Problem #1: How to fix Galaxy Note8 Bluetooth issue: calls drop randomly when Samsung watch is connected
Hello, I have the Samsung Note 8. It works well with Bluetooth on my 6 year old Mercedes. I bought the Samsung new 46mm watch, released this month. when using the car with the watch on, when placing a call, the call works for 20 seconds, then cuts out for a period of time, then comes back for some time. So the call is intermittent. If I turn the watch off during the call, the car blue tooth works perfectly again. the watch is only paired to the phone, Obviously the phone is paired to the watch and car. thanks for reading this.
Solution: Bluetooth troubleshooting on any end user’s end is very limited. In your case, the only thing that you can do includes the following:
Posts you might like
- unpairing and re-pairing
- installation of available updates for all gadgets involved
- factory reset
If you haven’t tried deleting Bluetooth pairings in all three devices, we suggest that you do that as the first troubleshooting step. As long as there’s no incompatibility issue involved, there’s a chance that everything will work as expected for the gadgets.
In some instances, Bluetooth issues are fixed by installing updates. Smartphones receive more updates frequently than in-vehicle Bluetooth systems. Nevertheless, you should try to do it, especially for your in-car Bluetooth. If there’s no available update at all, then that’s the time to attempt a factory reset. Refer to in-vehicle Bluetooth manual on how to do it.
For your Galaxy Note8, these are the steps below on how to factory reset it.
Problem #2: How to fix a Galaxy Note8 that randomly freezes and turns off on its own
My phone will suddenly freeze on a screen and then i have to force a reboot, but when i do this my phone will not turn back on. This has been happening on and off for a while as when i leave it overnight in the morning it normally will work but then after midday it will then crash and i wont be able to access my phone for ages. it’s a Samsung Note8.
I am not sure why this is happening and have tried force rebooting many times and it will not do anything, sometimes a light will come on the led part at the top but that is all.
If you cant help i will have to go to a store to see what is wrong, i also got this from Three on a 2 year contract and have had it for about June/July Thanks. ps i am not sure what version my phone is as i cant turn it on to find out so i put the first one.
Solution: There’s a number of possible reasons why your Note8 fails to power on after crashing. Let’s discuss each of these causes so you’ll know how to deal with them.
Android and Battery needs calibration
Sometimes, Android OS may lose track of true battery levels after running for a long time. When this happens, premature shutdowns can occur. To ensure that this does not happen, you want to regularly recalibrate Android and the battery for at least once every few months. Here’s how it’s done:
- Drain the battery completely. This means using your device until it powers down by its own and the battery level reads 0%.
- Charge the phone until it reaches 100%. Be sure to use original charging equipment for your device and let it charge up completely. Do not unplug your device for at least two more hours and also don’t use it while charging.
- After the elapsed time, unplug your device.
- Restart the device.
- Use your phone until it completely runs out of power again.
- Repeat steps 1-5.
Android is a sophisticated software environment and there are millions of possible points of failure at any given time. While developers have made Android relatively stable for millions of devices running this OS, not everything can be anticipated. Sometimes, bugs can pop up without any apparent explanation. To minimize bugs from developing, you should install any available updates. This applies to both Android Operating System and apps.
Operating System bug
Another common reason for sudden reboots can sometimes be due to operating system bugs. To see if the problem is Android-related, you want to factory reset your Note8 and observe it for a few days. These are the steps to factory reset your device:
- Create a backup of your personal data.
- Turn off the device.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
- Press the Volume down key several times to highlight ‘wipe data / factory reset’.
- Press Power button to select.
- Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
- Press Power button to select and start the master reset.
- When the master reset is complete, ‘Reboot system now’ is highlighted.
- Press the Power key to restart the device.
- Let the phone run for 24 hours without adding any apps to see if there’s any difference.
Should the issue remain after a factory reset, the cause is most likely hardware-related. Make sure to contact Samsung so they can do some hardware diagnostics. They may check the battery or the motherboard and may ask you to pay for repair or replacement. Be sure to review your warranty terms to know if your device is still covered or not. For carrier-provided phones, carriers can also provide a phone replacement so you want to contact them for help as well.
Problem #3: Galaxy Note8 cannot swipe to answer calls
After the latest update to my phone I cannot swipe to answer certain calls. It gives me an option to send a text to the caller. I can call them though. I’ve checked to make sure they are not on the blocked call list, I’ve disabled AT&T driver mode because that kept coming on even when my phone was on the table. My husband is having the same problem with his Samsung S7 but it’s only on certain calls. Have soft reset quite a few times and still doesn’t fix it.
Solution: This may be due to a bug with the Phone app. Try clearing its cache first to restore it to its defaults. Here’s how:
- Open Settings app.
- Tap Apps.
- Tap on More settings at the upper right (three-dot icon).
- Select Show system apps.
- Find and tap your app.
- Tap Storage.
- Tap Clear Data button.
- Restart your Note8 and check for the problem.
Alternatively, you can try to ditch the current Phone app you’re using and replace it with a different one. If you are using an AT&T app, you can switch to the stock Samsung Phone app or vice versa. There are many other free phone calling apps that you can get from the Play Store for this purpose. If a second phone calling app works but not the first one, then you have an app-specific app. You should contact the app developer to report the bug.
Problem #4: Galaxy Note8 won’t connect to network after repair
I had a problem connecting to a network. I have followed every fix on Google to try and resolve this.
I took phone to a local repairers and he told me it was the motherboard.
I have fitted a new motherboard and still have the same problem.
I have attached a Dropbox link with screenshots and videos showing the problem – The only thing that is left is maybe there is a problem with the aerials although I am getting a signal strength of -67dBm. Is there a way of checking them? Have you any other ideas please? I am using a Note8 with a PAYG UK card in Spain.
I never had a problem till I replaced the rear camera. then it would not connect. The SIM works in other phones and I tried a friends SIM in my phone and get the same problem.
Solution: The initial repair you did must have damaged the network chips. This can sometimes happen when amateurs tamper with the hardware. This may be the reason why the problem persists even after putting in a new motherboard. We are not in a position to tell you what the exact situation is as we are unable to examine the device ourselves. We suggest that you seek help from a professional that can physically check the device and run hardware diagnostics on it.
