Hi. I just wanted to point out - in view of the next update - that the proximity sensor is not working well. When I listen to voice messages on WhatsApp, the screen suddenly turns on and I end up pressing various buttons and ending up in other menus; sometimes, the screen does not turn off at all and I have to do strange things, like putting my hand on the phone or shaking it.
In addition to this, then there is another annoying problem related to the touch: when I type quickly (so always) the screen is not always very responsive.. it often loses the touches and I have to retype
