I am considering upgrading from my Samsung Exhibit II 4G T679 to a LG Optimus F3. My main reasons for upgrading are: 1. Faster Dual Core CPU rather than a single core CPU. 2. LTE speed. In my area T-Mobile officially has LTE. 3. Larger capacity battery on the LG Optimus F3. I mainly use the smartphone as a phone, to check EMail and limited web surfing. I have a 7 inch Tablet which I sometimes Tether to my smartphone. I feel that the faster phone together with LTE will make my web surfing with the Tablet much better. I don't install a bunch of Apps. My Samsung Exhibit II 4G T679 currently only has two Apps added (An Antivirus App and a Tethering App). I have seen a lot of people complaining about a lack of built-in storage space on the Samsung Exhibit II 4G T679. I plan to use a 16 GB or 32 GB microSD card. Do you think that the LG Optimus F3 will be a good choice for me? Is it easy to store and access files to/from the microSD card? Thanks in Advance.
