Hi all!!! IOS 7.2.1 causing problems, Help

By the way...i have downloaded IOS 7.2.1. several times and reinstalled without success.

After 2 days using the new update i can tell, that the update seems not at all desined for iphones 4s, but for 5, 5s and 5c. This conclusion is made out of that the system in 4s became unstable and slow. This Means that Apple like many other electronics producers are careless about its older costumers and want them probably to buy a new phone as Windows/microsoft has done in a long time producing updates that make computres slow and unstable.

I have found out that the update does not Work good with the Camara, as mention earlier. I have to turn the phone upside Down to make it Work with the bottons in the lower side of the screen. This problem repeats again in many apps, like Nike (running program), and this *****. This seems like the update have overdimensioned the phone, like the screen should be bigger than it actually is....ahhhh maybe like the 5 series!!!!

On the other side, no other complains about this topic/issue/problem yet, makes me wander...why not...it can not be only me.... i have done the update many times.... starting from the phone its self.... from itunes (Windows compatible)..... from my macbook air... and nothing...same F* problem.

The phone is a working Tool...i don't have time to this kind of UPSSSSSS!

I had the idea that this fórum would help finding a solution to my problem, but this was obiously not the case. At least is there not a place you (high degrees users) cam recomend to find a solution????
