The problem with third party launchers

Many love the Huawei smartphones, but not their shell. Yes, perhaps it is versatile, but its design is very strange. Some users began to download third-party launchers, but encountered a problem. When you put, for example, Nova Launcher by default, then when you return to Desk, get back on EMUI. Then has again to go into the settings and set a new default launcher.

  • Most likely this problem is related to memory and power consumption. Smartphone automatically close all running in the background apps to save battery. It also affects notifications. This problem will be solved with updates.
  • Alternatively, in the settings of the new launcher, such as Nova, to fix it. Go to the settings app in the section “Recent Apps”. Click a little lock icon.
  • Nova launcher also has a setting called “Aggressive desktop”. For some users it helped.

The performance problem

After a certain time of operation of the device, some users have noticed that the smartphone sometimes slows down. There are different braking system and strange delays.

  • Download the app Greenify from the Google Play store. With it, you can see a list of apps that are active during operation of the device. And then you can change the settings of these applications. This should help to mitigate any slowdown in the system.
  • There are spy apps that really are a bad influence on the device operation. In order to calculate them it is necessary to reboot into safe mode. If the problem persists, you should remove a number of the downloaded applications. In extreme cases, you can reset the device to factory defaults.

The problem with autonomy

Huawei Mate 9 has a great battery 4000 mAh. The smartphone is considered as a very stand-alone device. But some smartphone users started to experience battery problems. The device can work only 6-8 hours, which will agree, with such a large battery is very small.

  • Follow the statistics of battery consumption to see what application is “eating” charge. If so, then delete it. Try to find an alternative in Google Play Store. Some owners of the problem was due to sync Google Calendar and mail apps Exchange.

Problems connecting

As with any other new device, you might encounter some problems with the Bluetooth connection and Wi-Fi. Met the same problem with connecting to a closed Wi-Fi.

You cannot connect to a secured Wi-Fi:

  • Smartphone easily connects to outdoor access points, but you may encounter a problem connecting to the router with support 802.11 EAP. Click “Save” or “Connect” is inactive and you cannot enter a password. To fix this problem easily. You need to change the settings for CA certificate from “Unspecified” to “Do not validate”.

Common problems with Wi-Fi:

  • Disconnect the device from wifi and restart the router. Then again try to connect to the network.
  • Make sure that your device is turned off power-saving function.
  • Download the app wifi Analyzer to check how crowded your channel. After this, switch to a free.
  • The Wi-Fi settings open the list of saved access points and remove the one which are unable to connect. Then re-authenticate.
  • Make sure that the router has the latest available software.
  • Make sure the app and your device is also updated.
  • Try to manually set the MAC address to the device and then check if he has access to the MAC filter of the router.

Common problems with Bluetooth:

  • If you have problems connecting to the car audio system, try uninstalling the device and then re-complete the connection.
  • Make sure you have completed all requirements in the connection.
  • Check Bluetooth settings.
  • Remove all the stored pairing, and then re-connect to the device.

Problems that can be solved only with software updates

There are a number of specific problems faced by users. Unfortunately, there are no easy fixes or workarounds. In these cases, the only option is to wait for an official software update. Some of these problems are listed below.

  • Some users found that on the lock screen there is no controls when listening to music. This means that the phone needs to be unlocked to pause or switch to another track. This problem is most often found in the Spotify app, but some have encountered it in other streaming services.
  • Some owners have problems with the sensitivity of the touch panel along the right and left side of the screen. Huawei has reacted to this and soon should get a special update that will solve this problem.
  • As mentioned above, in some devices has detected a problem with aggressive control of RAM, which is not really normal to use third-party launcher on your smartphone. Huawei is already working on a solution to this problem.
