making a call or browsing the web. This could be due to the Snapdragon 888 processor, which does get significantly hotter than previous processors, or it could be caused by an app consuming a lot of battery.
One recommended solution is to remove your phone from its case while watching videos or during heavy gaming sessions, particularly on a hot day, as this may help it to keep cool. If your phone's overheating while using Android Auto, you could try closing background apps, and make sure you're not charging the phone wirelessly while using the app. Samsung also recommends you keep your phone out of direct sunlight in the car.
It's also worth trying to clear your phone's cache partition; here's how to do that:
Step 2: Press and hold the Volume Up key and Side key.
Step 3: When the green Android logo appears, release both buttons.
Step 4: Press the Volume Down key a few times to highlight Wipe Cache Partition.
Step 5: Press the Side key to select.
Step 6: Press Volume Down to highlight Yes, then press the Side key to select.
Step 7: Once the wipe cache partition is complete, you'll see Reboot System Now is highlighted.
Step 8: Press the Side key to restart your phone.
You could also download a temperature monitoring app like CPU Monitor to check whether the phone is actually overheating, as it may just be getting a bit hot to the touch. If it appears to be seriously overheating, the next steps would be to contact Samsung for a repair or a replacement handset.
A user on the Samsung Forum in Korea reported issues with changing the brightness in Flex Mode while listening to music. Apparently, when trying to adjust the brightness in Flex Mode, a second column appears for volume, and the brightness does not change, but the volume instead increases. This video shows the issue a bit more clearly.
Samsung released a software update last September to fix the issue. If you're still experiencing problems despite running the latest software version, reach out to Samsung for a repair or replacement handset.
There have been reports on the XDA Forum about battery drain while the Z Flip 3 is in standby mode, with one user reporting a 32% drain over eight hours while they were asleep and others reporting a huge battery drain on the first day of owning the phone. The causes for this may vary — for example, a new phone takes time to learn your habits and optimize battery life, so it’s a good idea to monitor drain over the first week. If it’s still an issue, there are a number of things you can try.
First, check out Settings > Battery and device care > Battery. This will help you see what’s draining the battery and identify if a specific app is at fault. You could also try disabling Always On Display or check to see what features and processes are running when the screen is off by going to Settings > Advanced features > Motions and gestures. Or try disabling features you don’t need, like Edge panels and Edge lighting. Another thing that’s worth trying is optimizing battery usage. Here’s how to do that:
Step 2: Select the three vertical dots icon at the top-right of the screen, then select Special access.
Step 3: Select Optimize battery usage, then choose the drop-down arrow and select All.
Step 4: You can then toggle the slider for each app you want to optimize.
Other things you could try are putting unused apps to sleep, turning on power-saving mode, uninstalling or disabling bloat you don’t use, or even disabling the Cover Screen when notifications arrive if this isn’t a feature you’ll use.
Issues with Samsung Pay not working on Samsung phones seems to have been around for some time now, and it looks like it continues to be an issue with the Z Flip 3 and the Z Fold 3. This seems to mostly be affecting users in the U.K. and other parts of Europe, with some mentions that the Samsung Pay app opens with a page in German — obviously not ideal if you don’t speak German!
The issue is actually caused by a mixup in the CSC code when the phone is set up, leading to Samsung Pay to operate in German, which isn’t good news for those residing in the U.K.
Until Samsung has a permanent fix for this, there are a few things moderators over on the forums have suggested trying — though some users have reported these fixes don’t work.
Step 2: Then go to Settings to check for Software Updates and/or Samsung Pay updates.
Step 3: Once these are installed, turn off your phone’s Wi-Fi, then turn it on again
Step 4: Then, uninstall Samsung Pay by long-pressing the app icon and selecting uninstall.
Hopefully, Samsung will soon address this problem via an update, but for now, all you can really do is give the above tips a go to see if that resolves the issue.
This is a known issue that has affected Samsung phones on T-Mobile in the past. When sending an MMS — or group text, since group texts use MMS — users are reporting the line
We recommend reporting this issue to your carrier and to Samsung. Hopefully, a fix will be found in the near future. In the meantime, you could try using Google Messages as your messaging app or try installing a different messaging app from the Play Store, like Textra, which doesn’t have the subject line issue.
Several users over on the Samsung forums and Reddit have reported issues with their Galaxy Z Flip 3 screen cracking. This usually happens along the fold, and even happened to a writer over at 9to5 Google, who reported it happening after a few days of not using the phone. Although it doesn't appear to affect functionality, nobody wants to use a phone with a cracked screen, so what can you do?
Check if your Z Flip 3 is still covered by the one-year warranty. If it's outside the warranty period, you'll need to contact Samsung or go to your nearest Samsung Authorized Service Center for a screen repair. If you're lucky enough to have a Samsung Care+ subscription, you can have your screen repaired at a lower cost.
Reports of the Z Flip 3's main screen malfunctioning when opening and closing the phone suggest that this is a pretty irritating problem with no known fix. When this happens while opening the phone, the screen won't turn on until you close the phone and reopen it, or wait a while.
While there's no known fix for this right now — and Samsung doesn't appear to know what's causing it — there are some things you can try to resolve the issue.
Try restarting your phone in safe mode. You should also ensure you have the latest software update, as some users have reported the issue resolved after updating their phone.
It's also worth sending an error report to Samsung so that it can investigate what's causing the issue. Here's how to do that:
Step 1: Open the Samsung Members app and select Get help at the bottom of the screen.
Step 2: Scroll down to Send feedback and select Error reports. Then select your error type, in this case, Display.
Step 3: On the following screen, select the Frequency from the drop-down menu, for example, Once, Often, or Sometimes. Then fill out the error report with details of the screen malfunctioning error and ensure Send System Log Data is ticked at the bottom of the screen.
Step 4: Then, when you've finished filling out your report, you can attach screenshots if required by choosing the paperclip icon at the top right. Or you can select the Send button at the top right to send your report.
Are you tired of paying for streaming services you never watch just to get a phone plan feature you actually want? T-Mobile has good news for you! The carrier is rolling out new plans, called T-Mix, in early November to replace its old Experience lineup with a build-your-own perks system called Picks.
The benefits you choose vary from streaming and gaming to food delivery, AI, satellite service, and phone discounts. But if you are satisfied with your existing plan, you can keep it.
Merely days after the iPhone Duo hit the shelves, images of broken screens on the phone started popping up across social media. Until now, it’s been unclear what’s causing the line of defective pixels that appears vertically along the crease, as well as horizontally, on the phone’s inner display.
Apple has finally acknowledged the issue, which has shown up on iPhone Duo units owned by customers as well as demo units in stores. In a statement shared with Bloomberg, Apple says that not all iPhone Duo units are affected and that those that are tend to show the display fault early on. The company added that users who experience problems with their iPhone Duo display should contact AppleCare for a replacement.
Not long ago, Apple treated independent repair like an act of outright hostility. The Cupertino giant locked down parts with serial-number pairing, while repair tools remained firmly out of reach of anyone outside its authorized repair network. More importantly, the company waged a legal and lobbying battle against right-to-repair legislation.
I've covered enough of these fights over the years to know what a shift looks like. That's why what happened in October 2026 genuinely caught me off guard. The day the iPhone Duo went on sale, what may be the most mechanically complex iPhone to date, Apple pulled off a surprising about-face. It published teardown-style repair manuals for a handful of major components.
