I do not own a MX4 Pro, lets wait for other users to take a look at it.


i got this update by really strange way… i had an old Open Beta version… then i suddenly got a week ago OTA update for 4.5.5A (i presume it was an Open Beta too,but i contacted Meizu about it (still no answer btw) because it wasnt listed on Meizu Webpage) and today i got an OTA for 4.5.5A again… and i guess its stable one… cause size of this update is the same as my OTA… anyways installed it without Clearing Data ofc… so far all working fine… Baseband version same as it was a week ago.

I’ve just installed it with “eraze data”…

Firstable, it seems to be more reactive, the basebandversion is now the LTG_3.116.000.
Must be tested in time…
The exit of the sleep mode is now quick, home button tu return on the desktop is more quick too…
But I must take time to test…and maybe it slow down in duration, will see…

The feedback system is in chinese (help part)…and it’s now possible to let some suggestion to increase experience with mx4pro, or simply to speak about bug…I’m not sure that meizu has mesured what will follow…maybe a lot of complain…we’ll see in time…

@strider83 at first exit from the sleep was OK, but after few hours it takes about 2 seconds to turn it on… :/
Does 4g LTE work on your phone?

should i delete data?
i’m on 4.4.5A test

no way. The best is sell my phone, i report via feedback the keyboard bug since 4.2.x. we are on 4.5.5 and meizu not do nothing, all big bugs are always present, i dont understand why?! If we install other keyboard like google keyboard, swiftkey, etc that have predication system for fast write, we can’t select the middle of suggested word… cursor position always select the end of word. Without this function and using the default meizu keyboard, we go 20 years for past because it not have suggestion word, dicionary, and we need always to write the full word, even if i wrote it 10000000 times per day! They dont do noting for solve it and bring support for others keyboard apps. Please stay tune in that before buy any meizu phone. All FLYME VERSIONS IN ANY PHONE HAVE THAT BIGGGGGG BUG… they are always updating the system, but not solve any bugs, why? If dont know more in android development, please realease android L for international users… write the same word 10000000 times and no dicionary for learn that is go to 20 years ago…


@strider83 are you sure baseband is 3.116.000? not 2.116.000?
