The way Samsung has been releasing Neo / Lite versions of existing devices, with the Galaxy Note 3 Neo being the latest device, many have probably been wondering if the Galaxy S5 will get such a lower-powered Neo variant as well. It's certainly possible, as these Neo devices are part of Samsung's plans to offer something for those that can't (or don't) want to spend on the standard variants, and the SM-G800F, which was recently shipped to India for testing, looks like it could be the Galaxy S5 Neo.
The SM-G800F appeared on Indian import tracking site Zauba, and a model number quite close to that of the Galaxy S5's (SM-G900F) suggests it's a variant of Samsung's latest flagship. A Galaxy S5 Neo is the most likely suspect, given the similarity in unit prices of the SM-G800F and the Galaxy S5 (SM-G900F), though since the listing doesn't offer any hardware details, we'll have to wait for now to find out whether the SM-G800F really is the Galaxy S5 Neo, or something else entirely.
