[Completed] [Q] bluetooth problem with acer z520 - XDA Assist

Hello
I have an important problem for me with the bluetooth connection of an app of mobile paiement wich uses an ingenico mobile terminal of paiement wich is connected to the phone.
my last phone is an acer z3 and i worked perfectly well with this. i tried the app on the phone of my husband and it works too. with my phone, every thing is ok at first when i pair the phone, the paiement terminal is paired and it appear ok in the app but when i trie to do a paiement it says there is no connection between phone and ingenico terminal.
i tried to re-install app, i tried to root the phone. i did the pairing much time without success. so i'm asking some hel here. maybe it is an acces problem or maybe should i change android version.
my version is 4.4.2, my husban has a galaxy X cover 3 with android 4.4.4 and my old phone acer z3 has 4.2.2.
if i have to change android, where could i find a rom?
thanks a lot for your answers.

Hello, and thank you for using XDA Assist!
I think something less sinister than popups and redirects being built into the ROM is going on. The first thing to do is download a root checker app, and make sure you are not rooted without knowing about it (as it will affect the next step).
The other thing to do is a factory reset. Be aware, this will wipe apps downloaded, settings, and in some cases pictures taken and other files downloaded. It will, though, keep the operating system / firmware / ROM intact (which is a good thing).
Once that is done, and basic setup is done, don't install any apps yet. Browse around with the stock browser and see if any of the weirdness has returned. If it hasn't, then congratulations, it was a rouge app. If the weirdness persists, then it could be either a clever rouge app (virus), or you may have been right after all.
If it does persist, then please add a post to this thread:
