Iphone 5s écran bleu, reboot

Question

Bonjour,
J'ai un Iphone 5s depuis 2 mois.
Durant c'est deux mois j'ai eu deux mises à jour (version actuelle 7.1.1)
Mon probléme est le suivant :
sans aucune raison et utilisation particulière, l'écran devient noir avec l'icone apple puis devient tout bleu, aucun des boutons ne fonctionnent à ce moment là
la solution trouvé est de faire un reboot en appuyant en meme temps sur le bouton home et marche/arret
J'ai trouvé des forums qui ont le meme souci du à Iwork, une application que je n'utilise pas
Cordialement

Could it be the A7 64 bit and logic board is too much cpu for the 4 inch sized phone ? Usually bsod's happen for any of a number of reasons ? Defect in a memory register ? Not enough battery power ? Short somewhere ? The iPhone 5s is passively cooled. Then there's always a buggy application ? There was a day when G4 and G5 Apple computers ran much warmer than pc cpu's from Intel & AMD ? Thus a reason why Apple moved to Intel cpu's ? The A7 is also going to power the next gen iPad ? Perhaps even the MacAir ultralight notebooks. Makes no sense to not have more powerful cpu & infrastructure to power those ? Any smartphone that is passively cooled uses the aluminum case to cool and dissipate the heat over the entire unit and use the smartphone as a 4 inch cpu cooler ? I have a HTC One and when I use an after market battery charger, the larger battery sets off overheat warnings during charging, especially with a Otterbox case cover to smother and keep the heat in. The One has a 4.7 inch aluminum case and larger battery too, might cool better but not as effectively as anticipated in a design. No bsod's but it does get quite warm on a hot summer day at times.
