ONE&ME , via OnePlus 7T , May 15, 2021 : Hi there, I hve been using 7t since 7 months & there are some issues I have been facing 1) Both sim lose network & after some while comes to normal resulting in battery drain & UI not responding message on screen. 2) Use of single sim, no problem in network but phone lags a little bit, still the heating issues prevails. 3) Phone is becoming unresponsive, slow, laggy effect. 4) temperature of phone rising due to all this issue I have a secondary phone so there is no load on this device. Can someone explain of tell me the reasons for this.
