49pus7503/12 lost TV signal randomly problem - Android Q&A, Help & Troubleshooting

Hi,
i'm experiencing a strange issue on my 49pus7503/12 (oreo, latest system update), randomly and suddently i lost the TV cable signal:
1 time happened during standard TV watch
4-5 times after Netflix use > open netflix, watch anything for 1-2 hours, click on TV button >>> no signal found
when this problem happened i've tried to:
update channels list (the process is completed but nothing changed)
re-install (the process is never completed, stuck at 50% and the issue with signal is not resolved)
turn off - turn on the tv (nothing changed)
the only way is to unplug-replug the TV electric wire. in that case Android restarts and anything works fine (also the re-install channels process can be initialized and completed 100% without problems)
Phillips support told me to de-activate HBB, and now i need to check if the problem will occur again, but i'm not so confidenti about it.
Has anyone experienced similar issue? do you have any hint?
thanks in advance!

[Q] Cubot One Bluetooth Connection Issues

I have a Cubot One, using the G800_CUBOT_D1_V0.8_20140124_MJK firmware (4.2.1) - it was previously on the 0.6 firmware and had the same issue.
What I have experienced is that when connecting to a device with Bluetooth - in this case a Sony SW2, but have also tried Bluetooth headsets - it has problems pairing.
The phone sees the BT device as an available device, and when I select it, it starts the pairing process. Initially it seems to be ok and successfully pairs for 2-5 seconds, the the device is relisted as an available device, but not connected. I have had success twice. The first time was immediately after rooted my phone, and this was ok for several days, even rebooting my phone and the watch didn't seem to cause the issue again, but then it randomly stopped working. I was unable to connect until flashing with the 0.8 ROM. At this point is was again working for about 24 hours - even better than before - until I switched the watch off. Since then I have been unsuccessful in pairing again.
Interestingly, when I try to pair with my Galaxy Tab 2 I have the same problem, UNLESS I initiate the connection with the tablet, then it is fine.
I know that there were problems with the Bluetooth stack on 4.2.1 when it first came out, and it may be related to that, but can anyone offer suggestions as to what else I can try?

I have the same problem with the MXQ Pro+, with random freezing. Internet search suggest something to do with the CEC on the TV setting for HDMI. I toggled with the Setting but still did not fix the problem
I noticed that the box crashes every time i put it in standby and then wake it.
If I shut it off and then restart, not a crash.
anyone else?
(or at least a new firmware, my hope its fault - 07-06 version- and not because of hardware

and the power indication lamp fluctuate (Red -then -Blue) ----- I try to make reset from the (AV) input many time but, No Responce ...no any output from the HDMI,
Need help please

Galaxy alpha randomly shuts down, will boot loop unless plugged into AC power

I have a galaxy alpha that will randomly shutdown when off the charger and will just boot loop until it is plugged back into a power source. A spare OEM battery was purchased separately and this problem occurs with the spare battery as well. The phone is running rooted stock android 5.0.2.
Same over here
I have the same problem! It started a few days ago, and i don't installed any app...
Battery is Stock, No damage on entire smartphone, and it keeps shutting down randomly for no reason and only starts when plugged into AC power too...
I'm on EpsilROM 3.9.8
So anyone else with this problem? Anyone can help?
Guess we are out of luck FelipeBazz, I am running stock rom but rooted. I suppose I'll try a factory reset and see where that gets me.
I've changed the battery, now it works fine again.
Just reporting, for people with the same problem know what to do.
I had the same problem (symptoms were the same): The problem started a few weeks ago (after some update I guess). It was happening 10-30 seconds after 3G mobile connection started. Changing the battery or SIM didn't help.
After uninstalling the updates for Google Play Store app, phone worked *almost normal again. (Settings / Appl. Manager / All / Google Play Store / Uninstall updates)
*almost: 3g internet connectivity is lost every now and then. Also, during calls, occasionally, the other party can't her me for 1-2 seconds)

Wifi/Bluetooth randomly failing Huawei y6 2017?

First of all I know it's a crap phone.
It is not my wifi that is the problem, it happens on all wifi networks.
I didn't drop the phone or anything like that.
I am running stock Android 6.0 (no root)
I previously used a hack from this website that involved putting code through MinimalADB to mount an sd card as the main storage as this phone doesn't support apps on sd card (Did after that hack!).
On my phone randomly when I am using my wifi the wifi stops working randomly. There is no warning and no sign except only the left arrow beside the wifi bars lights up (the bars are still full). Nothing at all will load. The only solution I have found to this problem is restarting my phone. As this happens usually after 10/15 minutes of using the phone it is beyond irritating. The Bluetooth also goes and even though it says I am still connected to my headphones no sound will transmit. Mobile data still works.
If anyone can help it will be super helpful.

