Phoenix Auto PX6 13.6"

Hello, Well.... after only being installed a few days - some crashes - odd behavior - the unit seems dead...

I was changing the "Car type" image per their instructions - basically a new image file with a particular name on the flash root of the OS - reboot - However, I think - almost certainly erased a file when trying different images.

a reboot worked - and the radio functioned. Seemed fine...

However, when I parked - and the radio powered off - later when I started ....................the car - NO screen. (basically a hard reboot)

BT did connect to my phone - so the radio is working somewhat.

I can hear audio

Backlight is on.

Reverse sensors work - and I can hear the audio.

No images.

Reset button has done nothing.

Being a fusion hybrid titanium - I have NO physical buttons. No HVAC, Radio, seat temp, backup camera -etc just a big black slap of glass.

Is a bootable recovery image possible to restore it to factory? Phoenix support doesnt answer - emails, calls - etc.
[Android Head-Units] Joec93:
When did you have this in your fusion

I'm having the same issue same car
[HTC Vox] skchattha:
is it true in 6.1?

I tried lot of tools like moblue, file acceptor, bluezard etc. but no tool is able to receive files directly on storage card. Always files are saved in /My Documents.

Even if you disable "Receive Incoming Beams" in Connections Settings and run the tool, it does not work at all.

So only working solution is:

Enable "Receive Incoming Beams" in Connections Settings and receive the files in /My Documents using native bluetooth support in 6.1, then transfer to storage card but it's a challenge if you are already short of main memory.

In 6.0, every tool worked flawless.

Are you facing same? or any workaround? :confused:

Hello,

I know for example that app like Cpu-Z finds the device information on the build.prop but yet I can't figure out where does it gets the information of the Gpu.

And is it possible to change the Id of the Gpu just to experiment?
[Magisk] LastQuestion:
Hi,

My memory issues and a hard week led me to forget I needed to uninstall magisk manager adn 'restore image'. I've never had a rooted phone before, so I'd never done it before. Got lost in the 'big pile of problems' and google kept nagging to 'update'. Sigh.

Last thing I want to do is try to figure out how to migrate all my data and apps (I'm expecting Google Recorder is likely to prove a PITA to get everything 'moved'). So I'm wondering, is there a simple/easy way to get magisk root back and active without wiping apps/data on my Pixel 4a 5g since it was already rooted prior to the OTA security update?
[Magisk] Didgeridoohan:
The only consequence with applying the OTA should be that you're know updated and rootless (since the boot image would have been overwritten in the update)... Just patch the new boot image, flash it and you should be up and running again.
[Magisk] LastQuestion:
Ah. Thanks. That's simple enough and sounds like I don't have the emergency I was dreading.
[Magisk] LastQuestion:
Well, I rebooted the Pixel 4a 5g, and then it would get stuck on G logo and wouldn't load the system.

So I couldn't use latest magisk manager to create a new patched boot img. So I tried to flash the patched boot img I still had on my PC from december as the Factory image firmware is still the same right now as it was then. Now when I try to boot I get a boot loop that doesn't get to the G logo even.

Wondering what to do now... I guess it wasn't so simple after all.

Edit: I tried flashing the original boot.img. No change. Near as I can tell next option would be to try to side load an OTA update, but the Pixel 4a 5g doesn't seem to work via ADB...

What's weird is that the pixel was working before I tried to reboot it initially. Now I can't get into recovery or rescue mode either. Just have a boot loop. Can get into fastboot still.

Edit 2:

I had the wrong factory image. Got the right one, for january. Flashed boot.img via fastboot. Back to 'stuck on G logo' like before.

Edit3:

Seems stuck in fastboot mode now. When selecting 'start' fastboot just loads up again.
[Magisk] LastQuestion:
I tried adb sideloading OTA update. Didn't work.

I tried flashing factory image removing "-w" modifier from flash-all.bat. Stuck in boot loop on googles "G" logo with the loading status bar underneath.

Hoping there's still a way to avoid a factory reset, but wondering what next steps there are.

Is there a subforum better suited to maybe getting this question answered?
[Magisk] Didgeridoohan:
Sounds like you've gotten to a point where it's better to ask for help in your device's forum, but I've seen you're doing that already.

Hope you get things sorted...

Edit: since it's always possible that modules mess up a system update, have you tried the adb command to remove modules (if boot reaches a point where adb is recognised), or booted to safe mode to disable all modules? You've got some details here:

Thank you for that guide! I used it to calibrate my A70 Battery (4000 mAh) which i use in my A7 2018 (original 3000 mAh). I did the second method and had to do the 3 steps about 7 times. I had to restart my phone after every try to get my real percentage, it usually jumped from 100% fully charged to 65%.
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] kingrohan:
Hello, I followed the first method for my tab S4, it was shutting down instantly as soon as it reached 15- 20 %. but it happened sometimes, not everyday.

