Huawei Mate 8 problems and solutions

The Huawei Mate 8 is as close to perfect as a phablet can get, but like any smartphone or tablet, it can encounter the odd problem from rogue apps, bugs in the operating system or just the wear and tear of constant use. If your mate isn’t behaving quite the way you’d like it to, we can help. These are the most common Huawei Mate 8 problems and the solutions we’ve found.

"Camera failed" warning

Some Mate 8 users have reported a worrying error that pops up after a few days of normal use: “Warning: Camera failed”. As the message suggests, the camera has stopped working and rebooting the Mate 8 doesn’t appear to fix it.

The first thing to try here is to go into Settings > Apps and locate the Camera app. Force stop it, clear its data, clear its cache and restart your Mate 8.

No luck? The next option is to clear the system cache. To do that, turn off your device and then press Power, Home and Volume Up simultaneously until the device starts. When you see the system recovery screen, use Volume Down to navigate to Wipe Cache Partition and Power to select that option.

If none of those things work it’s time to go back to the retailer, because your camera may have developed a hardware fault.

You can’t install a custom launcher

The Mate 8 may be a brilliant phablet, but there are a few bugs in its software. One particularly irritating one is that you can install a third-party app launcher, but it doesn’t set it as the default.

You might also find that some apps revert to their default settings for no good reason. We don’t know of a workaround for these issues, but we’d expect Huawei to solve them in its next software update.

Excessive battery drain

The Mate 8 has an enormous battery and the latest, most efficient version of Android, so battery life shouldn’t be an issue. If it is, something is clearly not the way it should be.

The simplest way to find the offender is to go into Settings and look up your battery usage; this tells you what’s using the most power on your device. Some apps are known to demand more power than we’d like – Facebook recently hit the headlines amid claims that it reduced battery life by as much as 20 percent – and uninstalling them can be a simple way to solve your problems.

It’s important to note that not all apps are using energy without good reason. For example, you’ll get much less battery life if you’re hammering away in a 3D game all day than if you use your Mate for texting and the odd bit of internet browsing. Similarly, using location-based apps such as navigation apps can suck battery life at a fairly alarming rate.

Camera takes too long to launch

There isn’t a fix for this, but there is a workaround. Launch the camera app before you’re planning to shoot anything. Waking the camera from cold takes forever, but once you’ve loaded it, switching to the camera from another app is much, much faster.

Wi-Fi or Bluetooth won’t connect

All phones experience connection issues from time to time. The most likely culprit is the infamous Wi-Fi problem that seems to affect every Android device, where you suddenly can’t connect to favorite networks.

In many cases the culprit for that one is your router and a reboot of the router fixes it; if that doesn’t work, try restarting your device too. Still no joy? Forget the network in Settings and try adding it from scratch. If the problem is Bluetooth, try deleting paired devices from Settings > Bluetooth and re-pairing again.

Battery is charging slowly

Does your Mate 8 already have a reasonable charge? Batteries charge more quickly the more depleted they are, so a dead battery will charge to 50 percent faster than a half-full one will charge to 100 percent.

There’s another possibility, however, and that’s the use of a third party charger: while the Mate 8 supports fast charging, third party chargers don’t seem to deliver the juice that the Mate 8 needs for fast battery charging. For the fastest charging, you’ll need to use Huawei’s own charger.

  • What's the hell going on my device I do not understand....

    While I updated new version EMUI 5.0 android 7.0, the battery is almost 60% and I fell to connected in the charger, surprisingly it's not charging.
    I shut down the device and connected to the charger Its support for just 2 seconds again disconnected. I try couple times shut down, restart
    while I connect charger its blink sound of charging and also shows the screen charge of mobile, then just 2 seconds later automatic lost of charging.
    Its happen when I restart mobile its only one time shows connected charge than a second automatic lost.

    But while I shut down the device and connected charge, it's continually connected and disconnected, its happen second by second and sometimes its charging mobile so I scare to charge also. I went Brussels Huwai customer care & service team told me issued charger than I bought a new charger, charging place still facing the same issue. I Try from laptop also from the USB cable.
    I better explain I can charge sometimes only, not regularly. If it's charging then I pull out cable again I face the issue. this issued come when I update new version, I am sure mobile charge port and charger working fine but when I update new version software that time my wifi not working fine, it takes time to download software almost 2 days. That time I can,t download software contumely. I think that the software issue happens like that.

    Need your support to fix the problem.

    Recently, my mate 8 started rebooting itself constantly for no reason and the battery appears as if it is 60/70% (or whatever the number is) but after the phone reboots im left with 0 or 1%.

  • I have an unusual issue with my mate 8, in that when trying to use it as a wifi hotspot, my laptop can connect without issue, the phone can connect to the internet without a problem, but the laptop cannot get any internet access, any one with any bright ideas on this.

  • I have a problem with Huawei Mate 8 Sintific Calculator when it comes to sin and cos it gives wrong values, please advice

  • There are 2 issues I faced:
    1. When using Skype, video call, once you turn your phone to horizontal or vertical from one position, the camera froze. Needs to restart the phone every time. Clearing the the caches and force stop the camera doesn't work if no restart.
    2. NFC doesn't not work. It can read a FlashPay card or another device with NFC.

    Other than that, the phone works fine. Camera is good.

  • I've had the mate 8 for a month and I absolutely adore it. Only problem I have is that when I write and use a word the phone doesn't recognize, the moment I end off the sentence it jumps back and deletes the word. Is there a setting I need to change to stop this? Its driving me up the walls.

    One annoying thing I'm finding with this phone is I can't make it automatically use the same sim it used last time when calling a contact. This makes calling with a car kit hard since I have to select the Sim on every call. Further it's working perfect, if anyone has a solution for this please let me know.

  • Some of the widgets does not update.. i tried Huawei Launcher, as well as google laucncher and nova as well
    any solution for that??

  • I do not remember my password to log in my Mate 8 what can I do that is not factory reset???

  • WiFi connection gets difficult.

    Try to enter advanced wifi configuration and setup a static IP address (instead of automatic DHCP)
    Uses to work.

  • How about when fast charging not working anymore after my friend used my charger to charge his iphone?

    • Fast charging can be due to the charger and also the micro USB cable. Did you try using another cable and charger?

  • My Mate8 reboots itself for no reason-have sent it back and a month later I got it back with no explanation as to what is wrong with it but it is still doing it! Please help-I really love this phone but this is very annoying

  • My hubbie is considering to buy this phone. We're not too sure 'cause the camera bug. Did you guys experimented real issues with the camera??
