Erratic ghost touches. Help!!
I recently got a refurbished Nexus 4 from Google beginning of April. I been having minor issues ever since getting it but i never bother to call them or get them to send me a new one since my warranty was expiring around end of April. So since last week, my phone started having these crazy erratic ghost touches lasting either a few seconds where i'd turn off my screen and it goes back to normal or it would last a good 10-15 minute non stop. I rooted it recently and i tried to do a google support. They suggested factory reset, did that. Re-image the device to original state, also did that. The problem continues and its getting a bit annoying. I noticed the problem starts a lot more frequently when the phone is hot or when the battery is below 50%. Is there anything i can do to make this go away or less frequent? Thanks
Also google suggest i call LG to get them to repair it and have my wallet raided. I prefer not to. Since i feel like they cheated me by giving me a crappy refurbished phone that has hardware issue just like the one i bought from them.