So I did as you told in the first method, but I think I probably messed up somewhere, Now what is happening is, as soon as it reaches above 60% during charging, it slows down to like how it slowly charges when above 90%.

Battery backup is as same as before, so that it means its reading 65% as 100%.

How can I rectify it, battery is getting fully charged as 65 - 70%.

How can I reset the gauge again so that it shows correct percentage.
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] Mightx:
Try repeating the procedure again. It might work it might not. Sometimes phones might read way off so try again. Drain it then repeat steps

[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] Emre67511:
I am not sure about this but I think I found a method to skip step 6. and immediately get 100%.

You just have to download an app like AccuBattery or something similar and look for "charge current". I noticed that when my phone reached 100% the charge current was still very high for like 20 minutes or so and after that it dropped to a low value near 0 indicating that the battery was full. If the app is legit than you could use this method to charge the phone to your real 100%.

I quick started once after this method and the phone was still at 100%.
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] Mightx:
Yes the voltage and current stay a bit high as if it were plugged in even though it is not and that is for a few minutes or so, but after that it would normally drop to more or less its "actual" readings unplugged. Personally can't vouch for accubattery and the like, but any app that reads the sensor that is responsible for battery voltage and current should more or less be the one to look at, of course different apps might poll differently so updating the info might take time and there may be variances but if using apps like these help in determining when the battery is at around 100%, then sure you could use this method.
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] jonatpd:
hello i have followed the 1st and 2nd Method for my s9 plus phone because my phone drain to 5 percent in a blink after it reach 15-20 percent or even dead... but when i used the code *#0228# my battery percentage didn't change at all and the both method didn't fix the problem at all... i have suffer this issue since 3 months ago, do you have any suggestion? thanks
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] Mightx:
As I have mentioned in the guide, when none of these work and you are sure that you followed each one correctly, then sadly it might be time to replace your battery. If for some reason a battery replacement still doesn't fix it (which in most cases it should), then it might be your circuit board in charge of power management and charging that may be faulty, although in most cases battery replacement alone does the trick.

Hello everyone. I have a question for you all. So, got a new phone a few weeks ago and I've noticed lately that after I charge it from, let's say around 10% to 100% and unplug it a minute or two after it reaches 100%, it stays on 100% for longer than it should. It stays on 100% for at least 15-20 minutes of active screen on use (no matter how I use my phone it stays on that 100% for quite some time), and after that the next few percent fall down quicker than they should - for an example after that initial 100% drains to 99, every 1% drains within 3-5 minutes of Screen on use until it reaches the 90-91 mark. When it reaches 90% it looks like it starts to function and drain normally. So my question here is: Can this calibration be off on such a new device?

Thanks in advance.
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] r3actor:
@Mightx I have a question :)

I bought a new 'replacemant' battery for my Galaxy S2. I still didn't put it in the phone.What would be the proper steps for starting with new battery? Should I look for a way to delete that 'batterystats.bin' (if such thing exist, on a LineageOS 14.1 which I'm using now)?

And... (since I don't know)... if I insert a new battery and (proabably) its not fully charge. Lets say ...what if its 66% charged? Should I charge it first to 100% before I starting using the battery, or should I discharge it from 66% to...zero? or 5%?

I don't know honestly what to think. On my tablet I installed an app (AccuBattery) and it warn me everytime my batter reached 85% and telling me to remove the charger. So...I'm kinda lost. I want to start using a new replacemant battery the propper way, but I have no clue what that 'propper' way is.

Can someone help please?

Thanks!

Hello.

Thanks for posting this guide.

My battery calibration issue is different to anything I've seen before. I had the usual battery problems and got a replacement battery fitted. My current problem is that the battery has more charge than the phone realises (which is the opposite of the usual problem one tends to see with a bad battery).

The battery level falls quickly from 100% down to 1% at a rate of about 10% per hour. But then it stays at 1% for AGES! Even if I leave a video running on YouTube on maximum brightness. So there's plenty of milliamps in there, it's just that the phone doesn't realise this.

I tried following methods 1 and 3 but the problem is still there.