Android Auto

Anyone having problems with constant disconnects with android auto?
I have latest UK firmware installed along with the latest android auto and waze on my phone.
I can connect fine , sometimes I can drive 30 minutes without a disconnect, other times it is 5 minutes.
The only way I can get it working again is if I unplug the phone from the car and reconnect.
Then this happens again.
I have not made a journey yet where the phone has not disconnected at least once.
My old phone (nokia 8) never had this problem.
Im using a good quality USB cable.
Any ideas of which settings I need to change to help this issue?
Try using the phone manager app's battery settings to set Android Auto and Waze to manage manually as to me it seems that the battery management's the issue.

Works fine for me, using Waze/Spotify most of the time. Using default battery optimization for Android auto.
I'm using a Huawei cable.
You could try to the one coming with the phone to test.
Hi ,
Thanks for the replies.
Im using the cable that came with the phone in my car and it still has the same problem.
I changed the settings to manage manually, but again I plugged the phone in to my car and it stopped working after 5 minutes. I had to unplug and start again before the car would see the phone again.
There are 3 sets of settings in the manage manually option. did you change any of these?
Should say that im plugging into a vauxhall Astra 2017 car with the latest software installed on my car.
Thanks again for any help.
I've only had my UK Mate 20 Pro for about 3 weeks now, but I too am having issues with Android Auto. Initially I was getting disconnects, I think this was due to the handset trying to ask me how I wanted the USB connection to be treated - charge only, transfer files, MIDI device etc. It didn't seem to matter what I chose, it always flicked back to charge only. Or, it could have been down to the third party always-on-display app(s) that I was trialling and have since deleted.
The disconnects now seem to have stopped and it's more stable for me - I don't know why, it could due to the above deletions or a recent EMUI update (I'm on 9.0.0.210), or maybe Android Auto updated?
I now have different issues with AA, in that when I connect the handset and the Android Auto home screen comes up, there's no play button showing for my Audiobook app (Listen Audiobook Player), when I click into the app and click the play button it stays on 'getting your selection' forever and nothing plays. Incidentally I can start playing a book on my handset, but AA doesn't notice that anything's changed and stays on the 'getting your selection' screen.
The only way I have found to return functionality to normal is to restart the phone and enter my pass code - this takes me back to the phone desktop and a different error message which says 'android auto can't find any supported devices to use' (or something similar), when I unplug and re-plug all works as it should again - this is all a bit of a pain to do whilst driving, or requires me to park up.
Additionally I have noticed similar issues when switching audio apps i.e. to Spotify and then to an audiobook etc., It doesn't seem to go smoothly like it used to on my S8+
I'm using a 2017 Vauxhall Astra also ?
Ive sent a message to customer services to see if they can offer any help.
Dont know if we will have to wait for a firmware update to sort this out?
Same every single time. Did a 120 mile trip today and had to disconnect and reconnect 7 times

Do an factory reset and try it again. See if it works.

Hi, Can you all please share the model of your car ? Maybe the issue is also connected to the car, not only the M20Pro. Thank you.
My car is a vauxhall astra.
I know it is not the car at fault as my last phone which was a Nokia 8 running android pie worked fine without any disconnections.

Same car. Used a samsung a9 yesterday and worked flawlessly.
Done a factory reset on the mate and still ****s up. If it wasnt such a good camera I would be getting a different phone
I tried it on a Mercedes CLS, just for a short run. It worked fine. With non-official Huawei Cable. Just basic USB-C. Maybe I need to try for a long run to be sure about it.
Anyone tried it on a Volvo XC40-60-90 ?
Disconnects
Did you find a solution to this? my device also suffers from constant disconnects and sets the USB method to charge only and as soon as you change it just goes straight back. battery management is set to manual and all apps and phone are up to date. using it on a Vauxhall insignia 66 plate with OEM cable.
Hey guys,
The problem seems to be with a nearly full battery.
When the battery is >=92% the connection of AA drops very often.
Is anyone here with EMUI 10 to test if it's more stable?
EDIT: I've missed that today is the launch of the beta so forget my question.
Edit2: some links for the same topic.
