Hi all,
this is my very first post here on xda, so please forgive me if this is not the proper section for my thread. I searched for other thread about similar issues, but I didn't find anyone. I'm Italian, so I even hope to not being wrong in English writing.
I recently bought (on November 2014) an Huawei Ascend Y550-L01 (Android 4.4.4, EMUI 2.3, ROM B137), coming from a (Portuguese) Samsung Galaxy Y Pro GT-B5512. Soon I experienced a very strange GPS behaviour: GPS turns itself off. No problem in signal fixing, nor in quality or precision. It simply deactivates.
First I noticed this using the OruxMaps app (which works fine on many phones, even my old one), simply recording the track. Indeed, at the beginning the app was being killed (because of the integrated task-killer) when screen was off, but after setting it as a "protected" app, when I record a track, GPS works while screen is on and, if screen turns off, then most of the times (not always) GPS is deactivated from within Android settings.
I even received (from the purchasing time) some GPS errors while in the home screen... I don't remember exactly that error, but in a fast Internet search it was told being caused from the weather widget, precisely from the "actual position" setting. I deactivated it and added manually my town and those errors were gone.
Then I noted another strange behaviour: GPS turns off even in standby, during night. It is on "extreme precision" on evening and it's off at morning. Sometimes I notice these deactivation (in the notification menu or into the energy saving widget) while I'm using the phone (but always when screens is off), without any error or message popping out... It simply gets deactivated.
Any other experiencing this strange issue? What could be the cause? I sent a mail to official support, but they asked me to take the phone in a service point... I can't stay without phone, so I would like to avoid this if it's not strictly needed.
I think it's a ROM issue (said that even in the mail), but unfortunately still there is no alternative one (or at least I found none). I think also that (almost) every app that uses GPS suffers for the same behaviour I faced using OruxMaps.
PS: phone IS rooted by a couple of week, but I'm facing this issue from the first day.
What the hell is going on? Any help, idea or trying suggestion is appreciated...
Many thanks!
Up?
I also see strange problems on the Y550-L01 connected to GPS.
In my case the GPS does not disconnect completely, but during car navigation the signal gets lost from time to time (tested with different navigation apps).
This is only the case when the Y550 is NOT connected to the charger. If I connect it to the power supply, GPS works quite reliable and accurate!
For me this sounds like a software problem (maybe connected to a power saving mode?). I hope a firmware update will fix this soon.
Even to me this is a firmware issue. Before of your answer, I was really beginning to think it's a fault of my phone. Now that I'm not the only one, I went back to think of a bug.
If it is a power save problem, then try to use this app to stop the power save mode :
https://play.google.com/store/apps/details?id=eu.thedarken.wl
(ultra light : 35K, free/no adds)
"Wake Lock gives you control over the Android Power- and WifiManager.
For example, you can force the PowerManager to keep the screen on or have the CPU still running in standby mode or make sure the Wifi connection keeps running at full performance.
You can use it on any android phone or tablet.
Use it to keep the screen on in full brightness or dimmed mode during movies or slideshows.
To make sure the CPU is still running in the background doing your tasks when you press the standby button."
Thank you for the report.
It seems that the new huaweï G620S has the same GPS problem :

Any news of an Huaweï update ? Hope yes...

