Marshmallow OTA Loaded With Bugs

After months of waiting for AT&T to update our 0 phones, the update is quite buggy. Are there fixes out for the various problems with Marshmallow?

1. WIFI connectivity comes and goes. It is difficult to overstate the seriousness of connectivity bugs for power users on a phone with no removable media. My WIFI connects to a network (usually, but not always) but it won't stay connected long. It will drop out and reconnect seemingly when it so chooses. It does seem to work to force a reconnect by cycling WIFI on and off. This bug is horrible.

2. Battery drain is not something I've complained about on this phone til now. If I don't KEEP my phone in ultra battery conservation mode, with regular use the battery lasts a couple of hours TOPS.

3. Mobile data connectivity is now buggy as well. Like the WIFI, it comes and goes. Though it is more consistent than the WIFI.

4. Facebook disconnects constantly. I don't know if this is only because of the mobile data and WIFI connectivity issues or if it is a specific app problem with Marshmallow as well as the WIFI/network issue.

What bugs are you all seeing and are there fixes available?

Meizu m2 note Flyme not loaded

Hello. I ask for your help. I have the following problem. Bought a mobile phone Meizu 2Note 16gb from Aliexpress about a month ago. Decided to update the firmware and the phone fell into eternal reboot and is not included. When you enable the mobile phone turns the icon "Flyme" Tried different firmwares didn't help either. Me with different Russian-speaking forums advised me to contact you. Please help me. If you do not mind could you give me factory firmware for my mobile phone. I have tried lots of firmware and when loading I only saw the icon of "Flyme" and nothing more. Here is the data from my mobile device:SERIAL NO:81UEBM4227LJ CMIIT ID:2015CP2130 Bought for Russia
