Oneplus 2 Sensor Issue

Hey Everyone,
The Orientation and Accelerometer Sensor on the Oneplus 2 stops working for some time. But after restarting the phone, it starts working perfectly.
Is it a hardware issue or a software issue?
Is this problem common or should I replace the product?

I am also facing the same problem,
It has happened a few times and restarting the phone fixes it
As of now I am on Oxygen OS 2.0.1
So I guess its a software issue since its common.
Still I'm not sure whether I should replace by Device or Not.

Everything is running in slow motion on my S4

I've had this issue for months now and I've started countless threads in countless forums attempting to solve it:
my S4 (GT-I9505 jflte) is basically running in "slow motion". What I mean by that is that no matter what I do, about 50% of the time all animations will play back at about half the speed they normally would and any kind of input will be registered with a delay of about half a second. Animations still look smooth at about 60fps and the phone doesn't crash, it's just... slow. Really slow.
I used to think this had to be an issue with Cyanogenmod (was running the Optimized CM12.1 rom from AntaresOne & Alucard), but after trying several different builds and clean flashing countless times, nothing changed. Now I just flashed an entirely different ROM (Resurrection Remix) and although it ran buttery-smooth for the first hour or so, after restoring all my apps it has now started doing the same thing.
The fact that the problem persists even with a completely different ROM leads me to believe it must be something to do with the apps I have installed. But how do I troubleshoot this? I have way too much stuff on my phone to go through deinstalling every single app and making sure it wasn't causing the problem.
I have no idea how to approach this problem. Any help would be greatly appreciated.
EDIT:
I'm not sure if this has been happening before with CM12 or if it just started happening now with Resurrection Remix, but I just noticed that it seems to happen mostly when the device is charging. When I unplug it, 9 times out of 10 the slowness will instantly go away... is that an indication of anything?
EDIT 2
I think I just solved the issue. After discovering that the problem appeared to be caused by the charging, I tried a different charger. My original Samsung charger started having horrible coil whine a few months ago, so I threw it out and started using a generic one I had laying around. Come to think of it now, that must have been when the problem started.
I just found another charger for a Samsung phone and plugged my phone in: everything fine. Switched back to the generic charger: everything slow. So it must have been the charger. Just out of curiosity, is this a known issue? Could some kind of electrical noise from the charger be interfering with the touch screen? Seems almost bizarre that a simple charger would cause a phone to run slow...

How to fix bugs?

So I have working OMNIROM 7.1 for my device, however, weird little bugs happen sometimes such as screen rotation stopping, Mobil data suddenly not working (even with LTE+ indicator) and other little things that are fixed for a while on reboot. Is there an official way to diagnose and patch these little things?

Bluetooth Call Audio Issue

Hey everyone,
I checked the similar threads but it seems everyone else has issues while playing music. My issue is only during calls.
Very often, almost every time, I have my V20 connected to a car through Bluetooth I get a really bad stuttering during calls. It is pretty much impossible to take a call like this. Sometimes the problem will go away but most of the time I just can't take any calls through Bluetooth. This has happened on a 2012 and a 2016 Toyota Prius C.
I recently got the Jaybird X3 and I experienced the same issue. Which leads me to believe that the issue is with the phone and not the car. I have a Note 4 and I never experienced this issue.
I tried stopping the Bluetooth system app (apps?) and clearing the cache and data but the problem is still there. I mention apps because I see 2 Bluetooth apps. One says its version 7.0 and the other one version 5.30.13. It seems both are active since both have memory used in the last few hours.
I've also tried the unpairing, deleting, and pairing the phone several times and the problem persists.
To be honest the problem is really annoying to the point I've considered getting something else. It is just frustrating to not be able to take calls over BT.
Anyone else having this issue? Is it maybe just my phone? Any ideas what could it be or how to solve the issue?
Thanks
I tried the phone with a MB CLA 250 and the issue is still there.
I also noticed there is a lag on the audio both while listening to music and while playing a video. It is more noticeable when playing a video since the audio is clearly out of sync by about half to one second.
Any ideas? Anyone else experiencing this?
Or is it just me?
I can't say I've had this problem. What model v20 do you have? Are you stock or rooted (and if rooted, what ROM/kernel)?
I also have 2 system BT apps but one of mine differs from yours - 5.30.12.1
I'm using a rooted VS995 with a stock 11a rom and the NSSR 5.5 kernel.

Random freezes on official RR 5.8.5 during calls

Hello everyone!
Recently I installed RR 5.8.5 (android 7.12 nougat), along with nano Gapps and a custom kernel (Raiden Kernel at first, then switched over to HYPER n UPSTREAM). Everything is running smoothly, except during calls.
The problem is that when I have a bluetooth device connected (and acting as phone audio), if I try to switch from bluetooth audio to handheld from the in-call menu, my phone freezes and I have to restart it. It's really annoying and any help with the issue will be appreciated!
There was another occasion where something similar happened, I just couldn't close the call. It kept running in the background even though the other person had closed it and eventually my phone froze again.
Happens under both kernels, which is why I think it's from the OS. I'm a bit of a flash-noob, so I don't know how to get crash logs and stuff like that, so if you need any, you'd have to tell me how to get them.
