LG-P698 Help Please

[Eg_Sword]

Hello all , this is my first Post and I hope that everyone is okay
I bought a LG-P698
I noticed that the strength of the network is weak from the first day and tried to return it did not happen
-------------
With time beginning to show some of the things
1 - Lighting of the screen without touching it for short- periods and then started lighting periods exceeding even began to light up so heated and end up charging the battery and sometimes alone or when you restart it goes to a yellow screen in emergency mode
2 - despite the emergence of the network signal people call me find me out of service
3 - When you connect to the primary response from the speaker even though he is not enabled , which obliges me with every call I activate the loudspeaker and then cancel the activation to speak normally
4 - only rarely does not respond to connected to the computer , although the original use of the cable can not be open Les memory nor felt by PC Suite software

I thought in the beginning that virus and revealed programs but did not find anything
Sent for maintenance and they said to me that they had a firmware update
And a few days after he returned back to him the problems in ascending
I made a hard rest but no good news, it is the same by time its problems come back

Firmware it is the last Arab V10g
I noticed from the first day that there is a lack of this firmware when she saw the file on YouTube , where they found the English version , the first choice in the tools is update via Wi-Fi, this is my choice even after the update has been in agent

Inquiry : Does this happen with all the owners of this device or this is special case ?

Help :

2 - Can flashing device in other language can help ? if this will make it stable I can use it in English language
