LG Electronics — lg mobile phones

I am in my 1st year using lg phones and they are absolutely horrible.in the past 8 months i have had to replace 2 phones, because of too many problems. Black stops developed on my screen, apps were constantly not working like fb etc.. Phone volume was going in and out on conversations, phone would constantly disconnect a conversation, phone would take random pictures on its own, etc... I constantly clean my phone with safe screen application and rag, i have a screen protector and phone protector.
I asked for a refund for my second phone and was denied and they only offered to replace phone, where i had to mail it in and be without a phone for 2 weeks. Customer service was no help, because they just read from a manual. Now in 8 months i am on my 3rd phone and its a samsung
