Bluetooth Keyboard and mouse not working properly. Please Help! Bluetooth Problem

[CharlieLeiva]

I just recently bought a used Galaxy Note Pro 12.2 SM-P905V about 2months ago. Everything is fine but until now where I tried connecting a new Logitech bluetooth keyboard and a bluetooth Microsoft mouse.
Mouse Problem:
There seems to be a lag with the mouse pointer where it would freeze for half a second then it would go very fast. This happens constantly. Tried it on my laptop and the mouse works perfectly there.
Keyboard Problem:
After typing 3 words on the Note Pro, it would repeat a letter, or an input I push many times. For example, "My name is Chhhhhhhhhhhhhharlie". I tried using this keyboard on my Samsung S5 phone and my laptop and it works perfectly on those devices. I bought this tablet for school work like writing notes and typing papers so this is a disappointment.
So the problem seems to be my bluetooth on my SM-P905V, what can I do to fix the problem?

Bluetooth is integrated circuit on this model and it's used, failed bluetooth or wifi is nothing to be surprised.
Try to clear data and cache in Recovery Mode or Factory Reset.
Your mouse and keyboard are working fine with other devices so the problem is from BT connection. It's impossible to fix as many components are involved and mainboard has to be replaced.
I have one Note Pro with not working BT, it doesn't bother me as I rarely use BT for anything.

I have the same issue intermittently, and unfortunately its well documented that many others have had this issue as well.
It only seems to be an issue when you have both a keyboard and mouse connected.
its like they interfere with eachother a bit intermittently.
if you use one or the other they work fine in my experience, even using one wired and one wireless fixes the issue.
I switched to using a wired keyboard and mouse but I've also found just using the keyboard (wired or wireless) works well too as the touchscreen works pretty well for mouse input even for teamviewer, though I understand your frustration with not being able to use both easily.
