same problem with 4.4.2 ROM, I thought that was solved in 4.4.4, but you were using 4.4.4 with the same problem right?
i readed that in 4.4.3 this was fixed but i dont understand why you have the problem with 4.4.4

Yeah, thought it was 4.4.4 so I went to 4.4.2 and the problem is still there

Could it be hardware issue then?

I've used Able's (when I was on 4.4.4), Goldfinger, Super nexus(recent version)...and happens in all of them. So my guess it wasn't any roms. Now my guess it's hardware issue

Could an App from the play store cause the phone to lose connection?

How I updated my xt1021 to lollipop

Hello, first of all, I'm from Spain, so sorry my bad english.
Now I'll explain what I did to install the captured 5.0 OTA in my Moto E.
First I flashed stock 4.4.4 ( the indian one, My phone is from Spain, but flash went okay) then I flashed TWRP recovery via fastboot. Later I downloaded flashable zip by @tech_master and installed it via TWRP. And voila, my xt1021 have lollipop 5.0.2
Later i'll post screens.
again sorry for my bad english, and I hope this helps you guys to get LP on xt1021

Give this man his thanks!
Nice, I also wanted to flash indian version but I was a little bit of afraid, because I knew baseband will be broken. But seems like it's working when you don't flash the modem.
EDIT: You didn't flash indian modem, right? Because RIL wouldn't work then. (Already did that once, just fixed it by flashing XT1021 modem)

Offtopic:
I rooted the phone on lollipop to remove bloatware, I used an app on play store called root uninstaller or something like that, it removes the apps but they still showing in drawer, and if i try to open it FC ( obviusly) any mode to delete the apps from drawer too?

Download Google Now Launcher, it looks like a real Lollipop Launcher(it is officially from google obviously) and I think it'll solve the issue.

Maybe it is hardware problem, because Moto E speakers and microphone are really sensitive so they get broken really easily. But anyways, I will check it when flashing is done.

It's not a hardware issue. All sounds work (including the hangup tone) EXCEPT the in-call sound.
I tried replacing the "NON-HLOS.bin" (modem/radio) file of XT1022 ROM with the one from XT1021 ROM, still no in-call sound.
was not able to flash the lollipop zip
flashed back my country retail and calls working fine
wait for some stable zip
thnx

update to marshmallow or stay on lollipop?

I have a factory unlocked g3 d855(32 gb).I wanted to update to marshmallow, so I've done some searching, and people reported a lot of bugs. They also mentioned bug fixes to some of the problems, but it doesnt feel worth it. Can anyone who has experienced the official marshmallow update please advise? Is it worth the update?
Thanks in advance
Its really worth it, trust me.
And if you don't like it, you can always downgrade.
Yes it is definitely worth it. There are some bugs but the improvements over lollipop outweigh them for sure!
I would say not for the moment
I have 2 phones both with 30b stock firmware, wi-fi is driving me nuts, once the screen is off, wi-fi is off, also wi-fi disconnects randomly when using the phone; new graphics and menu are nice, but wi-fi problems are a major bust (I have tried a major of tips and tricks for this problem but still no solution)
I will try the new 30n stock firmware and see if it fixes the issue, if not, I am back on lollipop
Hey man can you tell me how to downgrade from 6.0 to 5.1

Probably the DSDS in the Qualcomm X10 modem that is causing problems with active/passive SIM-card if both need 4G as the modem can only supply one SIM-card with active access at a time.

Flash to 3.5.6 with a clean flash, use that for a day and see if there are any network issues or reboots. If not then flash whatever custom rom you want and test again.

Maybe your LTE network isn't stable. Try selecting LTE only in sim settings.

Correct if your provider doesnt support volte then you're **** outta luck. Just like me. But if you are still having full network drops and the change in modem didnt help then it is probably hardware. I redownloaded 3.5.6 yesterday from oneplus and reflashed and have stayed on that over yesterday last night and today, and so far no full network drops, so if you flashing the modem/firmware from anywhere other that oneplus it may be corrupt and messing up your modem. But this might just be me.

First I update via OTA. When i face this issues i flash (BTU) from sammobile via odin. No not rooted (i have never root my device). And i wiped before and after update. Yes correct modem PLT. The Latest stable build PLT (BTU) and tried (O2C) too but same problem.
Exactly the same problem here with G930F after updating via ODIN to DPLT (BTU Stock without touching anything!!). If I downgrade to 6.0.1 WIFI works again. If I move to AOSP roms based on 7.1.1, it works perfectly.
Am using stock DPLT bootloader, modem, csc. The problem started with ZPL3 beta version.
same exact issue here
G935FD updated to official nougat using odin, wifi no longer works.
if I install beta nougat it works again. any help?

I have a G930F, so it's the flat screen model but i'm having exactly the same issue.
Flashed BTU CSC, not CSC home. let it boot, went into recovery, wiped. WiFi still has issues even after a clean flash. The ! symbol sometimes appears and I lose access to the internet until i turn it off and on again.

I don't know as I haven't looked into it yet. All I know is Oreo repartitions the internal memory so I don't know whether rolling back will undo this (probably not)

Hi,
My S7e has just upgraded to 8.0.0 and is now having the same wifi lag issue. Did you manage to find a fix?
Thanks
Ady
I tried a different kernel and now both my.wifi and Bluetooth are working like a charm. Before on Oreo my wifi switch went completely gray and in order to get the Bluetooth to work , Everytime I had to do a network reset. But now it's working great.
I had another issue, my security was pattern unlock and it would take a minute for it to unlock and sometimes in between the screen would turn off, that problem also got solved with the kernel .

You do not have the same issue as us and as far as I'm aware a kernel swap would mean our devices had to be routed.
