My ACER A1 liquid, 256MB shows strange behaviour: The flight mode is switching on and off automatically (approx. every 5 seconds), totally on its own. The message "no service" appears and disappears and appears and disappears... In the network settings the checkbox for flight mode is switching on and off also every 5 seconds.
This occured first time in December with Ainillia 7.2 final v2 ROM, after one year of use. I decided to install a new ROM and used Master_T's 7.2 Remix v4c. This ROM was running great for 4 weeks now, but today the strange problem with flightmode returned
I already tried to reduce overclocking to default values and I recalibrated the battery. Of course I tried to activate and deactivate flightmode manually, but nothing helped.
SIM Card is working fine, PIN is accepted and the SIM Card icon disappears some seconds after reboot and login. I tried the card in another phone also.
I do not want ro do a factory reset, because I want to keep my current settings.
Any help appreciated!
