I have submitted about 5 claims in my lifetime through the carriers. IMO a cracked screen makes the phone still usable so, it would not be covered. Does Wells Fargo cover water damage?
I had a run-in with Samsung over my Galaxy Gear S. I had a problem where the charging cradle kept breaking on a device that I had owned since December. Just about every month for about 4 months, the charging cradle would break. I wound up buying extras from Amazon to hold me over while I shipped the other one back. Then one day, the lip on the watch where the cradle attaches broke off. Samsung refused to cover it saying that it was not a hardware issue and I had not bought the replacement part directly from Samsung even though, I bought the part from Samsung, it was shipped from Samsung but was ordered through Amazon.
I spoke to supervisors, managers, etc.. and it went no where. They shipped me back the device and it still sits in the drawer.