Any suggestions? Thanks in advance.
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] Prokholeg:
You will need superuser rights to properly calibrate the battery. We discharge the battery to 1%, then connect the switched on phone to the switched on charger and charge up to 100%. Not turning off
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] Mightx:
I mean, you could try if calibration does anything in your case. But I suppose that's more or less normal behavior since at very high battery percentages (beyond 90%), the software on your phone has a harder time figuring out how much juice is still remaining so the draining seems to slow down at the higher percentages and tends to speed up at the lower percentages (below 40%), which in net effect just gives you the same battery life just like if your phone were to drain evenly across all percentage levels. So imo, you shouldn't worry much about it.
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] Mightx:
I've experienced this before both with a battery going bad and a phone with a good battery still but with faulty power delivery circuitry. You could try all the mentioned methods to try and see if calibration does anything to solve your issue, but if all these fail, then it may be time to send in your phone for repairs since you mentioned that your battery is new anyways so it may be something wrong with the power delivery.
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] Deleted member 10763927:
Thanks for the reply. Yeah I figured after a while that it's probably alright since my phone's not dying at around 10% left or just starts discharging super fast.
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] dafii:
Hey! Afew days ago I replaced the battery in the S10 +, do I need to do a battery calibration or can I skip it? or only factory reset?
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] Mightx:
Usually you just use your phone normally and it should automatically settle after a few charge-discharge cycles. In this case, you can skip manual calibration.
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] Mightx:
After a battery replacement, just use the phone normally and after a few charge-discharge cycles, it should automatically settle down and start running normally. In this case, you don't need to go through manual calibration.
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] s3korn:
guys are you aware of the fact that if you replace the battery you have to reset the batt_cycle which has impact to the fg_full_voltage?

this is something which you have to do at least with the S10 series... as far as we know Samsung do the same if you give your phone to them for changing the battery for you. otherwise the new battery won't be fully charged.
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] s3korn:
uuppssss...
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] Mightx:
Might be a similar process to resetting the fuel gauge but that's my take on it. It could be a different process altogether and applicable only for the newer Samsung phones. Maybe they are resetting the charge cycle count to mask how many times that battery has been charged and discharged but that's just speculation.
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] tomzzi:
I tried method 1. Battery reached 5% then i dialled number. Pressed quick start then phone died immediately.

Does this mean i have bad battery?
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] Mightx:
Not necessarily. Sometimes if you are at a very low percentage already, resetting the fuel gauge may shutdown the phone as it probably makes the percentage 0% which triggers the auto shutdown. At 5%, I really wouldn't worry about it but at higher percentages >10%, then maybe the battery is acting suspicious.

[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] Mightx:
The availability of USSD codes on your Samsung device depends on the firmware/ROM it is running on. For Samsung, stock firmware have the best chance of having complete USSD codes, then next are ROM's which are Touchwiz or OneUI based. USSD codes are completely different for Stock android firmware and AOSP based firmware as they have their own set of dialer codes.

As for your problem, you may want to check if the phone you purchased is running the official stock firmware. If it is, then check for firmware updates and ensure it is on the latest version available for your region and model.

[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] lstic:
I wonder the same. I'm on latest update on S10e. Last year i used this code with no problem, but now it doesn't trigger anything.
[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] Mightx:
In order to access a dialer code, the firmware must support and contain it. You'd notice most of these codes missing from some OneUI custom ROMs which are advertised as "light" or "for gaming" since devs behind these ROMs try shaving down as much bloat as they can. Also, for most GSIs, since they are not OneUI or Touchwiz based, they would have their own codes but without the Samsung-proprietary ones like the fuel gauge. Try using apps from the Playstore that reveal your phone's current secret codes to try and check if the fuel gauge code (*#0228#) is present. If not, then you have your answer (your recent update may have removed it either accidentally or intentionally, so rollback if you can and if you need to).

[Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)] lolli.filippo:
You shoud try to discharge the battery until the phone dies, than enter in recovery mode and let it dies again.

After that plug it to the charger and let him charge up to 100% and let it plugged for 20 minutes at 100%

Start the device with the charger plugged and when it says charge complete you can unplug it.

After this you can check your battery stats on ADB with the following command

adb shell dumpsys battery

You can get informatins like

-Charge counter = mAh in your battery releted to your battery percentage

(if battery is full charged, the output is your battery capacity in mAh)

-mSavedBatteryAsoc= Battery Health in %

-mSavedBatteryUsage= Battery Charge Cycles

If you need help reading these stats take a screenshot and I'll pleased to help you.

Make sure to disable fast charging in Device Care before running this process

I link you a OneUI optimization guide if you want to go gain some extra juice from your battery, but use it carefully and USE ONLY what you can understand

Doing the *#0228# and *#9900# tricks made my genuine replacement battery for S9 worse. I ordered a genuine samsung battery and After 1 week of trying the calibration steps you provided and which i followed strictly my new replacement battery drains very quickly from 100% - 90% in less than 8min of usage, much worse than the 3yr-old original battery that i replaced.

On the other hand, I have come across an app i downloaded from APKPURE and it seems it has completely fixed the fast drain issue and the battery seems to be perfectly calibrated now.

I dont know how it works but it seems to have accurately calibrated the new samsung s9 battery even without rooting it. The app can detect if my samsung phone is rooted or not then provides an option to calibrate it even if the unit is not rooted. I dont know how but i can guarantee that this solved my fast drain issue with a brand new genuine replacement battery from samsung.
