Hi all, I've tried searching for this fault but none of the results seem to match my problem. Has anyone else seen this? If I use any mapping or location apps with wifi on/mob data off/gps off, it shows me as located in Riyadh when I'm in the UK. It's a bit of a pain if I just want to check a map from the sofa, but the real issue I noted was that Lookout security located it there as well which means if the phone is knicked and I do the find my phone, it's useless. Interestingly, the only app that locates solidly, I'm guessing by cell tower, is the Cerberus security app (I installed this after binning Lookout.) Phone: Galaxy S4 GT-i9506 (rooted) Fault conditions: wifi on/mobile data off/GPS off Recently upgraded from S2 which didn't have this issue.
