My phone is model number EVA-L09, running EMUI version 5.0.2 and Android version 7.0.

I've got a slight idea as to a possible reason that Bluetooth isn't working on my phone. My idea is that as lots of the stock apps are missing, that could mean that some internal files could be missing too, such as the ones that would allow Bluetooth to work, or at the very least, turn on.

I managed to replace the screen and I am able to use my phone again, YAY!

but...

Ever since I replaced the screen and battery I am now having a major problem.

First of all, it kept coming up with a message saying, "Temperature too high, functionality limited". After noticing this message I noticed the lightning bolt charge symbol had disappeared. My phone was no longer charging so it seemed. And then the phone died even though the battery was on 35%.

So I then immediately disassembled the phone and switched the new battery around wit the old one. (only reason why I changed the battery in the first place was because it was draining fast).

Now this is where the confusion lies.

After putting the old battery back in now my phone still WILL NOT charge. But it no longer comes up with that message, "temperature too high, functionality limited".

That battery was DEAD it had NO power left in it.

My phone wouldn't turn on unless I plugged the charger in. So the charger is DEFINITELY passing current because it is somehow keeping the phone switched on. But it is stuck on 2% and every time I unplug it it dies. It seems to be holding the minimum amount of charge required too keep the phone on whilst plugged in, but without it being plugged in the phone dies.

What on earth has happened to my phone?

P.S I am still able to transfer files to and from my PC by using the USB cable

Hopefully you can help me with a little problem:

My Huawei P9 fell. Now, no device can connect to its hotspot - two laptops and a phone say "Connection not possible", another phone falsely claimed "Invalid password entered" (and when i removed the password from the hotspot the error message switched to "Connection not possible" as well). The day before the fall hotspots were working just fine.

Also, each time I restarted the phone some settings were mysteriously reset. First I see a pop-up message reading "Some applications require data connection. We recommend hiring a data plan." - even though my provider is being recognized and I have working mobile data. Then, after every restart the 24-h-clock format, the percentage display of the battery, the auto-rotate and a lock-screen setting are reset to default. One time, I changed the SSID of the hotspot and after the reset it was just changed back to default.

After I took out the SIM, I tested if the settings reset happens without SIM. It did not. After that it did not occur again with inserted SIM card, neither. However, the "You should get a data plan" pop-up still happens and the hotspot still doesn't work.

How can I fix this problem, or more specifically, make the hotspot work again? I have tried a bit with different APNs, but to no avail. I also did a network setting reset.

I am not even sure if the issue has to do with software or hardware.

Any help is very much appreciated, thank you! :)

Kind regards

I went back to the guy who helped me replace my screen. He opened my phone up again to check the camera pins and he said the camera pins were fine. He even connected my phone to the old screen again to see if there might've been an issue there(?) but the camera app and flashlight were still not working. He insists that it's a software issue and that I need to factory reset my phone, which I'm all but ready to do, but I wanted to reach out into the community and see if anybody had other ideas about what the issue might be.

It's a Huawei P9 EVA-L09. My camera and flashlight were working absolutely fine before the screen replacement. (Everything was still working smoothly except for the screen, really.)

Thanks in advance for any help!

anyone facing the same issue? when open google map it can locate the initial location. but once started the navigation it will not move / detect the location, or keep detecting inaccurate location like around 10-50m away from current location. become so laggy in detecting location and keep rerouting due to inaccuracy of location.

but once in a blue moon it will be back to normal and function like normal again.

Best Regards,

There are no repair shops where I live and I would like to try to fix it via manuals.

Would it possible to replace the LCD display with a repair kit , for a beginner like me?

She could swipe/scroll perfectly on the broken screen. Very weird?

however now the LED does not work (i open the flashlight app and nothing happens), Nor does the camera app work. When I open the camera app, the app dies and doesn't open. When i try an app that would USE the camera, there is an error message saying "the camera is in use by another application".

So-- I'm unsure if the camera or LED worked prior to replacing the screen. I honestly didn't think to check. The screen was damaged pretty badly.

Ideas.?

I have called Huawei US and as this model (the p9) is an "International model" they (Huawei) will not help. Which is weird. but alas true.

I know that this phone is not in the US yet, but it seems that if I can't fix it, it is a big risk to buy another knowing that if I break the screen, im screwed.. any ideas..?
