so i swear the thunderbolt is the worse phone ive ever had (and ive had ALOT of phones), ive been through 6 so far on number 7 and about to wind up with another one. first was bad out of box it lasted 15 days till they finally said hey we will replace it second was bad sim reader third was bad battery terminals and next 3 were dim flickering screens that went out now this one is the biggest POS ever. Ok so lets start off this way NO I AM NOT ROOTING MY PHONE IF I ROOT IT I CANNOT GET IT REPLACED UNDER WARRANTY..and yes i know of ppl who have gotten screwed like that.. ok now that that is out of the way. So my phone is ungodly slow. Ive tried anything from battery pulls to advanced task killer.... this thing just sucks hell on advanced task killer half the programs pop right back up. When in text messaging its so slow its rediculous sometimes waiting 5 mins for a text to open. Like right now i have 3 text convos all with less than 100 messages and it keeps force closing. My phone runs normally what it would run like if it was plugged in ... Sluggish n horrible when its off the charger now you put it on the charger you cant even use it. Whenever i click on one conversation it pops me to another over and over and over again.... It makes me wonder why i bought this phone in the first place.... my original droid ran better than this thing does.
