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

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 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!

So what could be wrong?

But when I finished and plugged it… it said that battery was on the 36% and Fast Charging…. but a couple oh hours later it says (while still connected and Fast Charging) that its on the 16%!!!

I turned it off and I will leave it the whole night charging. But do you know what could have been wrong?

after writing this message (couple of minutes), it is still on 16%. I strongly believe its not charging at all…

Thank you!

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.

So my screen isn't badly cracked, I can live with it, it's just overly annoying'so I'm looking at getting it replaced. A repair shop near me quoted 90 quid and a day or two without my phone. Due to circumstances, I can't allow that and 90 quid is a bit much so I'm doing it myself.

The touch function is fine and works very well and there is no missing pixels or impairment in the graphics. Literally just the glass which is cracked, nothing else is wrong. What will I need to replace?

Thanks.

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

I have replaced the LCD on several P9’s but the last two i have done have had a problem with the touch response after replacement.

The touch works on entire surface but it seems as if you do a fast swipe the phone does not registrate this, but only slower swipes.

I have tried different LCD’s but same problem.

Anyone seen this? Is it software related perhaps?

Inside the bag was my Huawei P9 and Pineng 10000 mAh powerbank, both of which were connected to each other via cord (bc I was charging, real stupid of me). The Pineng didn't survive because the other port was left open and it resulted to the powerbank spewing this orange-y liquid. Luckily, my Huawei P9 survived, mainly because it's charger port was covered with the charging cable.

I figured that my phone was okay (because it opened up, again, very stupid) so I didn't clean it up again with alcohol or water, I just dropped it in a bag full of rice and that was that. Fast forward to April 12, I found out that my headphone jack wasn't working, which led me here. (Note that software is still 10/10)

I've completely lost hope with the headphone jack issue, because I can still use bluetooth earphones etc. What I want to know is, is it possible for the saltwater to damage my phone in the long run?
