Ever since ios 8, my 5s has been super slow & glitchy. Both of wifi & att lte. I get errors on apps like "unable to connect to network" on lte. On wifi , everything takes long to load, freezes, and is generally slow. I have to close out apps to get them to work again. Ios 7 had no problems, my phone was essentially perfect. Should i go back to ios 7 in the meantime? I dont really want to wait another month for 8.1 when i cant be sure they address these issues, as they werent addressed in 8.0.2. Or anybody know any fixes?