Hi! Better post your question in our small Huawei Ascend Y550 thread. Maybe there someone of us can help.
If you understand German:
http://www.android-hilfe.de/huawei-...gation-unzuverlaessig-nur-im-akkubetrieb.html
These folks have the same proplem, but no solution.
Try it while a charger is attached.
Been running CM10.2 JB Unofficial for a short while and liking it. I occasionally SSH into the phone (via SSHDroid) to do stuff at the command line ... recently it has become super-laggy, like I type stuff and it doesn't appear for a couple of seconds. I can't think of anything that's changed. Just for yucks, I changed the CPU governor to Performance so that it always runs at full clock speed. Didn't help, so I guess the problem has nothing to do with CPU speed. Wifi speed test from device seems okay, wifi is set to "keep on during sleep: always." I'm at a loss, since this came on seemingly out of nowhere, and the Android touch interface seems to be normally responsive. Help?
I had a Mi4i for a year. It is a great piece of hardware, much better than all my previous phones (3 sonys, 2 samsungs, 1 motorola). When CM came, it got overall good, nut just hardware.
I mean MIUI has some nice features, like permissions etc, but also there are huge flaws. Read on...
So I have for a Redmi 3 Pro for a week now...
The good:
Unlocked bootloader.
Build quality is superb. Screen is good (720p is perfect), overall feel is good as well. Battery holds 2-3 days easily.
Fingerprint reader works fine and quickly (under 1sec.), but you have to place your finger "correctly" and have no skin issues. Camera is not too bad but not as good as Mi4i.
Also it is very responsive and quick, much better than Mi4i and all other phones I had. Even when preloaded with many apps.
Backup/restore function works beautifully. Just fully set up your device and do a backup from MIUI menu. Then you can wipe it and load different (stock) ROM version, or rooted xiaomi.eu dev version. All apps are restored quickly and work well.
Mobile signature works well on both SIM cards. Which is great, as not all phones managed that. *cough* Samsung S4 mini duo *cough*.
The bad, same as Mi4i:
1. bluetooth earpiece will lose connection when talking. It drops connection or heavily distorts the audio randomly. But youtube audio plays well on earpiece. Probably something to do with sleep?
Also problems keeping connection to Pebble watch: notifications do not come randomly, sometimes it gets unlinked an is quite a task to get linked again.
2. Apps get closed in the background randomly. Skype, Viber, Hangouts, Whatsapp, email, Pebble, and even calendar... You just stop getting notifications. Extremely annoying when WhatsApp Web stops working every 15 minutes on your PC due to lost connection to your mobile.
I have investigated this further: allowed these apps to autostart, locked them in recents drawer, disabled memory optimizations in performance menu, etc. It improved a little, but still remains an issue.
3. Widgets crash randomly and after restart. For example non-stock clock widget and calendar widget. They just stop updating after an hour or so, also after restart. After another restart they completely disappear.
So all of these issues seem to be connected to some kind of power management issue perhaps? Is there a fix available?
On Mi4i, i have never found a fix and could not use bluetooth handsfree earpiece until CM support was added. On CM13 it works just fine, so definitely not a hardware issue.
Scared from MIUI's PM A clean Android supporting fingerprint scanner would unlock the phone's potential greatly.
I hope in CM12/13 with Pro features support soon.
2. On dev rom you can change Memory optimization settings from Developer options. If you lock app by pulling down from Recents it should not get easily closed.

