I have an HTC One M7 I received back in Aug of 2013. Since then I have had two additional units possibly going onto my 4th. First I must say beside the issues I love this phone. But the issues have been numerous to say the least. Issues now are as follows:
Battery life since upgrade - horrible - maybe 7-8 hours before at 10% or under
Messaging App - lags awful - have archived messages and deleted but still seems extremely slow for a messaging app - imessage is much better I must say
Data Quality - phone constantly switches in and out of 3G and 4G and sometime no G randomly
Any help on these? Also is it even worth moving to the M8 if given the opportunity? Manufacture warranty runs out Aug 30th. Trying to get this resolved before I'm stuck. Any help would be greatly appreciated.
