Meizu are making some really great value phones. The operating system they come with is a skinned version of Android called Flyme. By default notifications don’t work for Facebook messenger and the Google apps most people use. This can be resolved by modifying the settings in the pre-installed “Security” app as follows.
1. Open the Play Store and install the “Google” app by Google Inc. if it isn’t already installed. Install all the apps that you need to get notifications like Messenger or Gmail.
2. Open the “Security” app
3. Open “Accelerator”
4. Open the Settings page by clicking on the cog icon in the top right hand corner.
5. Open the “Memory acceleration whitelist”
6. Click on “ADD TO WHITELIST” and select the apps for which you want to enable notifications and run in the background.
7. Go back to the main menu of the Security app and open the “Permissions” page.
8. Open “Auto-launched apps” and enable all the apps you want to run in the background.
9. Back to the Permissions page then open “Notifications of apps”
10. Enable notification for all your chosen apps.
11. Back to the Permissions page and open “App management”
12.On the “App management” page scroll down to each of your chosen apps and ensure they have “Notification” enabled. E.g. for Facebook Messenger:
13. Back to the main menu for the “Security” app and select “Power”
14. Open “Standby management” (which will have the confusing heading App management as below)
15. Allow any apps that you want notifications from to run in the background.
And finally we’re done.
I inherited a Galaxy Mini model GT-i5503t. It comes with Android 2.1 which is getting a bit old and unsupported, it is more than capable of running 2.3 and isn’t too hard to upgrade. This phone is also called the Galaxy 5 which is the same as the i5500 and i5508. These are the steps that worked for me to install CyanogenMod 7. Unfortunately you need to use a proprietary tool to flash a new Baseband image and ClockWorkMod to start with, but you can update to future CM versions without it. I’m not an expert in this so I’d recommend you redirect any questions to the XDA forums
(Google for download links)
- Remove the SIM from the phone. Backup any data on the SD card, wipe it and copy the following files on to it:
- Find a Windows computer to download and run Odin Multi Downloader v4.28.exe
- Upgrade the baseband:
- Put phone into download mode by powering off then sequentially holding Volume Down + Centre Button + Power Button
- Start Odin, select One Package and the file AMSS-I5503TAJJP9.tar.
- Plug phone into computer via USB, it should show up in Odin (if not get the drivers from Samsung website), once detected click ‘Start’ and hopefully it will copy successfully and then the device will reboot.
- Install ClockWorkMod (CWM) with the same procedure as above but instead select the file ClockworkMod-Galaxy5-v0.7.tar
- When the device reboots it will start CWM. Wipe all the data phone:
- wipe data/factory reset
- wipe cache partition
- advanced > Wipe Dalvik Cache
- Install the roms
- install zip from sdcard > choose zip from sdcard > cm-7-20120702-MADTEAM-galaxy5.zip
- install zip from sdcard > choose zip from sdcard > hotfix5-cm-7-20120702-MADTEAM-galaxy5.zip
NOTE: This one is important! WiFi didn’t work without it
- install zip from sdcard > choose zip from sdcard > gapps-gb-20110828-signed.zip
- Once they’ve all installed, select the reboot option and wait for the first boot up which can take a long time (5 min)
- Done! It’s working great for me and I can now run apps that weren’t available on Android 2.1. If you’ve got any problems probably best to check out the XDA forums
I’ve been running this version of CM7 for 6 weeks now and I would definitely recommend it. I get better battery life, it’s more responsive, the phone no longer turns off daily (like it did with the stock firmware) and I’m having no problem running newer apps.