Yes, I have tried that and still had problems.
Anyone had any success solving bluetooth issues? BT worked perfectly with CM on same device. Maybe it is possible to swap out some drivers?
I have decided to give the Nougat for A3 2016 (A310F) another (and another) chance before returning to Marshmallow but I've had some issues - please let me know do you experience similar problems (Nougat only!).
I've upgraded to Nougat by flashing via Odin DBT code package and went from XEO Marshmallow which did not have any of the described problems.
Was running: Android 7.0, Baseband: A310FXXU3CQE7, Build: NRD90M.A310FXXU3CQE6, Kernel: 3.10.61-11350514
To confirm the below I've reflashed back to 6.0 and flashed 7.0 again (same XEO for 6.0 and same DBT for 7.0) also did factory reset and also added wipe data/cache to the test procedure which helped in couple of cases.
Issues I found with 7.0 so far:
By design:
1. Too small UI elements:
Very small single-line notification slider containing the buttons like enable/disable wi-fi, etc. Previously on Marshmallow and Lollipop it was big enough to handle it without problems. Now (thanks to DreamUX?) it is too small (it is much better on my wife's A510F after Nougat upgrade as the buttons can be way easier pressed without accidentally pressing the button to the left or to the right). This one is quite annoying but probably just because the DreamUX (or whatever it is called) has been designed with "bigger phones" in mind...
2. Flawed Power Saving:
There is absolutely no setting in the OS to set the list of apps that I want to run only in foreground and when entering background should be put to sleep (there is such setting in Marshmallow and I used it to have control over the battery life). This causes the battery life on Nougat to be quite disappointing.
FIX: Flash TWRP (see the TWRP thread for details), did wipe of everything possible. Flash back official 7.0. Currently with normal usage - taken from charger at 06:00 currently 15:40 - battery level decreased from 100% to 88% (previously 8-9 hours on battery after full charge only) I susspect that this may be connected with the software I had installed in the past and some leftovers. So installing 7.0 in cleanest possible way did the trick here.
3. Slow battery charge:
Battery is charging quite slow (location off + wifi off + 3g on + phone not being used (periodically reviewing only the status of charging). Full charge from 30-40% to 100% in c/a 4 hours. Tested wipe data/cache - did not help.
All the time:
1. Crashing Samsung Keyboard (if other used):
When used any other keyboard (tested on Swype and Hacker's Keyboard) from Google Play - everything works fine until I click (be it by accident or intentionally) the emoticon icon (near the send button) while either writing a text message or using any other app where this button is available. The result is Samsung Keyboard (?!) crashing (which is odd as another keyboard is being used at the moment) - after the crash no keyboard is available until selected from the settings General Management\Language and input\Default Keyboard
FIX: Do the wipe of data and cache.
2. VPN not working:
VPN does not work (any attempt to establish PPTP connection fails with the built-in software). Tested wipe data/cache - did not help.
Fixed itself after some time... Now it's working. Either magic or this cannot be tested straight after setting up the OS...
3. Battery drain / decreased life on battery:
Nougat is consuming far more battery than Marshmallow (20% of battery taken in one hour while driving to work (one hour) browsing the web and listening to music compared to 6-8% with Marshmallow). Tests made after wipe of data/cache.
FIX: Flash TWRP (see the TWRP thread for details), did wipe of everything possible. Flash back official 7.0. Currently with normal usage - taken from charger at 06:00 currently 15:40 - battery level decreased from 100% to 88% (previously 8-9 hours on battery after full charge only) I susspect that this may be connected with the software I had installed in the past and some leftovers. So installing 7.0 in cleanest possible way did the trick here.
Often:
1. Stuck "Call" button in UI:
Inability to click "Call" button from the contacts if often calling several contacts (UI seems to lock for 5-15 seconds). To reproduce: Go to the phone app - select contacts, then tap on any contact name (not a picture) - four buttones called "call, message, video call and details" will slide - try tapping "call". Repeat calling several contacts - the UI hangs for couple of seconds making clicking "Call" impossible (home button however works)
WORKAROUND: Swipe finger on the contact to the right of the contact or recently dialled number to start dialling (this always works and does not trigge this bug).
Quite often:
1. Mysterious "installations":
Every couple of hours a notification pops-up that something is downloaded but there it is too quick to notice what was being downloaded, where, etc. It happens regardless if restored to factory defaults (seems to appear also on my wifes A510F after Nougat upgrade). It was not related to apps like messenger or instagram being updated by themselves as this feature was disabled in the settings.
FIX: Do the wipe of data and cache. It seems that the "mysterious downloads" was unsuccessfull attempt to update Android Instant Apps ( https://developer.android.com/topic/instant-apps/index.html )
Rare:
1. Blackout:
The screen turns black. After the restart phone boots up but once started again it defaults to lowest brightness level and need to be adjusted.
FIX: Do the wipe of data and cache.

I have, so far, experienced none of the things you have mentioned. Google keyboard works great, no random installations, call works perfectly fine.
VPN won't work
i have the exact same call problem as you have but i also have some random android.phone crashes WHILE ON THE SKYPE APP
WHAT IS HAPPENING
I've got no problems I wiped from fast rom. V2. To advance three. My phones fast. But always cold. So I know there's power wasted.... If I were you download eset file manager.. There's a file logger. I also use greenify.
I'm not saying that official Samsung release of Nougat for A3 2016 is a piece of crap but just could be better (or it lacks some testing).
It has some minor flaws either that you need to get used to or you need to find a workaround if too anoying.
In general Nougat was responsive and working quite well. The design of caller UI and the notification dropdown were particularly most irritating for me since I used them both lot of time - that's why I've decided to returned to Marshmallow.
I know that I could used Greenify, etc (I used it some time ago on my rooted Galaxy Ace2) but Marshmallow with all it's features had given me "out of the box" everything I needed for work. That is why Nougat was kind of disappointment as it required some tweaking. I've also spent some time with reseting to factory defaults or flashing 6.0 and upgrading again to 7.0 and flashing again... etc... but the issues still were there. I susspect (but cannot confirm this as I haven't made any research on it) it may be kind of "per device" issue. I had similar problems before with Galaxy Ace2 as the same model (i8160) had two different versions (without any visible differeces/different firmwares etc) which had two different LCD screen whereas devices with S6D27A1 LCD were working all the time fine and devices with the LCD WS2401 (mine was having this one ;] were the lower quality ones and had issues with some firmwares, etc). This could explain at least that some people do not have any issues after the upgrade and some do have.

As for android-phone process crashing I would suggest making wipe of user data and cache partition / reset to factory defaults. This does not seem to be related with the firmware (I doubt that Samsung would release a firmware which is causing that type of issue.

