1- Battery connector on mainboard
2- Battery cable connector
3- Bad battery
Permanent Fix:
1. Pressing middle of Tablet where battery connector stops flickering for moment.
2. Developer options - "turn off hardware overlays" (also enabling "force GPU rendering" might help)

Accelerometer issue

Hello guys , I accelerometer which tends to the right when the terminal is located horizontally :

In gaming the thing is pretty obvious . And from a terminal I paid € 400 these things I do not like at all.
I found a thread where we talk to do a hard reset and block the upgrade of Play Services . But I think it is a very stupid solution .
Are you aware of alternative solutions ? I also tried to calibrate the sensor with the menu * 808 # # but I always get an error (Device is busy ) .
OnePlus is aware of this bug ? You know if there will be a solution in the next update ? It worries me to see users with this problem by OxygenOS 2.0 and despite the various updates to the 2.1.1 has not yet been solved .
I'm pretty disappointed .
Hi, I'm having the same problem; about 8 degrees tilt to the right on horizontal and accelerometer test failed (device busy).
I think it may be hardware issue, since I have this problem on Oxygen 2.1.1 as well as Hydrogen rom.
OP, did you find any solution?
Also, anyone reading this thread can check your sensors and other stuff from service menu *#808# (GSensor) .
Edit:
It's an issue with Google Play Services....
Disable GPS then recalibrate from service menu, then re-enable GPS.
Solution found from oneplus forums.

galaxy s5 rare charging problem

hey guys,
i have the wiredest problem.
i've phurched a new galaxy s5 and when i connect it to the charger, a charging icon appears but the battery % dosent go up, only down.
i've downloaded many battery analysing app and theey all seem to think that everything is fine, that the current flows and all, but the % dosent go up!
i switched a battery and a cable and its definitly a phone problem (i can charge the battery in another phone)
some suggested that i sould replace the charging port but it looks completly new and fine, and also cost quite a lot of money to replace.
is there any other soultion?
thanks!!
Sorry I encountered the same problem on my old s3. I finnaly solved the probleme by changing the micro hdmi port. Sorry I know you won't here this but i search everything. I replace myself it's not so hard. I do it because my s3 was in ending life.
It does sound like the charger port.....
The replacement parts aren't that expensive (under £10 off eBay).
Just make sure you get the right one....
Look at the pictures......

These parts are device variant specific......
It would probably be a good idea to match 'rev' versions too.....that was certainly the case with the S2....If the wrong rev version board was put in, it led to signal problems etc......

Improve Battery After Nougat Update

i have seen many comments in different threads about having poor battery life... i myself have faced this issue.. with my battery dropping like 5-7% while it's ideal to.. so many people suggested to full wipe my device but along with it i used a software BK DISABLER(SAMSUNG)...
i disabled all the apps along with samsung account(i checked shealth was still working after this but then i removed it seeing the number of services it had)
given in this link..
https://forum.xda-developers.com/galaxy-s6/general/safe-to-debloat-s6-threads-t3090383
please check the second cmnt by @lizaSB..it's more detailed and apps are easy to find.. whenever you disable a bloatware be sure to check you have disabled the services given in it(using BK DISABLER.. obviously)
I don't know whether a seperate thread has been created for this or not... but after nougat update this really helped.. my batter falls like 0.6 or 0.7 % perhour when it's ideal...
I know many scripts are availabel for doing this but that requires root.. this app doesn't requires root privilege .
I feel battery for the S6/N5 family improved with Nougat, while the S7 line battery was negatively impacted. Moving to a spare S6 I had, as I had to send my S8 in to replace my screen, I'm getting quite decent numbers for a 2-year old phone that was used for most of that time by my mom (she changed phones recently).

Main Camera Problem - Black and White vertical lines

Hello to you all!
After I've searched a bit in this forum, I couldn't find someone with the same problem.
Issue: When entering in main camera, vertical white/black lines appear, no other image is present. (wide and selfie work as expected)
See attached files.

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Cause: I filmed a terrible rain with the phone (which was supposed to be waterproof and mil-std-810g compatible), but the next day, the main camera lens, not both back lenses, was steamy, a couple of hours lates, I could only see the previously attached files when opening the camera.
Workarounds tried:
1. Reset to factory settings (no viable result)
2. Reset to factory settings via power menu (Power Button + Vol button), nothing good happened
3. Tried other camera applications --> usually the applications crash when opening them
4. Did some tests via the secret menu, but the results are inconclusive
a. when not moving the phone, all the things pass
b. when moving the phone, some fail, some pass
I was thinking to install another image (the phone is with the original software)
Other things to mentioned: the phone has never been opened, it has sustained other rains and water dives (not salty).
Please advise!
Thank you!
Try replacing the camera module, ebay has them for under 15€
Oh, replying now, it was the camera module, it got wet and didn't worked after. Great phone though.

I think my phone got a virus? Very weird bootloop/stuck bootloader

My ZE553KL (I use it as a home device control, small tablet) keep loading/reloading for 3 hours now. I CANNOT SHUT IT DOWN. everytime I have this vibrate boot, ITS SUPER ANNOYING.
It show the bootloader then reboot, then show the bootloader and so on. Buttons are unresponsive.
Only think I can do is press up and get to screen number 2 for exactly 6 second (my computer then recognize it).
I cannot remove battery (hello soldered battery). or shut it down, I guess at some point It will drain battery but.
I have no idea what is happening, please help?

Ouch
Play with it. Proper button sequence and timing is everything. It's easy to not hit the right button at the exact moment. Allowing the battery to auto shutdown may break the cycle. Don't attempt to solder the battery without a good iron and skillset. You need to be fast about it.
If the OS is pre Pie it's suspectable to rootkits that require a reflash to erraticate.
A hardware failure is also possible.
A bad coded 3rd party apk can also boot loop you. That's worse than a normal boot loop though.
It's definitely corrupted... hopefully someone here who has seen this before and/or knows more about that line of phones advanced troubleshooting can help you.