Sadly I don't have Nougat now (I've returned to Marshmallow) and cannot confirm but on Marshmallow VPN works fine.
BTW: Does VPN not work at all, or does not work only with 3G or Wi-Fi?

I returned to Nougat just to play around with it once again (I hoped to get rid of the battery drain issues, etc).
I can also confirm that the VPN support is broken (connecting is not possible) at least with the built-in VPN tool.
A310M Nougat is now available. I flashed it with ODIN over a rooted MM with xposed installed, no wipes.
Everything is working just fine, wifi, bt, calls, keyboard (both gboard and samsung), data, sms, alarm clock, camera (front/back, stills with effects and video), new themes gallery. I'm having just a few hiccups in Chrome with heavy pages. I have no complaints whatsoever.
I kinda like the new layout and icons. Seems fluid. Battery seems fine too. In MM I get around 2 days, +6h SoT with lots of internet browsing, instagram, utorrent, youtube (when I feel lazy to use my desktop), calls (maybe a couple of hours/day), whatsapp all day long, acdisplay always on. I don't use 3g/4g that much because I hardly need it, wifi available in home, college and work.
I'll keep an eye on the battery stats. Gotta let it settle down a bit as I get used to Nougat. I'm really loving it so far.
So after couple of days spend testing, etc. it seems that for me all problems are more or less gone. Basically only two real problems are left:
1. The UI designed clearly for bigger phones and not quite comfortable, but some workarounds are possible.
2. Not working VPN (which is something I really use very very very rarily)
The solution to most problems is instead of insisting on upgrade from 6.01 (which seems to be severely flawed) to do the wipe of data and cache after the upgrade and configure everything from scratch.
However if this won't help (like in my scenario) - you can consider installing custom recovery (please note the warranty void and stuff) - TWRP and wipe evertyhing from there and... flash 7.0 again. To be honest - this last option fixed most issues for me and left me with pretty usable phone (again).

Hello all,
Unfortunately I observe a significant power drain which was not observed with android v. 5 or 6. On top of that I have some issues with "GPS signal lost" during map navigation. It's going even worst when battery saving functions are on
I tried different "tricks" suggested here, such as wiping cache but with no luck. I'm considering going back to android 6
I'm running nougat in one SM-A310M. To be honest, I'm not experiencing nothing bad. The battery is ok, system stability is ok, performance on and functionality is quite better.
Some things that I've to say:
1 system memory WON approximately 800 MB of free space
2 RAM usage is equal to marshmallow, but too much optimized (reopening apps)
3 the light sensor bugs is gone
4 mine antutu record before were around 27k. Now is ~37k. (I don't know the why, but 3D tests were listed how "unsupported" at the end of tests and now, in nougat, is ok. The RAM score is quite higher also on nougat
5 all the new functionality like notifications, recent apps button, video app can now create GIFs and the pop up blocker (goodbye SIM crazy popups) on home screen are quite useful.
Unfortunately, we don't have the multi window and night mode features, but I general, the update is positive. Nothing bad for while.
I'm attaching two images. The higher value come from nougat.
Hi
Andoid 12 (latest via OTA)
non-rooted
The problem is that while there is no problem with SMS / WhatsAPP notifications, no other ones come
Other notifications come only in 2 cases
- unlocks the screen (backlight is not enough, I have to unlock it)
- the phone is charging (then they come normally)
First, I set everything according to my own logic and intuition (it has worked well for the last dozen or so years of using electronics)
The problem still existed - so I looked online and set everything up as people suggested - THE PROBLEM STILL EXISTS
Later I found the website dontkillmyapps
I set up the entire system and applications according to the information provided
THE PROBLEM STILL EXISTS
I even installed an application related to this website that checks the killing of applications, after a two-hour test, all results came out 100% (i.e. nothing killed according to the legend of the tests)
I turned off optimization, turned on dynamic mode, turned on flexi, turned off battery adaptive mode - in short, everything possible at the expense of battery life - ZERO result
Phone unlocked - notifications come, phone locks - they come for about 1-2 minutes and end
Previously, I used A11 (I did not upgrade to A12) on LG g8s and there were no such problems
Its an android issue, not a Zenfone issue. I would just not get notifications on messanger (FB) randomly. It was the same with a S21 Ultra I had before. I always do the steps you mentioned, but it didn't solve the issue. Uninstalling and reinstalling solved it for 1-2 days, then notifications will stop arriving randomly.
I have to admit its better with A13, the notifications are just delayed, I don't think i missed one since I did a clean install about a week ago.
